What it is

The MPCBS81B is a genuine Grant 28mm non-return valve, a spare part listed on Grant UK's own oil boiler spares pages for the Vortex Pro combi built after April 2011. It prevents backflow within the boiler's pipework.

Signs this part needs replacing

  • Backflow or water hammer noise in the pipework
  • Reduced or reversed flow through the affected pipe run
  • Visible leaking or weeping from the valve body
  • Internal boiler faults linked to circulation faults on the affected circuit

Before you order

  • Confirm your Vortex Pro combi was built after April 2011
  • Match the part number printed on the existing valve
  • Isolate and drain the relevant pipework before removal
