Ideal Expansion Vessel Pipe Kit 175416

The Ideal 175416 Expansion Vessel Pipe Kit is an internal pipework component used on Ideal domestic gas boilers. It forms part of the pipe run associated with the expansion vessel, keeping the water path correctly routed within the appliance casing. The kit is supplied under the Ideal Spares brand and is common to several Esprit 2 and Evo HE variants.

• Pressure loss on the heating circuit with no obvious leak elsewhere on the system
• Water weeping, damp staining or crusting around the expansion vessel connection
• Corrosion, scale or pitting visible on the pipe surface or at the joint
• Vibration or unusual noise from the pipe run when the boiler fires
• Pipework that has been disturbed, kinked or strained during previous servicing

• Check the GC number on the appliance data badge against the compatibility list to confirm the correct variant.
• Confirm the boiler model and serial number, as this pipe kit is used across a number of Esprit 2 and Evo HE builds.
• The alternative number 1780888 may appear on older documentation, stock labels or ordering systems.
• Check whether new seals or washers are required at the connection points before fitting.
