Abstract

See full text

A method of providing a drain pipe passageway through a concrete slab wherein a plastic pipe of predetermined diameter, which is greater than the underlying drain pipe, is positioned in an upright manner within a location of a concrete slab to be poured. Concrete is poured around the pipe to a desired level leaving a portion of the pipe exposed above this level, and the concrete is permitted to solidify. Thereafter the exposed portion of the pipe is cut off leaving an upper opening of the pipe flush with the upper surface of the concrete slab. The upper opening of the pipe is closed off with a plastic cap and a passageway of predetermined diameter, which is smaller than the pipe diameter, is drilled through the cap at a newly calculated position of alignment, and a plastic pipe having an outside diameter which will mate with this smaller diameter of the passageway is inserted through the cap passageway and cemented in position.
