Slab plumbing system
First Claim
1. A method for providing a pipe passageway through a concrete slab, the pipe passageway including a lower end thereof in fluid communication with a drain pipe beneath and extending away from the slab for draining fluid therethrough, the method comprising:
- positioning a bowl within a location of a slab to be poured and made of concrete, the bowl comprising an outer side wall, the outer side wall being generally cylindrical in shape with a hollow interior and having a height and a top opening, an inner wall, the inner wall being generally cylindrical and having a hollow interior, the inner wall having a top opening and a bottom opening and a height less than the height of the outer side wall, a bottom wall comprising a generally circular ring, the bottom wall having an outer edge contacting a lower edge of the outer side wall and an inner edge contacting a lower edge of the inner wall, the bottom wall spacing apart the outer side wall from the inner wall around a circumference of the bowl, and wherein the bottom opening of the inner wall is sized for receiving a pipe member, a coupling member positioned with a portion thereof within the bottom opening of the inner wall of the bowl, and wherein the coupling member is a hollow generally cylindrical coupling having a lower end suitable for receiving a top end of a drain pipe, a cap over the top opening of the outer side wall, the cap having a top, at least a portion of the cap above a top of the outer side wall, pouring concrete around the bowl to form a slab, including pouring the concrete at least to a level such that concrete is level with and does not extend upwardly beyond the top of the cap of the bowl, and permitting the concrete to solidify to form the slab, solidified concrete encompassing and holding the bowl in the slab.

Abstract
A plumbing system, a slab therewith and a bowl for a plumbing system have been invented, the bowl, in one aspect having an outer side wall, the outer side wall being generally cylindrical in shape with a hollow interior and having a height and a top opening, an inner wall, the inner wall being generally cylindrical and having a hollow interior, the inner wall having a top opening and a bottom opening and a height equal to or less than the height of the outer side wall, a bottom wall comprising a generally circular ring, the bottom wall having an outer edge contacting a lower edge of the outer side wall and an inner edge contacting a lower edge of the inner wall, the bottom wall spacing apart the outer side wall from the inner wall around a circumference of the bowl, wherein the bottom opening of the inner wall is sized for receiving a pipe member, a coupling member positioned with a portion thereof within the bottom opening of the inner wall of the bowl, and a cap over the bowl. Following pouring of the slab, a top of the cap or the cap is removed and a pipe is inserted into a lower opening of the bowl to provide a pipe passageway through the slab. In one aspect the pipe is angled and is rotated within the bowl to locate an upper end of the pipe at a desired orientation with respect to the bowl. Methods have also been invented for using such bowls and systems.
