How to cut All Thread?

[pprince]

Greetings,

Plumbing novice here, but pretty good handyman.

We are in the process of remodeling a half bath. We just fired the plumbing contractor (referal of a friend) at about the half way point in the job because of problems. We are converting from a standard sink and top mounted faucet on a vanity to a vessel sink and wall mounted faucet with two handles.

The contractor extended the old plumbing up to the proper height and set the mixer valve into the wall. It is from California Faucets. He drywalled everything up and painted. Then problems. Now I am finishing the project.

The brass mixing valve set into the wall has two brass handle stems coming out and I need to cut off the 9/16" All Thread to the "depth" of the "bell" housing then cut off the stem broach.

How do I cut off the All Thread without cuting the stem broach off at the same time? (i.e. hacksaw) I'm guessing a pipe cutter will follow the threads down the thread?

Second question if I may. The center outlet has a brass nipple that is loosely threaded in place. I know that I will have to thread this in tightly before screwing on the faucet. Should I use teflon tape or pipe thread compound between the brass nipple and the outlet? And between the nipple and the new faucet?

Thanks in advance for your help.

If I understand your question, you just need to cut a piece off the all thread. To do this, use a hacksaw, but before you cut, run a nut down past the section to be cut. After you cut, take a flat file and round the cut end over a bit. Now unscrew the nut. This will open any flattened threads so you can screw the all thread. You might want to work the nut on and off several times. If you happen to have a tap and die set, then just use a die to clean the threads. I have cut many bolts to length using this method before I got a die set. Sometimes a little more file work can help clean the end up if necessary.
