What it is
The Main 5110963 is a diaphragm used in the diverter valve assembly of Main Multipoint water heaters. It responds to changes in water flow through the unit, allowing the valve to operate the burner as hot water is drawn. It is listed as a water heater spare within the diverter valve category.
Signs this part needs replacing
- No hot water produced when a tap is opened, with the burner failing to fire
- The diaphragm is split, stretched or perished when inspected
- Reduced or inconsistent hot water flow that changes with water pressure
- Water weeping from the diverter valve body
- The valve fails to return to its rest position once the tap is closed
Before you order
- Confirm the appliance model is a Main Multipoint BF or Multipoint BF ErP
- Check the GC number on the appliance data badge against the model listed
- Verify the existing part number 5110963 before ordering
- Inspect the full diverter valve assembly for wear beyond the diaphragm
