Common Hot Water Repair Problems (and How We Fix Them)

aussie-services-staff-van

“My hot water system isn’t heating up at all.”

This could be due to a faulty heating element, a broken thermostat, or gas supply issues. Our team diagnoses the exact cause and repairs or replaces the defective components to restore your hot water.

“The water temperature keeps fluctuating between hot and cold.”

This issue is often caused by sediment buildup in the tank, a malfunctioning thermostat, or an inconsistent gas supply. We flush the system, replace faulty parts, and check gas connections to ensure a stable water temperature.

“There’s water leaking from my hot water tank.”

A leaking tank can indicate corrosion, a faulty pressure relief valve, or a damaged seal. Our plumbers identify the source of the leak, repair any seals or valves, and advise if a tank replacement is needed.

“I have low water pressure when using hot water.”

This could be due to sediment clogging the pipes, a blocked filter, or a faulty valve. We perform pressure tests, clear blockages, and adjust the system to restore proper water flow.

“My gas hot water system has stopped working.”

Gas water heaters can fail due to pilot light issues, gas supply interruptions, or burner malfunctions. We inspect the gas hot water system, relight pilot flames, and ensure the gas connections are secure and functioning correctly.

Repair or replace your hot water system?

Many faults are worth repairing: a failed thermostat or element on an electric unit, a faulty valve or ignition problem on gas, or a leaking fitting. A tank that is leaking from the cylinder itself usually cannot be repaired, because the tank has failed.

The deciding questions are the age of the unit, the cost of the repair against a new system, and how often it has failed before. We explain the options plainly, and if replacement is the better choice, see hot water systems for what we install. For a system that has stopped heating overnight, our emergency plumbers are on call.

I had a great experience with Aussie Services, especially with Luke, who came out to fix a blocked drain at my property. Luke was extremely professional, friendly and approachable. He took the time to explain the cause of the blockage, clearly explained what needed to be done, and resolved the issue efficiently. I really appreciated his knowledge, honesty and willingness to help. It's refreshing to deal with someone who genuinely takes pride in their work and provides excellent customer service. Highly recommend Luke and Aussie Services. I'll definitely use their services again in the future!

Very happy with the plumbing work done by Luke and his team. It was a big job but it was carried out with minimal disruption to the household, and the yard. Luke was always good in explaining how the job was progressing, and importantly when we had windows of opportunity to use the sewerage system during the day. They finished the job in a timely manner, and cleaned up afterwards. Happy to recommend this company.

Called and booked for Monday, given between 8 and 12pm for a possible gas leak. Chris showed up 1 minute after he called as he was just around the corner. Chris was polite, informative and professional. Checked all my appliances, one by one and the main meter. Lucky there was no leak and it was a billing issue. Better to be safe than sorry. Also as a first time customer received a discount which was nice as I saw on line if you mention it they knock it off the total price. Zero call out fee and all work quoted up front fixed price. Would highly recommend Aussie Home Services. Its hard yo find great trades these days and Chris fits the bill! Thank you.

We called out Aussie after hours on a long weekend on Grand Final night as we had no power. Not only did they answer, (a real person as well) they sent a level 2 electrician (Paul was highly skilled, extremely professional and a nice person to boot) out who fixed what was a serious issue, all I a few hours.. bravo all round
