If you need to change your gas line, then you have to figure out which size connectors you’ll need. The measurements are taken from the diameter on the inside. You’ll also need a T2 pipe joint type compound and some elbow connectors plus a T connector. Most of the time, you will only be adding a few lines per time during a Gas Line Installation. Be sure to get measurements for the lines you plan on buying. If you are going to be using the flexible PVC lines then you don’t have to be exact, but with steel you will not have a lot of leeway.
For any Gas Line Installation, it’s crucial that you disconnect the current gas line. You need to allow the gas to drain out of the line before you do anything. All it takes is for you to use a pipe wrench to turn the line’s valve a quarter turn. It will be off when the two holes are lining up with one another. Once the gas is completely off, you will open the connection near where you’re going to work. Gas is going to slowly flow out, so you should keep our distance to prevent inhaling a lot of gas.
Next, you are going to install a spitter. This requires you to take out the older section and put the new one on. Use the joint compound on the male ends of each side of the new connection. This will end up holding the line together to prevent gas from leaking out. With the spitter in place, you will be ready to branch off to the new Gas Line Installation. Make sure to do the same thing you did when you put in the spitter. Installing a shutoff valve is the next step, and it is done the same way the connections were.
After finishing your Gas Line Installation, you are going to want to test it out. Mix water and dish washing soap together and rub them over your new connections. Turn the gas back on, and look to see if any bubbles form near your work. If they did, you need more joint compound. If there are no bubbles, you are finished.
