Kink in flexible copper tubing underground

[mdavis130]

Is it possible to repair a kink in flexible cooper? I have a kink in a section that is underground in a masterbath. The concrete in the old shower was jackhammered out in order to pour a new pan and floor. The kink is just below the ground where it bends to feed the faucets in the kitchen. This happened after I cleaned up some old plumbing. I think what happened is when I was putting a coupling on the 1/2 copper stub coming out of the ground into the stud wall I had to tap the coupling on and in doing so, the copper pipe kinked at the bend just below the floor.

If it is not repairable, are there any additional requirements for soldering a sleeve underground? I have always heard that it is not recommended to have any joints underground (for obvious reasons).

Thanks for any help

Underground soldering must be done with silver bearing solder...or a mechanical repair with a pack joint coupling...there is a brand of solder that is called "silver solder" that contains no silver...do not use it...it can also be braised...but the other 2 ways are generally easier....

Someday that kink may cause a problem by cracking the copper tubing, so you should fix it. Brazed joints can be used underground, but they can cause different problems. Using a flared joint is the best way.
