I want to replace this angle stop with one of those quarter turn stops. Can I use the sharkbite
on this pipe? Thanks for any help.

You can do whatever you want, but why would you want to use a sharkbite when you have a compression stop there already?

Thanks for the reply. I was trying to "update" the look. There used to be a vanity in that spot and I'm replacing it with
a pedestal. I guess my question would be, can I cut the pipe and just put in a sharkbite?

Sharkbites are not the best mousetrap. Yes, they work, and yes, they serve a purpose. Compression stops are the plumbers' first choice followed by sweat fittings. Compression is the easiest and is a safe and sure connection. Sweat joints work great, are very safe and sure, but do require care in installing when working in tight space and/or close to a wall. Since you already have a compression joint, why change?

No you cannot use a sharkbite on that pipe. Thats a 3/8" chromed plated brass nipple. It has male threads on each end. You need a 3/8" fip x 3/8" o.d compression angle stop. It will screw on the existing pipe or if the existing pipe is too long you can buy shorter nipples and replace the one thats there now. It should unscrew out of the wall. Dont forget to turn the water off and drain down the pipes.

Those brass nipples have a tendency to break at the threads so it wouldn't be a bad idea to replace them.

The stop should unscrew from the chromed brass nipple. Or, if you're not careful, it will unscrew in the wall.

Yes, but the other end of that pipe is also (very likely) screwed into a fitting in the wall so you'll need to hold it from turning while unscrewing the valve.

Pull the eschution out from the wall and put a pair of pliers there where the nicks and scratches you might put on it won't show.

If you're installing a pedestal lav, you may want to get a shorter nipple for the drain.

Or something like this

Thats a good tip. No way that would connect like it is. if he could get that nipple out he may could use a 1.5 pvc male trap adpater and a 1.5" female trap adapter and solvent weld them together makign a short nipple that tubular would connect to.

Isn't that making a "close nipple" the hard way. Besides, the "thread" on a trap adapter is not meant to screw into a fitting. He would have to put an "O" ring over the thread to squeeze against the cast iron fitting to seal it. He can just buy a 1 1/2"xclose galvanized nipple, but what he really needs is a brass 1 1/2" x 1 1/4" brass trap adapter

No that would be making it the easy way and its commonly found....especially in my service van. How long does it take to solvent weld a joint? How much does plastic cost compared to metal? Sch. 40 pvc installed correctly will outlast the rest of his piping.

You could use 1.5 and solvent weld it into a 1.25 trap adapter. No pipe needed. The fittings solvent weld one into another.

The threads will work fine. A 1.5 slip joint nut will screw onto a copper male adapter. The same slip joint nut will screw onto the plastic trap adapter. The same copper adapter would screw into his tee. Conclusion......the threads are the same and will work perfectly.

It works without issues.

you've read my mind terry. that's my next issue. that drain really looks ugly. i really dont want
to mess with it (i.e. remove it). i'm thinking to dress it up, i'll do escutcheon, a sched 40 dwv pvc,
1.5 p-trap adapter in this order. what do you think people?
