At Ernie’s Plumbing, we’ve helped homeowners throughout Arlington and Dallas keep their water heaters running efficiently for years longer than expected by following a few key maintenance practices. A little upkeep goes a long way when it comes to protecting your investment and avoiding unexpected breakdowns. Whether you have a traditional tank unit or a tankless system, these water heater maintenance tips for Dallas, TX homeowners can help you extend water heater life in Texas homes and avoid costly replacements.
1. Flush the Tank Annually
Sediment buildup is one of the most common causes of premature water heater failure, especially in Texas, where hard water is common. Minerals like calcium and magnesium settle at the bottom of the tank over time, creating a barrier between the burner and the water. This reduces efficiency and puts extra strain on the system.
Tip: Drain and flush your tank at least once a year. This clears out sediment and helps your unit heat water more effectively. If you’re unsure how to do this, our team at Ernie’s Plumbing can take care of it during a routine maintenance visit.
2. Test the Temperature & Pressure Relief Valve
The temperature and pressure (T&P) relief valve is a critical safety feature. It’s designed to release water if the tank becomes too hot or the pressure gets too high. If this valve malfunctions, it can put your home at risk.
Tip: Test the T&P valve once a year by lifting the lever to ensure water flows out and then letting it snap back. If water doesn’t flow or the valve continues to leak afterward, it needs to be replaced.
3. Check the Anode Rod
The anode rod is a metal rod inside your water heater that attracts corrosive minerals, protecting the tank from rust. Over time, the rod itself corrodes and stops doing its job, allowing the tank to rust from the inside out.
Tip: Have the anode rod inspected every 2–3 years. If it’s heavily corroded, replacing it can significantly extend water heater life in Texas homes by preventing internal damage.
4. Insulate the Tank and Pipes
If your water heater is located in a garage, attic, or unheated area, it’s working harder during colder months. Insulating the tank and the first few feet of the hot water pipes helps retain heat and reduces energy consumption.
Tip: Use a water heater insulation blanket and foam pipe sleeves. Just make sure not to cover the thermostat or the top of a gas unit. Our professionals can help insulate your system correctly during service.
5. Keep the Temperature at the Right Setting
Setting your water heater too high can increase wear on the tank and waste energy. Most manufacturers recommend a setting of 120°F for both safety and efficiency.
Tip: Check your thermostat and adjust the temperature if needed. Lower settings also reduce the risk of scalding and save on energy bills.
6. Schedule Annual Professional Maintenance
Many homeowners wait until their water heater fails to call a plumber. But annual maintenance can catch small issues—like worn parts, small leaks, or pressure problems—before they turn into major repairs or replacements.
Tip: Schedule an annual checkup with Ernie’s Plumbing. Our water heater specialists will inspect all components, flush the tank, check for corrosion, and ensure your system is running efficiently.
