Safety first: if you smell gas, turn the gas off at the meter, open doors and windows, don't touch electrical switches, and call us (or for major leaks, the gas emergency line 13 13 52). If the system is flooding, turn off its cold-water isolation valve (or the mains) and call straight away.

The 5 checks

1. Is it just the hot water?

Run a cold tap. If cold water is also off or weak, the problem is your water supply, not the hot water system — check for Water Corporation outages in your suburb before anything else.

2. Electric system? Check the switchboard.

Find your meter box and look for a tripped breaker labelled "hot water" or "HWS". If it's off, flip it back on once. If it trips again, stop — that's a fault (often a failed element) that needs a repair visit.

3. Gas storage system? Check the pilot light.

Look through the viewing window near the bottom of the tank. No small blue flame? Follow the lighting instructions printed on the unit. If the pilot won't stay lit, it's usually the thermocouple — a quick, inexpensive fix for a licensed gas fitter.

4. Check your gas supply.

If you have gas continuous flow or storage, is another gas appliance (cooktop) working? If not, the issue is supply — check the meter valve is on, or for LPG homes, that the bottles aren't empty. Note that many newer northern estates have no gas at all — in that case your system will be electric and check #2 applies.

5. Look and listen at the unit.

Water pooling around the base? Rumbling or popping sounds? Rusty water from hot taps? These point to a tank that's failing — see repair vs replace for what that means.

Still no hot water?

Then it's almost certainly a component fault — element, thermostat, gas valve or similar — and that's a quick job for a licensed plumber with the right parts. Most faults are fixed in a single visit, and where a system genuinely needs replacing, same-day installation is usually possible when you call in the morning.

Frequently asked questions

What should I check first with no hot water?

Cold water supply, the switchboard breaker, the pilot light (gas storage), gas supply, and signs of leaking. If none solve it, it's a component fault needing a plumber.

Is no hot water an emergency?

It's urgent but not dangerous on its own. It becomes an emergency if the system is flooding, you smell gas, or it's making loud banging or hissing sounds — isolate the supply and call immediately.

How fast can hot water be restored?

Many faults are fixed in one visit. If replacement is needed, same-day installation is usually possible when you call in the morning.
