Abstract
A single piece adapter is provided for use in sealing a water closet to sewer pipes of different diameters.
Description
- The field of the invention is connections between plumbing fixtures and drainage piping and in particularly the invention relates to sealing water closets to an associated drain pipe.
- Water closets are commonly connected to a three inch or a four inch PVC plastic drain pipe using a standardized PVC plastic closet flange. The downwardly extending annulus or hub of the plastic closet flange is dimensioned to accept a three inch plastic drain pipe in its interior and a four inch plastic drain pipe on its exterior. In both instances the plastic drain pipe is secured to the closet flange hub by a commercially available solvent cement.
- It has long been recognized that the connection between the water closet and the drain pipe is the most troublesome connection in the plumbing system. A leaking connection will allow sewer gas to enter the building and if stoppage occurs in the drain pipe, sewage may be discharged into the cavity beneath the water closet with attendant breeding of germs. It is customary to use putty or a wax ring to seal the water closet to the closet flange or the drain pipe; however, such sealing arrangements are often ineffective. There have been many attempts to improve the sealing between the water closet and the drain pipe as evidenced by a U.S. Pat. No. 2,976,543 issued Mar. 28, 1961 to H. J. Turner et al. for a Gasket Ferrule, a U.S. Pat. No. 5,185,890 issued Feb. 16, 1993 to G. W. Dismore et al. for a Toilet Bowl Sealing Assembly, a U.S. Pat. No. 5,291,619 issued Mar. 8, 1994 to C. R. Adoijan for a Water Closet Sealing Adapter, a U.S. Pat. No. 5,937,450 issued Aug. 17, 1999 to B. Jones for a Method and Device for Attaching Fittings to Receptacle and a U.S. Pat. No. 6,070,910 issued Jun. 6, 2000 to B. E. Hodges for a Push-In Closet Flange. These and other proposed solutions to the water closet sealing problem have not been found satisfactory for a number of reasons. Some require too many parts, some are too costly and some do not accommodate both three and four inch sewer pipe.
- An inexpensive one piece seal adapter is provided for sealing a water closet connected by a closet flange to either a three inch drain pipe or a four inch drain pipe. The seal adapter is made of an elastic plastic and includes a tubular portion with a pair of axially spaced annular flanges extending radially outward from the tubular portion a sufficient distance to make sealing contact with the interior of either a three inch sewer pipe or with the interior of the tubular part of the closet flange when a four inch sewer pipe is connected thereto. The seal adapter includes a radially outward extending annulus at the upper end of the tubular portion and preferably has a washer shaped seal adhesively secured at its underside to the upper surface of the annulus.
- The invention is illustrated in the accompanying drawings, in which:
-
FIG. 1 is a section showing the seal adapter between a water closet and a three inch sewer pipe; -
FIG. 2 is a section showing the seal adapter between a water closet and four inch sewer pipe; -
FIG. 3 is a section of the seal adapter, and -
FIG. 4 is a section of the seal adapter installed between a water closet and a four inch sewer pipe including an additional sealing washer between the adapter and the top of the closet flange. - As illustrated in
FIG. 1 , a water closet 11 is secured to afloor 12 by a somewhatstandard closet flange 13 having acollar 14 connected to thebase 15 of the water closet 11 by bolts and nuts, such as thebolt 16 and thenut 17 shown inFIG. 4 . Thecollar 14 is secured to thefloor 12 byscrews 18. Thecloset flange 13 includes atubular part 19 which extends downwardly through an opening 21 in thefloor 12. The interior diameter of thetubular part 19 is approximately the same as the exterior diameter of a threeinch sewer pipe 22 and, as shown inFIGS. 2 and 4 , the exterior diameter of thetubular part 19 is substantially the same as the four inch interior diameter of a fourinch sewer pipe 23. Thecloset flange 13 and thesewer pipes annular protuberance 27 which is in general alignment with the floor opening 21 and with thetubular part 19 of thecloset flange 13. A downwardly facingflat surface 28 surrounds theprotuberance 27 in the cavity on the underside of thebase 15 of the water closet 11. - A one piece elastic
plastic seal adapter 31 forms a sealing connection against gas and sewage leakage between theunderside surface 28 of the water closet 11 and thecloset flange 13 when either one of thesewer pipes closet flange 13. Theseal adapter 31 includes a flathorizontal annulus 32 which, as shown inFIG. 3 , has parallel upper andlower surfaces 33, 34 in confronting or sealing relation to theunderside surface 28 of the water closet 11 and the upward facingsurface 36 of thecollar 14, respectively. As illustrated inFIGS. 1 and 2 theannulus 32 of theseal adapter 31 includes a foam plastic washer shapedseal 37 whose underside is adhesively secured to theannulus 32 of theadapter 31 and whose top side is adhesively secured to the downward facingsurface 28 of the water closet 11.FIG. 4 shows a second embodiment of the invention in which a second foamplastic washer 41 is adhesively bonded to the underside of theannulus 32 of theseal adapter 31. The second foamplastic washer 41 is used for non-standard water closets. - The one
piece adapter seal 31 includes atubular portion 46 which extends downwardly from the interior diameter of theannulus 32 and has an outside diameter substantially smaller than the inside diameter of thetubular part 19 of thecloset flange 13. A pair of axially spaced elastic plasticannular flange seals inch sewer pipe 22, as shown inFIG. 1 , or with the inside diameter of thetubular part 19 of thecloset flange 13, as shown inFIG. 2 , wherein a 4inch sewer pipe 23 is connected to thetubular part 19. As shown inFIG. 3 , in which anuninstalled seal adapter 31 is illustrated, the thickness of theflange seals tubular portion 46. A thin removable plastic sheet 51 placed in protective cover on the top of theseal 37 is removed prior to installation of theseal adapter 31. - The
seal adapter 31 shown inFIG. 3 is an effective one-piece seal for a water closet connection to either a 3 inch or 4 inch sewer pipe. The plumber need only be concerned about being supplied with a single component for sealing water closets to 3 or 4 inch sewer pipes, which covers most residential buildings and a large portion of commercial buildings.
