Prefab Wablock Y-piece with check valve

Description

The check valve that keeps working. The outgoing leg incorporates a membrane that opens readily in the direction of passage, preventing dirt accumulation at the valve. In the opposite flow direction from the municipal drains system, the valve is closed extra firmly which eliminates leakage. The opening is aligned with the water flow so that any air flow in the opposite direction is blocked. Free-fall inspection and monitoring capability. The valve is available as a separate product or integrated in a Wavin domestic outlet. KIWA-certified material. Note! The check valve is preferably placed at the property boundary with the municipal drains system. However, if customisation is required and another location is more suitable, the specialists from our Prefab department will be happy to advise you on this.
