Ideal Corrosion / Sludge in System

Rust-coloured or dirty water from hot taps served by the Ideal water heater.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Corroded cylinder or pipework, Sludge in primary circuit, Deteriorated sacrificial anode (if fitted), Old steel pipework

Safety: Discoloured water may stain fixtures; avoid using for laundry until resolved.

Check if cold water is clear: If only hot water is affected, the issue is likely in the heater or associated cylinder/pipework.
Flush system: Run hot taps to flush out stagnant water. If colour persists, further action is needed.
Water quality treatment: A professional can flush and chemically clean the primary circuit and inspect any cylinder for corrosion.
Component replacement: Severely corroded cylinders or pipework may need replacement.
