A water heater is an essential appliance that often goes unnoticed—until something goes wrong. For new homeowners, understanding the proper care and use of your water heater can save you money, prevent breakdowns, and extend its lifespan. Here’s a quick guide on what you should and shouldn’t do to ensure your water heater operates efficiently and safely.

Do’s for Water Heater Maintenance and Usage

1. Do Flush the Tank Annually

Over time, sediment can accumulate at the bottom of your water heater tank. Flushing the tank once a year removes this buildup, improving efficiency and preventing damage.

2. Do Check the Anode Rod

The anode rod prevents rust inside the tank. Inspect it every 3-5 years and replace it when it’s more than 50% corroded.

3. Do Test the Pressure Relief Valve

The pressure relief valve is a critical safety feature that prevents dangerous pressure buildup. Test it annually to ensure it’s functioning properly.

4. Do Insulate Pipes and the Tank

Add insulation to your hot water pipes and tank (if it’s not already insulated). This reduces heat loss and lowers energy bills.

5. Do Set the Temperature Correctly

Keep the thermostat set to 120°F (49°C). This temperature prevents scalding, conserves energy, and inhibits bacterial growth.

6. Do Schedule Professional Inspections

Have a licensed plumber inspect your water heater every couple of years. They can catch potential issues before they become costly problems.

7. Do Know Where the Shutoff Valve Is

Familiarize yourself with the water heater’s shutoff valve in case of an emergency like a leak or overheating.

8. Do Consider Upgrading When Necessary

If your water heater is over 10-15 years old and showing signs of inefficiency, consider upgrading to a more energy-efficient model, such as a tankless or heat pump water heater.

Don’ts for Water Heater Maintenance and Usage

1. Don’t Ignore Strange Noises

Popping or rumbling noises could indicate sediment buildup or issues with the heating element. Address these sounds promptly to avoid damage.

2. Don’t Overlook Leaks

Even small leaks can lead to significant water damage and indicate a bigger issue. Investigate and fix leaks immediately.

3. Don’t Block the Area Around the Heater

Keep the area around your water heater clear of clutter to ensure proper ventilation and prevent fire hazards.

4. Don’t Set the Temperature Too High

Temperatures above 120°F can cause scalding injuries and waste energy. Higher settings also increase the risk of sediment buildup and tank corrosion.

5. Don’t Attempt Complex Repairs Yourself

DIY repairs may void warranties or cause further damage. For issues like faulty valves or electrical problems, always consult a professional plumber.

6. Don’t Forget to Turn Off the Power Before Maintenance

If you’re performing any maintenance, such as draining the tank, ensure the power supply (or gas line) is turned off to avoid accidents.

7. Don’t Neglect Water Quality

Hard water can cause excessive sediment buildup. If you live in a hard water area, consider installing a water softener or regularly flushing the tank.

8. Don’t Wait Until It Fails to Replace It

Water heaters often show signs of wear—like inconsistent hot water or higher energy bills—before they fail completely. Replace them proactively to avoid a sudden cold shower or flooding.

Final Thoughts

For new homeowners, taking care of your water heater doesn’t have to be complicated. By following these do’s and don’ts, you’ll ensure your appliance operates efficiently and safely for years to come. Regular maintenance, safe usage, and timely upgrades are key to getting the most out of this essential home feature.
