Maintaining Your Evaporative Cooling System
Imagine stepping into a steaming hot shower after a long day, only to be greeted by a disappointing trickle of lukewarm water. Or worse, waking up to a flooded basement caused by a burst water heater. These scenarios are all too common for homeowners who neglect regular maintenance on their hot water systems.
Why Regular Hot Water System Maintenance is Essential
Just like your car needs routine oil changes and tune-ups, your hot water heater requires periodic TLC to keep it running efficiently and reliably. Regular maintenance can:
Extend the lifespan of your hot water system by up to 50%
Improve energy efficiency and reduce utility bills by 15-25%
Prevent unexpected breakdowns and costly emergency repairs
Ensure safe operation and protect your home from water damage
Did you know that sediment buildup is the #1 cause of premature water heater failure? Just 1/2 inch of sediment can reduce efficiency by 50% and lead to overheating, corrosion, and leaks.
| Maintenance Task | Frequency | Benefits |
|---|---|---|
| Flush tank | Every 6-12 months | Removes sediment, improves efficiency |
| Test pressure relief valve | Annually | Prevents dangerous pressure buildup |
| Replace anode rod | Every 3-5 years | Protects against rust and corrosion |
By investing a small amount of time and money into regular maintenance, you can enjoy uninterrupted access to hot water and peace of mind knowing your system is operating safely. Keep reading to learn simple DIY maintenance tips and when to call in the pros!

Warning Signs Your Hot Water System Needs Attention
Just like a car's "check engine" light, your hot water system will often exhibit warning signs when something is amiss. By keeping an eye out for these red flags, you can catch potential issues early and avoid the dreaded cold shower surprise. Here are the top signs your hot water heater needs some TLC:
1. Leaks
A puddle around your water heater is never a good sign. Whether it's due to a faulty pressure relief valve, a corroded tank, or loose connections, leaks can cause serious damage if left unchecked. Inspect your heater regularly for any signs of moisture or drips.
2. Inconsistent Water Temperature
If your once steamy shower now fluctuates between scorching and freezing, your water heater may be struggling to keep up. Inconsistent water temperature can indicate sediment buildup, a failing heating element, or a malfunctioning thermostat.
"The most common cause of inconsistent water temperature is sediment accumulation at the bottom of the tank, which creates a barrier between the burner and the water." - Jane Doe, Master Plumber
3. Discoloured or Smelly Water
If your hot water looks rusty or has an unpleasant odour, it's time to investigate. Discoloured water often means the anode rod has corroded, leaving the tank vulnerable to rust. A rotten egg smell, on the other hand, could signal bacteria growth in the tank.
4. Strange Noises
Is your water heater making a racket? Popping, banging, or rumbling sounds coming from the tank are usually caused by sediment buildup. As the sediment is heated and reheated, it hardens and causes the alarming noises.
5. Age
The average lifespan of a water heater is 8-12 years. If your unit is getting up there in age, it's more prone to breakdowns and inefficiencies. Consider replacing an older unit before it fails completely and leaves you in the cold.
If you notice any of these warning signs, don't ignore them! Addressing issues early can save you from more costly repairs down the road. Keep reading to learn some simple maintenance tasks you can do to keep your hot water flowing.

Simple Hot Water System Maintenance Tips
While it's best to leave the more technical tasks to the pros, there are some simple maintenance steps you can take to keep your hot water system running smoothly. A little TLC goes a long way in preventing costly repairs and extending the life of your unit.
Visual Inspection
Every few months, give your hot water system a quick visual check-up. Look for any signs of leaks, damage, or corrosion on the tank, valves, or pipes. If you spot anything concerning, contact the experts at Gas Safe Plumbing right away.
"An ounce of prevention is worth a gallon of hot water!" - Gas Safe Plumbing
Flush the Tank
Over time, sediment can build up in the bottom of your tank, reducing efficiency and causing wear and tear. Flush your tank every 6-12 months to keep it clean and clear.
Here's how:
Turn off the power supply (electric) or gas supply (gas systems)
Attach a garden hose to the drain valve at the bottom of the tank
Open the drain valve and let the water flow until it runs clear
Close the valve, detach the hose, and restore power/gas
Test the TPR Valve
The temperature pressure relief (TPR) valve is a crucial safety feature that prevents dangerous pressure buildup. Test it every 6 months to ensure it's working properly.
Simply lift the lever on the valve and let it snap back into place. If it doesn't release a burst of water or if it leaks afterwards, it needs to be replaced.
Insulate Pipes
Insulating your hot water pipes can improve efficiency by up to 4% and prevent heat loss as the water travels from the tank to your tap. You can find pre-cut pipe insulation at any hardware store - just slip it over the pipes and secure with tape.
Adjust the Thermostat
Most hot water systems have a thermostat that allows you to adjust the water temperature. For optimal performance and energy savings, set it to 60°C (140°F). Any higher and you risk scalding; any lower and harmful bacteria like Legionella can thrive.
By following these simple maintenance tips, you can help your hot water system run more efficiently and last longer. But remember, for anything more complex than a visual inspection or thermostat adjustment, it's always best to call in the licensed plumbers at Gas Safe Plumbing.

Professional Hot Water System Service
While some basic maintenance tasks can be done yourself, it's important to have your hot water system professionally serviced every few years. A licensed plumber will be able to thoroughly inspect your system, identify any potential issues, and perform more technical maintenance tasks.
What's Included in a Professional Service?
A major service by a licensed plumber should be done every 5 years and typically includes:
Inspecting and replacing the sacrificial anode rod if needed
The anode rod is your system's defence against rust and corrosion
Depending on your water quality, it may need replacement every 3-5 years
Cleaning or replacing valves and other components
Ensures all parts are functioning optimally and helps prevent leaks
Checking the gas supply and burner on gas systems
Proper gas flow and burner function are crucial for efficiency and safety
"Think of a professional service as a 100,000 km tune-up for your hot water system. It keeps everything running smoothly and catches small problems before they turn into big ones." - Jack Thompson, Senior Plumber
Planning for Your Service
Keep in mind that your hot water tank may need to be drained during the service, so plan accordingly. After the service, the tank will take some time to reheat the water, so you may not have hot water until the next day depending on your system.
Some telltale signs it's time to call a pro:
Your hot water is running out faster than usual
You notice strange noises coming from the tank
There are any leaks, cracks, or corrosion on the tank or valves
Your anode rod is corroded down to less than 1 cm thick
Don't wait for a small problem to turn into a cold shower! Scheduling regular professional maintenance is one of the best ways to extend the life of your hot water system and avoid unexpected breakdowns.
Safety Considerations for DIY Maintenance
While some basic DIY maintenance is good for your system, it's important to keep safety in mind. Here are a few key precautions:
Scalding Hot Water
Be cautious when flushing the tank or testing valves, as the water can be extremely hot and cause burns. Let the water cool before draining, and wear gloves and long sleeves for protection.
Gas and Carbon Monoxide
If you have a gas system, ensure proper ventilation and never attempt to work on the gas components yourself. Have a plumber check the gas supply and burner regularly, and install carbon monoxide detectors in your home for added safety.
Electrical Hazards
For electric systems, always shut off the power at the breaker before doing any work on the heater, and never attempt any electrical repairs yourself unless you are qualified.
If you're ever unsure about whether a maintenance task is safe to DIY, err on the side of caution and call a professional. No amount of savings is worth risking your safety or the integrity of your hot water system.
