What it is

The MHS Z848020984 is an internal non-return valve for the water side of a gas boiler. It sits within the appliance's water circuit and allows flow in one direction only, preventing backflow through the water side. It is supplied under the MHS brand and carries the part number Z848020984.

Before you order

  • Confirm the part number Z848020984 against the appliance's documentation or the existing valve.
  • Check that the valve is required for the water side of the circuit, not the gas side.
  • Verify the appliance model and any installation instructions before ordering, as internal valve arrangements vary between boilers.
