What it is
The Vaillant 0020183718 is a flow restrictor used in ecoTEC PRO 22 and ecoTEC PRO 26 appliances. It limits the volume of water passing through the relevant circuit so the boiler can hold its designed flow rate. This variant is specified for units supplied in Guernsey and Jersey only.
Signs this part needs replacing
- Reduced flow rate at hot water outlets
- Boiler failing to reach its expected delivery temperature
- Scale or debris build-up restricting the restrictor orifice
- Water passing or weeping around a damaged restrictor
- Flow-related fault codes or lockouts on the appliance
Before you order
- Confirm the appliance model and build revision match the list above
- Check whether the installation is a Guernsey or Jersey variant, as this restrictor is specified for those only
- Inspect the existing restrictor for scale, damage or incorrect fitment before ordering
