Mcalpine 1-1/4″ Multifit Anti Syphon Bottle Trap 75mm Seal A10V

£7.90 inc VAT

By drawing air through the Valve, the Silentrap neutralises syphonic pressure before it reaches the seal of the Trap and therefore provides the equivalent of a ventilated system without the installation of costly and unsightly ventilation pipes. The Silentrap has been most rigorously tested and will not unseal, even under the most abnormal conditions and should continue to be effective irrespective of the distance between the appliance and the soil pipeWhenever syphonic conditions develop, the negative pressure causes the Valve to rise, allowing air to be drawn into the discharge pipe. The pressure is thereby neutralised before it can have any effect on the water seal within the Trap. On cessation of the syphonic action, the Valve closes, making the Silentrap air and watertight
