Ideal Water Flow Flange 170254

The Ideal 170254 is a water flow flange supplied with its matching gasket. It is a manufacturer-supplied component for Ideal Commercial appliances, forming the bolted connection where the water circuit meets the boiler's flow path. The flange seats against the mating face and the gasket provides the seal, so the assembly must be fitted squarely and tightened evenly to keep the joint watertight under normal operating pressure and temperature.

• Weeping or visible water tracking around the flange joint, often showing as staining or scale on the casing below
• A persistent drip that returns after the joint has been re-tightened
• Gasket that has hardened, flattened or split when the joint is opened
• Corrosion or pitting on the flange face that prevents the gasket from sealing
• Pressure loss on the system that traces back to the flow connection rather than the pipework

• Confirm the appliance model and, where available, the serial number against the compatibility list before ordering
• Check the existing flange and gasket on the appliance to confirm the connection pattern matches the replacement
• Have a replacement gasket to hand if the existing one is disturbed, as the joint seal is not reusable once compressed
• Work on the boiler water circuit should be carried out by a competent engineer, with the appliance isolated and drained as required
