How To Maintain PEX Cold Expansion Fittings

　　The feeling of winter is bitterly cold, and the temperature difference between the north and the south is greater. Therefore, almost every family in the north has PEX cold expansion fittings, but PEX cold expansion fittings malfunctions also follow. So what should I do if PEX cold expansion fittings are not hot? How to maintain PEX cold expansion fittings?

　　One, what should I do if PEX cold expansion fittings are not hot?

　　1. The filter of the heating pipe should be cleaned

　　What should I do if PEX cold expansion fittings are not hot? PEX cold expansion fittings suggest that you can first ask the neighbors upstairs and downstairs, if there is no problem with their PEX cold expansion fittings, and the one on your water separator The water pipe is also hot, so consider that your filter may be clogged. In the next step, we will close the main valve of the inlet and return water, and then use a wrench to remove the plug of the filter, and then flush the filter to clean it, and then install it back to its original position.

　　2. Install the circulating pump

　　Because some people live on higher floors, the water flow rate is very slow. This will also cause the PEX cold expansion fittings to not be hot. At this time, we can consider increasing the speed of the return water, and install a circulating pump on the return water pipeline. This method can make the temperature in the home much higher. (Because the water separator is usually in the bathroom, and the bathroom is relatively humid, so in the process of installing the circulating pump, ensure that the electricity is safe!)

　　2. How to maintain PEX cold expansion fittings?

　　1. Do not heat up suddenly when starting PEX cold expansion fittings

　　How do we maintain PEX cold expansion fittings during frequent use of PEX cold expansion fittings? If the temperature of the PEX cold expansion fittings system is suddenly increased when the indoor temperature is too low, without passing through a transitional temperature to adapt , The parts of the entire PEX cold expansion fittings system are easily damaged. In this case, the service life of the PEX cold expansion fittings system will also be affected, and the floor may be deformed.

　　2. Maintenance of the manifold

　　Under normal circumstances, if you do not open PEX cold expansion fittings in winter, you must pay attention to the manifold. Because of the influence of the weather, the manifold will be frozen and cracked. Therefore, when the temperature has reached below zero, be sure to blow out all the water in the manifold with an air compressor. If the water is not blown out, it will freeze in it, and expand after it freezes. The pipe is blocked.
