Your hot water system is one of the most essential components of a comfortable home, quietly doing its job every day—until something goes wrong. Regular maintenance can help avoid cold showers, high energy bills, and costly repairs. Whether you have a gas, electric, or solar system, keeping your unit in top condition ensures long-term efficiency and reliability. For those using gas, it’s also smart to stay informed about current natural gas rates in GA to better manage household energy expenses.
In this guide, we’ll cover easy and effective maintenance tips every homeowner can follow to keep their hot water flowing and their system running smoothly.
1. Check the Temperature Setting
Start by checking the thermostat on your water heater. Most manufacturers recommend setting it at 120 degrees Fahrenheit (49°C). This temperature is hot enough to prevent bacterial growth and provide comfortable showers while also conserving energy and reducing the risk of scalding.
If your temperature is set higher, you’re not only wasting energy, but you’re also wearing out your system faster. Lowering the temperature can extend the life of your tank and heating elements.
2. Flush the Tank Annually
Sediment build-up at the bottom of the tank can reduce efficiency and damage your unit over time. Flushing the tank at least once a year removes these mineral deposits and helps the system run more efficiently.
To flush your tank:
- Turn off the power (electric) or gas supply.
- Connect a hose to the drain valve at the bottom of the tank.
- Let the water run out completely.
- Open the cold water valve briefly to stir up remaining sediment, then drain again.
If you’re unsure how to do this, consider hiring a plumber for a quick and professional service.
3. Test the Pressure Relief Valve
The pressure relief valve is a safety feature that prevents your water heater from turning into a potential hazard. This valve automatically releases pressure if it gets too high. To test it:
- Place a bucket under the valve.
- Gently lift the valve’s handle.
- You should hear a short burst of air or see water come out.
If nothing happens, or if the valve leaks afterward, it’s time to replace it.
4. Inspect for Leaks or Corrosion
A monthly visual inspection of your water heater can help catch small problems before they become major issues. Look for:
- Water pooling around the base
- Rust spots on the tank
- Corrosion on valves or pipes
Catching a leak early can save thousands in water damage and repair costs.
5. Check the Anode Rod Every 2-3 Years
The anode rod is a sacrificial component designed to attract corrosive elements in your water, protecting the tank’s interior lining. Over time, the rod depletes and needs replacement.
To check the rod:
- Turn off the power and water supply.
- Unscrew the rod from the top of the tank.
- If it’s less than ½ inch thick or coated in calcium, replace it.
This simple step can extend your system’s lifespan by several years.
6. Insulate Pipes and the Heater
Heat loss occurs not only in the tank but also through the pipes leading away from it. Adding insulation sleeves to exposed hot water pipes helps retain heat and reduces energy costs.
Additionally, if your heater is located in a cold space like a basement or garage, consider wrapping the tank with an insulating blanket to reduce standby heat loss.
7. Schedule a Professional Inspection Annually
Even if you’re diligent about maintenance, having a licensed plumber inspect your hot water system once a year is a smart investment. A professional can detect signs of wear, test efficiency, and perform tasks that may be unsafe or difficult for the average homeowner.
This is especially important if your system is more than 8–10 years old or you notice a drop in water temperature or pressure.
Final Thoughts
Taking care of your hot water system doesn’t require a toolbox full of tools or a plumber on speed dial. With a few routine checks and some preventive care, you can significantly extend the life of your system, reduce your utility bills, and avoid unexpected cold showers.
Remember, a little attention now goes a long way in ensuring you always have the comfort and convenience of hot water when you need it.
