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.
