What it is
The Baxi 248226 is a tap isolation valve supplied for the domestic hot water return on Baxi heating appliances. It sits in the DHW circuit and lets an engineer shut off the flow to that section of the appliance so work can be carried out without draining the whole system. It is a Baxi-manufactured spare, listed under the cocks and taps category.
Signs this part needs replacing
- Water weeping from the valve spindle or body when the appliance is running
- The handle turns freely without shutting off the DHW return
- The valve is seized and cannot be operated by hand
- Water continues to pass through the valve in the closed position
- Scale or corrosion visible around the valve body or connections
Before you order
- Check the appliance serial plate and GC number against the compatibility list to confirm the part suits your model
- Compare the part number on the existing valve with BAXI248226 before ordering
- Inspect the sealing washers and connections on removal, as these may need renewing at the same time
- Isolate and drain the relevant circuit before fitting, and confirm the DHW return is fully shut down afterwards
