Odd size steel pipe nipples
I'm putting in a tub faucet and need a 3 1/4" nipple in order to have <1/8" gap to caulk. Using the standard 3 1/2" that I can get at home depot, I end up with a 3/8 gap which seems a bit much, and 3" is too short.
The Home depot guy said to mate up smalller nipples with a coupling; is that the typical solution for pro's? I'm nervous enough about having two hidden joints in the wall that could leak, much less four. It also seems like it'll also get squirrely trying to get the faucet to end up in the down facing position when they're all tightened up.
How do you folks do it, or am I making too much of this?
