Nicked PEX

in THE MAIN WALL
One of our contractors was doing a concrete repair and nicked the snow melt pex embedded in the sidewalk.  We will have to clear back enough concrete to get to the piping.  Once there what is the best way to repair this?

    I just did this yesterday...

    I used the Wirsbo ProPex expander with brass barbed coupler.



    Make sure you have enough room to move the tubing around as well as get the tool into the hole.



    In lieu of the ProPex expander, you could use a Watts crimp ring assembly. But you will still face the same issues of tubing free play, as well as being able to get the tool into the hole.



    I now know how my dentist feels.. I promised the custoemr I would keep the hole to less than 7" in diameter, so he can core drill a 8" plug for replacement (stained concrete).



    Good luck

    It's not so much a case of "You got what you paid for", as it is a matter of "You DIDN'T get what you DIDN'T pay for, and you're NOT going to get what you thought you were in the way of comfort". Borrowed from Heatboy.

    Brass protection

    Mark, Did you do anything to protect the brass from concrete contact after patching?

    Not much brass exposed...

    but 2 wraps of mill tape should cover it.
