A new flexible drain pipe makes replacing one easier than a PVC drain pipe and P-trap because it is designed for easy installation using only a pair of scissors. Fewer joints mean fewer leak points and its rubber gasket seal ensures a dry base cabinet whether it is in the kitchen or bathroom.

The Simple Drain pipe is a crushproof flexible rubber hose that screws into a water-tight fitting for the waste-water wall connection and uses a clamp with a thumbscrew to connect to the tailpipe coming from the drain.

The P-trap is formed with a loop that slides on the rubber hose and can be used for a new single or twin bowl and as a replacement. Its self-plunge mechanism eliminates future clogging so no plunger or chemicals are needed.
