What it is
The Grant MPCBS124 is a 3 bar pressure relief valve with a pressure gauge port, produced by Grant for its oil-fired Combi boiler range. It opens at its set pressure to discharge excess water from the heating circuit, protecting the appliance and connected system components from over-pressurisation. The gauge port allows a pressure gauge to be fitted directly at the valve.
Signs this part needs replacing
- Water discharging continuously from the valve outlet or discharge pipe
- The valve lifting and then failing to reseat, leaving a steady drip
- System pressure creeping above the normal cold-fill reading
- Scale or debris on the valve seat causing a persistent weep
- Pressure gauge readings climbing as the boiler reaches temperature
Before you order
- Confirm the boiler model and GC number against the compatibility list before ordering.
- Check the valve currently fitted for the previous number MPCBS50X to confirm the same fitment.
- Inspect the sealing washer at the valve connection and renew it if it is compressed or perished.
- This is a non-gas part.
