The drain valve is used to drain condensation from your pool heat pump in a controlled manner. By connecting a hose, the condensation can be drained away cleanly and efficiently. The valve is suitable for the Silent 5-13 (Generation 2025), Silent 5-32.1 (Generation 2026), Solid 9-7 and Waterpower series heat pumps. The outer diameter of the valve, which is inserted into the underside of the heat pump, is 21.5 mm. The outer diameter of the drain connection for the hose is 15.88 mm. The drain valve thus offers a simple and practical solution for the proper drainage of condensation.
