The Two Step Method to Maintain a Water Heater

2/1/2021 (Permalink)

A water heater typically lasts between 8 and 12 years, but only if it is maintained properly. A simple two-step annual maintenance plan will extend the life of the water heater. If you're just going through routine servicing, there's no need to call a professional to complete the job for you. With a screwdriver and a bucket, a homeowner can usually complete servicing the water heater on their own.

Do a Partial Flush

Prevent rust and corrosion by removing sediment from the bottom of the tank. All though a complete flush of the water heater tank is best, it requires shutting down the water heater. A partial flush works well, takes a fraction of the time, and can be done while the water heater is running:

1. Place a bucket under the drain valve found near the bottom of the water heater tank.
2. Turn the valve counterclockwise to release 1 to 2 gallons of water into the bucket. Some drain valves have a handle, while others have a short stem with a slot for a flathead screwdriver.The water will be very hot, so take care to avoid burning yourself.
3. Close the valve by turning it clockwise.

If the valve won't open, contact a plumber to perform maintenance.

Test the Temperature & Pressure Valve

The temperature and pressure relief valve is a critical safety feature of your water heater.  Without an operational Temperature and Pressure value a water heater is at risk of explosion. Therefore, water heater manufacturers recommend testing the Temperature and Pressure valve once per year.

The Temperature and Pressure valve might be located at the top of the heater tank or in the side wall, and it has a discharge tube that extends down toward the base of the tank. To test the valve:

1. Place a bucket under the end of the discharge tube connected to the valve.
2. Lift up on the lever of the valve to open the valve manually. This will release hot water through the discharge tube and into the bucket.The water is very hot, so take care.
3. Let the water flow for a few seconds, then let go of the lever and allow it to snap back into place, shutting off the water. If the valve does not open and release water,? or if it leaks after the test, the valve must be replaced.
