Your water heater provides hot water for daily tasks like cooking, cleaning, and bathing so it is important to regularly maintenance the appliance to extend its lifespan. And while it’s important to have your water heater serviced by a professional, it’s equally important that you maintain the upkeep to reduce the chances of a major repair.
Flush Your Water Heater Tank Annually
Create a reminder on your digital or paper calendar to flush your water heater tank once a year—this will also serve as your reminder to perform other water heater maintenance. An annual flush removes the sediment from the bottom of the tank and prevents corrosion. Over time, sediment build up will cause your water heater to operate less efficiently.
To drain your water heater, you’ll:
- Shut off the power or gas to the unit.
- Attach a hose to the drain valve.
- Open the valve and allow the water to drain until it runs clear.
- Refill the tank and turn the power or gas back on.
It is imperative that you never turn on a water heater when it is empty.
Insulate the Tank
Having an insulated tank eliminates the strain on a unit because it prevents it from having to work harder to heat the water and in turn maximizes the longevity and efficiency of the water heater. A standard water heater can last 8-12 years; however, modern units that are routinely maintained can last 20 years or more.
Insulating the Pipes
You should insulate the pipes that lead to and from the unit so the water stays hot as it travels through the pipes—this will also reduce energy costs. In the winter time, insulated pipes are less likely to freeze and burst.
Lower Temperature
You can save energy and prolong the life of your water heater by turning down the temperature. Water heaters can reach temps of 140 degrees, which can be dangerous if you have young children or elderly residents in your home. The recommended setting is 120 degrees for a balance of safety and bacteria prevention.
TPR: Temperature Pressure Relief Valve
The TPR is a safety feature on a hot water heater that prevents possible explosions by automatically releasing hot water or steam that exceeds 210 degrees. It is important to test it annually. The valve should last as long as your water heater. To test, you’ll want to walk through these steps:
- Lift the lever on the valve and let some water out.
- If the water doesn’t come out or if a large amount of water comes out, the valve needs to be replaced. It is important to contact a professional due to gas and water safety precautions.
- If the water comes out and then stops once you lower the valve, your TPR is working fine.
Anode Rod
The anode rod is a steel wire wrapped in aluminum, magnesium, or zinc that protects the tank from rust and corrosion. It’s a vital piece that should be inspected every year. You can inspect by removing it from the tank and inspecting for corrosion. Typically, a rod should be replaced every two to five years. You’ll check to see if 25 percent or less of the rod is corroded, or if the water is discolored or foul smelling. Some professionals will recommend changing the rod once 50 percent is corroded if there isn’t a discoloration or smell. Neglecting the anode rod can potentially void your warranty or cause future property damage.
Air Intake Filter
Check the manufacturer guide to learn your hot water heater’s suggested filter maintenance. The majority of filters suggest cleaning or replacing your air intake filter every six to twelve months depending on the dust levels and usage. A clean filter will prevent overheating or unit shut down. Signs that your filter needs attention could look like:
- Dirt or debris on the filter.
- Reduced hot water flow or pressure.
- Odd noises coming from the unit.
Professional Inspection
Regular professional maintenance and inspections are crucial to prevent major problems and lengthen the life of your water heater. A trained and certified professional will be able to identify potential problems and repair minor issues on the spot.
