Hot tub pool problem

Often the check valve can get stuck slightly open by a leaf or twig. Even a fraction of an inch is enough to let the water drain out.

The type and quality of check valve is important too. Some valves made for water line use are not that suitable for pools as they tend to "leak" slightly.
