What it is
The 87161410310 is Worcester's Type E flow regulator, colour-coded lime to denote its 15 litre-per-minute rating. It is fitted inside the cold water inlet to cap the flow rate through the plate heat exchanger, matching flow to the boiler's heating capacity so the water reaches the correct temperature.
Signs this part needs replacing
- Hot water flow rate has dropped noticeably at taps and showers
- Water runs hotter than expected because flow through the exchanger is restricted
- Regulator insert is visibly split, deformed or has debris lodged in it
- Boiler struggles to reach set temperature at higher flow rates
Before you order
- Match both the part number 87161410310 and the lime colour code (15 litre rating) to your existing regulator; other colours denote different flow rates and are not interchangeable
- Confirm your exact boiler model before ordering
- Isolate the water supply before removing the old regulator
- Fitting should be carried out by a Gas Safe registered engineer where the work involves the gas-fired heat exchanger assembly
