The 21.5mm Overflow Push-fit / Solvent Weld Equal Tee (White, Ref: EOS07W) is a compact, high-grade uPVC waste fitting designed to join three sections of 21.5mm overflow pipework at a 90° junction. It is commonly used in domestic plumbing to combine overflow relief runs from cold water storage cisterns, boiler condensate lines, and toilet flush cisterns into a single discharge pipe.
 
Featuring a dual-compatibility socket design, this fitting allows for versatile installation methods using either push-fit connection with compatible rubber seals or a permanent, solvent-welded joint using uPVC solvent cement. The smooth internal bore ensures unrestricted water flow, minimizing the risk of air locks or debris buildup during emergency cistern overflows.
 
Manufactured from lightweight, impact-resistant, and UV-stabilized uPVC, the clean white finish matches standard 21.5mm overflow piping and exterior building soffits. It conforms to relevant UK plumbing standards (BS 2494 / BS EN 1455-1), delivering a leak-free, durable connection for both internal and external waste discharge setups.
