What it is
The Worcester Bosch 8716118468 is a 25 litre flow restrictor used in the manufacturer's domestic heating and hot water appliances. It sits in the water circuit and limits the volume of water passing through to the rated figure, keeping flow within the range the appliance is designed to work at. It is catalogued as a flow regulator and is used across a number of Greenstar Heatslave II and Greenstar Highflow models.
Signs this part needs replacing
- Hot water flow rate noticeably below the appliance's rated output
- Flow that varies between outlets, or drops when a tap is opened elsewhere
- Scale or debris collected around the restrictor, narrowing the bore
- Water passing at a higher rate than the 25 litre rating, upsetting temperature control
- Weeping or leaks at the restrictor seating
