Griffin Plumbing Services Water Heater Annual Checkup Checklist

1. Check the Age of the Water Heater

   Locate the serial number on the manufacturer’s label to determine the age of your water heater. If it’s over 8-12 years old for a traditional tank model, or 15-20 years for a tankless unit, it may be time to consider a replacement.

2. Look for Leaks

   Carefully inspect the area around the water heater, including the base and all connections, for any signs of leaks or moisture. Even a small leak can lead to bigger problems and potential water damage.

3. Check the Pressure Relief Valve (TPR Valve)

   The Temperature Pressure Relief (TPR) valve is a safety feature that releases excess pressure. Test it by lifting the lever to ensure it releases water. If it doesn’t, it may be faulty and need replacement.

4. Examine the Inlet and Outlet Connections

   Check the cold and hot water connections on top of the water heater for any signs of corrosion, rust, or leaks. Tighten or replace connections as necessary.

5. Flush the Tank (for Traditional Tank Heaters)

   Sediment can build up at the bottom of the tank, reducing efficiency and causing damage. Flush the tank to remove sediment and ensure optimal performance. For tankless models, a descaling flush should be performed to clear mineral buildup.

6. Check for Rust or Corrosion on the Exterior

   Visually inspect the exterior of the water heater for any signs of rust, corrosion, or discoloration. If the outer casing is rusting, it could indicate internal damage.

7. Inspect the Heating Element (Electric Heaters)

   If you have an electric water heater, test the heating elements to ensure they’re functioning properly. A failing element can lead to inconsistent water temperature.

8. Check the Thermostat Settings

   The recommended temperature setting is 120°F to prevent scalding and reduce energy use. Adjust the thermostat if necessary and ensure that it’s maintaining a consistent temperature.

9. Inspect the Expansion Tank (if applicable)

   If your system has an expansion tank, check the pressure with a tire gauge to ensure it matches the water pressure in your system. Tap the tank lightly—if it sounds full, it may need to be drained or replaced.

10. Look for Strange Noises

    Listen for any unusual sounds, such as popping or hissing. These noises can indicate sediment buildup, air pockets, or other issues that need attention.

11. Check the Venting System (Gas Heaters)

    For gas water heaters, inspect the venting system to ensure there are no obstructions or leaks. Improper venting can lead to dangerous carbon monoxide buildup.

12. Test the Pilot Light (Gas Heaters)

    Make sure the pilot light is lit and functioning correctly. If it’s weak or keeps going out, the thermocouple may need replacement.

13. Look for Signs of Water Discoloration

    Check the water quality coming from the heater. Rusty or discolored water can indicate an issue with the tank lining or corrosion.

14. Inspect the Burner (Gas Heaters)

    Remove the burner access panel and inspect for any dust or debris. A clean burner will help maintain the efficiency and safety of your heater.

15. Check for Proper Clearance

    Ensure there is enough clearance around the water heater (at least 2 feet for traditional tanks) for proper airflow and maintenance access.

16. Monitor for Smells

    Any sulfur or “rotten egg” smell may indicate bacteria buildup or a failing anode rod. This often requires a professional flush and treatment.

17. Ensure Proper Water Pressure

    Test the water pressure coming out of the hot water lines. High water pressure (over 80 psi) can damage your system and create leaks.

18. Examine Insulation (for Efficiency)

    If your water heater is in an unheated area, check the insulation on the pipes and around the tank. Adding insulation can improve energy efficiency and reduce standby heat loss.

19. Check for Gas Leaks (Gas Heaters)

    Use a gas leak detector or apply a soap solution to the gas line connections and look for bubbles. If you detect a leak, shut off the gas and call a professional immediately.

20. Install a Water Alarm Nearby

    A water alarm can alert you to leaks before they cause serious damage. Place it at the base of your water heater to catch any early signs of leaks or water buildup.

21. Install a Carbon Monoxide Detector Nearby (for Gas Heaters)

    Gas water heaters can emit carbon monoxide if venting is compromised. Installing a carbon monoxide detector near the heater can help keep your family safe from this odorless, dangerous gas.
