Signs your anode needs replacing
Discoloured or rusty hot water, or a tank that's around five years old and has never had an anode check. On rainwater or bore supply, anodes are used up faster.
What's involved
We isolate and partly drain the tank, remove the old anode, check its condition and fit the right replacement for your water supply. The job usually takes about an hour.
Which systems have anodes?
Vitreous enamel-lined electric, gas, heat pump and solar storage tanks have anodes. Stainless steel tanks and continuous flow units don't.
Common questions
How often should a hot water anode be replaced?
Around every five years on town water, and every two to three years on rainwater or bore water. An inspection shows how much is left.
Is anode replacement worth it?
On a tank that isn't leaking yet, yes. It costs a fraction of a new system and protects the tank from corroding through.
