Thank you. Not only did you present the necessary information, quickly and concisely, without taking us back to the year 336 B.C. for the history of plumbing, but you told us the useful tidbits that all plumbers would assume, but us DIYers might not know, and even your own useful trick. Thank you again.
😁😇
Another good one. I don't think I've tossed a fitting in 40 years. Sound cheap but it has saved me a lot of trip to the hardware store when I have a problem. Even short sections of straight pipe comes in handy.
Totally, I find it fun to remove fittings and shining them after and it doesn't even show ;)
Well sir. Not sure if you read your comments at all. But 4 years ago when you posted this, I just got started in the plumbing trade. I took this comment to heart and tried to reuse as many fittings as I can. Saves me and my customers a lot of time and money. Thank you.
@@jackmyhre8759 I just happened to sit down and got online when your comment came in. You made my day. Anytime I can help someone, especially one the actually works for a living, gives me a good feeling. Best of luck to you in your business, this country is rapidly running out of people that can fix things.
This saved me in multiple ways. During the third wave of the pandemic in our location, hardware stores were closed except for curbside pickup and I didn't have a spare shutoff or the patience to wait. Also, I keep wasting perfectly useful valves and over time these costs add up. Additionally, gave me the confidence I needed to know I was taking a valid approach (at least by one other, more I'm sure). Thank you, these videos are great.
You are very welcome Brian!!!
Thanks again for the information. I've seen plenty of your videos that I feel confident on doing this but never hurts to watch another as a refresher. 😊🔧
👌👌👌
You have some really good videos and information, for both beginners and pros. Thanks!
Got2Learn, you have an excellent way of explaining the steps in your videos and very good videos to show how to do it....you have also added your experience in most videos which is very useful in knowing what could go wrong, before you start.....thank you
🙏🙏🙏
I like that your videos explain a lot more than the tricks video.
I'm glad you like nido, thanks for the nice comment and please share ;)
Do you have to sand the pipe you unsoldered before soldering it back together?
No, just do the change quickly!
Thanks for the tip! Coming in very handy once again. Keep up the superb content!
You are welcome ;)

I like to wipe the old pipe off with a dry rag or some toilet paper while the solder is still in liquid form. Then you can start with a solder free pipe and clean it and flux it properly.
Good tip, thanks Drew!
Great video... need to replace outside fitting... the pre prep will save time for sure.thax
Right on
Great videos on soldering, concise ,complete
Thanks 👍
Génial! Merci pour ces instructions très bien expliqué.😉
Plaisir!
Simple and to the point video
Thank you my brotha !!
You're welcome!!!
hey thanks for all these videos - they are very informative!
Awesome, you are welcome!!
Hi. I made a mistake and I have a 45 degree copper elbow sticking out of plane by 30 degrees. I was hoping to heat it and rotate it into position but don’t know if the joint will hold compressed air afterwards. Can you advise me?
Love your videos by the way. My soldering has improved ten fold after watching them.
Thanks,
Paul
Great video about unsolder fittings. I watched also your how to solder and i liked both of them.
😇😇😇
Your videos are so good, better than the work of most instructional designers
Glad you like them!
Thanks for the tip
It did came in handy 👍
Glad it helped, thanks Jose!
Great explanation. Loving it!
🤗🤗🤗
I have to extend my 1/2in. copper pipe to install a new tube faucet so can I use this method? And if so do I need to remove the elbow or can I just remove the horizontal pipe without compromising the vertical solder joint?
Thank you! Just replaced my first leaking spigot with your videos
Awesome, good job Flavio, glad I could help out!
Way to Go!! Thanks!!
Thanks for watching!!!
Thanks for the video
You bet!!!

Great info! Love the channel! I watched your recommended video “How to Solder Copper Pipe the Correct Way” and I am a bit confused to why in this video you didn’t take off the shut off valve and then sand the thin layer of solder on the copper pipe then add flux like you did in the other video. I’m not a professional, this is an actual question that has been boggling my brain. I’m sure it’s just something that I missed. I am trying to fix my shut off valve for my toilet and I just want to get it right.
The flux was in the new valve 😉
Spot on comment, hack away
I just had to do this Yesterday. The part about get all the water out of the pipe is definetly the key. Any water in the pipe will male it extremely difficult for the joint to solidify
I have to play a plumber for my outside sprinkle system. I need to unsolder two fittings. But I can't reattach one side until I change out a stop valve- can I just clean up the copper pipe and solder normally?
Great videos, i have a 90 degree elbow that i need to turn about 1/8 turn. i want to heat up the soldered joint and rotate it. should i be able to simply heat up the joint till it moves then rotate it and allow the joint to cool back down or do i need to take it apart, clean, flux, re solder in order to get the 1/8 rotation that i want.
I don't recommend just heating it up and rotating it, this can introduce oxides in the joint and cause it to leak, take the time to undo it and solder it back up again, like this you are sure you won't have problems down the road. Here's a good example of what I am talking about: ruclips.net/video/8IV7oG43DZ0/видео.html
Do you preheat the new fitting? It looks in the video like you are putting a new cold fitting right onto the pipe after removing the old fitting. I assume you heat it some more and add more solder?
Yes, you gotta heat it once it's on or the solder won't melt ;)
Thank you
🤘
Thanks!
🤘🤘🤘
I need to do this to adjust the angle of the fitting, can I just heat it, adjust and leave to set or should I apply new solder?
I would remove, clean fitting and pipe, then solder it back on as there's no flux to prevent oxidation.
I guess I'm late to the party. But you don't have to sand down the copper line before adding new solder/angle stop?
i am going to rebuild a heat on demand unit, with solder withstand the heat that the electric elements create to heat the water in copper tube or would it have to be brazed
The water will conduct most of the heat out and act as a "heatsink" if you want, so, just solder is fine ;)
What is the trick for removing endcaps? They seem to always be stuck on really well and deform really easily when heated...
I understand the reason why you need the the pipe dry when sweating two pieces together and it affecting the solder's ability to stick to the copper, but why do you need to do it when de-soldering? Great vid by the way, helped me decide to go ahead and cut it, have plenty of room.
Because to unsolder, you need to melt the solder to remove your fitting, the solder cannot melt if there is water in the pipe ;)
@@Got2Learn Makes total sense, thanks for quick reply! Just got done with the new shut off, used compression fitting with the little gold ferrule ring. Found out on old pipes gotta use that thread tape, or you can get a tiny drip no matter how tight you make it..lol.
Good job man..
@@Got2Learn My Dad taught me to stuff a piece of white bread in the pipe and solder away. Then the bread dissolves later on.
Can desolder if can't stop the leak, and if the copper pipe is short coming out of wall need 2 cut with a thinner saw, 2 push on a sharkbite ,and just make it.!?
Do you have to add new flux to the copper pipe before adding the old fitting?
I had flux in the valve socket, I didn't say it in the video and I should have, but yes, you need to add flux.
Yeah I had a fitting I sat there for no joke 20 min straight and never would let go. I gave up and just stuck my damn shut off back on. I’ll have to try again but I really don’t want to cut back further cause then I have to get into a 90 going into a t fitting which is a whole lot more trouble. If I can’t get it to let go on the second go I’ll have to call a plumber out. What’s crazy is I just did the same thing on the other shut off line and within a minute or two it came right off.
Great video!, I missed something, don't I need flux to solder the new piece?
Just put it in the new valve and you'll be good ;)
That's the exact question I was going to ask if I should have clean the old solder off roughed it up and fluxed it but it seems like if you put enough flux on the new fitting that will transfer to the old one and being that it's tinned the Sauder would stick I did it the other day and I don't have a leak but after talking to a plumber at a Home Depot and him telling me I should have wiped off the old solder roughed it up and fluxed the old pipe before I put the new one on it started making me second-guess myself
I have an old Delta shower valve that was connected with Qest Tubing. I removed the old supply lines and would like to sweat copper to the valve body, but the copper tubing fits very loosly in the socket. Should I still use the valve body? Is it okay to fill the gap with solder? Thanks.
Never
Do you need to apply flux on ball valve before soldering back to copper pipe?
Yes!
I noticed that he attached the new prepped fitting to the old unprepped pipe. Is this normal, effective? Is it ok to do this without prepping (cleaning/fluxing) the old pipe beforehand?
I just was going to ask the same thing. surely you need to prep the pipe too and not just the fitting :O
I don't think jamming the new valve immediately onto the old uncleaned pipe is a good practice at all. Soldering a pipe into a socket is not just a matter of filling the gap with solder. The process needs to create a chemical and metallurgical bond between the metals. The solder will re-bond with the pipe but will not bond to the inside of the cold valve that is pushed on, unless you continue to heat the valve until its's socket is hot enough to bond with the solder.
Would you recommend replacing a soldered fitting (after removing it with your handy method described in this video, of course) with a compression fitting or nah?
You could, but I prefer soldering it.
What temperature is that torch? Can I use a $30 propane torch, like from Home Depot?
Sure.
So you don't have to clean up the de-soldered copper before installing the new fitting?
Are you putting flux in the new fitting before switching it out after old one is heated and removed?
Yeah
I had an elbow today that I don't know what that thing was so stuck for, but it took forever to get off and I drained all the water done everything like I've done before, and it refused to come apart forever. I had to end up, beating it with a hammer while having a vice grip on the joint and it finally broke free. And it was to the point where it was smoking hot by that point.
I've unsoldered plenty of copper fittings but am on a job right now in close quarters at a hotel and I want to unsolder some 1 1/4" copper out of a brass 1 1/4" ball valve. Feeling a little hesitant man, what say you?
I remember having to do that and I felt quite hesitant as well, but never did the valve unsolder on the live side, so you should be fine. The way I see it is as you are heating the "non-live" side, some of the heat is going towards the "live" side which is totally normal, but that small amount of heat that does go to the "live" side is mostly absorbed by the water in the pipe, so by the time you get the pipe out, the "live" joint won't even have come close to reaching the "un-soldering" temperature, is that ok for you?
Any tips on a super oxidized shutoff? Do you just clean the heck out of it before desoldering?
Yeah remove the most you can, than un solder.
@@Got2Learn thanks! Also your videos are very informative and helpful. Cheers!
;)
Should we use a similar amount of solder compared to if it was a new joint? I say because there's already old solder on there.
When he says to "prep the joint", why does one side of the coupling need to be sanded and fluxed, while the other side is already ready to go? Just curious if both sides need to be prepped.
Would a heat gun work to remove? even though it would take longer?, I am sure I can do the torch but wondering
It would take way too long if it did work.
@@Got2Learn thank you for your reply, have gotten many things done watching your videos
Awesome!!!!
I never thought of just slapping the new fitting on, always cleaned the pipe and started over
as long as you flux it and it clean of debris it's fine.
So, no need to add flux on the joint with existing solder on it?
Do you need to re-apply flux to the new joint?
Yes, I recommend it.
Got2Learn Thank you! Great channel.
@@Got2Learn from the video, it looks like you apply flux to the new fitting that you want to attach to the existing pipe section (which is what you meant in the video when you referred to prepping the new fitting). the existing pipe section already has solder on it, so i assume that you do not apply flux to the existing pipe section. am i correct in this?
@@paperwait9611 correct I don't think you would need to apply on the old fitting since it have solder already
How 2 unsolder very near a gate shutoff valve without damaging gaskets?
I just replaced my toilet supply valve. The valve broke and would not drain. Sweat valve. I needed the pipe length so could nut cut the pipe. I used an angle grinder to cut the valve in half to preserve pipe and drain water..... then I sweat new valve on
Nice work!
Will it not melt the nylon seal incide
Gotta be quick ;)
Why does it take so long for me to unsolder certain fittings? I’ve heard the pipe should be slightly sanded as the oxidized pipe takes longer to warm up?
Is there remaining water in the pipes?
Got2Learn Can’t really tell? Maybe this is why it’s taking so long?
Yes, most probably.
Got2Learn Finally got it off... and yes plenty of water in it as you said! 🙏 Thank you! Any ideas on how to drain water better?
You can use a shopvac to get the excess water out by blowing it or sucking it, it helps.
Shouldnt you clean the pipe before resoldering?
Nope! Only the new fitting needs to be clean so the solder adheres to the copper fitting, but you can leave the dirty copper pipe, dirty. Hope this helps!!! ☺️😉
I'm trying to de-solder my outside faucet but it won't un-solder itself! I put heat to it and it just won't budge.
What do I need to do?
Have you emptied all the water inside the pipe?
@@Got2Learn no I had not but also wondering how I do that? Where I need to get is about 12" in the pipe.
Ok guess I'll try to eliminate the water as much as possible. But will take any Information you can give me. Thanks
If you can't suck it out with a shopvac (wet/dry), you can push the water out by blowing the air into a closeby faucet and opening the outdoor faucet, it should come out, try that.
I get rid of the water by turning all the radiators off by the valves, then on the pipe I'm working on I will turn those valves on and just have a bucket for the water to go into. Then take that valve off when the water stops coming out and will have no water in the pipe.
Thanks all I ended up putting a valve just above where I was working and when that did stop the water then I used something I never thought of I stuffed the pipe with a SMALL piece of bread. After that everything was a breeze. Turned the water on the bread shot out of the pipe. Done! Thanks for all the good feedback.
My bathroom sink faucet is now a pouring leak... I bought a new faucet came with compression hoses & connectors etc. Cost so much now... I asked my older male room mate to please put it on.... It is now 4 months later and he hasn't done it! 0.0 live in southern California and have always been frugal with water. probably over 50+ gallons a day going down the drain. He was a pipefitter at Gen Dynamics spot welder on ships for GODS SAKE, he said that the copper pipes are soldered onto the faucet I said so cut them off and there is self screwing ends that included in the facet kit.... I NEED SOME HELP BECAUSE HE WON'T FIX IT. HE IS NOT WORKING SO BEING TIRED AFTER WORK IS NOT AN EXCUSE. I understand first thing I do turn off water which would be the main water outside, I own this 1965 mobile home and I am having a feeling everything needs replacing. Should I put hot cold shut off valves under the sink while I am doing this? Lived her 23 years the faucet is unfixable as I believe it is the original the valve is no longer available...Thus the new faucet and kit.
Will this work for a valve fitting that has been soldered to the copper pipe for 40 years?
Of course ;)
Of course this will.
Please, I have a question🙏In another video, you advised to apply some lead free solder paste before soldering, but here at 1.46, you did not apply it! Thank you for this video!🙇♀
I applied some in the fitting before putting it on.
@@Got2Learn Wow! Thank you for your lightning advice-answer! Now it's all clear in my mind now!🙏🙇😍🥰
@@mobilove 🥰
Love your videos. Always on point. I have an old tap that needs to be desoldered. Should I remove the guts first or just heat the connection as usual ? Thinking the heat might damage the o rings.
Don't need to but be careful!
@@Got2Learn ok thanks
thank god you use CANADIAN MADE (in toronto) DAHL. valves. thats all i use for my bathroom installs. I hate brasscraft. lates
Brass craft angle stops are the best. Just not the ones from ace
No. Canadian made Dahl are the best. Brass craft lol. Fuck no. Dahl baby.
I just didn't understand 1 thing, why you didn't clean and debur the pipe before soldering the new fitting?
How long does it take to heat up enough to remove? Just curious as to what to expect
Depends the size
I want to unsolder/solder to replace a main gate valve with a ball valve but it's only 3/4" distance from an elbow. How can I do this without loosening the 3/4" length pipe at the elbow? Would a wet towel and vise grips be enough to absorb heat? This is what I have indirection of water flow: ELBOW - 8"PIPE - GATEVALVE - 3/4"PIPE - ELBOW. Thanks so much. Great series of videos! postimg&cc@SjhqfrxS Replace & with . and @ with /
postimgDOTcc/SjhqfrxS
Wrap the elbow with a wet rag, that'll keep it cool enough for you to finish unsoldering, do the same when soldering.
@@Got2Learn OK. Thanks so much! I seen your other videos on how to absorb heat, but figured this distance was too close. I can just cut the pipe on the other side of the gate valve because the ball valve body is much longer. Thanks!!
@@rgraz4929 it's pretty close but can be done.
I generally avoid de-soldering unless I have to. Fittings are cheap.
Sometimes you have no choice.
@@Got2Learn Yes, I have encountered those situations. Not fun.
Lets see how you do on 3/4 and 1 inch. I want to see you do that. Half inch is easy.
Are you implying that you can't unsolder 3/4" fittings?
Reading comments at 2 am r you. Lol.
Can't sleep ;)
How come you don't have to remove the old solder and sand?
If you have water in the pipe
How are you going to unsolder it ?

الكلام اللى بتقوله أكتبه على الشاشه وانا أترجمه
Question1) when you unsoldered the old fitting, then immediately put your new prepped fitting to the pipe, I noticed you did not put flux on the pipe, aren’t you supposed to? Will it hold?
Question 2) I’ve never in the past been able to remove solder from a copper pipe with sand paper (I’ve always used the plumbing sand paper-the red tape one) , So I always used the torch to remove excess solder from a pipe. Are u saying you can sand paper solder right off? Not sure why it’s never worked for me before
Question 3) I always tough when a copper pipe was greyish/sylverish That it was not good anymore. I figure now by your clip you can still use such a pipe . What is the greying on the pipe?
Last question: how long can a copper pipe last in a house? Or a residential copper pipe system? I know 50 years for sure. When should you change such pipes in a home?
Thanks for the vids. They are very informative
Can I install a shark bite with unsolder pipe
Only if you can get the pipe PERFECTLY clean, or else you need to use some other fitting.
A leaky gate valve that is.
What if your copper pipe was welded, not soder together. RIP.
Welded copper?
@@Got2Learn Was trying to desolder a copper pipe..and its not coming off or getting lose at all. I'm guessing it was welded ?
@@dthao227 no no, maybe brazed.
@@Got2Learn how do you get that lose or to come off?
@@dthao227 cut it 👌
