• Water weeping or dripping at the flow tube connection points
• Staining, corrosion or crusting around the tube joint on the boiler casing
• Visible splitting, hardening or flattening of the tube or its gasket
• Scale build-up or heat damage restricting flow through the tube
• Repeated loss of system pressure traced to the flow tube assembly

• Confirm the appliance model and serial number against the compatibility list before ordering, as the same part number is shared across several Viscount ES and CFE variants.
• Check the number stamped or printed on the existing component and compare it with 066126 and the alternative numbers listed above.
• Inspect the gasket seating face while the tube is removed; a replacement seal may be needed if the face is pitted or scaled.
• Work on the boiler water circuit should follow the manufacturer's instructions, with the appliance isolated and drained as required.
