An Economical Solution to a Costly Problem

One of the most important problems facing the 21st century is water conservation. The water and sewer industry is being called upon to find new solutions to old problems and to ensure that water is treated and used efficiently.

Our No Flow In Flow dish is made to our exact requirements from a virtually indestructible material, allowing us to offer you a simple-to-install, long-lasting product that eliminates sheet flow of rainwater into the sanitary sewer system.
