Why replace a hydrostatic valve?

A working hydrostatic valve helps stabilise the pressure beneath and inside the pool. If the valve fails, pressure can contribute to pool walls deforming or splitting, floors lifting and cracking, or the pool moving out of the ground.

Replacement guidance

Hydrostatic valves commonly last around 5 to 6 years. Pool chemicals can harden or crack the valve seal and O-ring, while calcium build-up or spring failure can cause the valve to seize open.
