United States Patent 3,358,298 WALL PLUMBING ASSENIBLY Peter J. Beyerle, 84 D St., Chula Vista, Calif. 92010 Filed Dec. 23, 1963, Ser. No. 332,649 24 Claims. (Cl. 4-211) The present invention relates to plumbing equipment, and more particularly to plumbing equipment used in dwelling units or in other structures having washing and comfort facilities for the use of their occupants.

Heretofore, drain and vent lines have been assembled together and installed individually in the walls of dwellmgs and like structures. The individual assembly of the l nes and their various fittings to one another at the job site represents a time consuming and relatively costly operation, with the attended hazard of leaking joints. As a rule, the wall structure is substantially weakened during installation of the vent and drain or waste lines. Moreover, the resulting plumbing assembly installed in the wall of the structure may not have its several connections for plumbing fixtures accurately located, requiring additional labor and material in appropriately mounting and connectrng such fixtures in leakproof relation to the plumbing assembly. If a wall hung toilet is to be used, the carrier for such toilet has heretofore been, of necessity, comparatrvely large and has required an increase in the thickness of the wall. Difficulty has also been encountered in providmga proper sealed relation of the wall hung toilet to its dram line fitting, with the toilet mounted flush against the Wall.

It is an object of the present invention to provide a plumbing assembly to be mounted in the wall of the structure, which greatly strengthens the Wall structure, rather than weakens it. I Another object of the invention is to provide a plumbing assembly to be mounted in a wall of a structure and strengthen such wall to an extent at least sufi'icient to enable a Wall hung closet or toilet to be firmly and securely supported thereby, as well as other plumbing fixtures that are to be connected to the assembly.

An additional object of the invention is to provide a prefabricated plumbing assembly which is economical tomanufacture, and which embodies a frame, enabling its shipment as a unit, the frame functioning as an integral brace or core for greatly strengthening a double wall in which the assembly is to be mounted.

A further object of the invention is to provide a prefabricated plumbing assembly capable of being made at the factory and delivered as a unit to the building site for rapid and easy installation in a wall.

Another object of the invention is to provide a plumbing assembly for installation in a wall that definitely and appropriately locates the outlets for plumbing fixtures to be associated with the assembly on one side or opposite sides of the wall.

Yet a further object of the invention is to provide a structure or carrier for supporting a wall hung toilet which is rigid, strong and sturdy, easy to install in the wall, and which does not substantially increase the overall thickness of the wall.

Still another object of the invention is to provide an improved device for sealing the outlet of a wall hung toilet or water closet in leakproof relation to a drain and with the toilet bowl fitting flush against the wall.

An added object of the invention is to provide a plumbing drain fitting to be used in conjunction with a toilet bowl that gives a longer Vertical siphon leg for the toilet and provides a vent for the main drain line.

Still a further object of the invention is to provide a sanitary fitting for effecting a connection between a bath- 3,358,298 Patented Dec. 19, 1967 tub and a main drain line, that allows the drain line to be located fully above the floor, with assurance that no water or effluent can back up into the bathtub.

Another object of the invention is to provide a plumbing assembly to be installed in a wall that embodies a device definitely locating the hot and cold water connections for a clothes washer appliance, both horizontally and vertically, as well as the drain for the appliance, the device also serving to brace the frame portion of the plumbing assembly.

Another object of the invention is to provide a plumb ing assembly to be installed in the wall of a structure that includes the combination of a supporting structure and drain pipe and hot and cold water connections to-a lavatory sink, or the like, which definitely and accurately locates the connections relative to the Wall to facilitate appropriate leakproof attachment of the lavatory or sink to such connections.

A further object of the invention is to provide a plumbing assembly to be installed in the wall of a structure and embodying a device for supporting mixer and diverter valves for a shower at minimum extents of projection from the wall, the connections being appropriately centered both vertically and horizontally for installation of the several valves.

This invention possesses many other advantages, and has other objects which may be made more clearly apparent from a consideration of a form in which it may be embodied. This form is shown in the drawings accompanying and forming part of the present specification. It will now be described in detail, for the purpose of illustrating the general principles of the invention; but it is to be understood that such detailed description is not to be taken in a limiting sense, since the scope of the invention is best defined by the appended claims.

A plumbing assembly A is disclosed in the drawings as having been installed within an interior wall B of a dwelling unit C, separating a bathroom D and a laundry room 3 E. It is to be understood, however, that the specific use and location of the assembly in the drawing is for illustrative purpose only, and that it can be used with plumbing fixtures in other rooms of the dwelling unit or structure, or it can also be used in connection with fixtures disposed on one side only of a partition or wall.

The dwelling unit C disclosed includes floorjoists supporting a sub-fioor 11 on which a finished floor 12 for each of the rooms D, E can be disposed. The dwellingunit illustrated also has an exterior wall F of the bathroom and laundry room. This exterior wall may have the usual vertical studs 13 appropriately spaced from one another to which outer wall members 14 are secured, as well as inner wall members 15. The partition or dividing wall B between the laundry and bathroom is of a dual type, including opposed sets of aligned vertical studs 16 appropriately spaced from one another and resting upon and appropriately secured to opposed plates 17 suitably fastened to the sub-floor 11. The upper ends of the studs 16 are suitably attached to a ceiling or roof structure thereabove' (not shown), in a known manner.

The plumbing assembly A comprises a prefabricated unit having drain lines and vent lines for the several appliances in the bathroom and laundry room, as well as the hot and cold water lines, all described hereinbelow. In a specific embodiment of the invention illustrated in the drawings, the'plumbing assembly is' adapted for connection to a bathtub and shower G, toilet H and lavatory J in the bathroom D, and to a sink K and clothes washer M in the laundry room E. The toilet or Water closet H is of the wall hung type, so as to leave a clear floor space therebelow, as most clearly shown in FIG. 5.

The plumbing assembly includes a supporting frame or structure 20 for the severaldrain or waste lines, vent lines, and water lines. This frame structure includes opposed sets of end vertical frame members 21 and intermediate vertical frame members 22. The

vertical frame members

21,22 of each set are secured in spaced relation to one another, as by welding, to an upper horizontal or longitudinal member 23 and to a lower base horizontal member 24, thereby providing oPPO ed frame sections. Upper cross members 25 are welded, or otherwise suitably secured, to the opposed upper horizontal members 23 and are spaced from one another a distance corresponding to the distance between the vertical studs 16 of each wall set. The cross members 25 project horizontally in opposite directions beyond the horizontal members 23 and have vertical flanges 26 adapted to bear against the vertical surfaces 27 of the studs 16. The distance between the upper horizontal members 23 is preferably such that they will lie closely adjacent to the inner vertical surfaces 28 of the opposed studs 16, the projection of the cross members beyond the horizontal memb'er's 23 being suflicient to substantially overlap the studs, the flanges 26 of the cross members having suitable holes therein through which nails 29' may be inserted to be driven into the studs. The distance between the lower horizontal base members 24 is also preferably such that they will fit between and be disposed closely adjacent to the spaced wood plates 17 resting'upon the sub-floor 11 of the building or structure.

7 The drain and vent lines, as Well as hot and cold water lines, are carried by the frame 20 of the plumbing assembly: As shown, a main drain line 30 is disposed above and along the lower portion of the frame between the opposed frame sections formed by the

vertical members

21, 22, this main drain line inclining in a downward direction from the location of the lavatory J and washer M to the exterior wall F. Starting at the location of the lavatory and automatic washer, the drain lines include a vertical washer drain pipe 31, the upper end of which ex tends into a generally rectangularly' shaped shallow drip pan 32-, the latter being suitably secured to the pipe, as by soldering. Spaced apart hot and

cold water nipples

33, 34 also project through the bottom of the drip pan 32, and have respective hot and cold water faucets35 36 secured thereto for connection to the hot and

cold water lines

37, 38 of the automatic washer M, which are adapted to extend through an appropriate hole or opening 39 in the wall B on its=laundr y room side. A suitable drain hose 40 extends from the-washer and may be in serted into the vertical'washer drainpipe-31'.

Also extending upwardly through the" drip pan 32 is a vertical vent pipe 41 dispose'd'betweenthe" hot and cold water nipples 33, 34'a'ndso'ldered'in leakproof relation to the bottom of the drip pan. The drip pan itself hasa width corresponding to the horizontal distance between the upper longitudinal frame members 23 and'is; welded, orothe'rwise suitably secured, thereto,.to hold such frame members in appropriate spaced relation and to provide a cross brace or' interconnection therebetween. The vertical vent pipe 41' has its lower end connected to a drain, T47, the lower end of which is, in turn, appropriately;

connected to another'T42'se cured to an elbow secured to an inclined drain linefs'ection 44 running above and; adjacent to the lower horizontal frame members24. The

lower end of the washer drain pipe 31 is connected to a U-shaped' trap 45 attached to an elbow 46' securedto the T connection 42.

An' arm' 48, 48a of the drain T47 extends upwardly andoutwardly toward the bathroom side of the walliB and projects through and is secured to a vertical plate 49 fastened by screws, bolts, or'the like, to a perforated carrier strip 50 that can extend across the outwardly facing;

surfaces 51 of the vertical stud's1'6, to which the strip is adapted to be suitably attached, as by inserting nails through one or a plurality of'itsperforations 52 and .driv ing them into the studs 16. This vertical plate also" has; horizontally disposed hot and cold"

water nipples

53, 54 extending therethrough and suitably attached thereto, the inner ends of the nipples being adapted for attachment to. hot andcold'water'lines' and the'outerends 10f the'nipples being adapted for connection to pipping, described hereinbelow, and running to the lavatory I. The hot and cold water nipples 53, 54' and the leg 48 of'the drain T47 project outwardly or forwardly from the plate 4910a sufiicient extentas to be" disposed outwardly of the finished wall surface of' the bathroom D, so that the lavatory I can be readily and appropriately attached thereto. The plate 49 is disposed at the desired vertical height, and the spacing between the hot and

cold water nipples

53, 54 and the location of th'e'leg 48 of the drain T are also predetermined and accurately located, bo'tli vertically and horizontally.

The lower end of the drain line section 4 4 isc'onnect'ed, to a T-Y body 60, the opposed end of the T-Y body being connected to" another inclined main line drairr pipe section 61, which is, in turn, secured" to a, T Y fitting 62, the end of whichis adapted to be secured to another drain line section 63 extending'outwardly through the outer wall F of the building for appropriate connection' to a sewer line (not shown). The upper leg 64 of the T Y body is connected to the lower end of 'a' vertical toilet vent pipe 65,- the upper end of which is connected to the depending leg portion 66 of a T vent fitting 67.'

One arm 68 of this fittingis connected to a horizontal vent section 69 attached to an elbow 70 connected to the vertical vent pipe 41 for the lavatory I and automatic Washer M. The other arm 71 of the T vent fitting 6'1 is connected to a horizontal vent section 72 extending" to the T fitting 73 to which the mainvent ipe 74'is connected that extends upwardly from the fitting for appropriate extension through the roof of the dwelling; The lower portionof the T fitting 73 is connected to another vent pipe section 75 that depends therefrom and which is secured to a T fitting 76 having a horizontal leg portion 77 adapted to project toward the laundry room E, this leg portion 77 being connected to a drain nipple 78 extending through a vertical plate 79, this plate being suitably sec'ur'ed to a perforated carrier strip 80 that is adapted to overlap vertical studs 16 of the wall through which nails (not shown) can be inserted through its end perforations 81 and driven into the studs. This plate 79 also carries spaced apart horizontal hot and

cold water nipples

82, 83 adapted to be connected to hot and cold water lines, described hereinbelow, the

nipples

82, 83 and the drain nipple 78 projecting outwardly from the plate to a predetermined extent so as to be in an appropriate location relative to the finished wall of the laundry room E for connection to the laundry room sink K, as described hereiubelow. The plate 79, carrier strip 81?, drain member 78, and hot and

cold water connections

82, 83 can be the same as described above with respect to the bathroom lavatory J.

The lower end of the T -shaped fitting 76 is connected through a short nipple 85 and a wet vent fitting 8& to an upper inclined arm 87 of the T-Y fitting 62, which arm is adapted to be connected to the bathtub and shower device G disposed in the bathroom, The inclined upwardly extending arm 87 of the T-Y fitting has a sanitary connection 88 intersecting it at an angle, as at a 45 degree angle, extending downwardly toward the inclined arm 87, and also downwardly toward the main body portion of the T-Y fitting 62. A horizontal portion 89 extends outwardly from the sanitary arm 88 and is adapted to be connected to an elbow 90, which is, in turn, connected to a generally U-shaped waste and overflow trap 91 of the bathtub. The drain water from the bathtub will flow through the sanitary T connection 88 into the T-Y fitting 62 and then into the main drain line 36.

The leg 92 of the TY body 60 extends upwardly from the main drain line portion of the latter and has an arm 93 projecting forwardly therefrom between the intermediate vertical frame members 22, the inner end of this arm having a straight internal thread 94. Through appropriate connections, such arm is appropriately related to the toilet bowl H so that the effluent therefrom fiows into the closet bend or elbow 92 and from the TY body 60 into the main drain line 30.

The toilet bowl H is adapted to be hung from the wall B, and to accomplish this purpose, the plumbing assembly includes a toilet carrier 95. This carrier includes vertically spaced upper and lower horizontal channels 9-5, 97 having vertical fiange portions 98 extending along the inner sides of the intermediate vertical frame members 22 to which they are suitably secured, as by welding. Such legs or flanges 98 of the channels extend along the wall studs 16 on both sides of the wall structure and may engage the latter. The end portions 99 of the legs of the channels at one end may be bent outwardly so as to provide oppositely directed wings overlapping the opposed studs l, these wings having suitable holes or perforations therethrough through which nails 1% can be inserted and driven into the studs. In a similar manner, the other end portions of the channels will have wings 101 bent outwardly from the legs 98 to overlap the next set of studs 16, these wings having perforations through which nails 1tl2 can be inserted and driven into the opposed studs on opposite sides of the wall. The web portion 103 at this end of the lower channel can be bent upwardly to provide a vertical plate through which a lclamp bolt 184 can extend, this bolt being tightened, by turning suitable nuts 105 threaded on it, against the vent pipe 65 to hold the latter securely in position. The central portion of a leg 98 of the lower channel 97 is cut away to provide an opening for passage of the outwardly projecting arm 93 of the closet bend or elbow 92.

The depending flanges 98 of the

channels

96, 97 have threaded nuts or bosses 106 secured thereto, the lower channel 97 having a threaded boss at its forward leg 98 only at one side of the arm 93, in view of the fact that the closet bend or elbow 92 passes therebehind. Studs 107 are threadedly mounted in the bosses 106 and project forwardly of the plumbing assembly frame 20 to a suificient extent as to project beyond the finished wall 110 of the bathroom D, the threaded bosses 106 and studs 197 being appropriately located so as to conform to companion aligned holes in the rear plate portion 108 of the water closet or toilet. As described hereinbelow, such rear plate portion is mounted over the studs 107 and suitable nuts 109 are threaded on the studs and tightened against the plate 1G8 to cause the latter to bear against the finished wall 110 of the bathroom.

The toilet load is transmitted through the wall 110 directly to the

channels

96, 97, there being an intermediate filler block 111 extending across the outer surfaces of the upper and lower channels of the toilet carrier, which block may be made of Wood, this filler block bearing against the outer legs 98 of the channels and with its outer surface being disposed substantially in alignment with the outer surfaces of the wall studs 16 at its bathroom side.

The vertical vent pipe section 75 supports the hot and cold water lines and valve mechanisms for the bathtub and shower. As shown most clearly in FIGS. 1, 7, 12 and 13, a supporting member or body 115 surrounds and is suitably secured to the vent pipe section 75, having op posed arms 116 extending therefrom, to the outer portions of which are secured

vertical nipples

117, 118 for hot and cold water. The upper ends of these nipples are connected to hot and

cold water valves

119, 128, the outlets from these valves being suitably connected to a diverter valve 121. An upper line 122 runs from the upper end of the diverter valve to be connected to the shower 123, and a lower line 124 extends downwardly from the diverter valve and is connected to an elbow 125 adapted to be attached to the outlet fitting 125a which discharges into the bathtub therebelow.

The plumbing assembly also includes a hot and cold water distribution system. A cold water manifold 126 is clamped, or otherwise suitably secured, to a bracket 127 extending between a pair of vertical end frame members 21 adjacent to the outer wall F of the building, the manifold having a fitting 128 extending therefrom for connection to a cold water line 129. A fitting 136* projects from the manifold or cold water header 126 for connection to a pipe 131 running to a hot water heater (not shown). At the opposite end of the frame 20 is another manifold or header 132, which is clamped, or otherwise suitably secured, to a bracket 133 extending between and attached to the opposite vertical end frame members 21, this manifold having a fitting 134 extending therefrom for connection to a hot water line 135 extending from the hot water heater.

A cold water line 136 runs from the cold water manlfold 126 to the cold water nipple 118 for the bathtub. Another cold water line 137 extends within the frame to the cold water nipple 83 extending through the vertical supporting plate 79. A third cold water line 138 extends from the manifold 126 to the cold water nipple 34 for the clothes washer that projects through the bottom of the drip pan 32; whereas, a fourth cold water line 1339 extends from the manifold 126 to the cold Water nipple 54 extending through the supporting plate 49 for the lavatory J. A fifth cold water line 149 extends from the manifold 126 to an elbow fitting 141 secured to a bracket 142 that is to be attachable to a vertical stud 16, this fitting having a suitable nipple 143 extending therefrom to supply cold water to the water closet or toilet H.

A hot water line 144 extends from the hot water manifold 132 to the hot water nipple 117 for the tub and shower G, a second hot water line 145 extending from the manifold to the nipple 82 of the laundry sink K. A third hot water line 146 extends from the hot water manifold 132 to the nipple 33 of the washer M; whereas, the fourth hot water line 147 extends from the manifold to the nipple 53 supported by the vertical plate 49 for the lavatory I. All of the hot water lines are preferably located between the

frame members

21, 22 of the plumbing assembly to be enclosed and protected thereby.

The plumbing assembly A is prefabricated with precision within an appropriate manufacturing plant or factory. It includes the frame structure 20, the drain and vent lines and fittings, the water lines and fittings, and all of the other parts described above connected to the frame structure. All of the connections for attachment to the several plumbing appliances and fixtures have been predetermined and are located at selected positions both vertically and horizontally so as to be readily attached to the companion appliance. The drain and vent members and the water lines are made of a suitable material or materials, as, for example, copper, the joints between the several members being substantially entirely slip joints and soldered to one another to provide strong, sturdy and leakproof connections while occupying a minimum of space, there being smooth flow lines between the several parts. If desired, the several drain and vent pipe elements can be made of an appropriate synthetic resin, with the slip joints therebetween, the parts being attached in a strong, sturdy and leakproof relation to one another through use of a suitable glue, such as an epoxy resin. The making of the parts of copper, or a suitable synthetic resin, makes it unnecessary to thread substantially all of the parts and to provide extraneous seals between the several members, which need merely be soldered or adhesively attached to one another, as in the manner described above. The interconnected parts of the plumbing assembly serve to support one another, and they also serve to provide rigidity to the frame structure 21 The prefabricated plumbing assembly A (which does not include the cold water inlet line 129 or the

lines

131, 135 running to and from the hot water heater, nor the upper vent pipe 74) is delivered to the building site as a package and is mounted within the dual wall structure B between the opposed aligned sets of vertical studs 16. The lower horizontal members 24 may rest upon the subfioor 11 between the opposed plate members 17, the cross members 25 then being nailed to the studs 16, the distance between the cross members and the distance between the studs being predetermined so that the parts fit snugly against one another. Similarly, the

wings

99, 101 of the channel carrier structure are secured to the studs 16, as well as the

perforated strips

50, 80 for the lavatory and sink

plates

49, 79, these strips being attached to the outwardly facing portions of the studs 16. Once secured in place, the main vent pipe 74 is connected to the T73 for upward projection to the desired extent, as through the roof of the dwelling unit, the cold and hot water lines 131, to and from the heater being appropriately connected to the cold and

hot water manifolds

126, 132 and the main cold water line 129 attached to the cold water manifold. The bracket 142 for the toilet water elbow 141 can be secured to an adjacent stud 16 by driving a nail through the bracket andinto the stud.

It is a comparatively simple matter to connect the clothes washer M to the plumbing assembly. it is only necessary to attach the hot and

cold water lines

37, 33 to the respective hot and

cold water valves

35, 36 projecting upwardly from the shallow drip pan 32. The drain hose 40 from the washer need merely be inserted into the vertical washer drain pipe 31. All of the

lines

37, 38, 49, of course, will extend through the opening 39 provided in the finished wall of the partition B.

The lavatory I can be connected to the plumbing assembly A in a rapid and easy manner. The lavatory is supported from the wall structure B in any suitable manner, the drain pipe 151 from the lavatory being connected to a U-shaped trap 152 communicating with a trap elbow 153 that extends into the nipple portion 48a projecting through and extending on opposite sides of the vertical supporting plate 49, this nipple portion 48a being disposed around the forwardly projecting leg portion 48 of the drain T47 and being attached thereto in leakproof relation by solder, or the like.

Leakage between the trap elbow 153 and the nipple 8 48a is prevented by a nut 154 disposed around the elbow, which is threaded on the end of the nipple 48a projecting through the finished wall 11% of the bathroom, the nut compressing a suitable gasket seal ring 155 against the end of the nipple 48a. 7 I

The hot and

cold water nipples

53, 54 for the lavatory have their threaded ends projecting the appropriate distance outwardly of the finished wall 119 of the bathroom and are connected to their respective elbows 156, the upper ends of which are connected to the hot and cold water lines 157 running upwardly to the hot and cold water valves 15%, 159 of the lavatory. Water from these valves may discharge into a mixing chamber, in a known manner, from where the water can flow through a spout 160 into the lavatory bowl.

When the finished bathroom wall 11! has been provided, the carrier studs 107 project outwardly through the latter to the required extent. Since the precise location of the outer surface of the bathroom wall 114) is not previously known with accuracy, an adjustable connection constitutes part of the plumbing assembly to insure the appropriate leakproof assembly of the toilet bowl H to the plumbing assembly A, with assurance that the toilet bowl will be clamped flush against the finished wall. As shown most clearly in FIGS. 5 and 6, the closet bend or elbow 92 of the toilet drain has the straight internal thread 94-, described above. An adapter 161? is secured to this elbow in leakproof relation. As shown, it includes an inner portion 161 having an external thread 162 adapted to appropriately mesh with the internal thread 94 of the elbow, and also having a forward outwardly directed flange 163. The inner surface of this fiange engages and is suitably secured, as by soldering, to an outer portion 164 which has a skirt 165 adapted to encompass the outer portion 93 of the elbow in spaced relation thereto to provide an annular space 165a adapted to contain bowl wax sealing material 166, this material also being disposed between the end of the elbow 93 and an inwardly directed flange 167 of the outer portion of the adapter. The adapter member 164 has a skirt 168 projecting forwardly beyond the end of the inner portion flange 163, the skirt portion being provided with a plurality of slots 169 adapted to receive a suitable wrench (not shown) for turning the entire adapter 160 and threading it appropriately into the elbow 93 so that the outer surface of the flange 163 of the inner portion of the adapter is flush with the outer surface of the finished wall 11%. The inward threading of the adapter 160 within the elbow part 93 will compress the bowl wax sealing material 166 between the adapter 169 and elbow 93 and provide a leakproof seal for the threaded

connections

94, 162 between the adapter and elbow.

Following the adjustment of the adapter 16% so that its outer surface is flush with the outer surface of the wall 110, the toilet bowl H is mounted on the studs 107, a suitable bowl wax sealing material 17% being disposed in the circumferential groove 1713 opening outwardly through the rear of the bowl and disposed around the drain opening 171 of the toilet or water closet H. The studs 1%? project through the companion holes in the rear plate 108 of the toilet, whereupon nuts 139 are disposed on the studs and are tightened to firmly clamp the plate of the bowl against the wall 110. During such clamping action, the outer skirt 168 of the adapter extends into the toilet groove 170 and will result in the firm compression of the seal material 170a within the groove and against the adapter 160, to insure against leakage between the toilet bowl H and adapter. The slots 169 in the adapter skirt 168 provide regions for excess bowl sealing material to move. The toilet itself usually has additional relief regions communicating with the groove 170 into which excess seal material 'can be displaced,

' without interfering with the flush and intimate contact An appreciate connection is then made from the cold water nipple 143, through suitable fittings (not shown), to the toilet bowl.

Any vertical load imposed upon the toilet bowl H will be carried by the studs 107, which are firmly secured to the

channels

96, 97 of the toilet carrier 95, which is, in turn, securely fastened to the studs 16 of the wall and to the assembly frame 21). Inward compressive loads imposed by the toilet on the wall 110 are transmitted directly through the filler block 111 to the channels, and from the channels to the vertical studs 16 of the wall. The entire construction is strong and sturdy, and is yet relatively inexpensive.

The sink K in the laundry room E is also easily connected to the plumbing assembly A. This sink is supported in a known manner, its drain pipe 175 being connected to a U-shaped trap 176, which is, in turn, connected to a trap L177 connected to the nipple 78 mounted in the vertical support plate 79 in substantially the same manner as described above in setting forth the assembly of the lavatory J to the dra'm line. In a similar manner, the hot and

cold water nipples

82, 83 are connected through respective elbows 178 to the hot and cold water pipes 179 of the sink, which are suitably secured to the hot and cold

water sink valves

192, 193 that discharge into a mixing chamber 180 connected to a sWing spout 181 disposed over the sink.

The bathtub G is located in position in the bathroom D, as adjacent to the finished wall 111) and outer wall 15, the hot and

cold water valves

119, 125 and diverter valve 121 projecting the appropriate distance forwardly of the finished bathroom wall 110, the desired horizontal and vertical positions of the valves being predetermined at the factory in assembling the several valves and fittings to the vent pipe section 75 through use of the valve sup port 115. The outlet 182 at the bottom of the bathtub communicates with an elbow connection 183 attached to the horizontal arm portion of the waste and overflow trap 91, an overflow pipe 184, communicating with the upper overflow opening 185 of the bathtub, extending into a vertical arm of the waste and overflow trap 91. The water and other material will flow from the overflow trap 91 through the elbow 90 and nipple 89 into the sanitary connection 88, which is disposed at a 45-degree angle and in a downward direction into the main body of the T-Y fitting 62.

The bathtub spout 126 is suitably connected to the elbow 125 connected by the pipe 124 to one end of the diverter valve 121, the arm 123 of the shower head being connected to the L-shaped length of pipe 122 extending upwardly from the diverter valve. The hot and cold water valve controls project forwardly from the bathroom wall 110, which is also true of the control arm of the diverter valve.

The prefabricated plumbing assembly A is economical to manufacture and can be shipped as a package or unit to the building site. When mounted within the double wall structure B of the building, it greatly strengthens the latter, there being more than ample strength to enable a wall hung toilet H to be appropriately supported by the studs 16 through the agency of the

channel carrier members

96, 97. The frame 20 of the plumbing assembly acts as a carrier for the plumbing system during transportation and storage, as well as an internal brace or core for the double wall B. It adds strength to the double wall, and provides additional strength for supporting the several plumbing fixtures and fittings from the wall structure. The entire plumbing assembly A is such that it definitely locates the drain and water outlets for the plumbing fixtures that are to be associated with the plumbing assembly, following its installation in the double wall structure.

The drip pan 32 for the clothes washer M not only appropriately locates the hot and

cold water valves

35, 36 and the drain pipe 31 within the wall B and with respect to the washer M, but the drip pan assists in bracing the assembly frame 20, and definitely locates the several pipes for the washer in both horizontal and vertical directions.

The plate and perforated strip assembly for the lavatory J and the laundry sink K also definitely locate the drains and hot and cold water connections both vertically and horizontally, so that it is a relatively simple and easy manner to connect the sink and lavatory drains thereto, as well as to effect a connection between the hot and cold water nipples and the hot and cold water valves of the fixtures.

The drain connections from the toilet H are such that they provide relief to the latter at its lowest elevation. The T-Y body 60 connected to the toilet enables the toilet to have a longer vertical siphon leg 189, while, at the same time, relieving siphon action by virtue of the fact that the toilet vent pipe 65 is effective at substantially the lowest point of the T-Y body. The T-Y fitting 60 functions both as a siphon and also as a vent for the main drain line 30. Thus, the entire drain siphoning and venting function is accomplished in a simple and highly eifective manner.

The toilet H is supported from the wall by a structure which is rigid, sturdy and strong. The toilet load is carried through the threaded studs 1117 and the carrier to the vertical wall studs 16, the filler 111 efiecting a direct transmission of inward loads on the toilet to the carrier and then to the wall studs. The toilet is easy to install, it merely being necessary to appropriately adjust the adapter within the drain elbow 93, the nuts 109 behrg tightened to cause the outwardly directed skirt 16a; of the adapter to move within the toilet groove and compress the sealing material 170a therewithin. This insures a proper seal of the toilet bowl H to the drain pipe, the outer seal 170a preventing leakage between the bowl H and the adapter 160 and the inner seal 166 preventing leakage through the threaded

connection

162, 94 between the adapter and the drain pipe elbow portion 93.

The T-Y sanitary connection 62 between the bathtub G and the main drain line 39 allows the bathtub to be connected to the main drain line with the latter disposed fully above the floor. It is evident from FIGS. 1 and 14 that the inclined main drain line 30 is fully above the subfloor 11. An inspection of FIG. 7 discloses that the main drain line 30 is below the bottom of the bathtub G, there being a vertical siphon leg to pull water out of the bathtub, except for the water which will remain in the trap 91. The direction of flow from the sink K, and also from the bathtub G, into the upper inclined portion 87 of the TY fitting 62 insures its continued outward and downward flow through the main drain line 30 toward the exterior wall C of the building structure, and away from the region of the bathtub, thereby preventing any water in the main drain 30 from backing up into the bathtub.

The supporting of the hot and

cold water nipples

117, 118 for the bathtub and shower from the vent pipe 75 and the attaching of the nipples to the arms 116 of the support 115 enables the hot and

cold water vaives

119, 120 and the diverter valve 121 to be located on proper centers and heights, and also insures that such valves are disposed at their minimum extents of projection from the finished wall 11s of the bathroom, the entire assembly being strong and rigid, as well as being compact.

The entire plumbing assembly A comprises substantially fewer parts than was heretofore necessary for providing connections to the same number of appliances in a dwelling unit, or other structure, the parts being firmly and rigidly attached to each other in leakproof relation, insuring proper draining, venting and siphoning action. The entire plumbing assembly can be manufactured at a much lesser cost, it enables the overall thickness of the wall B in which it is installed to be held at a minimum, and actually produces a stronger wall structure, rather than 11 weakening the wall structure, as previously occurred. Not only are large economies in manufacture and installation in the wall efiected, but the assembly greatly facilitates the mounting of plumbing fixtures in the building and their appropriate connection to it, thereby effecting considerable savings in labor costs.
