In pool maintenance, what is the general purpose of hydrostatic valves?

The general purpose of hydrostatic valves in pool maintenance is to control water levels. These specialized valves serve to relieve hydrostatic pressure from the water table beneath the pool when the water level drops too low, effectively preventing the pool shell from floating or shifting due to changes in groundwater pressure. When the water in the pool is at normal levels, the valve remains closed, thus retaining water and maintaining pool integrity.

In situations where the water level decreases, the hydrostatic valve opens to allow groundwater to enter the pool area, balancing the pressure and preventing potential structural issues. This ensures that the pool maintains its stability and longevity, which is crucial in areas where the water table can fluctuate significantly. Balancing water levels is vital for the overall maintenance and protection of the pool structure.
