Pool solar panel vacuum relief valve.

The vacrel is a high performance vacuum relief valve for solar pool heating. It has been designed to allow filtered air to easily enter the system therefore eliminating internal splits or leaks due to vacuum crush of the collector absorber. This produces a little vacuum at the top of the system and air is sucked in at the vacuum relief valve or elsewhere. A valve must be installed in every solar pool heating system to allow air into the system when pool water drains out of the panels.

This vrv is typically installed using a rubber coupler hose and hose clamps. There is should be a tiny hole in this valve that allows water to drain back to the pool when the pump shuts off. This is a ball spring 5 type check valve that is typically installed at the highest point in a solar pool heating system.

It is possible to replace or relocate the vacuum relief valve or to restrict the return line back to the pool. 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. For draining solar system item total 33 24 the vacuum breaker is used with solar pool heater collectors to break the vacuum by letting air into the system and allow the solar panels to drain when the pump is turned off. The solar diverter valve controls whether water goes up to the solar panels or goes back to the pool without entering the solar panels.

By allowing air to enter the pool solar panels it aids in gravity drainage of solar. 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 pump is not forcing water to the roof fast enough and gravity is pulling it down faster. This relieves the vacuum that would be created by falling water inside the solar panels and plumbing on the roof.
