Pool Solar Panel Vacuum Relief Valve

This produces a little vacuum at the top of the system and air is sucked in at the vacuum relief valve or elsewhere.

Pool solar panel vacuum relief valve.

The vacuum relief valve allows air to enter the solar pool heating system when the pool pump is turned off and facilitate water drainage from the panels. This relieves the vacuum that would be created by falling water inside the solar panels and plumbing on the roof. By allowing air to enter the pool solar panels it aids in gravity drainage of solar. It is possible to replace or relocate the vacuum relief valve or to restrict the return line back to the pool.

This vacuum relief valve vacuum breaker is designed specifically for solar pool heater applications. The pump is not forcing water to the roof fast enough and gravity is pulling it down faster.

This vrv is typically installed using a rubber coupler hose and hose clamps.

A vacuum relief valve installed at the highest point in this solar pool heating system relieves negative air pressure from water draining from the panels. The solar diverter valve controls whether water goes up to the solar panels or goes back to the pool without entering the solar panels. This is a ball spring 5 type check valve that is typically installed at the highest point in a solar pool heating system. There is should be a tiny hole in this valve that allows water to drain back to the pool when the pump shuts off.
