Replacing angle stop, old compression fitting crushed copper pipe

[Djarchow]

I am replacing a 20-year-old angle stop for a toilet. When the plumbers put it on, they tightened it too much and the compression fitting crushed the pipe some. It isn't bad but you can see and feel it. Plus, I managed to scratch the pipe taking of the old olive as I had to cut and break it. I filed the scratch down, but I can still feel it. The new stop doesn't fit as deep on the pipe as the old one, so the new olive straddles the front of the crushed area. I tried putting it on there and it was leaking quite a bit, though I didn't go crazy trying to tighten it. I assume it was because of the olive straddling the spot where the old olive was and maybe the scratch I put in the copper. I can cut some off the pipe so the olive would be behind the crushed area but not by much, and there wouldn't be enough pipe left to cut it off again if needed.

And yes, I have a new escutcheon, just hadn't put it on for the picture.

Thanks for any suggestions!

Generally I try to leave the old ferrule and replace the stop. When showing up to do this I get two different brands of stops. Like you said some fit deeper than others so I try to bring a deep fitting stop and a shallow fitting stop. It seems you've gone too far to do it the easy way.

You can either ream the copper back to it's original size with a tool or cut some off and redo it.

John,

Thanks for the reply. I appreciate it. I thought about trying to use the same brand stop but being 20+ years old I couldn't find one to match.

If I cut it back, how far back from the indentations from the old olive should the new olive go.? For example, if I cut it off so the new olive goes about where it is in the picture, is that enough?

Thanks again!

The stop will tell you how much pipe you need. Take a piece of pipe and insert it into the stop with the ferrule and nut. Mark the pipe. Measure to your mark. That's how much good pipe you need.

Yes. Cut the pipe, and clean the burrs.

A little lube on the olive and threads will help you tighten, especially if your wrenches are short or access is awkward.
