Step-by-Step Guide for Installing a Tankless Water Heater in Austin, Texas

Installing a tankless water heater requires certain steps to be done in the correct order. A careful installation job will prevent expensive repairs in the future, as well as make sure the heater works efficiently.

1. Select the proper location

Choosing the proper location for your tankless water heater is one of the most important elements of a successful installation. Before you purchase one, make sure to measure the area where you want it installed. You’ll also need to determine the best spot that offers easy access to a gas line, water pipes, and a drain.

2. Install the necessary pipes

Once you’ve determined your chosen location, you’ll need to install all necessary pipes. This will involve running copper pipes from the water and gas sources to the heater location. You should also make sure to insulate the pipes in order to protect them from freezing, as well as corrosion.

3. Hang the tankless water heater

Once all necessary pipes are installed, you can hang the tankless water heater. It’s recommended that you use a Flash Seal or other type of support bracket to hang the heater, as this will help ensure it stays secure.

4. Install the safety valve

Installing a safety valve helps protect your property from potential damage due to gas or water leaks. It normally takes just a few minutes to install the safety valve at the designated spot.

5. Connect the necessary pipes

The next step is connecting the necessary pipes to the tankless water heater. It’s important to make sure you’re using the correct tubing, pipe sealant, and Teflon tape.

6. Test the installation

Once all necessary pipes and connection points have been securely fitted, it’s time to test the installation. This involves running the water supply line in order to make sure everything is functioning properly. If your heater is connected to a gas line, you should also turn the gas on and make sure there are no leaks.
