A foam housing surrounds first and second water conduits and a drain conduit with the ends of the conduits projecting outwardly from opposite end walls of the housing. A tee-fitting is interposed in each of the conduits and is connected to a connector pipe projecting exteriorly of a front wall of a housing for connection to a sink hot and cold water lines and a sink drain line. Upper ends of the first and second conduits are closed to form air cushions. The upper end of the drain pipe is removably closed by a cap. The lower ends of the conduits project exteriorly of the lower end wall of the housing and are insertable through holes drilled in the base stud of a frame wall for connection to a building water supply pipes and drain pipe and in supporting the housing in a frame stud wall.
