When repair makes sense
Slow heating, no heat, protection tripping, noise or a flange leak may be repairable. Isolate the electrical supply first and shut off water if the leak requires it.
Signs replacement is likely
Water emerging from the cylinder body or visible perforating corrosion usually means the pressure vessel cannot be restored reliably. Age, parts availability, efficiency and circuit condition also matter.
Why a heater trips the breaker
Possible causes include an element leaking current, moisture, cable damage or a hot terminal. Do not keep resetting the protection or fit a larger breaker.
What the technician tests
Supply, protective devices, thermostat, element, insulation resistance, flange, valve and the exact leak source. Only then can repair and replacement costs be compared.
Photos for an initial estimate
Send the full installation, leak point, water connections, outlet or cable and model label. Never open the electrical cover while energised.
Frequently asked questions
Can I use a heater that is dripping?
First identify the source. Safety-valve discharge during heating is different from a leaking cylinder; isolate an unexplained leak.
Why is heating taking longer?
Scale, a weakened element, low voltage, settings or increased hot-water use can all contribute.
Is an old heater worth repairing?
It depends on cylinder condition, parts cost and safety. Corrosion of the vessel usually favours replacement.
