If you are working in your basement in Chesterfield, MO and you notice that your water heater is making screeching or crackling sounds, you may worry that you have to replace your heater. There are some situations where that is the case, but fortunately there are many other times when you just need to give your heater a little extra care. Routine maintenance is important to keep potential problems at bay.

Flushing Your Water Heater

One of the easiest ways to keep your heater working properly is to perform a water heater flush once a year. You will need a garden hose, a regular screwdriver and a drainage area to capture the water. Following a few easy steps will help to prevent any sediment from building up inside the heater and will keep it running smoothly.

Turn off the Heater – For gas heaters, make sure the pilot light is off. Electric heaters need to be turned off at the circuit breaker.
Attach Hose – The garden hose must be connected to the drain valve. The other end of the hose should be placed in an area that can capture water and sediment. Wearing gloves is a smart idea.
Drain the Water Tank – The drain valve must be opened to allow the water to flow out. Allow several minutes to ensure the tank is empty. To help the water drain more quickly, it’s a smart idea to turn on a hot water faucet somewhere else in the house. Then turn off the valve on the water supply.
Close the Valves – After you are sure that the water and sediment have been drained, close the valves. You can then turn on the water supply.
Restore Power and Turn on Heating Element – When you are satisfied that the tank is full, turn the power back on. Then turn the heating element on.

Performing a flush of your water heater every year should keep it running well for many years.
