How To Determine If PEX Expansion Fittings Are Leaking

　　Since the PEX expansion fittings road system is buried underground, there are certain limitations in inspection and maintenance. Once the pipeline leaks and other problems are difficult to detect in time, then when the user uses the PEX expansion fittings road system, How can I determine if PEX expansion fittings are leaking?

　　1. Conduct a pressure test

　　A good way to judge whether the floor heating is leaking is to ask a professional company to conduct a pressure test. After the PEX expansion fittings are installed, the pressure test must be done: close the main valve, use a pressure machine to pressure the PEX expansion fittings, and wait for half an hour when the pressure is 8-10 kg. If the pressure remains the same, it means that the pipeline does not leak. If the PEX expansion fittings leak, the pressure will be difficult to maintain for a long time.

　　2. Determine the leak location of PEX expansion fittings

　　1) Observe the pressure gauge changes

　　Under normal circumstances, if the PEX expansion fittings leak, the pressure gauge will lose pressure in a short period. If it is determined to be a slow leak, the pipeline should be stopped first, and after the floor heating surface has cooled down, the pressure should be injected with hot water. Close the valves on the manifold, observe the pressure gauge, and make sure that the pressure gauge has not changed.

　　2) Determine the leaking point

　　As time goes by, the surface temperature gradually rises, and the location of the leaking pipeline will rise to a very high temperature, 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 leak point of PEX expansion fittings is determined, it must be determined. Generally, the location of the leak point is usually a place with high temperatures. Based on this, the user can roughly determine the location of the leak, and then a small area of ​​ground can be excavated. The system is repaired.

　　3) Remedy for water leakage

　　After determining the location of the leaking point, close the PEX expansion fittings water inlet, and outlet valves, and then let the remaining water out of the PEX expansion fittings. Then ask the floor heating installer to dry the floor, plan the cement layer, and connect the leaking point with a joint, such as water leakage. In severe cases, the pipe needs to be replaced. After the repair is completed, the pressure test needs to be carried out again to ensure that no water leaks, and the water flow test is carried out to prevent debris from entering the pipeline and causing a blockage. After the test, the floor was laid back.

　　Many users are very troubled by the problem of water leakage in the PEX expansion fittings system. To ensure the good operation of PEX expansion fittings in the later stage, good products and standardized installation are indispensable. Choose a floor heating company with professional PEX expansion fittings installation and suppression experience to ensure that the installed PEX expansion fittings do not leak.
