ABSTRACT:
A plumbing concrete form accessory (10) includes a relatively large hollow displacement member (12) having a hole (18) in a wall thereof and defining a sleeve (19) about the hole for snugly fitting the outside surface of a pipe (48). A dissolving type adhesive is used to adhere the sleeve adjacent a first end (50) of the pipe and a second end (52) of the pipe is mounted to a concrete form (58) by means of a slidable flange (54) which is also adhered to the outside surface of the pipe. A spacer cuff (60) is mounted snugly about the outside surface of the pipe adjacent the second end thereof. The thusly mounted pipe supports the hollow displacement member in the concrete form while concrete (22) is poured about the pipe and the displacement member. In a preferred embodiment, a cover (14) is used to cover an open side (16) of the displacement member to allow selective access to the interior of the displacement member for coupling a fixture (36) to the first end of the pipe once the concrete has hardened.
