Press fit and MLCP pipe. My name's Allen Hart and in today's video, I've got one of our moderators on the plumbing and gas training group. He's done a video and he's going to explain press fit, press fit copper, he's going to show you the different guns. He's also got some MLCP pipe as well, and he's going to give you his opinion on that. He's called Nick, amazing guy. His work is absolutely spot on, the best, top of his game, to be honest. I'm going to be going out with him in a few weeks time, so we'll have some more videos on here of some of his work, and you'll be amazed at how good he is. But without further ado, I'll pass you over to Nick's video.
Right fellows, as requested, or as I would try to ... This is going to be very quick, I'm not going to bore you with the technical details, but that's a Novopress gun. It's, as I say, if you see the Geberit one or the Milwaukee one that's in the picture on this thread, it's made by Novopress. This is an M Press Jaw. You see where it says M there? M-Profile, that's a 15 mm. They're dead easy to get out. Out, in, that's it basically. 22 mm one, that's it. Dead easy to change. Yes, you need a jaw for every pipe. This little gun here will go up to 35 mm or inch-and-a-quarter in old money. This will do copper, stainless and carbon with these jaws on the M Press Jaw. Right. I'm going to stick the 15 mm back in and then I'll show you later.
This is a Uponor gun. This is for your composite pipe, same principle. Made by Klauke this, German company. Competitor to that one. If you notice the difference, they're longer by a section. These jaws won't go in there and them jaw won't go in here. It's brand-specific. You can get the jaw for the composite pipe on the U-Profile to go in this gun. Right, I'll shift this out of the way and we'll put some fittings out. Fittings, copper fittings ... These are for water. They're 16 bar, rated up to 110 degrees. These are available up to four-inch and they do a stainless version up to six-inch as well, which is 154 mm. I'll try and put some pictures on later. Dead simple, dead quick. Obviously, know how it works. That fits in there, pipe goes in there, you press the button.
Right, what did I do with my pipe? So pipe, normal cut with pipe slice. There is a reaming tool that you take the burr out of; they recommend you do that. And then you need to ScotchBrite it, clean it all up. Check the end of the pipe, make sure there's no major scuffs and dings and dents in it. Now you need to take this, depth gauge. You put it in there and then you would mark the depths with the proprietary pen. I haven't got a pen. I'll be honest with you, fellows, this just doesn't get done on domestic jobs. Commercial jobs, it will do because to get it signed off for the warranty they have to be IDed. You should do it on all jobs. We don't, I'll be honest with you. We've never had one leak yet, and using it for five years.
That would go on there, all the way in. The line would indicate it's all the way up. You stick it on the end of there, on the finger, let go of the button. Machine runs its cycle, take it off. Now it can leave a little tag. There is a product called Drislide that you're supposed to put on there. I haven't done that just yet, but you don't normally leave that. If it's tagging now there like that, you take a file and file it off. That's it, finished. Done. Okay? That's that.
So moving on to the composite one. Same principle. This is a U-Profile Jaw, so this will do Uponor, Rifeng, Multipipe, Maincor, and there's a couple of others. Okay? Different size now, 16 mm. So this is the pipe. It's a composite pipe with an aluminium core in it, so it's got an outer layer, an aluminium and an inner layer. It's 100% oxygen-free. Oxygen can't get through it or out of it. Different process now.
Now, now you're going to seal the fitting on the inside of the pipe. So you're not bothered what the state of this pipe's on the outside. If it's scratched, a bit dirty, it's not a problem. Your push-fit pipe, you've got a major issue if it's got a big scratch in it because the o-ring's got to fill a gap once you fill it up with water. So I'll show you how to do that now. This is a speed reamer. These come in different sizes now. What you've got to be aware of is that these are brand-specific for the pipe because the pipe can be different wall thickness. The outside diameter will be the same, but the inside diameter may not.
So good old drill, sorry it's not a Festool one. Speed reamer goes in the end, and all you're doing is reforming the pipe round and you're putting a little chamfer on the inside and a chamfer on the outside. This is your fitting. These are an all-metal one. This happens to be a Rifeng one, that's a Multipipe one. It's plastic, it's composite. They're double o-ring sealed. - Навчання та стиль

Excellent as always Alan. That waste for the bath trying to run uphill in the flexie joint really creased me up.
Thank you so much for watching it all😂😂😂
For a guy that doesn't do a lot of installs, this is very informative. Thanks
Thanks for watching and commenting. Any questions just ask👍
Good video Allen, "press fit all day long" for me. Well done Nick
JK 👍👍👍
Glad you could make some use of it. 👍
Keep sending them. Thanks so much.
Good video, very helpful for those new or thinking about press fitting
Did you see the pictures at the end? Thanks
@@AllenHart999 probably more than I spotted, no tundish and undersized discharge pipework from unvented, expansion on hot outlet, heating vessel doesn't look secured, fluff build up inside guaze filter on bbu burner, and everything wrong with that waste pipe 😂
Great video Allen.
I agree never use push fit.i done my C&G in the 60's.my mate recently had a leak under his bath it looked like spagetti junction i didnt know where to start with these new builds. In my day pipes had to be properly supported and straight or as a apprentice i would get a thick ear. Im amazed how quick they can plumb a house these days but to me its shoddy work most of the time.
Thanks for the comment.
Great vid, I just started using press fittings with a new company. It's definitely quick, but with tricky runs in older domestic properties planning my pipe run and what order I'll press the fittings in has been the toughest part of the learning curve.
Would you want to go back? I know I wouldn’t. Thank so much for the comment.
@@AllenHart999 cheers Alan, I don't think it's a case of going back, for most jobs it's great, for some I prefer the way soldered joints look, which is totally aesthetic.
Good job 👍 mate
Thanks
Great video. One question, is all MLCP pipe compatible with all brands of fittings? for example, can you use uponor pipe with tweetop fittings?
I use Blansol MLCP fittings Thanks.
Hi Alan great vid as always👍I have the Geberit press fit gun. Do you know if you can get jaws for it to do the composite pipe?
Yes you can. I use Hilti jaws in mine. Thanks
@@AllenHart999 thanks Alan 👍
Where do you buy mlcp pipe and fittings from?
Why you don't reply to messages? I just would like to know if there is a press tool that just by swapping jaws can do multilayer and copper and if there are adaptor to use in confined spaces like 90 degree or something.
Nice one Allen, how times change the state of plumbing. I wonder, how many are still out there who can wipe lead pipe?
I might do a video on some old school stuff soon. Thanks for watching.
Can I buy only 1 pressfit gun with jaws either for copper and mlcp?
Hi Alan what Combi boiler would you recommend for a static caravan? Any ideas?
Something small and light, Maybe an ideal logic. Thanks.
I'm very keen to have a go with this mlcp pipe and pressing as it has its benefits especially when working on wet pipework and speed but my question is ,does it get damaged by vermin as with push fit plastic which I will not use.have you ever seen the pipe chewed
I have never seen one damaged but I guess it could happen. Thanks.
Seen copper that was chewed thru by rats they can chew thru just about anything thankfully not common. Mice common for plastic the new stuff barrier pipe supposed to stop them trouble is fittings ain't
Not cheap for the average diy’er, but very interesting tho, I’m looking at moving some radiator in my house, would this be a better option or stick to push fit for small jobs?
It's a hell of an investment for a few joints.
Where can i find these
It’s not really for DIY. Thanks.
please check uponor RTM & PUSH FIT
Thank you for the nice comments btw allen.
You are my pipework star.
Allen Hart 🤣😍
Are the fittings a lot more dearer than push fit and yorkshire fittings?
They are a little bit more than push fit but a lot better quality. Thanks
@@AllenHart999 Quality wins every time
I always go for quality, but I also want the customer to agree to a price, which is tough out here.
Like the idea of press fit. Only draw back I can see is your called to a job and don't hav correct Jaws etc. Think to many different types out there should hav been made to make them all one type
Say you were re piping a bungalow will all drops on show would you use press fit
Yes, I use it on all my jobs. Thanks
Good stuff for sure... Really sad that is only start to use in UK in last 5- 10 year... And still very very ignored by trade
What do you use? Thanks.
What’s the rough cost of these fittings
A bit more than push fit. Thanks.
Where is best place to get food deal to buy theses guns
No idea of any deals tbh. Thanks.
There's no tundish on the tprv....maybe the pipe size for the D1 should be 22mm.....that's about my level of knowledge for unvented 😂 oh yeah and its possibly overheated and then caused a leak at some point?
You watched to the end thank you. I will do a video soon and answer. Thanks.
My only guess with the BBU was that fluff and debris had choked the mesh filter. Unrelated but can't see the thermocouple capiliary tube on that BBU?
That areomatic burner never been strip clean in years to get in that state. Most off younger engineers won't even know to take end off and clean at service
2:20 of course you can
I reckon it is getting blocked because there isn't sufficient fall - the pipe is horizontal. Water is sitting in the pipe with bits of kitchen waste and these eventually congeal and block the flow. A poor installation.
Stephen K0nig Thank you for watching the full video👍 The outlet near the wall is higher than the trap, you are correct ❤️
