Aquaglaze recommends all swimming pool owners consider the age of their pool’s Hydrostatic valve when their swimming pool first starts to leak. It should be your first line of attack before obtaining expensive pipe pressure testing and leak detection services. In most cases, pool water leaks are caused by old worn out Hydrostatic valve. Hydrostatic valves are relatively inexpensive to replace. In fact the Hydrostatic valve, in your pool, should be replaced every five years to ensure you have a good seal and your swimming pool is not losing water. AQUAGLAZE can replace your Hydrostatic valve whether your pool is full or empty. For a free quotation or some professional advice click here
