How it works:
The Halgan Reflux valve is equipped with a hanging, lockable, flap valve. The flap valve ensures that the rainwater or sewage flows freely through the valve while simultaneously preventing any surges into the building.

• Designed to stop storm and sewage surges
• Protects underground rainwater storage tanks from contamination from surging stormwater (as per HB230-2006)
• Stop rodents entering through pipes
• All plastic construction
• Perfect for renovations - other reflux valves with large drops are difficult to install, the Stormfix Reflux valve offers minimal drop from inlet to outlet
