McAlpine WC-F23RV Flexible Pan Connector with 1¼” Vent Boss

Features

The McAlpine WC-F23RV simplifies complex toilet installations that require additional ventilation. This flexible connector includes an integrated 1¼” universal vent boss. You can easily connect an air admittance valve or extra venting pipework to this boss. Additionally, we include a blanking cap, which allows you to seal the boss if you do not need it. Since McAlpine manufactures this unit from durable polypropylene, it offers a reliable, long-term solution. It also fits the 4″/110mm internal diameter of PVC-U and cast iron soil pipes, making it an essential tool for difficult bathroom layouts.

• Integrated Vent Boss: The 1¼” universal vent boss helps systems that require extra air intake or ventilation.
• Convenient Blanking Cap: You can easily seal the boss using the supplied blanking cap whenever it remains unused.
• Flexible Adjustability: This unit provides an effective length of 150–280mm. It helps you bridge tricky gaps between the pan and the soil stack.
• Universal Compatibility: The 97–107mm inlet fits all standard pan spigots. Furthermore, the outlet connects to 4″/110mm PVC-U and cast iron pipes.
• Hygienic Design: Independent tests confirm that the bellows design prevents sediment build-up. Consequently, you receive consistent waste flow performance.

Details

Toilet installations often reveal poor ventilation in the soil system. This lack of air causes gurgling sounds, slow drainage, or trapped odours. Usually, plumbers find that retrofitting a vent pipe into a finished bathroom requires destructive work like opening walls or floors.

The McAlpine WC-F23RV eliminates these difficulties. Because it integrates a vent boss directly into the connector, you gain an immediate access point for ventilation. Therefore, you solve both connection alignment and system venting issues in one efficient step. Ultimately, your bathroom plumbing will operate quietly and effectively.
