Anonymous users2024-01-24I remember that the solar water heating pipe in my house also has two pipes, one is for water and water, and the other is for the solar water heater to overflow automatically when the water level is high! If you can send a picture of the solar water heater fertilizer tank, it will be easy to do!

One water pipe: for cold water and hot water. An overflow pipe: used to know that the tank is full.
Under normal circumstances, one of the two pipes with switches, one is the upper cold water pipe, the other is the lower hot water pipe, and the water tank is not switched. Overflow pipes.
To distinguish, what you mean should be water and water, not to be confused!
The solar water heater can go down two pipes from the roof to the two bathrooms. However, it is necessary to have hot and cold water connections for solar energy. A short section of water pipe should be connected at the cold water interface, and a check valve and a solenoid valve should be installed on this pipe (the check valve is to prevent the hot water in the solar energy from flowing back to the pipe network after the water is stopped in the community, and the solenoid valve is controlled by the central control instrument). >>>More
The cold water is municipal tap water.
