Connection: ABS Solvent Weld Spigot to BS EN 1455-1. Polypipe Soil & Vent: Anti-syphon unit (automatic air admittance valve) for Ø32mm (1 1/4'') waste pipe allows air to enter branch discharge pipes, protecting water seals in traps from effects of negative pressure and preventing self-siphonage. When negative pressure is encountered, the valve will automatically open and allow air to enter the waste stack, equalising pressures and therefore preventing loss of water seals in the traps on appliances.ģ2mm valves (anti-syphon units) are for use on on branch discharge pipes. When installed, the valve is in the closed position and will prevent foul air escaping from the pipework system in normal atmospheric conditions or when positive pressure is created in the waste pipes by the discharge from appliances.
