    Take a bucket and there is a faucet at the bottom of water heater and open it up and let it run until there is clear water rust settles at bottom of tank if you have a gas water heater you may have to turn the temperature up a few notches? above the warm notch. You do not want it to hot where it feels to hot it may take a couple of days till you get it right where you like it should be around 120 degrees? the best way to check it is let it run for about 2 minutes in a measuring cup then check the temp with a thermometer.

  • Water heaters have a plate or sticker on them when they were manufactured. Here are some sites to help you out.

    Mine have all conked out with no warning, but I knew it was inevitable. Since I live alone, I have been lucky as they have all lasted far past their life expectancy. And I know how to replace myself. I just have to borrow or rent a truck to get the new one home.

      Did you notice any drops of water under tank base, or at top, where attached to water supply lines? Some tanks last only 7 years, while others can last more than 20, if the tank has been drained, yearly, and the anode rod replaced every 7 years.

      If you're lucky, you reside where installation by a registered plumber is not required, and new tank doesn't require a pressure release tank. New ones in PA., including installation cost between $950.00-$1050.00 and up, for a 40 gallon tank.
