Davant 21.5mm Black Solvent Overflow Equal Tee

The Davant 21.5mm Solvent Overflow Equal Tee is a versatile and practical fitting designed to connect three sections of 21.5mm overflow pipe. Shaped in a classic "T" formation, it allows you to split or join overflow pipework efficiently—making it perfect for installations where multiple branches need to be directed from a single flow path. Available in a black finish (with white options often available), this fitting is ideal for both functional and discreet installations in cold water storage systems, cistern overflows, or any system designed to safely divert excess water. Its simple design ensures a neat and reliable connection between pipe sections, helping to maintain consistent flow and prevent leaks. This equal tee is designed for use with solvent weld systems, meaning it must be fixed in place using solvent cement. Once applied, the bond becomes strong, permanent, and leak-free—perfect for systems that don’t require regular disassembly and where long-term performance is key. Whether you’re a professional plumber or working on a DIY project, this equal tee makes it easy to customise and expand your overflow system with confidence.

Frequently Asked Questions

What is an “equal tee” fitting?

An equal tee connects three pipes of the same diameter—in this case, 21.5mm. It allows fluid to flow from one pipe and be split into two, or to merge two flows into one outlet, depending on the installation.

Do I need solvent cement to install this fitting?

Yes, this is a solvent weld fitting. For a secure and leak-proof connection, you’ll need to use solvent cement on both the pipe ends and the inside of the tee before joining them together.

Can this be used in outdoor overflow systems?

Yes, the black version is well-suited for external use, particularly in shaded or protected areas. It offers better UV resistance than white fittings, but for long-term exposure, additional protection is recommended.

Roof Tiles & Fittings:

We recommend ordering an additional 10% of roof tiles to allow for any breakages that may occur during delivery or handling. Roof tiles are naturally fragile, and having a few extra on site helps prevent delays and ensures your roofing project can be completed without interruption.
