A pipe attachment device (12, 52) for attaching a pipe (16, 54) to a concrete form wall (14) includes an axially extending wall (12, 54) and a floor (24, 58) extending laterally from a first end of the axially extending wall. The floor is affixed to the concrete form and the pipe to be held in place on the form is pressed on the axially extending wall. The pipe is held thereon by the friction of a force fit. After concrete is poured into the form wall and allowed to cure, the pipe attachment device is removed with the concrete form wall while the pipe is allowed to stay embedded in the wall. A separate riser (20) is adhered to the outer surface of a standard pipe (16) to prevent it from sliding out of the concrete once the form is removed. A special pipe coupler (54) can be used with a male pipe attachment device having a built in shoulder (68) and riser (64). Intumescent cuffs (18, 56) can be used with either the standard pipe or the special pipe coupler.
