What it is
The Ideal 004944 is a diaphragm grommet, a small sealing component used in the diaphragm assembly of Ideal Classic FF boilers. It seats the diaphragm against its housing so the pressure-sensing side of the assembly stays sealed in service. The part is supplied by Ideal as a direct replacement for the original fitted item.
Signs this part needs replacing
- Water or air weeping from around the diaphragm housing
- Visible cracking, hardening or flattening of the grommet where it seats
- Loss of pressure or erratic operation traced to the diaphragm assembly
- Discolouration or perishing of the rubber after long service
- A grommet that no longer sits squarely in its recess when the housing is opened
Before you order
- Check the GC number on the appliance data badge against the compatibility list to confirm the model
- Confirm the existing part number and any alternative number marked on the old component
- Inspect the surrounding diaphragm and seals while the housing is open, as these are often replaced at the same time
- Have the appliance reassembled and checked by a competent engineer before returning it to service
