A Strainer Over-Flow Pipe is a must have in any bar or restaurant that utilizes the 3 compartment sinks. Its purpose is to fit snugly in your sink drains acting as a plug. The long tube design with the opening at the top is meant to prevent over-flow of water when either filling up your sinks or washing your glasses. The Plastic pipes are set in rubber bushings to fit both 1" and 1-1/2" drain openings. They make ideal companions for our strainer funnels.
