Plumbing Requirements
Plumb system in accordance with recommended hydraulic schematic.
2” dia. plumbing is advised to ensure maximum flow of water through the solar panels. A solar
booster pump should be added if panels are installed at a very high elevation.
It is recommended that the solar panels are mounted in a way that gravity will allow draining
whenever the filter pump is not on.
For systems with glazed panels, damage can occur from overheating if the filter pump is still
running after the solar has turned off. To enable glazed panels to automatically drain whenever
the solar turns off (even if the filter pump is still running), a 1/2” motorized Solar Drain Valve
(model HW-5B) should be plumbed from the solar feed line, through a check valve, to a zero
psi point (such as pool fill line or jet air intake).
