Level Up Your Water Heater: Why It Matters and How to Do It Right

When installing a water heater, ensuring its level is crucial for its proper functioning and longevity. An unlevel water heater can lead to a range of issues, including reduced efficiency, premature failure, and even safety hazards.

Why Is Leveling a Water Heater Important?

• Sediment Accumulation: Sediment naturally settles at the bottom of the water heater tank. If the heater is not level, sediment can accumulate unevenly, causing overheating and reduced efficiency.
• Gas Valve Malfunction: Gas water heaters rely on a gas valve to control the flow of fuel. If the heater is unlevel, the valve may not operate correctly, leading to gas leaks or ignition problems.
• Premature Failure: An unlevel water heater can put excess stress on its components, including the tank, heating element, and piping. This can lead to premature failure and costly repairs.
• Safety Hazards: In extreme cases, an unlevel water heater can cause the tank to rupture or leak, creating a potential safety hazard.

How to Level a Water Heater

Leveling a water heater is a relatively simple process that can be completed in a few steps:

1. Disconnect the Power/Gas Supply: Turn off the electricity or gas supply to the water heater.
2. Remove the Water Heater: Carefully remove the water heater from its existing location.
3. Place Shims Underneath: Use shims (flat pieces of material) to level the base of the water heater. Adjust the shims until the unit is level in both directions.
4. Reinstall the Water Heater: Carefully lift the water heater back into place and secure it to the floor.
5. Reconnect the Power/Gas Supply: Reconnect the electricity or gas supply to the water heater.

Checking the Level

Once the water heater is installed, it’s essential to check its level using a spirit level:

• Place the spirit level on the top of the water heater tank, parallel to the front edge.
• If the bubble is not centered, adjust the shims accordingly.
• Repeat the process for the side of the tank, ensuring it is also level.

Consequences of an Unlevel Water Heater

• Reduced Efficiency: An unlevel water heater can cause uneven heating, leading to increased energy consumption and higher utility bills.
• Shorter Lifespan: The stress on components due to uneven weight distribution can shorten the lifespan of the water heater.
• Increased Maintenance: Unlevel water heaters require more frequent maintenance, including sediment removal and component inspections.
• Safety Concerns: A severe unlevel condition can create safety hazards, such as gas leaks or tank ruptures.

Tips for Maintaining a Level Water Heater

• Regularly Check the Level: Use a spirit level to check the water heater’s level at least once a year.
• Adjust Shims as Needed: If the water heater has shifted or settled over time, adjust the shims to maintain levelness.
• Avoid Overloading: Do not place heavy objects on top of the water heater, as this can affect its level and stability.
• Contact a Professional: If you experience any difficulties leveling the water heater or suspect it is unlevel, contact a qualified plumber for assistance.
