I posted this earlier but perhaps in the wrong section . My apologies . I’ve been working under my house replacing most of the galvanized half-inch with PEX. I have one long continuous pipe that runs to the far side of crawlspace with cery difficult access. I found the spot to tie in but While trying to get the T loose I started to unscrew the long stretch of galvanized pipe. I only turned it about a quarter turn. Then retightened it. I’m wondering if Breaking the original bond will cause this point to start leaking. It is out of my sight and very difficult to access. However I don’t want a leak either. Any opinions on if a quarter turn on an old connection will start leaking? Thanks in advance.
