What should I do if the geothermal exhaust valve leaks

Water leakage from the geothermal exhaust valve is very common. Under normal circumstances, when the heating is first delivered in winter, the geothermal pipe needs to be exhausted so that the exhaust can make the heating of the underfloor heating loop uniform. However, sometimes this exhaust valve will automatically leak water, what should I do? Let's go with the editor to see some solutions to this problem!

　　 There are many cases of water leakage in the exhaust valve. We can investigate from the outside to the inside, from simple to complex, to see where the problem is. Generally speaking, we must first check the exhaust valve. If the valve of the exhaust valve is not closed tightly enough, it may cause the exhaust valve to leak water. Then we close it again and tighten it with the tool again.

　　Secondly, the exhaust valve is leaking. Another possibility is that the air in the exhaust pipe is not exhausted, and there is a lot of air in the floor heating pipe, which will also cause the exhaust valve to leak. At this time, we can exhaust the air in stages, unscrew the valve a little bit, do not fully open, exhaust the air and screw it, after a while, exhaust again, until all the air in the pipe is exhausted, and the water is discharged into the pipe. It is drained so that the exhaust valve does not leak.

　　 The heating season in winter is over, and the heating is no longer needed in the summer. After a long time, there may be rust in the exhaust valve, which will rust the exhaust valve. In this case, when the heating is turned on, the pressure will increase and water will leak. We can loosen the exhaust valve and clean the exhaust valve port to solve this problem.

　　 If the valve plate in the exhaust valve is displaced, it may also cause water leakage. When the exhaust valve is deflating, the air pressure in the exhaust pipe will decrease and the water leakage will be smaller. If the exhaust valve is closed, the leakage will be more serious. At this time, we can tap the exhaust valve and Connect the pipe so that the valve plate returns to its original position so that there will be no water leakage.

　　If the exhaust valve is made of copper or alloy, because it has a screw port, it will take a long time to leak water from the screw. We can unscrew the exhaust valve, wrap the thread with a sealed raw material tape to increase the density, and screw it on again so that no water will leak.

　　 There is a rubber gasket at the internal connection of the exhaust valve. The rubber is easy to age. If the gasket is broken or aging, it will lose its toughness and may cause water leakage. If we replace it with a new one, it won’t leak. There are many solutions, depending on the situation.
