Purpose: For use in above ground drainage systems to prevent release of foul air and to admit air under conditions of reduced pressure arising from water flow in the discharge pipes and stack. No need to penetrate the roof structure and no need for additional venting pipes.
Fitting Tips: Solvent welded in a vertical position to the top of the internal stack above flood level of the highest appliance allowing the soil stack to be terminated internally. The valve incorporates a socket for solvent welding to 110mm UPVC pipe. To avoid dislodging or damaging rubber seals, always ensure pipe ends are chamfered and lubricated. For Pushfit joints, allow 10mm gap between pipe and end of socket for expansion purposes. For solvent joints, apply a liberal coat of Hunter Solvent Cement to both surfaces and twist together to form a tight connection. Wipe off any excess cement.
