The Baxi 248224 Isolation Flow Tap is a genuine replacement component designed to allow safe and controlled isolation of the central heating flow circuit on compatible Baxi boilers. This isolation tap enables engineers to shut off the water supply to the boiler during servicing, maintenance, pressure testing, or repairs without the need to drain the entire heating system. Precision-engineered to Baxi’s exact quality standards, it ensures a secure seal, smooth operation, and long-term reliability under normal system pressures.

This isolation flow tap is compatible with Baxi Duo Tec and Baxi Combi boiler models that utilise this specific flow isolation fitting. It is typically replaced if the original tap becomes stiff, leaks, or fails to fully isolate the system during servicing.

Using a genuine Baxi isolation flow tap helps support efficient servicing procedures, prevents unnecessary water loss, and contributes to the safe, reliable, and long-term operation of your central heating and hot water system.
