How to Flush Your Water Heater
Posted on February 24th, 2017 by DLWPO
When was the last time you flushed your home water heater?
If you’re like most homeowners, your water heater is often out of sight, out of mind. However, you should flush your water heater once a year to remove the sediment that accumulates at the bottom of the tank. So, how do you perform this annual maintenance? Here are a few steps that you will want to follow.
How to Flush Your Water Heater:
- Locate your Fuse Box – before you begin the process of draining your water heater, you will first need to turn off the power running to the system. Your fuse box may be on the outside of your home or in the garage. Then, either disable the power to the electrical water heater or turn the thermostat to “Pilot” if you have a gas water heater.
- Turn Off the Water – Rotate the water shut-off valve to turn off the cold water running to your water heater.
- Open the Sink Faucet – Open the hot water sink faucet in your bathroom or kitchen. This will help prevent a vacuum from forming in your plumbing lines.
- Drain the Water – Attach a garden hose to your water heater valve (usually at the bottom of the water heater tank). Then, run the hose outside or to a bucket.
- Open the Drain – Open the water heater valve and allow the water to exit the tank. Be careful! If you are draining the water into a bucket, you will need to remember that it will be extremely hot. Let it cool before dumping it.
- Refill the Tank – Close the drain and remove the garden hose. Turn the hot water sink faucet back and turn the water supply back on. Let your tank fill. Slowly open the pressure-relief valve to get rid of any excess air.
- Bleed the Air – Open the hot water tap again to bleed any air out of the plumbing.
- Turn on the Power – Once the water heater line is back on (wait until it is running continuously), then you can turn the power back on.
