The cause of the tube explosion caused by the vacuum tube of the solar hot water engineering system:

Pressure is too large - because the pump is not properly selected, head is too high, or the use of tap water pipe network pressure, leading to excessive pressure on the glass tube, leading to explosive tube. In addition, the one-way valve of the water inlet pipe is closed, especially the water tank is lower than the collector, resulting in the system negative pressure phenomenon, it is also very easy to fry the tube.

Solution: select the appropriate pump or in the inlet to install a pressure reducing valve, so that constant pressure.
