I have a hole in a copper pipe in my kitchen sink. I need to know how to replace that pipe with a new pipe?

Question

copper pipe is conected to a main pipe. do I need to sweat the pipe to get it to come apart to put new pipe on

Answer 1

You can cut out the section that is broken with a copper tubing cutter. It looks like a C-clamp but has a small cutting wheel on one end. They even come in small models to fit into tight areas. Just turn the water off and open the faucets to let them drain as much as possible. Put the cutter around the pipe and tighten it up a little. Spin it around the pipe, give it another turn to tighten it, and spin it around again. The pipe will eventually pop apart and leave you a nice clean cut to attach the repair to. The pipe and fittings will need to be dried, then sanded to remove dirt, etc., fluxed, assembled, then heated with a torch and soldered. Two connecters and a very small length of of same sized pipe is all the parts you'd need. If there is a wall close to the area that needs to be soldered, find a piece of metal to stick between the wall and the joints. It'll protect the wall from catching fire.

Here's what you really need to do to fix the pipe. Turn off your water supply to the house and open the faucet to drain off the water pressure. Using a pipe cutter or hack saw, you'll have to cut your existing pipe near where the leak is. Note that many have advised using a torch to melt the solder in a close joint, but with the water in the line (because you won't be able to get the water out of all the pipe), it will take forever to heat the pipe up enough to melt the solder and the water that comes out if and when you do get it melted will be dangerously hot). Go to the hardware store and get a new coupling and see if you have enough room (straight pipe) to install this where your leak is. If you do, measure how much pipe you need to remove on the piece with the leak and cut it off. If you can't fit the coupling, you may need to remove the bad section of pipe and install a new piece of pipe. If you have to do this, you should be able to apply heat to a joint and pull out the old piece of pipe. then, use the pieces you removed to cut your new piece.
Prepare your existing pipe and coupling, or new pipe and existing joints for sweating, and apply a good coat of flux.

Answer 3

You will need to "Sweet" a new piece of copper pipe. First shut off water, drain the water. Next using a blow torch heat up the joints of the old piece. Next using sand paper rough up the ends of the new pipe then fit into place. Apply some flux to the joint then heat up with torch. When hot apply the solder to the joint allowing it to flow into the joint seam. When cooled down turn the water back on and check for leaks. Good luck.

Answer 4

turn water off to that section. cut pipe where the hole is (pipecutter) if its 1/2" copper get a 5/8" compression coupling. using 2 wrenchs tighten both sides. turn water back on check for leaks. your done.

Answer 5

There is a compression fitting made just for that purpose. Cut out the bad section and replace using a new piece and the compression couplings. No soldering needed Check with a plumbing suppy house, they speak the lingo.

Answer 6

Use a double ferrule oil and gas compression fitting..Cut off the desired length and use the compression fitting to join the two pipes

Answer 7

are you asking about a small water pipe or the drainage line ? If its drainang side cut it out and replace with pvc .

Answer 8

you gotta sweat the pipe then pull it back and forth till it releases all the fluids then you must insert it into main pipe ..... good luck mate .... maybe some plumbers tape or clingfilm would be of use

Answer 9

switch off the water mains, cut out the damaged section and fit a speed fit, push on connector. jobs a good un. turn on the water mains, finished.

Answer 10

Most of your fixture connectors that are visible are threaded flexible connectors and can be replaced as a whole.
