Replacement signs

Noticing these hot water issues?
It may be time for a replacement.

Loss of hot water, leaks, rust or unusual noises can mean your system needs attention. Our plumbers can assess whether a repair or replacement makes sense.

No hot water or inconsistent temperature

If the water keeps going cold, takes too long to heat, or can’t keep up with the household anymore, the system may be failing.

Rusty or discoloured water

Brown or rusty water can point to internal corrosion, especially in older storage systems.

Leaks or water around the unit

Any pooling water, dripping, or visible leakage around the tank should be checked quickly to avoid bigger damage.

Popping, banging or unusual noises

Strange noises can happen when sediment builds up inside the tank, which may mean the system is aging or inefficient.

Older system reaching end of life

Many storage hot water systems start becoming more problematic as they get older, especially once they’re well past their prime.

Rising bills or frequent repairs

If you keep spending money on repairs or noticing poor efficiency, replacement can be the better long-term move.

Did you know?

Four quick hot water facts.

1. Not every household needs the same system.

The right replacement depends on how many people live in the home, how much hot water you use, and whether you’re better suited to storage, continuous flow or another option.

2. A like-for-like replacement is often fastest.

If your new system is similar to the existing setup, replacement is usually more straightforward and can often be handled quickly.

3. A failing hot water heater can increase your energy bills by up to 30%.

Sediment build-up inside your system forces it to work harder to heat water, wasting energy and money. Regular servicing keeps your heater efficient, lowers power bills, and extends its lifespan.

4. Most hot water heater breakdowns give warning signs weeks before failing completely.

Noisy banging, fluctuating water temperatures, rusty water, or reduced pressure are early indicators of internal damage.

Our stormwater was completely blocked after some heavy rain and we were starting to get water pooling around the house. Peter from AusPlumbing came out and sorted it out for us. Explained what was causing the problem and got everything working properly again. Great local plumbing company.

We were having repeated drainage issues and decided to get a camera inspection done rather than just keep clearing the blockage. Peter from AusPlumbing ran the camera through the sewer and showed us exactly where the problem was. Very …

Called AusPlumbing late in the day with an urgent plumbing problem at our home in Cronulla. Donovan answered straight away and had someone out to us very quickly. They found the problem, repaired it and had everything back to normal. It’s hard to find tradesmen who actually respond when you need them. Great service.

Really happy with the work. They installed a new shower and two toilets, ran new hot/cold water lines and new drainage, and connected everything neatly to the existing sewer. Great communication, arrived on time, and the job was done properly. Highly recommend.
