What it is

The Grant MPCBS81 is a 28mm non-return check valve for Grant Vortex Pro combi condensing boilers. It fits into the pipework to permit flow in one direction only, preventing backflow within the heating circuit. It is listed as a spare for both internal and external Vortex Pro combi models.

Signs this part needs replacing

  • Flow continues in the wrong direction when the valve should be closed
  • Circulation or heat output drops when the system should be holding
  • Repeated cycling or uneven heating caused by backflow
  • Debris, scale or visible damage around the valve body
  • Leaks from the valve body or its connections

Before you order

  • Confirm the boiler is a Grant Vortex Pro internal or external combi condensing model
  • Check the pipework at the valve position measures 28mm
  • Note the flow direction arrow on the existing valve before removal
  • Have the boiler model and part number to hand when ordering
