Description
- The present invention relates generally to accommodations for plumbing fittings. More specifically, the present invention relates to water closet fittings for use in connecting water closets to plumbing systems.
- A common method for installing water closets involves forming a channel through a concrete floor upon which a water closet is to be installed. The channel accommodates fluid connection means for connecting the water closet to a waste pipe of a plumbing system. Various methods are used for forming such channels through concrete floors. In one method, concrete is poured around either a cast-in-place channel device or a sleeve. In another method, the channel is formed after pouring the concrete floor by core drilling through the concrete floor to form the channel.
- After a channel has been provided through the concrete floor, a water closet flange is installed near an inlet end of the channel. The water closet flange is typically sealed to an inlet end of a waste pipe and secured to the concrete floor with fasteners drilled into the concrete. When secured to the concrete floor, the water closet flange provides a stabile platform for anchoring a water closet to the floor and placing the water closet in fluid communication with a waste pipe of a plumbing system.
- Before placing a water closet in fluid communication with a waste pipe, the waste pipe is typically pressurized to check for leaks in the waste pipe or associated plumbing system. To allow the waste pipe to be pressurized, the inlet end of the waste pipe is sealed off. This is typically accomplished by sealing a water closet flange equipped with a sealing means, such as a pressure cap, to the waste pipe. Alternatively, a plug may be positioned inside the waste pipe.
- Current methods for placing water closet flanges in fluid communication with waste pipes are labor intensive and/or prone to error. Water closet flanges are often installed early in a structure's construction process to allow waste pipes and/or associated plumbing systems to be pressurized and checked for leaks. Such installations and testing often occurs before any partition walls, or other notable landmarks, have been constructed inside the structure, which can make it difficult to align the water closet flange for subsequent proper orientation of a water closet on the flange. Although most water closet flanges offer some degree of flexibility for orienting water closets relative to the water closet flange, the alignment of a water closet flange dictates the general orientation of its water closet. As a result, care must be taken when installing a water closet flange to avoid an incorrect alignment, which will be costly and time-consuming to correct.
- The present invention is directed to a method for placing a water closet flange in fluid communication with a waste pipe of a plumbing system. The method includes providing a channel, and capping the channel with a water closet fitting. Concrete is poured around the channel to form a floor thereabout. An inlet end of the waste pipe is sealed to the water closet fitting. A cap portion of the water closet fitting is removed to permit fluid flow through the water closet fitting and into the waste pipe. A water closet flange is sealed to the water closet fitting.
- In another embodiment, the present invention is directed to an adaptor insert for placement inside a channel body to allow a water closet flange to be mounted relative to the channel body after pouring a concrete floor around the channel body. The adaptor insert includes a cap mountable on an end of the channel body. The cap includes a removable, pressure-resistant cap portion that, upon removal, permits fluid flow through the cap. An annular mating surface is attached to the cap and adapted to extend inside the channel body.
- In another embodiment, the present invention is directed to a water closet fitting for placement inside a channel body providing a passage through a concrete floor of a structure. The water closet fitting includes a flow path having an inlet adapted to sealably mate with a collar of a water closet flange and an outlet adapted to sealably mate with a waste pipe of a plumbing system. A cap is attached to the flow path adjacent the inlet and sized to seal off the flow path. The cap includes a removable, pressure-resistant cap portion that, upon removal, permits fluid flow from the inlet to the outlet.

In this configuration,annular mating surface 104 is adhered and sealed tofemale inlet surface 74 of riser body 60 (using suitable sealant materials). Ifconcrete floor 96 is poured higher than expected,flange 98 can be spaced fromrim 42 to account for the additional height, yet still be adhered and sealed tofemale surface 74. Oncewater closet flange 92 is sealably mated toriser body 60, a water closet (not shown) can be secured towater closet flange 92. - In an alternate embodiment,
water closet flange 92 is sealably mated to water closet fitting 30 instead ofriser body 60. In this alternate embodiment, water closet fitting 30 is sized so thatannular mating surface 104 ofwater closet flange 92 can be adhered and sealed tointerior surface 52 of water closet fitting 30. - Water closet fitting 30 and
riser body 60 are formed from any suitable material known in the art. Examples of suitable materials include plastics (such as, for example, PVC or ABS) and metals (such as, for example, cast iron or steel). In an exemplary embodiment, water closet fitting 30 andriser body 60 are both formed from plastic, and sealably mated to each other and other parts (as described in conjunction withFIGS. 8-12 ) with the assistance of solvent cement or other suitable adhesives. - As described above, the water closet fitting of the present invention provides an efficient system for placing a water closet flange in fluid communication with a waste pipe of a plumbing system. The water closet fitting allows a water closet flange to be installed after pressure testing the plumbing system. As such, the water closet flange may be installed immediately prior to installing a water closet, thereby reducing the chances of costly water closet orientation errors. In addition, the water closet fitting of the present invention allows a water closet flange to be installed without having to screw fasteners into a concrete floor.
- Although the present invention has been described with reference to preferred embodiments, workers skilled in the art will recognize that changes may be made in form and detail without departing from the spirit and scope of the invention.
