Your water heater works hard every day to provide hot water for your showers, dishes, and laundry. Over time, sediment builds up inside the tank. This sediment is mostly minerals from the water that settle at the bottom. When this happens, your water heater has to work harder, uses more energy, and might break down sooner.

What Happens When Sediment Builds Up

Sediment at the bottom of your water heater causes several problems. First, it makes a barrier between the heating element and the water. This means your heater needs more energy to warm your water. Your energy bills go up, and you might run out of hot water faster.

The sediment can also damage the inside of your tank. When water gets trapped under the sediment layer, it can overheat and cause the metal to become brittle. This might lead to leaks or even tank failure.

If you hear popping or rumbling sounds from your water heater, that's often a sign of sediment build-up. The noise happens when water bubbles up through the sediment layer.

When to Flush Your Water Heater

You should flush your water heater at least once every year. If you have hard water (water with lots of minerals), you might need to do it more often. Some experts recommend flushing every six months in areas with very hard water.

If you're not sure when your water heater was last flushed, it's probably a good time to do it. For older water heaters that have never been flushed, you might want to call for professional water heater repair in Jacksonville. Sometimes old sediment can be very hard to remove and might need special tools.

Tools You'll Need

Before you start, gather these items:

  • A garden hose long enough to reach from your water heater to outside
  • A bucket
  • A pair of work gloves
  • A flathead screwdriver

Step-by-Step Guide to Flush Your Water Heater

  1. Turn Off the Power or Gas

Safety comes first! For electric water heaters, turn off the power at your breaker box. For gas water heaters, set the gas valve to the "pilot" position.

  1. Turn Off the Cold-Water Supply

Find the cold-water valve on the pipe that goes into the top of your water heater. Turn it clockwise until it stops.

  1. Let the Water Cool

Wait for about 30-60 minutes. This helps prevent burns when you drain the tank.

  1. Connect Your Garden Hose

Find the drain valve of your water heater. It looks like an outdoor faucet. Connect your garden hose to this valve. Put the other end of the hose outside or in a floor drain.

  1. Open a Hot Water Faucet

Go to the closest sink and turn on the hot water. This prevents a vacuum from forming in the pipes.

  1. Open the Drain Valve

Use your screwdriver to open the drain valve on your water heater. Water will flow out through the hose. At first, it might look rusty or dirty. This is normal.

  1. Flush Until Clear

Let the water flow until it runs clear. This means most of the sediment is gone. If your water heater is very dirty, you might need to repeat the draining process.

  1. Close the Drain Valve

Close the drain valve, when the water runs clear.

  1. Refill the Tank

Close the hot water faucet in your sink. Open the cold-water supply valve to start refilling the tank.

  1. Restore Power or Gas

Once the tank is full, turn the power back on at the breaker box or turn the gas valve back to the "on" position.
