Replace Gas Water Heater or Fix It?


Replace the gas water heater? Maybe not.

There are some things you can do to fix a water heater if you are having problems. However, there some situations where you will need to replace the gas water heater.

One prime reason would be that the tank itself is actually leaking. If the tank is leaking, more than likely there is a hole in the water heater, itself. It wouldn’t make sense to patch the hole, because it is probably due to a rusted tank.

If there is no leak, but you are having problems, it might be that you need to get a different system or simply want to get a new one.

Before you replace the gas water heater, you will need to take a few steps. First of all, you need to turn off the gas. This can be accomplished by turning off the main gas supply and then the valve to the heater. You will know the gas is off when the pilot light goes out.

If you do not have a way to turn off the gas, simply call your gas company. Most of the time the gas company will send someone out to turn off the gas if you tell them you are trying to replace the gas water heater.

You now want to drain the water out of your tank. Simply hook a hose up to the drain valve and let it drain. Make sure that you open the hot water faucet in the house to let the air properly vent from the tank and lines. Once the water is out you can remove the heater from the pipes with a saw or unscrew them if they are screwed together. The last thing to do is to disconnect the flue and remove the heater.

Installation is in the opposite order. Install the heater into its location and then replace the flue. Reattach the lines, and turn the water and gas on. Do not forget to close the bottom drain valve when refilling your tank.

If you had to have the gas company come out to turn off the gas, you may want to install a gas valve in the line, so that the gas company won’t have to come back the next time you want to replace the gas water heater.
