I think Tom may have suggested unions on both sides of the tank T...For leak, I'd cut in a union, not a couple into the pipe. Then redo the leaking parts up to the union. With the union you'll be able to tighten or remove the tank or retighten fittings as needed.
I can't tell exactly where the leak is - where the PVC female adapter screws on the brass fitting?That will require me to cut the PVC which I didn't want to do, but that's a good idea - a little pain now for a lot less pain later! Thanks for the suggestion!
It should have them on both side of the tank, it helps with a problem like this. Since I've been using PEX with lead free brass fittings and barbed valves it solves issues like this, much ez'er to repair and modify the system in the future.I think Tom may have suggested unions on both sides of the tank T...
If you had them both sides, you could disconnect the entire bladder tank assembly.
I can't speak for Tom, but when he said "tighten or remove the tank," that'd be the way accomplish it.
It's a hassle to do both sides, but "Cry now, or cry later......"
Tom- - I hope I interpreted it correctly......
