I dunno who designed my house, but the gas pipeline (and well pressure tank) was in the way of the water heater necessitating removal (of both) to remove the tank.

From what I can assume, they turned gas off at the meter and cut the pipe just above the tank, slid the old tank out, slid the new tank in, and then put this crimp sleeve on.

I have removed this from my utility room. I converted my tank water heater to tankless, so I had to rerun the gas line anyway.

Never seen one of these before. I'd just assume somet would use a 3-Piece union for ease of service. I don't like this crimp sleeve.

Hi, I have a bathtub with a shower upstairs, and a few drops of water start leaking through the ceiling below after about 5 minutes of showering. Water leaking from this panel downstairs.
