Waterco Main drain with hydrostatic valve and stem

Waterco Main Drains

Waterco Main Drains are manufactured using the highest quality impact-resistant thermoplastic (ABS plastic). The main Drain incorporates a Hydrostatic valve. This valve will safeguard and stop your pool from lifting out of the ground or “popping” when the water level is low or water accumulates under the pool shell. The stem collects groundwater at a greater depth and allows the hydrostatic valve to release it before it can build up to a level that may damage your pool.

Waterco Main Drains are available in white and grey.
