Swimming Pool Leak Detection DYE Testing Cones- Quick Plugs Set of 6;

These "quick plugs" are for testing underground pool plumbing for leaks during the initial stages of dye testing. Simply put; if the pump has been off, a broken pool pipe will pull dye into the pipe indicating a break behind the wall. Under Ideal conditions it is a very effective way to determine if the plumbing is the problem. In reality, the number of returns and the size of the pipe openings are too great to precisely determine the outcome of this test. Add to it convection currents and a little wind and the idea becomes absurd. These plugs quickly solve the problem of convection currents and simplify a complex system by reducing the number of jet opening to one small 9mm hole that can be dye tested quite easily and accurately. They answer the question- is the pipe broken or not?.
