General Maintenance For Your Water Heater
Your water heater works hard every day to provide hot water for showers, dishes, laundry, and more. But like any major appliance, it needs regular maintenance to run efficiently and last as long as possible. Most tank water heaters have a lifespan of 8 to 12 years, but neglecting maintenance can shorten that significantly and lead to unexpected breakdowns or even water damage in your home.
At Conner Plumbing, we help homeowners throughout Irmo, Chapin, Lexington, Columbia, Cayce, and West Columbia, SC keep their water heaters in top condition. Here are the key maintenance tasks every homeowner should know about.
Flush the Tank Annually
Over time, sediment from minerals in your water supply settles at the bottom of your water heater tank. This sediment buildup reduces heating efficiency, makes the unit work harder, and can cause strange popping or rumbling noises. Flushing the tank once a year removes this sediment and helps your water heater heat water more efficiently. If you are not comfortable doing this yourself, a professional plumber can handle it quickly during a routine maintenance visit.
Check the Anode Rod
The anode rod is a metal rod inside your water heater tank that attracts corrosive elements in the water, protecting the tank itself from rusting. Over time, the anode rod corrodes and needs to be replaced. Most manufacturers recommend checking it every two to three years. If the rod is heavily corroded or less than half an inch thick, it is time for a replacement. This inexpensive part can add years to the life of your water heater.
Test the Temperature and Pressure Relief Valve
The temperature and pressure (T&P) relief valve is a critical safety feature on your water heater. It releases water if the temperature or pressure inside the tank gets too high, preventing a dangerous situation. To test it, lift the valve lever briefly and let it snap back. You should hear a gurgling sound as water is released into the drain tube. If the valve does not release water or continues to drip after testing, it may need to be replaced by a licensed plumber.
Set the Right Temperature
Many water heaters come from the factory set at 140 degrees Fahrenheit, but the Department of Energy recommends setting it to 120 degrees. This temperature is hot enough for household needs while reducing the risk of scalding, slowing mineral buildup, and saving energy. Lowering the temperature by just 10 degrees can reduce your water heating costs by 3 to 5 percent.
Inspect for Leaks and Corrosion
Take a few minutes every couple of months to visually inspect your water heater. Look for any signs of water pooling around the base, rust on the tank or connections, or moisture on the pipes leading to and from the unit. Catching a small leak early can prevent major water damage. If you notice corrosion on the tank itself, that is usually a sign the unit is nearing the end of its life and may need to be replaced soon.
Insulate Older Water Heaters
If your water heater is an older model, adding an insulation blanket can help reduce heat loss and improve energy efficiency. You can also insulate the first few feet of the hot water pipes coming out of the unit to keep the water hotter as it travels to your faucets. This is a simple, affordable upgrade that can lower your energy bills.
Schedule Professional Maintenance
While there are some maintenance tasks you can handle yourself, an annual professional inspection ensures nothing is overlooked. A licensed plumber will check all components, flush the tank, test the safety valve, inspect the gas line or electrical connections, and alert you to any issues that could lead to problems down the road. Think of it as an investment that protects your water heater and your home.

Frequently Asked Questions
How often should I have my water heater serviced?
We recommend a professional inspection and tank flush once a year. If you have hard water, you may benefit from flushing the tank every six months to prevent excessive sediment buildup.
How do I know when my water heater needs to be replaced?
Common signs include rusty water coming from the hot side, frequent repairs, water pooling around the base, inconsistent hot water, and the unit being more than 10 years old. If you are experiencing any of these issues, it may be more cost-effective to replace the unit rather than continue repairing it.
Can I do water heater maintenance myself?
Some tasks like checking the temperature setting and visually inspecting for leaks are easy to do yourself. However, flushing the tank, testing the T&P valve, and checking the anode rod are best handled by a professional to ensure they are done safely and correctly.
