Ideal Pump Manifold Kit Isar 171037

The Ideal 171037 is a pump manifold kit used in Ideal Heating domestic and commercial boilers. It forms the hydraulic housing and connection between the circulating pump and the primary water circuit, directing flow through the appliance's heat exchanger and pipework. The kit is built for the Isar family and shares fitment with a number of Evo HE models.

• Water weeping, drips or staining around the pump housing or manifold joints
• System pressure dropping on the boiler gauge without an obvious leak elsewhere
• Pump noise, kettling or poor circulation through the primary circuit
• Boiler locking out or failing to reach temperature during a demand
• Visible corrosion, scale or debris build-up on the manifold body

• Check the GC number on the appliance data badge against the compatibility list to confirm fitment.
• Confirm the existing part number 171037 or the alternative number 1178017 before ordering.
• Have the boiler model and serial number to hand when checking the appliance.
• Any work on the boiler's water circuit should be carried out by a competent heating engineer.
