Default Leaky Curved Copper Pipe

I was wondering if anybody has any ideas on how to fix a leak in a curved copper pipe? I considered cutting the leak out and using a Sharkbite slip coupler but I cannot slide the slip coupler over it because the pipe is curved.

Thanks in advance.

If it's copper, why can't you cut the pipe, slide a union on and solder the joint?

I normally would. The problem is that it is the pipe is under a concrete slab under the house. I can only cut what I can see and I can only see the bend.

Thanks for the suggestion though.

Have you a reason for this leak. If it is a bad peice of pipe or corrosion of some kind, you could expect it to leak again. How hard would it be to remove or by-pass this peice?

I think it is a pinhole leak in the copper pipe. The copper pipe is under a wall that I can only get to by digging a small trench under the foundation through a 8x12 inch hole in the foundation in the laundry room. It is very tight and I am limited on how far I can dig.

Unfortunately, I already know it will happen again as this was a very poor design. Basically, instead of using an elbow, the builder bent the pipe and poured the slab above it.

I really do not want to jack hammer the slab more than I have to as I live in earthquake country and do not want to weaken the slab more than I have to.

I am hoping that someone here knows some trick that will union a curved pipe with a straight pipe together without near future problems.

Thanks in advance.

Sharkbite on a curve is NOT good ... I have seen water heaters setup that way and the leak was terrible.

I would prefer to go with the flow! If you have a bent pipe, cut out the problem area and rebend a new piece which is cusome crafted to match. I use a bending spring (readily available and inexpensive) which is inserted in a longer pipe. Once you get the right bend, remove the spring, cut the section you need, resolder it into your problem area. Tricky in your case but it might work.

Here is a video to show you how to bend the copper to match your problem area.

Thank you Nealtw for the suggestion for the tool. I looked at it and it is just too expensive for me to buy it for one time use.

Thank you CallMeVilla for the suggestion. Do you by chance know where I can find a coupler that will union two pipes with a bend? Preferably without soldering? The work space is very small and I really don't want to accidentally burn myself.

Thanks in advance.

You keep backing yourself into the Sharkbite corner ... That is the only non-solder option.

Honestly, your concern about destabilizing your house if you remove more foundation seems over-stated. Work gets done on houses all the time and the cement is replaced ... you could add rebar if it makes you feel more happy.

For a proper fix, you need access ...
