What it is
The Ideal 172492 Expansion Vessel Pipe Kit is an internal pipework assembly for Ideal Isar and Icos system boilers. It carries water between the expansion vessel and the boiler's hydraulic circuit, keeping the connection correctly routed inside the casing. The kit is supplied under the Ideal Spares brand and is listed under the Pipes & Hoses spare part type.
Signs this part needs replacing
- Water weeping, dripping or white staining around the expansion vessel connection
- System pressure dropping on the boiler gauge and returning only briefly after topping up
- Corrosion, pitting or green scale on the pipe surface at the union joints
- Kettling, knocking or gurgling noises coming from the vessel area
- Boiler locking out on a low-pressure fault after the system has been refilled
Before you order
- Read the model and serial number from the appliance data badge; Isar and Icos variants use different internal layouts, so match the part to the exact boiler.
- Compare the number stamped or printed on the old pipe with 172492 before ordering.
- Inspect the sealing washers and O-rings at the vessel connection and replace any that have hardened, flattened or perished.
- This is not a gas-carrying component, but any work inside the boiler casing should be carried out by a competent person.
