What it is
The Ravenheat 5012051 is a diaphragm kit for the 3-way diverter valve used in Ravenheat gas boilers. The diaphragm sits inside the diverter valve and moves the valve to switch the boiler between central heating and domestic hot water. It is a service part for the RSF, CSI and HE appliance families.
Signs this part needs replacing
- No hot water or intermittent hot water when a tap is opened
- Diverter valve fails to switch between central heating and hot water
- Radiators heat up when only hot water is demanded
- Reduced or fluctuating domestic hot water flow
- Water weeping from the diverter valve body or diaphragm housing
Before you order
- Confirm your boiler model and GC number against the fitment list
- Check the diverter valve uses a diaphragm kit rather than requiring a complete valve assembly
- Isolate the boiler and depressurise the system before fitting
- Inspect the valve body for wear or damage that a diaphragm kit alone will not resolve
