The McAlpine WC-F26PV is a straight flexible WC connector designed for connecting a WC pan to the soil pipe. It has a 97-107mm inlet that connects to the WC pan and a 110mm plain end outlet that connects to the soil pipe. The connector is made of flexible PVC material that allows for easy installation and adjustment. In addition, the WC-F26PV also features a 1.25" universal vent boss that allows for connection to a soil vent pipe or an air admittance valve. The vent boss provides ventilation to the drainage system, preventing the buildup of pressure and unpleasant odors.
