Hot water maintenance services from Outright Plumbing
Regular servicing is the key to keeping your hot water system safe, efficient, and long-lasting. At Outright Plumbing, we carry out the essential checks and preventative work that stop minor issues from turning into expensive breakdowns.
Flushing hot water tanks clears out sediment build-up
Over time, minerals and sediment settle at the bottom of storage tanks. This build-up reduces heating efficiency, strains the system, and can cause rumbling noises. A full tank flush removes the sediment so the unit heats water properly and runs more smoothly.
Safety valves need testing to protect your home
Temperature and pressure relief (TPR) valves are vital for preventing tanks from overheating or over-pressurising. If these valves fail, the risks are serious. During maintenance, we test the valves and replace them if needed, ensuring the system is safe and compliant.
Thermostat and element checks keep water temperatures steady
A faulty thermostat or worn element often causes water to run cold or overheat. By testing these components, we make sure your system maintains consistent hot water without wasting energy or putting strain on the unit.
Anode and seal inspections stop corrosion before it spreads
Sacrificial anodes are designed to rust so your tank doesn’t, but they need replacing every few years. Seals and fittings also wear out over time, leading to hidden leaks. Replacing these parts as part of routine maintenance extends the life of the system and avoids costly tank replacements.
Our plumbers share their insights on hot water maintenance
Hot water systems can run for years without obvious problems, but small issues build up quietly. Regular servicing prevents those hidden faults from turning into breakdowns. Here are a few insights from our plumbers on why maintenance matters more than most people realise.
Sediment build-up shortens a system’s lifespan
Melbourne’s water carries minerals that slowly settle at the bottom of storage tanks. Over time, this sediment creates a layer of sludge that reduces heating efficiency, forces the system to work harder, and makes it prone to overheating. It can even cause rumbling or popping noises when the system is running.
When sediment isn’t cleared, it also puts stress on the tank lining, increasing the risk of cracks and leaks. Flushing the tank during servicing is a simple step that prevents this long-term wear and keeps the system running more efficiently.
Small parts make the biggest difference
It’s easy to overlook components like safety valves, thermostats, and sacrificial anodes, but they’re critical to how a hot water system works. Safety valves release pressure and prevent dangerous faults, thermostats keep water at safe temperatures, and anodes protect tanks from rust.
When any of these parts fail, the whole system is compromised. During maintenance, plumbers test and replace these components so the unit remains safe and reliable. Spending a little on small parts often avoids much bigger costs down the track.
Maintenance matters more in older homes
We often see hot water units in older properties that were installed decades ago and never properly serviced. These systems usually sit on ageing pipework, have fittings that don’t meet modern standards, and are more prone to leaks and corrosion.
Regular maintenance makes a big difference here. By checking valves, resealing connections, and monitoring pressure, plumbers can extend the life of older systems and reduce the risk of sudden failures that damage surrounding pipework or cause water damage.
Regular servicing saves money in the long run
Skipping maintenance might feel like a saving, but it usually costs more in the end. Systems that aren’t serviced run less efficiently, use more energy, and are more likely to break down. A breakdown repair often costs far more than preventative servicing.
Consistent maintenance also pushes back the need for a full system replacement. A tank that’s flushed regularly and fitted with fresh anodes can last years longer than one that’s ignored, giving you more value from the original investment.
The key checks we carry out during maintenance
Outright Plumbing’s experts will focus on the things that keep your hot water reliable, safe, and running for years to come.
Preventive care that stops costly breakdowns
We check the important parts like valves, seals, and connections so that small wear and tear doesn’t turn into a major failure. Catching problems early is the best way to avoid sudden cold showers and expensive repairs.
Efficiency checks to keep running costs down
Sediment build-up, worn components, and incorrect settings make your system work harder than it should. We flush the tank, clear the grit, and test the thermostat so the heater runs efficiently and doesn’t waste energy.
Safety testing for peace of mind
Your hot water system carries heat, pressure, and gas, so safety always comes first. We test controls, valves, and pressure limits to make sure everything is working the way it should and your family stays safe.

Helpful answers from the plumbers who do this every day
Hot water systems can be confusing, so we’ve put together clear answers to the questions we hear most often.
What maintenance should be done on a hot water heater?
A hot water heater runs every day, which means parts wear out over time. Routine upkeep keeps the system working properly and stops sudden breakdowns.
When we maintain a hot water unit, we’ll usually:
- Test safety valves so the system can release pressure safely.
- Check for leaks or corrosion around the hot water tank and pipework.
- Flush sediment from a storage hot water system to keep water heating efficient.
- Test the thermostat to make sure water temperature is accurate and safe.
- Inspect plumbing connections to confirm everything is watertight.
These checks extend the life of your hot water system and give you a reliable supply of hot water day to day. Outright Plumbing carries out this work for Melbourne residents who want their system to run smoothly without nasty surprises.
Is it really necessary to flush your hot water heater?
Yes. Flushing a hot water heater is one of the most important parts of ongoing maintenance. Over time, grit and minerals build up in the bottom of the tank. This forces the system to work harder and can cause hot water issues.
If sediment is left to sit inside a tank, it can:
- Reduce efficiency and increase energy bills.
- Shorten the life of your hot water tank.
- Cause banging or popping noises during heating.
- Block valves or pipework, leading to leaks or reduced hot water pressure.
A proper flush keeps your system running efficiently and ensures your system isn’t overworked. Outright Plumbing’s hot water plumbers handle this safely so you can rely on a steady hot water supply throughout Melbourne.
How often should hot water systems be maintained?
Most hot water systems should be maintained every one to two years. Gas hot water systems need checks more often to make sure they’re safe, while electric water heaters can sometimes go a little longer.
Keeping up with regular hot water maintenance helps:
- Extend the lifespan of your current system.
- Keep water heating efficient and costs down.
- Spot problems early before they turn into emergencies.
- Ensure safety features like pressure valves are still working.
Whether you’ve got solar hot water systems, storage hot water tanks, or electric hot water units, Outright Plumbing offers comprehensive hot water checks that are completely in line with Victorian plumbing standards.
How much does hot water system maintenance cost in Melbourne?
Hot water system maintenance in Melbourne usually costs between $150 and $350, depending on the type of system and its condition. A gas hot water system may need more detailed checks, while electric hot water systems are generally simpler.
Costs can vary based on:
- The size and age of the hot water unit.
- Whether it’s a storage hot water system, electric hot water, or gas system.
- If any valves or thermostats need replacing.
- Extra plumbing maintenance that may be needed.
Staying on top of regular maintenance is the best way to avoid bigger bills, like replacing your hot water system altogether. Outright Plumbing gives clear upfront pricing so you always know the cost before work begins.
Why is water discoloured or rusty from my hot water taps?
Rusty or discoloured hot water usually means corrosion or sediment has built up in an old hot water tank. This can affect water temperature, pressure, and the overall quality of your hot water.
Common causes include:
- Corrosion inside the storage hot water tank.
- A sacrificial anode that hasn’t been replaced on time.
- Sediment building up in the base of the hot water unit.
If your water looks rusty, it’s best to have it checked straight away. Sometimes a flush is enough, but in other cases the tank itself may be the problem. Outright Plumbing can inspect the system and also provide leak detection to make sure the pipework isn’t contributing to the issue.
Do you check for gas leaks during hot water maintenance?
Yes. Any gas hot water system should always be checked for leaks. A gas leak is a serious safety risk and part of every maintenance job we carry out.
When we maintain gas systems, we’ll:
- Inspect gas lines and fittings connected to the hot water unit.
- Check for signs of corrosion or the smell of gas.
- Test that the unit is burning cleanly and safely.
If we find anything concerning, we can carry out gas leak repair straight away. Outright Plumbing’s licensed plumbers give you peace of mind knowing your hot water system is safe.
Do you inspect both the plumbing and electrical connections?
We do. Many hot water systems rely on both plumbing and electrical connections, and ignoring one side of the unit can lead to hidden problems.
During maintenance, we’ll:
- Inspect all hot water plumbing connections for leaks, pressure, and wear.
- Check electrical controls to confirm the thermostat and safety switches are accurate.
- Test that plumbing and electrical features are working together as designed.
This way, your hot water system is functioning properly from every angle. Outright Plumbing offers expert hot water maintenance across Melbourne so you’re not caught out by a hidden fault when you need hot water most.
Will you give me a report after the maintenance is complete?
Yes. Once we finish, you’ll get a clear rundown of what we checked, what condition your hot water system is in, and whether anything might need attention in the future.
Your report will usually include:
- The state of your hot water system’s tank, valves, and connections.
- Notes on efficiency and any signs of wear or ageing.
- Recommendations for future upkeep or when a new system may be needed.
Having this report means you can plan ahead, avoid sudden emergency hot water call-outs, and budget before issues become costly. Outright Plumbing provides reports after every job so you know exactly how your system is holding up.
