Excellent. I came to your video specifically wanting to understand how best to remove the old solder (and whether I need to remove ALL of it) after taking a leaking soldered joint apart, before I remake it with the old components. Your video was the first one I found that gave a complete and reassuring answer. Many videos deal with taking old soldered joints apart, but skate over the steps needed to reuse the old components. Thank you for taking the time to film and post this and for the choice of keywords in your Title, which acted like a magnet!
Agree, great videos like this get hidden under mountains of low quality mass-produced copycat videos. You got to dig for quality! I've done lots of copper pipe soldering but I run into weird issues ever so often. I use water spray bottle & wet rags on valves but will need to use some metal outside against the stucco which has a fiber optic cable for the internet running next to the pipes I need to solder for an outdoor shower. could figure out how to mount the Flame cloth to the stucco :-) Also, I like using the camping style cylinder but wasn't sure if that was an accepted practice.
@cookerdonkin1333 good point - most people would say just throw the old pipes out but if you are replacing a sweat valve or need to rotate a pipe to move it out of the way of a repair these tips are really important. Also, they offer a proven method vs guessing and hoping it was done right.
I used to think the old solder had to be removed completely. That makes it difficult and time consuming. But I recently learned that's not the case. This is much better!
This is a live saver. I had to watch to the end because I wasn't heating up long enough and had vise grips attached during the heat attempt. Used my kitchen butane torch to remove a copper coupler, that corroded, remove 2 inch of pex, then installed a sharkbite slip coupling. Coupler was first Gen on clearance for 4.62. My plumber told me it would be $450 to have done today (Sunday).
I was a Coppersmith in the shipyards. I used fine steel wool to clean off the old solder after sweating off the old copper joints. It saves a lot of time because you don't have to use emery cloth to cleanup of dirty contaminated solder. Also, if you don't have steel wool you can get the pipe hot and use a wet rag and wipe the hot solder off the copper pipe. It's even easier than using steel wool and less clean up also. Some guys don't have steel wool and it saves a trip to the store this way. Just be careful and use leather gloves while doing this.
Nice , nice vocal presentation coupled with visual examples . And you got right to the point without explaining all about how important it is to have non leaky pipes, how I can save money doing it myself , blah , blah blah .
Excellent video. The only issue is when you need to do this desolder in a enclosed area.. For example: inside of a wall, where is not possible to twist the pipe.
Here's a tip - you could cut the pipe, and splice in a new section of pipe and use "no stop" copper coupling - stop is removed so the coupling can be slid down the pipe then insert and slide in place - great for when there is zero room to move a pipe out of the way.
You can sometimes see the solder change from a satin to shinny finish. Typically I just go by experience as the solder can't always be seen if it was a clean joint. Other times you'll see the copper pipe change it's color tone. But neither is like steel where it becomes red when it's excessively hot.
Can I clean up an old joint and heat it up without removing the joint and finish it with additional solder? The lead is strongly bonded and brittle. More regular white flux is no use. I need to strengthen the solder without removing a jucntion
To reused the fitting, can you heat the fitting up to melt the the solder and slip it back on the pipe and then keep heating the pipe and the fitting to the right temperature and add more solder to it? Oh per hap do the same thing to the pipe without the cleaning the solder.
I wouldn't recommend that, because in heating the fitting you likely will burn off all the flux that you did put on there. Honestly, refurbishing old fittings is rarely worth it, just buy new ones as they are usually pretty cheap.
@@LuminaryGames Fittings _used to be_ cheap, but now that even fast food is up something like 25%-75% it's looking more and more worth it to take two minutes cleaning an old fitting. $2 saved for 2 minutes works out to $60/hr
@@user-ut9ln4vd5m Honestly if it only takes you 2 minutes to get it to a state where its clean and ready to go, then yeah the numbers look good. For me on a good day I am looking closer to 10-15 minutes.
LOL no doubt, he probably doesn't do it. This was for a video, but he probably just buys replacements. The amount of time and effort to clean the fitting would be hard to defend.
The hottest part of a flame is the end of the flame where the fuel has given up all its energy. The light blue flame is fuel to be consumed and moving very fast.
With the price of copper what it is, reuse is the only way to go. I was hoping for some magic trick... There is none.. The welding gloves are essential as pliers are cumbersome and it's easy to gaul the pipe/fittings as you twist. . For internal surfaces I use a Dremel with a course burr on it. Solder seems to build up there for obvious reasons. It's time intensive any way you want to look at it. One hint: Rap the still hot fitting on a work bench or other safe surface to get as much as the solder off as possible... Thanks for the confirmation...
I was watching a friend of mine trying remove a valve. The only issue was the pipe was still pressurized. The aftermath was the funniest sh.. I had ever seen.
I had a pipe I sat there for 20 min and never did let go. I gave up and stuck the shut off back on. I’ll give it another try and if it doesn’t work I’ll have to call a jackass plumber I guess.
It was. I finally got it eventually . Even though I was downstairs at the lowest point and drained all that out the pipe it went upstairs to another sink also and had water locked in still. I had to go upstairs and open that sink and it let it drain out. I guess it was air locked or whatever you would call it. Kinda like putting your finger on your straw and lifting out of the glass but once you release your finger it drains out.
@@whatfreedom7 That happens to me a lot at work (I'm a "jackass plumber"). There are a lot of reasons a pipe can retain or suck up water and there's no point trying to track the source down after you've shut off the water- what I do is carry a length of 1/4 in. pex tubing, and I suck the water out with my mouth.
@@whatfreedom7 Yeah I've heard of some people taking a little, balled up piece of white bread and sticking it in the pipe to block any water. Supposedly the water pressure will let the bread dissolve and pass through the pipe once the water gets turned back on but I've always been afraid to try that in case it doesn't work and I end up having to cut the pipe open to get the bread out. Idk how you would even think of such a solution. Maybe someone had their lunch out at the same time they had that problem lol.
What about an outdoor faucet (for garden hose) that was soldered onto a 1/2" threaded copper pipe? I'm hoping that the only solder material is on the outside and not between threads.

Can the input/output on transmission radiator be soldered?
I prefer mapp gas for my plumbing needs because it heats up faster and just seems to work better. Especially for larger pipes
Map gas has been discontinued, they use the name for marketing purposes..
@@ostaz007 Yep...Mapp gas and now its replacement are really not that much hotter then propane.
Best to use a plumbers acetylene/air torch.
Thank you! Very informative video!
No problem and thank you for the feedback!
Great video and great information
great video. simple and to the point.
Thank you!
Is there a visual indicator you use to determine when the solder has melted enough to pull off the joint or fitting?
You can sometimes see the solder change from a satin to shinny finish. Typically I just go by experience as the solder can't always be seen if it was a clean joint. Other times you'll see the copper pipe change it's color tone. But neither is like steel where it becomes red when it's excessively hot.
nicely done.
Awesome!! Thanks Buddy!!

If you want to have a reliable joint, it's best to take it apart, clean it, and then resolder the connection.
Your doing it the easy safe way, what about when it's hooked up 5 inches away from the wall ,and the 2 turn off valve?
Use a steal plate to help keep the heat off the wall and keep a spray bottle with water or a fire extinguisher close by.
Cut it out, then resolder with butt joints
Very informative

I came here exactly to see your technique on cleaning inside of a fitting. Grrrrrr
LOL no doubt, he probably doesn't do it. This was for a video, but he probably just buys replacements. The amount of time and effort to clean the fitting would be hard to defend.
After desolder & cleaned can I install a sharkbite
Of course

is it a good ideat o fix a leak talk about that for ahaf hour

Yeah, I didn’t clean the inside of the old fittings & now it’s leaking. 🤦🏿♂️
I had no idea you could reuse old copper pipes, recently threw away hundreds of feet of pipe from our 3 story building.
Easy you don't. Repeated heating and cooling causes hydrogen embrittlement and makes the pipe brittle. Do it once and do it right.

Sounds like there is still water inside the pipe.

Only an absolute novice would solder a threaded joint. That completely negates the reason for the threaded joint.
Why would anyone bother reusing 10-cent fittings and old copper pipe?
What economy are you living in?
Some fittings cost much more, e.g. a 1-inch union
10 cents lol! Browse a hardware store this millennium, great grandpa! They haven't been 10 cents since for about 50 years
