Some believe that electric water heaters last longer and take less space inside your house. Besides, switching from gas to electrical will need a new appliance, and that means you need to turn off the gas line for the old gas water heater.
So let’s find out!
HOW TO TEE OFF AN EXISTING GAS LINE AT LOW COSTS!
Best way to how to tee off an existing gas line!
These days, many people tee off their existing water heaters by themselves. So in this guide, we will discuss exactly how to do that.
But first, you will need to arrange the materials to tee off the gas line! If you do not have the tools, you can borrow them from your friend or rent them from a shop.
If you are planning to do more projects like this in the future, then we suggest buying the set of tools listed below.
Here are some tools needed for teeing off an existing gas line:
- Pipe cutter or reciprocating saw
- A set of plumbing wrenches
- Gas-rated Teflon tape (yellow)
Here are some things to keep handy:
- If you have done plumbing work in the past, you might have a pipe cutter and plumbing wrenches lying around in your house.
- Sometimes, you may even work in tighter spaces, so keeping a reciprocating saw will help you a lot.
- Be sure to get the yellow-colored Teflon tape to use for gas fittings.
INSTRUCTIONS FOR TEEING OF AN EXISTING GAS LINE
Now that you have collected all the essential materials you need to tee off an existing gas line, then let’s begin the actual work.
Below are a couple of steps we would like you to follow:
Step 1: Turn off the gas.
You can either shut off the valve you are working on or turn off the gas meter. If you are confused, which one to pick, then we suggest you have your gas company shut it off using the meter, or you can shut it yourself.
Step 2: Let it sit.
You should wait for at least 20 minutes for the gas to scatter. You might see some vapors in the line, but don’t worry, it won’t cause any kind of explosion.
Step 3: Locate the line.
In the next step, find the line to tee off from. You may find it at a gas stove or near the water heater.
You can pick the line depending on where you want to put your new line. Usually, owners tee off one of these gas lines to a new utility or a new appliance.
Step 4: Cut the pile.
Use the reciprocating saw with a metal cutting blade or pipe cutting wrench to cut the pipe. You will need to cut 360-degree motion around the pipe.
If in case, you do not have a room, a reciprocating saw will get the job done. You can just trim downwards onto the pipe.
Make two cuts and remove the piece of pipe, which will be around a half-inch. To fulfill the task faster, we recommend you use a reciprocating saw.
Step 5: Install the socket tee.
Now, it is time to get your new gas line installed with a 90-degree three socket tee. Be sure that your tee’s size, pipe’s thickness, and the existing pipe’s thickness are the same.
Then, attach the tee with the Teflon tape.
And that’s it!
You can replace the existing line and install the new appliance. Make sure, you thread the pipe on what kind of fitting you use and also check if the tee is on correctly.
The above steps will be completed within two hours, so there is no need to take a day off from your work.
