What it is
The Vaillant 0020231126 is a flow limiter rated at 10 L/min, fitted within the water circuit of compatible Vaillant combi and system appliances. It regulates the volume of water passing through the appliance so the stated flow rate is maintained during draw-off. It is a serviceable component used when the existing limiter is restricted, damaged or removed during repair work.
Signs this part needs replacing
- Hot water flow rate at the outlet is noticeably lower than the appliance's rated delivery
- Flow rate fluctuates or drops away as the tap or shower runs
- The limiter is blocked with scale or debris and cannot be cleaned back to its rated flow
- The limiter has been removed or damaged during earlier repair work and needs reinstating
- Water passes at a rate above the intended 10 L/min, affecting temperature stability at low draw-off
Before you order
- Confirm your appliance model and GC number against the fit list above
- Check that the existing limiter is rated at 10 L/min before ordering
- Verify the part number 0020231126 matches the number on the component being replaced
- Check the pack quantity suits the number of appliances being worked on
