Frequently Asked Questions

What does the hydrostatic valve do?

The hydrostatic valve releases groundwater collected beneath the pool shell before pressure builds to a level that may damage the pool. It helps reduce the risk of the pool lifting or “popping” when the pool water level is low or groundwater accumulates beneath it.

What is the stem for?

The stem collects groundwater at a greater depth and allows the hydrostatic valve to release it.

What material and colours are available?

The main drain is made from impact-resistant ABS thermoplastic and is available in white and grey.
