The 21.5mm Overflow Push-fit / Solvent Weld Tank Connector (White, Ref: EOS08W) is a heavy-duty uPVC bulkhead fitting designed to create a watertight outlet connection through the wall of a cold water storage tank, cistern, or overflow vessel. It provides a secure transition point to connect a 21.5mm overflow pipe run to lead warning discharge water safely away from the appliance.
 
Featuring a threaded male body with a heavy-duty backnut and high-grade rubber sealing washer, it clamps firmly onto the side or end wall of a water tank to form a robust, leak-free compression seal. The outlet socket is dual-compatible, allowing for a fast push-fit connection using compatible internal rubber seals or a permanent joint using standard uPVC solvent cement.
 
Manufactured from durable, corrosion-proof, and UV-stabilized uPVC to UK standards (BS EN 1455-1), the clean white finish integrates seamlessly with standard 21.5mm white overflow pipework systems. It is an essential component for ensuring compliance with UK Water Regulations (WRAS) regarding emergency overflow warning pipes on water storage systems.
