Question about Plumbing
I will be doing a little plumbing job that I am worried about. The plumbing was put in aroung 1920 and it is 1/2'' galvanized pipe. Going to try to remove from the end of a line a fitting and connect in with PEX. My fear is when I remove the fitting the threads will peal off and I will have to go to the next joint and have the same thing happen again. If the threads do peal off is there a connection that I can make in the middle of a nipple that does not require the use of threads? I was wondering if a compression fitting will work??
They do make a compression coupling for galvanized pipe, but I don't trust them very much. When you unscrew the joint with a pipe wrench just make sure to back it up with another, so you don't start to unscrew the next joint back.

Sharkbite fittings are not designed for galvanized pipe. They are designed for copper, pex and cpvc gauge pipe. Try to only cut the galvanized pipe with a hacksaw or a pipe cutter ( with wheels). A power tool such as a reciprocating saw will vibrate the rest of the plumbing and cause future leaks. You can go to the next fitting and install a male thread by compression type transition fitting. It is very important to counter hold any galvanized fitting to prevent any movement that may leak.

I'm a big fan of the SharkBite push fittings-- now if you are doing work behind a wall most tradesmen will not recommend using one of these because they have not been tested over extended periods of time-- however from my experience they work great and could not be easier to use!
