HOw to replace small sectin of copper pipe

THanks Here's a couple of sites with good tips: http://www.easy2diy.com/cm/easy/diy_...ge_id=35694426 http://www.copperkeytools.com/historyplumbing.asp When cutting out a small section (2") you may not be able to move the pipe enough to use ordinary couplings. Pick up a couple of "repair" or "slip" couplings. They solder in the same way but have no internal stops and can be slid completely over the pipe. If this is a tight space, protect any nearby wood or paper products from heat and flame. Put a metal heat shield behind the work and wet down combustible surfaces. Consider adding electrically-heated pipe tape in this area. Jim |

THanks its hard to fix just a hole in the plubming when working with copper/soldering.. you might have to go a little further and replace the complete section or about 2 feet of it.. remmber that if you have water in there its gonna be hard to work up a good heat to do the soldering and the water turns into steam and blows out the solder(so you dont get a good seal) thats what happend to me on a nail hole in copper.... |

Get all the water out the the pipe. Buff the pipe ends with a little emory cloth to get the oxidation off. Use a "repair coupling" instead of normal a normal coupling for one end of the patch so you can assemble everything. Brush the insides of the couplings with a wire "fitting brush" will make it easier to solder. Use plenty of flux when you solder it; when you get the pipe hot enough the joint should suck up the melted solder. While the joint is still kind of hot, wipe with a damp cloth to remove the excess flux. I use a piece of steel cut out from a can to shield the nearby wood to keep it from burning.

I had a similar problem. We opened faucets on either side of the line we were working on so the water/steam would have a means of escape, but it wasn't as helpful as we would have liked. There's also a cloth product that helps you avoid accidental fires, but it never hurts to keep a couple of buckets of water &/or extinguishers nearby. |

Getting the water out will be a problem. Sweating wet pipe is difficult if you know what you are doing. Trying it on your first time will be a real challenge. There is an epoxy made for copper pipe. I have only used it once where I had no room to get a torch in, but it was pretty easy and hasn't leaked after a year. Just an idea. Of course, the outside of the pipe still has to be dry, but the inside doesn't matter. |

HOw to replace small sectin of copper pipe
"Joseph Logan" I still haven't started soldering, but I have read in more than one space that putting bread without the crust down in the pipe will eliminate the chance of steam. Haven't used it much but bread seems to stop water running down into the work site at which point it turns to steam and you can't solder! If you can't open a faucet, empty toilet or something 'lower down' in the system you might be able to push a small plastic pipe down the pipe a certain distance say 24 inches and either blow or suck out excess water? Idea. |

HOw to replace small sectin of copper pipe
To hell with it all. I used to use a torch, now I use Copper-Bond. Joseph Logan wrote in message m... (Heathcliff Bambino) wrote in message . com... (Joseph Logan) wrote in message . com... Thanks for everyones help. I bought all of the materials and started the prep work. I have removed a 2 inch section of the damaged pipe and cleaned the inside of both ends as well as the new piece I cut with a wire brush for the inside and emory paper for the outside to remove oxidation. I also stuck a small baster down in the pipe and tried to remove all the water that I could. I know that there is at least 6 inches of "dryness" below the part of the pipe I am replacing. Is this sufficient or is their a chance that steam will build up down there and condence on the hot pipe near the point where I will be soldering? Well how did it go? I was going to suggest more efforts at draining the pipe -- most houses have some way to shut off the whole water system and drain it. Or you could try to finagle it by opening a lower faucet somewhere, if you have one. Or get a 3 foot length of plastic tubing and attach it your baster. I still haven't started soldering, but I have read in more than one space that putting bread without the crust down in the pipe will eliminate the chance of steam. |

I still haven't started soldering, but I have read in more than one space that putting bread without the crust down in the pipe will eliminate the chance of steam. As much as steam can be a problem, lots of standing water in a vertical copper pipe will act as a heat sink, and keep the joint from getting hot enough for the solder to stick. You'll know if you are going to have this problem when you solder your pipe. You may have to remove more of the standing water. The bread trick is good for drying that area around the joint you are soldering, and for holding back a little water seepage if you have a bad shutoff valve that lets a trickle of water pass thru.

The area to be soldered will heat much quicker than with propane. Standing water, unless it is very near the joint, shouldn't be a problem as the joint will heat faster than the water's ability to 'heat sink' it away. |

You read WHAT???? Hahahahahahahahahahahaha........ Wow, I got to see that book....... Is that the redneck book of fixing stuff with ducttape, or what? Actually he's half right, dorkus, and HVAC guys have been doing it for ages. Shoving a big hunk of bread (no crust) into the pipe won't "eliminate the chance of steam," but it will eliminate all that residual dripping all over your nice carpet or floor once the line has been cut and drained once the zone has been shut down. Bread is used because once the repair is done and the zone is opened back up, the bread "plug" will disintegrate very quickly once the hot water nails it. Of course, you could let the whole line drain bone-dry into a bucket for a day or two, but most repair guys don't have that kind of time. AJS |
