Welcome to our blog!
We want you to be an informed homebuyer, and each blog post is a question that we have answered for our friends and customers over the years. Hope they help you make a good choice for your next home.

  1. 3)Close the valve on the cold water supply pipe of the water heater, to shut off the water flow to the tank.

  2. 4)Open a hot water faucet at a nearby sink. This will allow air flow backwards into the tank so that it will drain easier.

  3. 5)Open the hose faucet valve and let the tank drain completely.

  4. 6)Close the hose faucet and let the tank refill, leaving the sink faucet open for a while. You will get a sputtering mixture of water and the air that is being pushed back out of the tank for a while. When the water runs continuously at the sink, without any sputtering, shut off the sink faucet and close the hose faucet.

  5. 7)Turn up the thermostat on the gas water heater, or switch on the breaker at an electric water heater, put the hose away, and you are done.

  6. 8)If the hose faucet drips and does not close completely, there is likely some sediment residue stuck in the valve. You may have to repeat the flushing operation one more time.

   It’s a sensible maintenance idea to drain your water heater every two years, which will both prevent the annoying sounds and extend the life of the tank. If the flushing operation is more than you want to tackle, a professional plumber can do the job for you, along with a doing a general maintenance check to make sure there are no other problems.

While we hope you find this series of articles about home inspection helpful, they should not be considered an alternative to an actual home inspection by a local inspector. Also, construction standards vary in different parts of the country and it is possible that important issues related to your area may not be covered here.
