Your water heater works hard behind the scenes, providing warm showers, clean dishes, and hot water for laundry day. But like any appliance, it needs regular maintenance to perform efficiently and last longer. The good news? You don’t need to be a plumbing expert to keep it in top shape. With a few easy routine checks, you can extend the life of your water heater and avoid unexpected cold showers or repair bills. Here’s a simple maintenance checklist every homeowner should follow:
1. Inspect for Leaks and Corrosion
Start by doing a visual inspection of the tank and the surrounding area. Look for any signs of water pooling around the base of the heater or rust forming on the tank or pipes. Leaks can indicate failing seals or connections, while rust may signal internal corrosion; both early signs of trouble. Catching these issues early can help you fix them before they become expensive problems.
Tip: Do this check once a month, especially in older units or high-humidity areas.
2. Test the Pressure Relief Valve
The temperature and pressure relief valve is an important safety feature that releases extra pressure when the tank overheats. To test it, place a bucket under the valve, lift the lever, and let it snap back. You should hear water flow into the bucket. If nothing comes out or it keeps dripping, the valve needs to be replaced.
Tip: Test the T&P valve once a year.
3. Flush the Tank to Remove Sediment
Over time, minerals and sediment collect at the bottom of your water heater, reducing efficiency and causing damage. To flush the tank, turn off the power or set the gas control to “pilot,” then attach a hose to the drain valve and let the water flow out. Turn on the cold water briefly to rinse out any remaining sediment, then close the valve and refill the tank to keep your heater running smoothly.
Tip: Flush the tank at least once a year. Do it twice if your water is particularly hard or if you use a heat pump system alongside the heater.
4. Check the Anode Rod
The anode rod protects your water heater from rust by attracting minerals that cause corrosion. Over time, it wears out and should be checked regularly. Turn off the power and water supply, drain a few gallons, then remove the rod. If it’s thinner than ½ inch or covered in calcium, replace it to keep your tank in good condition.
Tip: Inspect the anode rod every 2–3 years.
5. Adjust the Temperature Setting
Setting your water heater temperature too high can waste energy and put extra strain on the system. For the best balance of comfort and efficiency, keep it at 120°F (49°C). To adjust the temperature, locate the thermostat dial, turn it to 120°F, and secure the panel back in place.
Tip: Check the setting every few months, especially after power outages.
Conclusion
Regular water heater maintenance isn’t just about preventing breakdowns; it’s about maximising efficiency, saving money, and getting the most life out of your investment. These simple routine checks can help you avoid major repairs and extend your water heater’s life by several years.
