The FloPlast Overflow Coupling is an essential component for DIY enthusiasts and professional plumbers alike, designed specifically for extending or joining 21.5mm overflow pipes. It offers a secure, reliable connection for drainage systems and features a clean, high-gloss white finish that blends perfectly with modern building exteriors. While it provides excellent durability and a maintenance-free experience, users should ensure they are using it exclusively with compatible 21.5mm pipe systems to avoid leakage.

No, this coupling is designed specifically for gravity-fed overflow and drainage systems and is not suitable for high-pressure water applications.
The FloPlast Overflow range is designed for a push-fit connection, so no glue or solvent welding is typically required for standard overflow drainage.
The material is designed to be color-stable and resistant to UV degradation, maintaining its white finish for long periods.
While it may fit other 21.5mm pipes, it is highly recommended to use FloPlast branded components to ensure optimal seal performance.
Yes, it can be used for internal overflows, such as those found in vanity or bathroom installations.
Ensure the pipe is pushed fully into the coupling until it hits the center stop. Check that the pipe end is cut square and is free from jagged edges.
Verify that your pipe is exactly 21.5mm. If there is debris inside the coupling or a burr on the pipe, remove it before re-attempting insertion.
Installation of the FloPlast Overflow Coupling is straightforward and requires no complex adhesives or soldering. First, ensure the 21.5mm pipe is cut cleanly and the end is deburred to prevent damage to internal seals. Slide the pipe firmly into the coupling until it is fully seated. For long-term care, simply wipe the coupling with a damp cloth if it becomes dirty. It is fully compatible with all standard FloPlast 21.5mm overflow components. Avoid using harsh chemical solvents, as these may damage the plastic surface finish over time.
