Gas Line Leak! How I Safely Re Piped My Furnace Gas Line Step By Step

What happens here

Assemble the drip leg by first applying Megaloc pipe dope to a close nipple and threading it into the main gas supply line fitting. Next, apply pipe dope to the threads of a T-fitting and thread it onto the nipple. Ensure the T-fitting is positioned correctly to allow for a vertical extension downwards (the drip leg). Finally, apply pipe dope to another nipple and thread it into the bottom of the T-fitting. The drip leg should be a minimum of 3 inches long to effectively collect sediment. Use adjustable pliers to securely tighten all connections.

Goal: Assemble and install a new drip leg, consisting of a close nipple and a T-fitting, onto the main gas supply line to collect sediment and moisture.
