Water Heater Maintenance and Flushing
Annual flushing and an anode check are the keys to a long-lived, efficient water heater.
Simple annual maintenance keeps your water heater efficient, quiet and longer-lasting — especially in hard-water areas.
Annual flushing
Draining a few litres (or fully flushing) removes sediment that causes rumbling, lost efficiency and tank wear. Hard-water homes benefit most from yearly flushing.
Other checks
Inspect the anode rod every few years, test the T&P valve, check for leaks and corrosion, and confirm the temperature setting and venting (gas) are correct.
Key takeaways
- Flush yearly to remove sediment
- Check the anode rod every 2–3 years
- Test the T&P valve
- Inspect for leaks and corrosion
