Vacuum Relief Valve Pool Solar

This vacuum relief valve vacuum breaker is designed specifically for solar pool heater applications.

Vacuum relief valve pool solar. As the pump stops and the system wants to drain back the function of this valve is to open on negative pressure and allow air to enter the collectors so that the weight of the water pulling internally on system components does not. Your pool pump circulates pool water through the solar collectors. The pump is not forcing water to the roof fast enough and gravity is pulling it down faster. This vacuum break valve will release the vacuum in the solar pool heating system when the pump is turned off.

Vacuum relief valve allows collectors to drain when the system is off. See figure 1 1. It allows water to flow back to the swimming pool so it doesn t get caught in the solar collector and boil or cause unnecessary sucking in resulting in a damaged collector. It is possible to replace or relocate the vacuum relief valve or to restrict the return line back to the pool.

Solar collectors solar collectors absorb the sun s heat and transfer it to pool water. For solar pool panels with 2 i d. For solar pool panels 1 5 1 1 2 i d. Vacuum release valve 7 solar pool heater must have a vacuum release valve 7 installed on or just off the roof.

The sun heats the water and the heated water is returned to your pool. This produces a little vacuum at the top of the system and air is sucked in at the vacuum relief valve or elsewhere. This vacuum relief valve vacuum breaker is designed specifically for solar pool heater applications. 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.

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. 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.
