What it is
This is the domestic water pipe section that runs from the shut-off valve to the flow switch, manufactured by Worcester Bosch. It forms part of the domestic hot water circuit on the Greenstar Heatslave II ErP range of oil-fired condensing boilers. The pipe carries the domestic water path between the shut-off valve and the flow switch assembly.
Signs this part needs replacing
- Water weeping or tracking along the pipe at the shut-off valve or flow switch connection
- Corrosion, pitting or green/white scale staining on the pipe surface or at the fittings
- Reduced or interrupted domestic hot water draw-off caused by a restricted pipe bore
- Flow switch failing to trigger, with the boiler not responding to a hot water demand
- Visible deformation or cracking of the pipe section after frost damage or excessive tightening
Before you order
- Confirm the appliance model against the fit list, including whether it is a standard or EXT variant
- Check the pipe routing on the appliance and identify the run between the shut-off valve and the flow switch
- Inspect the mating fittings and washers at both ends, as these are separate items and may also need attention
- Have the manufacturer part number 87186841390 to hand when ordering
