What it is
The Worcester Bosch 87161412530 is a flow regulator supplied with an integral filter. It sits in the water section of the appliance and governs the rate at which water passes through the domestic hot water circuit, holding flow and pressure steady as demand changes. The filter element captures scale and system debris before it reaches the regulator, protecting the waterway from restriction.
Signs this part needs replacing
- Domestic hot water flow rate drops noticeably, or varies between taps
- Outlet temperature swings while the boiler is running on hot water
- Filter element clogged with scale or black system debris, restricting the waterway
- Whistling or humming from the water section during draw-off
- Repeated scale-related faults or lockouts on the hot water circuit
Before you order
- Check the GC number on the appliance data badge against the compatibility list before ordering
- Confirm the previous number T0199285480 where an older regulator is being replaced
- Inspect the seals and washers on the water section and renew them if they show wear
- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
