Learn How to Service Your Unit in Austin & Hays County

There is nothing worse than discovering those nice, hot showers you are used to taking aren’t so hot anymore. Yup, it’s time for water heater service. Maybe it has sprung a leak or it’s just stopped working. Well, it might be time for you to replace or repair your water heater.

Removal of Water Heater

  • Turn off the gas using the cut-off valve. This is a VERY important step
  • Turn off the water supply and turn on all the hot water faucets in the house
  • Use a garden hose to drain the tank completely.
  • Pipes will be hard-plumbed which requires cutting the line, or connection with the water heater connector hoses in some cases you can simply unscrew the connection
  • Disconnect the pipes and remove the water heater. They can be heavy, so get a helper and be careful


  • Put the water heater in place and connect the pipes
  • Add connector hoses if your old water heater didn’t have them
  • Make sure the hot water faucets are still open and turn on the water supply. This keeps air from getting trapped in the water lines
  • Let the water flow from each faucet for one minute before turning them off
  • Reconnect the wires, turn on the power and wait for the water to heat up

TIP: Routine Maintenance – The best thing for a happy water heater is water heater service.
