As a side note, check that double-tee. Mine was exceptionally old/brittle and one of the nipples cracked off with hardly any effort. They are naturally "NLA" - you'll need to rig up a replacement using brass tees. Or if anyone knows of another way, I'd love to hear about it. Sorry for the hijack, just figured I'd add some (potentially useful) information. Best of luck with your fix-up.
