Water Heater Maintenance Tips: Ensuring Hot Water When You Need It Sep 24, 2025

Maintaining your water heater is essential for ensuring that you have hot water whenever you need it, especially during those chilly winter months. Neglecting regular water heater maintenance could lead to numerous issues, including inefficient heating, higher energy bills, and even costly repairs or replacements. At HMC Plumbing, we understand how vital an efficient water heater is for your home, and we are committed to helping you keep it in top condition with these practical water heater maintenance tips.

First and foremost, it’s crucial to regularly inspect your water heater for signs of wear and tear. This includes checking for leaks, rust, or any strange noises that might indicate a problem. Early detection of these issues can save you time and prevent costly repairs. By performing visual inspections, you can also ensure there aren’t any visible signs of corrosion or mineral buildup, commonly seen around the tank and fittings. Addressing these issues early can often prevent more severe damage down the road.

Another important step in maintaining your water heater is flushing the tank at least once a year. Over time, sediment and minerals from the water supply accumulate at the bottom of the water heater tank, making it less efficient. This sediment can cause the heater to use more energy as it attempts to heat the water, which can lead to higher utility bills. To prevent this, turn off the power or gas supply to the unit, then attach a hose to the tank drain valve. Let the water drain out completely, removing all the sediment. This process not only improves efficiency but also extends the life of your heater.

Adjusting the thermostat settings can also enhance the efficiency of your water heater. Most manufacturers set the thermostat at 140 degrees Fahrenheit, but lowering this setting can save energy and reduce the risk of scalding. The U.S. Department of Energy suggests setting the thermostat to 120 degrees for optimal performance and safety. This simple adjustment can result in significant energy savings over time.

Inspecting the anode rod is another essential maintenance task. The anode rod protects your water heater from rust and corrosion by attracting minerals and metals that would otherwise damage the tank. If the anode rod is heavily corroded or worn down to less than half an inch in thickness, it’s time to replace it. This affordable component plays a critical role in extending the overall lifespan of your water heater.

Lastly, if you find that these maintenance tasks are becoming too frequent or if your water heater is over a decade old, it might be wise to consult with a professional plumber from HMC Plumbing. Our experienced technicians can assess whether it's more cost-effective to repair your existing unit or invest in a new, energy-efficient model.

By taking the time to maintain your water heater, you can ensure a steady supply of hot water, reduce energy consumption, and prevent unexpected breakdowns. HMC Plumbing is committed to providing expert advice and services to help you keep your water heater running smoothly. Don’t wait for problems to arise—schedule regular maintenance and enjoy the peace of mind that comes from knowing your water heater is in good hands.
