    Default Seized gas pipe

    Hi. I want to extend my black iron gas piping for a new water heater and gas grill. My pipe is 1-1/4 and has a plug at the end of the line that I simply cannot loosen. It's only a few years old, but the sealant the guy used is black, and has hardened. I thought the idea behind pipe sealant was it's supposed to be able to be worked with later. The stuff I'm using says it's non-hardening. Any ideas how I can get this plug out to continue my run would be appreciated.

    It can take a surprising amount of torque to loosen a fitting. Make sure to help hold the fitting with another wrench while removing the plug. You might need two people and an extension to the wrench.

    You had that right. I slipped 3' of pipe over my wrenches and it came loose. Thanks again.
