How to deal with discarded solar water heaters? Don't be too embarrassed if you collect the was

I don't know exactly what place you are talking about. Because there are several connections to the place you mentioned. 1. The connection between the water pipe and the joint. It depends on the type of pipe you use. For hot melt pipes, the connection is not good enough when hot melting, which causes water leakage for aluminum-plastic pipes. the screws are not tightened or the sealing ring is damaged. 2. The connection between the joint and the water tank pipe is often caused by the raw material tape not being properly wrapped, causing water leakage. 3. The connection between the water tank pipe and the water tank. There are two commonly used connection methods: soldering type and silicone gasket type. If it is welded, the water tank will need to be replaced. If the warranty period has expired, you will need to find an argon arc welder to remove the layer iSolante and weld it. If it is a silicone type of seal, simply replace the sealing ring. If there is no replacement in stock, you can replace the exhaust port sealing ring on the top and use it (general solar is universal). In my opinion, it is the seal ring that is most susceptible to damage.
