HOW TO BEND COPPER PIPE – OFFSET – Plumbing Tips


– [Voiceover] Plumberparts.co.uk Honest reviews and advice – Hold tight! And welcome to today’s
Plumberparts.co.uk video. I am bursting with excitement today, because I’m gonna show you guys how to do an offset a
really, really easy way. Now, you might be able
to look just over here, you seein’ all this stuff here? This is a bender, this is a 15 mil former, and this is a bit of copper pipe that we’re gonna bend 15 mil size. We’ve already gone over this in our earlier video,
about 90-degree bends. I’ll put a link to that at the end of the video or
in the description below. There’s one thing that you can see here, that is not gonna be part of
this video, it is this vice. Vices do belong on any videos
about bending copper pipe. Cause if you wanna learn how
to do bending the copper pipe, onsite, you aint’ gonna have one of these, unless you’re really lucky. If you’re in a house upstairs
and you’re vice is in the van, I will bet every bit of
money my cat has ever earned that you won’t go to your van and get it because it’s a hassle. So anyway, we’re gonna find out now how to actually bend a set without a vice and I’m gonna use two rulers to do it. If you’ve got two rulers,
this is easy okay? It’s really easy, people get it wrong all the time, how to do sets,
meh, meh, meh, meh, meh. No, it’s easy. Let’s go, you’re gonna
enjoy every minute of it, and I’ve clicked to
early, I’ll click again. Hold tight! The first bend we’re gonna do today, let’s set this to a 40-millimeter offset. First thing you do is get
your pipe in your bender. Now because we’re gonna
be doing a 40-mil offset, which a reasonable amount, we
will do a bend of 45-degrees. Which means the pipe will eventually come round and stick out
along here like that. So before we begin we just
pop our former in here. Right, and then get ready to bend, I’m a get my pen at the ready
I’m gonna bend a 45-degree, so round to there. So I’ve got a 45-degree bend just here, okay so it’s just running
along this line here. Just so we know how far
I actually pulled this I’m a get a pen and I’m
gonna mark on the bottom on the rear side of my 22-mil former. Just gonna run a line across there. And then also sometimes
I’ll put a little arrow on it so I know that’s
the one I’m going on. Right, now move this
back, pop out our former take our bit of pipe
out, and take this away. This is really easy, this bit. Usually, I’ll get my
pipe and actually lay it on this piece here. Right, so what I do now is,
we’re gonna do a 40-mil set. So, I lay my pipe, I get my two rulers, I put one on top and
one on the bottom, okay? Now you wanna hang your
head right over the top, so you’re looking right over it. And just keep pushing that
up until reads about 40-mil. Alright, to make sure we’re
parallel, here and here, Throw this back there, 40-mil
there, 40-mil there, lovely. Using your pen, mark. Have a look over here,
hang your head over here. And take note of where
this runs there and there. And that will run through
the pipe like that, and hang your head right over the top, just make a small mark on the
pipe just there like that. Now we get back out our trusty bender, pop our pipe back in, now you see this mark here that we made a minute ago? We’ll just push that
so it’s just on there. And that will just be touchin’ the top of our runner bar, just here. Now just nip that up,
when I say nip that up I just mean just exert a
tiny little bit of pressure on that so it stops this
pipe from wiggling about. Now most folks onsite, this is what you’re gonna see them doing okay for this bit. They’ll rest the normal arm, the arm that you don’t move, on their hip. And they’ll have a look down the pipe, and they’ll just lift this off, and they’ll just make sure their pipe is in parallel line with
the side of the former. So when you don’t do the bend, it doesn’t wobble when it’s on the table. So let’s do a little wobble
table-test sometimes. A lot of other people
will grab their ruler and lay that across here,
and then they’ll have a look and try and see that it’s parallel. It’s lookin’ pretty parallel. A lot of people also look end-on, to make sure that it’s nice and straight. We just need to move
this back, just a little. Just so it’s just in line
with the top of that there. And then we’re gonna bend it round so this part of the arm here, goes to the line that we’ve drawn just there. Alright so, we’re ready to bend. Just a little bit more. Now just bring it back a
little bit, just like that. And then usin’ our two rulers, we got a ruler on here,
just lay that along there and that makes it so you’ve
got a lovely little 40-set. That’s absolutely solid, beautiful. So there you go, there is
a 40-millimeter offset. Here we’re gonna do an 80-mil offset. So big ol’ 80-mil, okay? Twice the thing, but also
because we have to do the actual offset itself so the bend has to be kept within a
certain constricted space. So, I dunno, you’ve got
a pillar to go around a wall here, and you’ve
come out the wall just here. So you’ve got a go right up round it. We’re gonna put more of a bend on here. We’re gonna go in between
45 and 90 degrees. So, let’s bend away. Bend, bend, bend, bend, bend. And we’re gonna stop about there. Just gonna let that
flex back a little bit. And like we did a minute ago, gonna get my pen and mark that. I’m sure you’re about to see we’re getting a bit of a theme going on here. Right, so get our ruler again, and yet again, just what we
did earlier, nice and easy. What we’re going to do an 80-mil, so at the moment just look at that. Move that up a little bit. Just a little bit of playing around with nothing too drastic. And yet again, hang your head over the top of the piece, take note of these two here and make your mark. Just a little mark in the
middle, just like that. Alright, so that’s slanted
across the top there, we’re just having a look
where that goes across the top of the just the very
area we picked on that rim. Tighten that up. Again, get this up so
it’s right up on your hip. See down on that have
a good look at it okay? Let’s make sure this is right. Nice and straight. Have a look at the other end. I might even get my ruler
out, that across there. They’re looking pretty good, that’s looking pretty
good indeed, mighty fine. Ready for bend. Alright so ready to bend round to our mark that we made earlier. Bend all the way. There we go, just sits there,
look at that, beautiful. Right on that mark. Pop this off. So there we go, the test there. We’ve got a beautiful 90 of 80-mil there. Their both nice and straight, no wobble, beautiful, all done. So, there we go, that’s how you bend a couple a little wee sets. We’ve got a lovely little
40-mil set here, 80-mil set. I mean, as you saw,
it’s not amazingly easy, but it’s not hard if you do practise. Once you get practise,
it’s really, really quick. I think I’ve earned myself
a cup of char as well. If you need anymore help,

  1. morning mate. great videos with great tips and advice. basicly i need you to make me understand this formula :

    radious x 2 x 3.14 
    ————————–
                 4
    i just want to know how to calculate for exampl.
    15 x2 x3.14
    —————–
            4
    i wouldapreciate mate cheers..

  2. I have a very old pipe bender which has measurements around the former arch, mark the pipe with a felt tip and line it up on the set and perfect offsets. It has imperial  and metric and I bought it at a trade fare in the 80s

  3. not disputing you ability,your skills or knowledge and it was a neat peice of pipe bending, as far as bending pipes goes never mind the vice in the van chesnut but 2 rulers come on mate its all about the eye id of drilled 2 pipe drops from ceiling clipped out hung and be half way through piping the 2nd radiator………i think you still need to earn that cup of charr mukka lol

  4. why don't they teach it like this at college….. if id watched this before my final assessment id have flown through it

  5. What is your opinion on soldering pipes in sections and then mounting them? Will the solder break if the pipe is moved and jarred around slightly while installing or does it always have to be done in place? I'm running copper plumbing for an air compressor cooler setup. It's only going to have air and a bit of condensation in the pipes.

  6. can you show us how to pull a semi cross over bend. I have tried watching other videos but they don't seem as easy to follow as yours

  7. Subscribed! Great channel mate, what kind of tube benders do you recommend? I've been looking for a 1/2" (15mm) bender. I wish we did more bending back here in Canada, it's rare, mostly in older houses, but it looks good.

  8. I've found the easiest way to do it is once you've put your first bend in push the pipe all the way into the bender until the black guard or whatever you want to call it just hits the first bend on the pipe, then put in your second bend, don't need rulers etc, anyone else?, currently at college so …

  9. I struggled loads with this at college, gonna try this method next time, hopefully it would cure me of this curse lol Great vid 🙂

  10. im studying to become a plumber just at the beginning stages at the moment. i slightly confused on how to measure pipes, im a better learner when i watch videos and see it please can you make a video where you show how to do measurements more in depth. please can you include all the angles 90 degrees, offsets etc. ill give you a little paragraph from my text book to give you a better idea of how confused i am lol. This is for a 90 degrees bend "First, mark the measured length position. in this example the mark will be 200 mm from the end of the tube. Next, decide on the bending radius. Usually this will be 4 times the tube diameter so, 4 times 2= 88mm.

    Now mark the START of the bending length. The position of this mark is 4 tube diameters (88mm or one bend radius) BACK from the first mark. The last mark required is the END of the bending length. The position of this mark is 2 tube diameters (44 mm or 1/2 a bend radius) FOWARD from the first mark.

    Then insert the correct sized, lubricated spring and bend to the required angle. With a bend radius equal to 4 diameters the 'gain' is 1 tube diameter.

    This is what im confused about its not necessarily how to bend the pipe its the measurements and how to do them. if you could make a video i know after iv watched it a few times i will get it straight away. if you could also make a video on how to bend using bending springs. that will be very helpful as well. hope its not too much to ask and will really appreciate it. thanks

  11. Never normally have a flat surface and two rulers, plus usually working to a tight dead line, I pretty much eyeball all mine which is why they aren't that good. Would love to be a proper plumber where you have time to do the job properly.

  12. Hi !
    thanks for sharing mate, but I got a quicker version 🙂
    To make an offset just choose the length and multiply it to 1.414 which is √2
    Math does everything !!!!!

  13. Hi I'm replacing a single radiator for a double and pipes need to come forward a bit from wall and are coming up out of a concrete floor. I will be draining system off first as a precaution.
    Any advice on how to bend them forward say an inch or inch and a half.
    (Taking valves off heating pipe small iron bar down and gently bend????)
    Please help.

  14. stupid bloody tool, in this day and age you'd think they would come up with something more user friendly.

  15. Now if I can find my language translation applet… Uh well, I'll just guess what you're saying. Four E, four E, what the fuck? Oh 40 I get it! My head hurts from all the "mil" talk, use inches man! You ditched the EU yet you still use their mils.

  16. Nice job but what you refer to as the former is actually called a guide. The former is part of the blending machine which the pipe sits in.nice set though 👌🏻

  17. I see its common practice outside the states, but it seems slower than burning fittings or using press copper? Ill try this sometime.

  18. Great buddies, very helpful. I'm doing my Gas Safe course , three moths left, but I'm having trouble finding a company to complete the assessments with, any tip or advice. Thank Gee of GSD Construction & Maintenance Ltd.

  19. Would it not be quicker to line the pipe up at an angle between the wall and the floor and then stamp on it as hard as you can?

  20. I had to do bends kinda like this today but I used a bendy spring thing. Those benders look way better to use. Ts there a tool u can get to reshape the pipe end after u've cut it so as the spring can insert easier? I had to hacksaw the end off each time and it was a faff.
    Cool vids btw eh mate

  21. Been in the game since 2003 still found this video really helpful! Keep up the great work James boy!! Hold tight!!!

  22. I'd like to thank you for this video. I had a pipe with pinhole leaks needed replacing. It had a 90 degree bend plus an offset, the prospect was quite intimidating, but this video made it look easy – and it was! In fact I think my pipe was a better fit for the space than the old one I took out! There's not enough real plumbers in my area – so they don't even return your calls.

  23. Great Vid! But I'll bet you all the money my cats ever earnt that the part you are calling a 15mm former is actually a 15mm guide…every days a school day.

  24. Jobs specifications don't allow change in directions utilizing bending……

    All, even in the UK, job specifications require change in directions with fittings.

  25. I am taking my bathroom assessment very soon, and I've got to pipe a pedestal basin. Please can we have a video on how to do it?

  26. Hey Plumberparts, I've just bought my first pipe bender it already has the 45 & 90 written on it ( you've written yours on) do i bend on exactly 45 on the bender or just before? thanks . hope this made sense haha

  27. Hi James. Annoyingly my bender dosnt' have any 45, 50, and 90 degree markings. I'm using a template and bevel to get the correct 40m measurement in the way i was shown at college. I place the side of the bevel along the centre of the pipe and carefully make the bend. But when I feel the the pipe is in-line with the bevel it looks like the pipe is no way near the same area on the former that yours is. Is this down to different types of formers and makes of benders? Ill admit that I did buy mine cheap from ebay. Many thanks.

  28. @plumberparts Love the videos and have learnt a lot from you so thanks for that but I am struggling with this…. How do you bend a shallow offset of less than 15mm in 15mm pipe over a short distance of around 50mm? Have a decent pipe bender and tried many ways but all I have is a pile of scrap!

  29. I had to replace an imperial 1330mm rad with a 1200mm. extensions are handy but the offset is 50mm. the pipes are concreted in & cant be moved. can we do a short 50mm offset change over a 100mm length or would I be better with elbows from the pipe ?? Thanks

  30. I've no idea about plumbing and couldn't understand the markings. A sign of a good instructional video is anyone can understand it. This is the 3rd video I've watched and still don't understand the markings.

  31. What about a measured length? How do you get the bend in the correct place. That's what's blagged by head tonight at college

  32. I’m doing plumbing at the moment at college and that’s the one thing that gets me I can do the whole thing then the offset fucks me over . I over bend it and put me out on the whole thing I did . Tutor made me do it all again . Can you do some more of those with other measurements video was really helpful

  33. Hi there! I'm a carpenter / multi skill looking to become a certified plumber. I'm currently self employed so what are the best options for me? I cannot afford the time off work to do full time in college for 2 years… are there any intense courses that would work?

    Cheers

  34. Links to the tools I use everyday here: https://www.amazon.co.uk/shop/plumberparts

    Plus, follow my Vlog “TimesWithJames”: http://www.youtube.com/c/timeswithjames

  35. What’s the secret to not ever kinking the pipe? Even going slow, or avoiding stop starting it can go sour.. any tips?

  36. Loving these pipe bending videos, I'm learning this all at college at the moment but it's taught very different, and it's fine, but as soon as you've done it, you completely forget the way you done it, because they don't give you simple easy bullet points like this. I've wasted so much pipe today working out how to do certain bends I wasn't sure of, and now I've seen your videos its making much more sense. Please do video's on all the other college taught bends to, very very helpful!!!
