for my toilet I have copper pipe coming out of the wall and it has a large nut looking thing, then the valve is threaded onto the nut.. can't tell for sure as there is teflon tape on all the connections including the 3/8" comp hose!

I thought usually 1/2" pipe with compression fitting? Or does a sweat on pipe thread nut is common also?

I will have a picture soon.

I really do not like this type of fitting where the fitting is not captured. A shark bite or compression fitting is OK when it is inline and both sides are solidly clamped, but I really don't like then on the end of a stub out like the owner describes.

what do you mean by captured?

I want to replace the valve because I think it is slowing the flow to fill the toilet.. with ball valve, just wanted to know the new valve to get.

Thanks

We can play the guessing game all night long or just post a picture and know know for sure.
How do you know it's the valve? Just shut the valve off, disconnet the line from the toilet and try running the water into a bucket to see if it's the valve.
Far more likly it the flush valve that's pluged up.

Your description matches that of a compression shut off valve---

I guess the teflon tape throw me off, why do people put teflon tape on any kind of threads?

Its a right angle supply valve. There should not be Teflon tape on either nut, because the seal is not made at the threads. This type of valve should not be slowing down your flow. Adjust the float assembly so the lever drops further, and allows better flow.

If the valve is full of junk it will slow it down :)

Your dealing with a lot of extra parts!:laughing:
Just cut that mess off of there and install a 5/8x3/8 comp angle stop,preferably a 1/4 turn valve :)

Anyone else have idea what are those adapters?

Is it a 3/4" MIP to 1/2 MIP for the 1/2" angle valve, it looks like a nipple type (male both ends) than the bushing type.

like this one?

No, what you have is a compression union. 5/8" OD tubing x 1/2" MIP and that is in turn threaded into an angle stop valve.

The easiest solution is as plummen suggested, cut the pipe off right behind the nut and replace with a 5/8x3/8 compression angle stop. You have plenty of pipe sticking out to do so.

You just simply push the new valve onto the end of the pipe and tighten the compression nut while holding the body of the valve, it replaces all of that mess of parts. Your braided stainless line will then connect right onto the 3/8 port on the valve. Skip the teflon tape, not necessary at all with compression fittings.

You can buy this valve at most any local hardware store, here is an example of what you need. You just discard the small nut and ferrule and attach your braided stainless line. Take the old parts with you and if the store is competent at all they will fix you up in short order.

I should be able to buy a 5/8" OD valve and try to reuse the ferrule and nut on there first right?

If that does not hold then I will cut the pipe?
