How to Extend the Life of Your Water Heater

Your hot water heater works hard behind the scenes every day, but like any hardworking appliance, it needs a bit of TLC to keep running smoothly. We’ve been helping homeowners across Victoria keep their hot water flowing for over 20 years. During that time, we’ve learned what actually makes a difference when it comes to maintenance.

The good news? A few simple habits can add years to your tank’s life and help you avoid those dreaded cold showers or emergency repair bills. We’ll cover what’s worth doing yourself, when it makes sense to call in help, and how to spot the warning signs that your heater might be on its last legs.

1. Schedule Annual Maintenance

Routine annual maintenance is the most effective way to prevent wear and tear and prolong the life of your water heater. Here’s what’s typically included:

Tank flushing to remove sediment that accumulates over time.
Inspection of the anode rod, which protects the tank from corrosion. Once it’s fully deteriorated, the tank is vulnerable to rust.
Testing the temperature and pressure relief (T&P) valve to ensure it’s functioning properly.
Checking for leaks, rust, and other warning signs that your tank may be near the end of its service life.

2. Consider a Water Softener (If Applicable)

If you live in an area with hard water (such as Brentwood Bay or North Saanich) a water softener can help reduce scale build-up inside your tank. This can significantly improve the efficiency and lifespan of your heater, along with other household plumbing systems.

Signs Your Hot Water Tank Is on Its Last Legs

Most standard hot water tanks last 8 to 12 years. Some signs it may be time for a replacement include:

Reduced hot water supply or water running cold sooner than expected
Rusty or discoloured water, especially from hot taps
Popping or rumbling sounds, which indicate sediment buildup
Visible rust or corrosion on the tank or fittings
Leaks or pooling water around the base of the tank

Can You Flush Your Hot Water Tank Yourself?

Yes, if your tank is in good condition and you’re comfortable with basic home maintenance. Flushing the tank annually helps prevent sediment from building up and reduces stress on your water heater.

Steps for a Basic Flush:

Turn off the power (electric) or switch the gas control to “pilot.”
Shut off the cold water supply.
Attach a garden hose to the drain valve and run the hose to a safe drainage point.
Open a hot water tap inside the home to allow air into the system.
Open the drain valve and let the water fully drain.
Briefly turn the cold water back on to stir and flush out remaining sediment.
Close everything up and restore power or relight the pilot.

If your tank is older or hasn’t been flushed in years, hardened sediment could clog valves or damage the tank lining. In these cases, it’s best to have a licensed plumber handle the job.
