I have a 3/4" copper water pipe that has a bad section. I cut out the bad section...?

Question

I cut out the bad section, Only about 3". Is there a way to replace the 3" bad copper piece with PVC pipe? And if I can, How do I connect the 2 open copper ends to the new pvc replacement pipe. So the original pipe looked like this _______. I took out 3" in the middle so now it looks like this _____ _____. So asking if I can put a pvc pipe in that gap and connect it water tight with the copper? Thanks for your help. I am sick of doing this!!! Thanks

Answer 1

Go to Ace hardware, and ask for a slip on compression fitting, named a Shark bite fitting. It will slip over the copper, and you can install a replacement piece of copper pipe, without soldering. You will need two of these fittings, and a piece of copper pipe. Slip it all together, and you are good to go. It should take less than a minute to do it, and it is all copper. Good luck!

Answer 2

The p;previous answer is good. You can jerry rig it with PVC compression fitting. But I would stick with copper.
Go to Lowe's or your local hardware store and explain it to the clerk. You can get a copper union and sweat the union to each end of the pieces. It will be just as sound, better than PVC and you won't have to worry bout it.
If you don't know how to sweat copper, again ask the store clerk or better yet get one of those simple how to books with detailed pictures and steps.
If you do it, BE CARE FULL, make sure that the pipe is far enough away from the wall. And/or place a piece of flame proof material between the wall and pipe. It is possible to heat up, state a fire that will build up after you finished and not know it.
Then you house would be gone and all you would have is the copper pipe.

Answer 3

You can connect it,by applying some glue/sealant inside the PVC pipe and wait til it dry before you used it.but the problem is this,if you are using it(the pipeline)for a warm or hot water,then it will not last long.Cause PVC are mostly made up of plastic even if it not melts it will get soft for the long period of time using the hot water and when you stop using it(hot water)the temperature will comes back to normal or maybe lesser,because of constant change in temperature the PVC might get brittle and will cause again some problem.It's better to use the same copper pipe to use as your connector in between this gap by gas welding(acetylene/oxygen)and hire some proffesional to do it,in case you can't.

Answer 4

I'm guessing both ends are ridgid and dont move, so you need a repair fitting longer than the gap of 3" so you can slip it over both sides, right?

A PVC compression fitting would work, but the same fitting is available in brass, and is a better way to join them.

Here is a picture and place to buy it for $5: http://www.doityourself.com/invt/6104855

Soldering copper tube requires special tools and some experience and you can get one of these at any good hardware store.

Answer 5

Wow. I have never seen graphics in a question here. Nice job! To answer your question ,yes. You can do this with pvc pipe and two >copper to pvc connectors<. The mega-box home improvement place has a bin full of copper to pvc connectors and, most of them come in a plastic bag with instructions. You'll be done in 20 minutes.

Answer 6

Other considerations should be made.
Make sure the copper pipe you cut is not part of a critical electrical ground to something in the house. If there are any grounding cables on it you'll need to replace it with copper. If not, it's ok to go with the PVC gasket clamp on type joint.
Stick with all copper if you can.
Ask your local hardware vendor for what you'll need. Including a slice of bread. They should be able to tell you why you'll need that too.

Answer 7

If you cannot solder , I would do it the way Poppyman said, 2 compression fittings and a piece of copper pipe. The only tools you need is a couple of crescent wrenches and a pipe cutter 5 bucks for the cutter , piece of cake repair.

Answer 8

It's not recommended but it can be done. It still will require soldering, so there is really no advantage. Essentailly, you can solder a female adapter on the copper and screw a PVC male adapter into it. But why bother? If you dont want to solder, I recommend you use copper pipe, 2 couplings, and a glue that is designed to replace solder, I forget the names of these products, but a good plumbing supplier will know.

Answer 9

Hello,
you could use pvc but you will end up with a lot of joints. Why not use copper , soldering is easy and a little home owner torch is fairly cheap. What is the cause of the failure?

Answer 10

i would just get 2 copper couplings and a little section of copper pipe and sweat them together it is quick and simple fix
