You guys reminded me of that leak I had on my A7..
http://ecorenovator.org/forum/geothe...heater-33.html
I just picked up another 1-peice fitting (3/4" iron pipe to PEX adapter. ID=0.533").
Here's the two piece
'Swivel' that I replaced.. (Also comes in 1")
SharkBite 3/4 in. PEX Brass Female Swivel Adapter-UC530A at The Home Depot
I wonder if something like this could be used? Make a brass slug with
two holes for the copper tubes and braze the whole thing in place.?.
Add a brass nipple to screw into the tank..
If the tubes were too large, maybe the 1" adapter could be used?
And it that was still too small, maybe the ID could be bored out a bit..
