As you can see, the two lock nuts on the regulator has enough clearance and (assuming they aren’t completely frozen), should be allow the regulator to be removed.
The concerning part is the bottom elbows. Yes, there appears to be two of them.
Any change of attack? I think the bottom part of the drywall needs to be removed. It’s probably going to get destroyed anyway with any sort of heat to the pipe…
I’m thinking maybe remove both elbows at the bottom and just have a clean pipe running up from the ground to work with…
I also measured the pressure on my pipes. It looks to be around 80-82 PSI…Ouch…I guess it’s been that way for awhile now…
