What should I do if the solar air heater can't get on the water?
1. Open the water supply valve of the solar air heater and find that the water tank is running. It may be because the vacuum tube of the solar air heater is damaged, or the upper and lower water pipes are leaking, and they need to be replaced to solve the problem.
2. Sometimes the solar air heater is filled with water, but it is not full for a long time. It may be because the water pressure of the solar air heater is relatively low. You can install a booster pump to solve the problem.
