That reminds of a camp fire trick that we used to do years ago!
We drilled many, many holes all around a piece of 1 1/2" copper water pipe!
When this is placed in a camp fire, it gives off emerald green flames!
Something to amuse the kids! (grin)

How To Solder Copper Pipes


I have tried soldering and found Rescue tape or the InstaClamp to work quick to repair leaks on solder joints on my copper pipes.
www.rescuetape.com or www.instaclamp.com

Sure saved me a lot of time and money and from paying a plumber extra after I screwed up the job. Oh yeah my wife likes the fact that she didn't have to go the whole weekend without hot water.

Enjoy!

How To Solder Copper Pipes


I'm not an expert in soldering, but I did recently read some good articles on the subject. there's one on {link removed - please stop posting the same links to try to drive people to your site} basic techniques as well as an article on{link removed - please stop posting the same links to try to drive people to your site}. I'm just starting to learn my way around this stuff so I'm no help myself, but maybe these will help point you in the right direction.

How To Solder Copper Pipes


Nice thread. I had a heck of a time (gave up) sweating some copper pipe a while ago. Prep was good, got new solder, flux, etc. It just wouldn't work for me. Years ago, the lead solder was easy as pie. I got a MAPP torch, and told myself I'd practice, but still haven't.

Is MAPP the key for the 'new' solder?

No, not at all. Propane is more commonly used. Mapp gas is hotter...Once you get the hang of it mapp gas is great but it certainly won't make or break you.

If you failed at soldering I'd look toward two things first off:
1) water or steam in the lines. Even if there is water downstream or upstream it will migrate to the heated joint and prevent you from succeeding. The bread dough trick works wonders to deal with this.
2) unclean fittings and pipes. Gotta use a wire brush on both.

How To Solder Copper Pipes


Any advise on the use of a heat gun instead of a torch to heat the solder?

The advice would be not to use it, because it won't work. Torchs are pretty cheap and have a low learning curve. If you're soldering 1/2" and 3/4", you can use a small propane or mapp gas unit. With larger pipe sizes it's problematic.

How To Solder Copper Pipes


This thread is old but I got notified so I thought I'd chime in once more.
I found the secret! I got a blister pack by Oatey that came with self-tinning flux and solder that said it was just as easy to use as the old stuff, and it was! I think the key was the self-tinning flux.

How To Solder Copper Pipes


I've always used a damp rag to wipe the solder right after finishing
I noticed on one pipe that there is green "residue" - must be left over flux

I've also pre-tinned (soldered) pipes before putting the fitting on
Once the pipe slips in I add a touch more solder & it's good

Why not? The heat guns heat up to 1000 degrees, and from what I understand, the solder melts at 240 degrees. I saw a guy who said he does it without problems- but I really haven't seen too much info about it. I just bought a milwaukee heat gun (570/1000 degrees) hoping I could also use if for this purpose (in addition to others)- it even comes with an attachment for soldering pipe (hook nozzle).
Here it is-

Just wondering if anyone had tried this- otherwise will go with the torch.

Thanks.

My heat gun has no such option. If yours did, you might have included that info in the post.
Try it on a scrap piece before the actual work.

That was a useful tutorial. I've never done it before, but been thinking of trying, and water pipes scare me more then anything else as far as DIY so I want to make sure I do it the right way!
