Did you know that water tanks can loose their effectiveness over time? And did you know that you should drain your tank each year?

Most people never give their water heater a second thought — until it stops working or starts leaking. One thing you can do to extend the life of your water heater is to drain the tank annually to remove any sediment that may have built up inside it.

Tanks are purchased based on their intended life expectancy. The longer the life, the more expensive. Knowing the age of your tank can help you plan for its replacement at a time more convenient than, oh, let’s say – Thanksgiving morning! It’s a good idea to write the date of install on the tank at time of installation. Manufacturers disguise the date of manufacture within the model and serial numbers. If you need help determining the age of your heater please give me a call and I can help.

Water Heater Maintenance

To maintain efficiency, water heaters should be drained and re-filled each year to eliminate sediment build-up. Here are 4 simple steps.

Step 1: Turn off the Water Supply

If you have an electric water heater, turn off the power at the breaker-box. If yours is a gas heater, turn the thermostat to the "pilot" setting. Connect a garden hose to the drain valve located close to the thermostat, but don’t open the valve yet. Turn off the cold-water supply that feeds the water-heater usually located at the top.

Step 2: Drain the Hot Water Inside your house, open up one of the hot-water faucets in one of your sinks or tubs. This will prevent a vacuum from forming in the lines. Go back to the water-heater, and open the drain valve to drain the hot water out of the tank. Make sure the far end of the hose is draining somewhere that won’t be harmed by hot water. An outside driveway is ideal.

Step 3: Flush out the Remaining Sediment

Once the water stops flowing out of the far end of the hose, turn the water supply back on. This will flush out any remaining sediment left behind in the heater. Once the water runs clear from the end of the hose, close the DRAIN valve. Don’t forget to turn the hot-water faucet inside your house back off.

The heating element could possibly blow if there is no water in the tank. Some tanks may need to be completely full in order to prevent damage. When in doubt, always read the warnings and instructions on the tank label carefully because each tank may vary!

Step 4: Test the Pressure-Release Valve

Turn the power-supply to the water heater back on at the breaker box (or the thermostat), after the tank has filled with water. Once the water temperature has been brought back up, test the pressure-relief valve according to the manufacturer’s instructions. This safety device is designed to prevent excess pressure build-up or overheating inside the tank. If it’s faulty, you may need to have it replaced by a licensed plumber. If there isn’t a tube attached to the valve, one should be installed first to prevent injury. The discharge tube should be directed to the outside of the home or into a drain pan.
