All Hydrostatic valve is a necessary safety feature incorporated into the Main Drain. This valve will safeguard and stop your pool from lifting out of the ground or “popping” when the water level is low or when there is water under the pool.

Other benefits of the Water co Main Drain are:

• The longer ground water spear detects underground water at a greater depth and causes the hydrostatic valve to release it before it can build up to a level that may damage your pool.
• Flush smooth surface designed with bather comfort and safety in mind.

Water co Main Drains are manufactured using the highest quality, impact resistant thermoplastic (ABS plastic). This significant feature alone offers you protection against expensive feature damage to your concrete, fiberglass, plastic or above-ground swimming pool.
