The McAlpine WC-F26S is a flexible WC connector used to connect the waste outlet of a toilet bowl to a soil pipe. The connector has an inlet diameter of 97-107mm and an outlet diameter of 3.5"/90mm. The flexible nature of the connector allows for some degree of movement and adjustment, making it easier to install in tight spaces or when the toilet is not perfectly aligned with the soil pipe. When installing the McAlpine WC-F26S, it's important to ensure that the connector is properly aligned and securely fitted to both the toilet bowl and the soil pipe. Any leaks or misalignments can lead to unpleasant odors and potential water damage. It's also worth noting that while flexible connectors can be useful in certain situations, they may not always be the best choice. In some cases, a rigid connector may be necessary to ensure a secure and leak-free connection. It's important to consult with a qualified plumber or building professional to determine the best connector for your specific installation.
