What it is
This is Main's water valve assembly, fitted to the Multipoint BF water heater range. It regulates internal water flow, so a faulty or sticking valve typically shows up as no hot water, low flow, or intermittent operation.
Signs this part needs replacing
- No hot water, or hot water that cuts in and out
- Low or inconsistent water flow from the appliance
- Water dripping or leaking from the valve body
- Appliance fails to fire on demand for hot water
Before you order
- Match the part number printed on your existing valve before ordering
- Isolate the water supply before removal
- Have this fitted by a Gas Safe registered engineer
