What it is
The FLOW REGULATOR N-W-LP 9 L/MIN ORANGE is a Worcester Bosch flow regulator, supplied as part number 8737603924. It is identified by its orange body and a rated flow of 9 L/min. The regulator sits in the appliance water circuit and controls the rate at which water passes through it, supporting stable operation of the boiler.
Signs this part needs replacing
- Flow rate through the appliance is lower or less consistent than expected
- The regulator is restricted by scale or debris carried in the water circuit
- Water is weeping from the regulator body or its connections
- The orange body shows cracking, deformation or other physical damage
- The appliance behaves erratically because flow through the circuit is not being held at the intended rate
Before you order
- Confirm the appliance model and GC number against the fitment list before ordering
- Check the existing regulator for the orange colour coding and the 9 L/min marking
- Inspect the surrounding pipework and connections for scale or debris that may have caused the original fault
- Verify the part number 8737603924 matches the number shown on the appliance or in its documentation
