What it is
The Worcester Bosch 8 litre Type E-W flow regulator is a water flow control component used across a wide range of Worcester Bosch heating and hot water appliances. It governs the direction and rate at which fluid moves through the system, and in some circuits it also acts as a check valve, stopping fluid from drifting into areas where it should not go. It is a direct replacement part for the original fitted to Greenstar, CDI and older Worcester models.
Signs this part needs replacing
- Domestic hot water flow rate drops or becomes inconsistent at the tap
- Water temperature fluctuates or the appliance cycles when a tap is running
- The regulator body shows scale build-up, debris or physical damage
- Backflow or cross-flow between circuits that the check valve function should prevent
- Leaks or weeping around the regulator housing or its connections
Before you order
