    Well, you could solder with a coupling. If it is not concealed you could reconnect with a compression coupling or a Sharkbite coupling.

    Hi all...

    Just wanted to provide a visual for Joefam...

    Like Harold said, if concealed plumbing (wall will cover) then you are best to solder the piping using some copper couplings. If the pipes are exposed then you can use 5/8" O.D. compression couplings or use 1/2" copper sharkbite or gatorbite fittings.

    The sharkbite or gatorbite fittings (see images below) are easiest in that they are simple PUSH FIT type fittings. Here, you must have a clean cut on the copper pipe and then you simply push the coupling (or any type fitting) onto the pipe to the proper depth.

    You will probably need to purchase a small piece of 1/2" copper pipe (TYPE L for drinking water) and 1/2" sharkbite coupling(s). Also, not a bad idea to purchase a tubing cutter (see last image) to make the cuts nice and smooth.

    Let us know if you want to discuss more here...

    You guys forgot the most important part. There is the REPAIR COUPLING and a COUPLING. Only the repair coupling will work because the tube won't stop in the middle due to a dimple or score.

    You can cut the tube in half. Prepare the ends and slip a repair coupling on one side. Put the pipe together and center the repair coupling over the seam. Solder.

    Good point KISS. If Joe only has a single cut that needs to be repaired he can just finish the cut in the pipe, clean all this up and install a repair coupling and solder this all up as you mentioned.

    If he has to span a small distance due to damage to the pipe he can use a regular coupling and then span the distance with copper tubing and connect all up using that repair coupling you mentioned. Certainly makes things easier if there is no room to move the pipes!

    Otherwise, if there is room to move the pipes... sharkbite or gatorbite fitting is still best solution if Joe doesn't have all the soldering tools!

    Thanks..

    At the price of those sharkebit or compression fittings or how long they hold up compared to sweated fittings! Learn how to sweat and buy the torch!
