What it is
The diverter valve dummy is a Vaillant component (part number 0020231124) used in place of a diverter valve on appliances that do not require a diverter function. It seals and blanks the relevant port in the hydraulic assembly, maintaining the water circuit on the listed models. It is a service part for the Home System and Ecofit PURE and Sustain ranges.
Signs this part needs replacing
- Water weeping or dripping from the dummy valve position on the hydraulic block
- Visible scale, corrosion or pitting on the dummy body or its sealing face
- Traces of water staining or residue around the port on the appliance casing or block
- Loss of system pressure with no other obvious source of leakage
Before you order
- Confirm the appliance model and variant against the fit list above
- Check the part number on the existing component or the manufacturer's parts list for your appliance
- Inspect the sealing face and surrounding hydraulic block for damage before fitting
- Verify whether any seals or O-rings are required separately, as they are not confirmed as included
