The height difference between the solar energy tank and the pressure tank is approximately 15 meters. The pressure gauge shows 0.2 MPa and water can be supplied normally. 0.2MPa can send water up to a height of 20.4 meters.

You can't get in the water in this situation.
When there is no water pressure, water cannot be supplied to the solar water tank. If there is no check valve installed on your solar pipeline, water supply at this time may cause water leakage. into the solar water tank to leak. The remaining water returns to the water line. It is therefore preferable not to enter the water when there is no pressure.n of water.
