The water tank of the solar water heater is leaking. First confirm the location of the water tank leak, then use different methods according to different parts. Water tank leaks usually occur in the following situations:
First, the connector is leaking, such as the connection between the upper water pipe and the lower water pipe. Simply tighten the gasket or replace the gasket.
Secondly, if the sewage outlet is leaking, it can be solved by replacing the sewage outlet plug or adding raw material tape (or string or cotton thread ).
Third, the riveting gap leaks. This is a problem with the water tank liner. The only solution is to replace the water tank.
Fourth, if there is a water leak at the connection with the suction pipe, simply replace the sealing ring (not the dust ring).
