McAlpine Tundish with Self-Closing Valve extension The McAlpine Pedestal Trap isDESCRIPTION: This tundish incorporates a self closing membrane that allows discharge to flow freely and then closes to form a seal. The membrane seal creates no resistance, ensuring smooth discharge flow from the PRV TRV, and is spring free, so not affected in hard water areas. When installed into a waste or soil pipe, it prevents foul odour or sewer gas from entering the building. SPECIFICATIONS: 15 22mm Inlet x 1 1 4" Outlet Temperature Rating 100C
