What it is

The Spirotech 1.25 MBL is a Spirotech product carrying the 1.25 MBL size designation. It is supplied for use in boiler and heating system applications, where it forms part of the system's ancillary equipment. It is listed as a single item under SKU UE125WJ.

Signs this part needs replacing

  • Heating output has become uneven, with some radiators or zones slower to warm than others.
  • System water drawn off at drain points is discoloured or carries visible debris.
  • The installation point shows weeping, staining or other signs of a failing seal.
  • The unit no longer matches the 1.25 MBL designation required by the system or appliance it serves.

Before you order

  • Confirm the size designation on the existing unit is 1.25 MBL and matches the product name shown here.
  • Check the manufacturer's literature for the appliance or system to confirm this item is the correct component for the installation point.
  • Confirm whether any seals, washers or connecting parts are required separately, as none are listed with this item.
  • Verify the system has been isolated and depressurised before any work begins.
