So I'm in the home stretch on my bath remodel. I've got everything in except the vanity top, sinks and fixtures. The toilet is in and working, the tub/shower is in and working. I've got an annoying leak that I can't seem to get to stop. It's on the tub shut off valve (hot side). The issue is that I would like the handle to point toward the wall to the left, but it's just a bit less than I need to make it tight...The inlet side of the valve is 1/2" NPT and that's where it leaks. The outlet side is Compression, and hasn't been a problem. I should note that I would have been fine had I ordered the 1/2" comp to 1/2" comp valve...and now I'm paying the price... Are there any "tricks" I can use to make it tighten sooner???
