Installing a solar pool heating system not only extends your swimming season, but can also add value to your home. However, if incorrectly installed the integrity of your new asset can be jeopardised, especially during system drain down.
Properly installed, a solar pool heating system should freely drain back to the pool without subjecting the solar system to any negative pressure each and every time the solar pump is switched off. This drain down results in outgoing water being replaced with incoming air; any restriction to this incoming air will create a vacuum within the solar system that has the potential to irreparably damage systems components.
It may come as a surprise to some people as to the degree of damage this vacuum may present, as you can see in the image above, the negative pressure can be so intense that it will crush a PVC pressure pipe. The Boss VacRel® Vacuum Relief Valve has been specifically engineered to open at an extremely low negative pressure (-6.8 mbar) to allow the air to enter the system unimpeded thus protecting the systems components from crushing, thus eliminating internal splits and leaks.
