PEX damage (repair/replace?)

[weagle]

I opened a wall because of a drain problem and accidentally grazed some PEX that I did not know existed (the rest of my house is copper). It's been almost 24 hours and the line has remained under pressure and has not leaked, yet. Should I repair or replace this small section while the wall is open or just monitor for more time to be sure it will not fail? Thanks

I am not a plumber or a pro. I did the same thing a few years back on a heating line. I ended up cutting out a section where I had hit it with my drywall saw. I then bisected the piece at the point I hit. The damage was a lot deeper than it looked.

How deep is it... pex is less then 1/8" thick. If we are talking a hairline cut... then leave it. If more fix

That cut is also at a point on the pipe where it is bent on a radius which will add additional stress on that area of the pipe.
There will never be an easier time to address that than you have right now. If it does start to leak in the future what will you have to do to access it?

If you put a coupling there, it will increase the diameter. So avoid having that press between the drywall and the steel pipe. That would be especially important if you used a SharkBite push-to-connect coupling, which is bigger than a crimp or clamp coupling.

That might mean that you would use two couplings, or, if there is a lot of slack, it could be that you would support the coupling off to the side.

What does the fingernail depth gauge tell you?

I have yet to turn the water off and really stress the cut.

Thanks for all the replies!
