The 21.5mm Overflow Push-Fit / Solvent Weld Equal Tee (Grey) is a compact, durable uPVC waste fitting designed to connect three sections of 21.5mm overflow pipework at a 90° junction. It is primarily used in domestic plumbing applications to combine overflow discharge streams from cold water storage cisterns, central heating pressure relief valves, or toilet cisterns into a single common waste run.
 
Featuring a versatile multi-function socket design, this fitting accommodates either a secure push-fit installation using integrated rubber ring seals or a permanent, rigid connection via standard uPVC solvent cement. The smooth internal bore ensures efficient hydraulic discharge while preventing the accumulation of scale or debris.
 
Manufactured from lightweight, impact-resistant, and UV-stabilized uPVC, the grey finish provides a seamless aesthetic match with modern grey waste systems, soil stacks, and external architectural finishes. It complies with relevant UK plumbing standards (BS EN 1455-1), delivering a dependable, leak-free solution for both internal and external discharge routing.
