Through the previous article, we know how to detect whether PEX Fittings Plastic is leaking, so our next step is to determine the location of the leak. The following article will help you determine the location of the floor heating pipe leakage. Observe the pressure gauge changesUnder normal circumstances, if there is a leak in the floor heating pipe, the pressure gauge will drop in a short period of time. When it is determined that the leakage is slow, first stop the pipe from running, wait for the floor heating surface to cool down, and then close it after injecting pressure with hot water. Observe the pressure gauges on the valves on the manifold and make sure that the pressure gauge has not changed.Determine the leaking pointAs time goes by, the surface temperature gradually rises, and the temperature of the determined leaky pipeline will rise very high, and a peak will be formed at the leaking point, where the temperature of the leaking point will be much higher than the temperature of other parts of the pipeline.After the leaking point of the floor heating pipe is determined, it is necessary to make key judgments. Generally, the center of the leaking point is usually the place with the highest temperature. Based on this, the user can roughly determine the center of the leak, and then a small area of ground can be excavated. The PEX Ball Valve system is repaired.When you can't handle it by yourself, you must find a professional repairer to avoid larger water leakage problems and unnecessary trouble.
