Bathtub spigot replacement
HI I just join your group and hope you can help me. My husband replaced the spigot on our bathtub, but the first time some one used the shower the water back up in the wall and flooded the master bathroom as well as the basement. There are no threads on the pipe it has the little hex screw is there something he did wrong or did we get a bad replacement spigot?
Thank you

The tub spigot has a small O ring inside and usually fits over a 1/2 inch copper pipe. Overtightening the hex key can deform the copper, a relatively soft metal, and result in a leak. Another thought, the O ring may be bad even though this is a new spigot. The copper pipe should be checked for damage and if it shows no damage you can lightly polish it with steel wool to remove grime or corrosion if need be. If the spigot still leaks, it should be replaced.
A few days ago I received a brand new spigot from Kohler to replace a tarnished one. The next day I found that it was leaking over the tiles and into the overflow which I had not sealed adequately. I just finished repairing the drywall in my kitchen ceiling directly below the tub. When I put on the old spigot there was no leak.
One final thought, the end of the copper pipe should be smooth and rounded slightly on the outer edge or it can damage the O ring during installation of the spigot. Emery cloth can be used to remove burrs on the exterior of the pipe (just the tip).

I would also like to suggest sealing around the hole that the copper pipe for the spigot passes through so water can't get into the wall. You can use silicone caulk, plumber's putty or even spray foam if the hole is really big. After the leak issue has been resolved, a bead of caulk around the rear of spigot where it meets the tile would not be a bad idea either.
