Ideal Isolation Valve Assembly CH Flow Pack 175528

The Ideal 175528 is a central heating flow pack supplied as an isolation valve assembly for Ideal and Keston combination boilers. It sits on the CH flow connection and lets the heating circuit be shut off and drained independently of the domestic hot water side, which is what makes it useful during servicing, component replacement and system flushing. The assembly is listed under Ideal Spares and is used across the Logic, Code Combi and Keston ranges.

• Weeping or dripping from the valve body or spindle, often leaving scale or water staining around the CH flow connection.
• The valve will not shut off fully, so the heating circuit cannot be isolated for draining or component work.
• A stiff or seized handle that will not turn through its full travel.
• Water tracking down the pipework or onto the boiler casing after the system has been refilled.
• Repeated pressure loss on the heating side that traces back to the flow connection rather than the rest of the circuit.

• Check the GC number on the appliance data badge against the compatibility list below before ordering, as the same assembly is used across a wide spread of models.
• Confirm the model and serial details on the boiler, since Ideal and Keston badging changed across the production run.
• Inspect the existing seals and washers on the flow connection and replace them if they are compressed or damaged before refitting.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
