Reheating PVC to the point where it melts significantly reduces the strength of the "Heat Affected Zone". Might work for a while under low pressure. If you want it to last buy a 3/4" NPT to 3/4" pipe PVC fitting for $0.45
I did this ALOT in the past for many plumbing companies. They have all ended up with financial problems n I now own a company doing flood damage restorations
When I was studying to become a plumber. My teacher said that in this occupation, I will never be out of work. 35 years later, and with these "fix" videos it has never been as relevant as now.
If it makes you feel better, I rolled my eyes instantly at that one and wondered how they got the threads so perfect and I am not a plumber in any way shape or form.
Maybe someone here has already addressed this incorrect short-cut. But, when plastic piping/tubing is heated like this the molecular chains are softened and will allow breakage with less than stated forces. So just stop taking short-cuts. Use the correct materials and tools called for in the job.
I was sholl thinking to myself if he heats up the medal then stick the plastic tube in and pull it out want that jus push molded plastic to the top instead of forming the correct mold for the turning thing lol I’m no contractor but even I peeped that
@cmbwaldo1417 You're absolutely right. Threads doesnt magically appear. The pipe would just get smooshed and get the inner diameter of the threads, but moat likely it would just buckle. This video is garbage
Looks like he used electrical conduit to me. More heat resistant than pvc. But still stupid. Besides, oron pipe for water lines went away 75 yeas ago in America
Do you not know how moulds work? He basically just used the threaded coupling as a plastic mould. That part works exactly as shown in the video. The actual problem with this is the fact that the PVC pipe is going to now fail under pressure after it had been modified by the heat.
@@matKilla9801 why yes i do, i work im plastic injection moulding Shoving hot plastic into a threaded mold without somthing to press the hot plastic into the threads will not allow the threads to take its shape Also, themoplastics repolymerize when cooled, so no, it being heated will not make it fail more than before I hope you learned from this
@@KERL99 To explain to you, pipes are made very tight and precise so they can withstand pressure. The Heat on the PVC expand molecules, so heating it will basically deform the pipe and affect it's integrity on the joint point... What happens if you run Pressured Water in a deformed pipe? Well, let's just say you will have a very fun time trying to explain to your insurance company what happened. That is why there are male/female adapters, and why pipes have specific sizes, that are standard measures in the entire world.
@@Killer1986Chris what is the most prestigious job in the world at first? Some could think to actor/actress, singner, be the owner of Space X, ..... but if you whant to make a link with the vidéo and speak about plumber, yes I know I made my class in that domain
@@herculesrockefeller1683 as a mature adult you should not be licensed to be this dumb 😂😂😂 you got phd in dumbassary or something? cause i fully believe you if you do 😂, go back in 3rd grade so you can start learning the words "sarcasm" and "jokes"
Yes, there’s a simple method to connect PVC pipe to steel, it’s called a threaded adapter. Comes in male or female threads. Glues right onto your PVC pipe. Easy peasy!
@@jono8588 It's the being right part... More than often construction workers have an ego as huge as my cock, so they tend to have problems swallowing... Their pride... Jajajaja Jokes aside, yes, being corrected by others with BOOK KNOWLEDGE is annoying, by someone that has done the job for 20 years and can guarantee a good work vs learn anew technique in which they need to learn again
Any kind? That's a little hyperbolic don't you think? I understand that you're being hyperbolic to protect ignorant people but it would be better if you were more accurate. It will hold pressure, but neither of us can say how much without testing. Personally I wouldn't try using this technique for anything over 10-15 psi or for any pipe greater than an inch.
@@Random_dancingwhere in this video does it say that it doesn't so if you're not an electrician or a plumber you probably wouldn't know what the difference in the pipes are for
Yes u and i r about the only 2 people who noticed that why ???? Great minds think alike and never get burnt or ripped off in life if we stop and think ( analyze ) the situation were in
I'm in the middle of making me a two man sub to go down to the titanic. Running my pipes this way will save me a whole hell alot of time. Thanks for the tip
As a lawyer i can assure you even i have more integrity than that joint. Edit: Id like to say thank you for over 2.5k likes. Ive never had so many likes in my career lol.
For that "wisdom" you don´t have to be a plumber. Just using your brains will make you see an be like "how on earth will de thread be made while pushing the pipe downwards??"
Всё правильно говорите. Не только резьбы не будет на пластиковой трубе, но и непонятно, как при разогреве бронзовой муфты не сгорело уплотнение между трубой снизу и муфтой.
As a mildly sophisticated man of poor taste and quality, I can confirm that this is fundamentally a necessary practice when trying to pretend like you know what you're doing...
Not true that’s actually good for a condensate line here in America 🇺🇸, I don’t know about Russia if you guys got like condensation drain lines I wouldn’t put that under high-pressure 😂, I’ve never seen it but I like the idea
It's not something you would do in the house, but you do notice it's outside? Possibly making a sprinkler that won't be under the full pressure of the main waterlines.
I’m a landlord and this sketched me out, I don’t want my tenants getting hurt just hire the pro eat the cost and make sure the people living in your house are safe it’s not that hard.
As a wife to a Non Plumber, who replaced all the pipes in the kitchen, can almost certainly say he probably used this hack because we had to replace all the pipes in the kitchen a month after he replaced them all! lmao and yes we had a plumber do it the 2nd time lol
I love the plumber community, they’re always so creative in demolishing the person who makes horrible ideas like these, much like how it would demolish a house with water damage if it was ever used
Would be More Believable if not 3 Clips Spliced. It may work, I believe if you don't try it, you can't say it won't work. Video without any Breaks would look more Believable
Its not a pressure fluid connection, its an outside conduit for electrical wiring. That's what the ptfe tape is for. I spent about 25 years in engineering. One of the best pieces of advice I have is to pay attention to the details.
... it's not tho? For electrical wiring you would use PVC, HDPE, PP, or any other material that ISN'T CONDUCTIVE, not a steel pipe...and even if you were right, what does that change? No matter the installation type, you still gotta connect the pipes propetly and not with some DIY tricks
@@mrjaku633 Even if I was right? Son, first off, calm down. Now what did I say incorrectly? Of course you would use proper materials. This video, however, is not using proper materials. If this is, as I assume, a simple romex jacket or something (agreeing w/you about conductivity, etc), then this simple thread trick is decent. If it works, it works. If this is a pressure fluid connection, then im at a loss for words... Most of my career has been hydraulic control systems. Why are you cussing? Your generation has the thickest heads and thinnest skin.
As a person who once had a dream about seeing a picture of the reflection of the shadow of a plumber, I’m 100% certain that this may or may not work. And I stand by my assertion on this.
Water pressure can be anywhere from 65 to 100 psi. Easily able to crack a heated and manipulated PVC and put someone’s eye out, so yeah two psi would be the max I would ever use something like this at which is basically saying don’t do it it’s not worth it. People get misled on things like this and they end up getting into trouble because they don’t know any better. People! don’t be showing hacks that can cause harm to people who are just not smart enough to not do it. You are risking their lives!
That’s actually fair. If it was a survival situation this would be great for the short duration. Guarantee this dude actually does this on real houses as a licensed plumber 😂
That shit dont work lol if you're in a survival situation and think this is gonna work/help you whatsoever just hang it up at that point right there lol you aren't gonna make it much farther anyways
Oh damn, I've been watching several videos about pipes like this in different ways of connecting them and every single of them has your exact comment about how its not safe. Im wondering, how to do that safely? Genuinely asking...
Lots of people saying it gets brittle with heat aren't correct. PVC is a thermoplastic and repolymerizes as it cools. Plumbing code in the US even recognizes this fact because pressure ratings on PVC are assumed to be at an operating temperature of 73°F. If you're going to be using higher temps, you have to derate and keep pressures lower. Max allowable operating temp for PVC is 140°F. Beyond that temp, you need to use a different material. However, PVC regains its pressure rating once the operating temp drops back down. The big issue with this hack is that threaded PVC pipe fittings are thicker in the threaded area than a standard segment of pipe. Doing something like this, the failure mode isn't going to be the heat used to mold the threads, it's going to be the threaded area being too thin to hold pressure.
1. Thats not a PVC pipe, thats a PPR pipe. 2. PVC will never melt like that and doesnt look like that 3. PPR is meant to melt like that cause thats how you fuse them together 4. This might actually work, safely, despite what everyone is saying, but i have my doubts that it got such a nice thread from pushing it down. i would screw it on the metal thread instead.
Yes, you are right. This is a PPR pipe and not a PVC pipe👍 I also tried screwing it in, but the thread didn't work out well. so pressing is the best option.🤗
@@Simple_Creative now that i think about it a little, i guess its fully molten, and you basically push it into shape, as a press would mould molten plastic. Does it affect the inner core structure?
This is not possible. Nail down force will only make uniform circular thinning of PVC. As Melting pvc cannot expand without pressure gradient from inner side, male thread woll not be carved at all. A rotating gradual plunging might help create threads exactly according to outer coupler but that too is not possible as that high temperature is difficult to achieve as a steady state temperature for the time taken for skrewing in ..
As a Martian, I can confidently say that this advanced technology came to Earth from Mars. This was one of the main reasons why our civilization ceased to exist and our planet died. So, do it at your own risk, you have been warned!
pvc 파이프에 열이 가해져서 아래나 위로 밀려난 부분은 그만큼 얇아지고 강도도 약해져서 작은 충격에도 바로 부러집니다. 저 조그만 금색 부분이 커플링이라는건데 3/4 이라고 적혀있네요 직경이 3/4 인치 사이즈인데 그냥 거기에 맞는 pvc파이프 구해서 시공하는게 가장 알맞습니다.
It might be okay for a quick fix as long as there not much pressure on it but the minute any kinda good pressure continually starts flowing thru it ,it's gonna turn into a damn giser lol
@@ronaldraymondhutchinson8569PRESSURE?? HOW MUCH PRESSURE RUNS THRU WIRE?? BC THAT'S WHAT HE RUNNING NOT WATER...U GUYS GOT IT ALL FIGURED OUT THO EH...?
Yes, it works... I saw it on MacGyver in 1986, and it saved a village from a flood. He didn't have Teflon tape, so he chewed gum 13 chews and stretched over the threads.
Ok I'll just explain to you the flaws instead of debating Flaw no. One - It won't be able to hold the water pressure because of becoming thin at the joint and would probably break. Flaw no. Two - If it is for the electrical circuit then the joint will be very weak and there would be high risk of breaking at some point of time.
Yeah this joint would absolutely break. For electrical it wouldn't be the end of the world but it's definitely an idiot's practice to do this, when the correct way is really not much harder
