How to Join Plastic and Copper Pipes | Plumbing Guide for Beginners

[@gareth_gj]

Thanks for all the vids - have a couple of coffee's or beverage of your choice - much appreciated.

[@TheDIYGuy1]

Glad you like them. Thanks very much 😀

[@EasterlyWind]

My mate told me I was mad when I suggested to another friend in the room about the inserts for the plastic PEx pipe , so that it holds his shape during compression. Told me he never met a plumber that did it. Came on to youtube to find it and here you are doing exactly what I said lol. Knew I wasn't imagining things . Great clear video mate thanks

[@taga-bakilid3332]

I was thinking of this to connect PVC to copper pipes and now found you thanks

[@keefroberts1367]

I’m in the trade and I watched your vid on plumbing for beginners , and I’m really impressed. I know that the issues you covered are real issues for someone just starting out . So well done for taking your time explaining what’s what with pushfit and compression. Great vid .

[@TheDIYGuy1]

thanks for the support

[@batchrocketproject4720]

Really well explained, thanks. The first time I used push fittings as a diy plumber many years ago, the problem I had was that sometimes they're not fulling 'in' when they're 'in', it's almost a two-stage process - slide it in til it stops then push harder until it pops past the 'o' ring. Pointing out the pipe marks is excellent advice and would have set me straight back then. Keep up the good work!

[@TheDIYGuy1]

Thanks a lot. Glad you liked the tips and the video

[@paulg413]

Followed your instructions to the letter to replace a very poorly installed 22mm copper to 25mm MDPE (no reinforcer and using a 25mm to 25mm mMPDE coupler) with an all brass 25 to 22mm, perfect quick first time leak free fit, Much appreciated !👌

[@plumbbuild6517]

Thanks for the video just happened to run across it. Nice job I'm a plumber myself and I always use a bit of megaloc pipe dope on my compression sleeves just for the fact that , the squeek you hear when you turn the nut against the olive is the two metals starting to bind the megaloc works as a lubricant to keep it from seizing. But that is just alittle tip I've been doing for 30 plus years of plumbing. Thanks again for the videos I'll continue watching your videos and watch the older videos as well.

[@TheDIYGuy1]

Thanks for your comment and good little tip 👍

[@SpennieLence]

The solid inserts are for compression fittings on plastic but when you're using plastic fittings to plastic pipe you should be using the superseal inserts (STS15's).

[@thx5001]

I learned so much: inserts, plastic and copper pipe cutters, deburring, using the same branded items, no need for plumbers tape (which I usually always use). Top marks. Now to go shopping.

[@chrismoor1898]

As a long time DIY plumber (3 kitchens, 5 bathrooms and counting), for me, it's Speedfit all the way, the DIYers friend. I hate compression fittings, no such thing as a quick nipping up! Would never use them on plastic pipe, even with an insert, there too much give in the plastic for my liking. If I have to use them (radiators for example), I always stick some ptfe tape on them from the get go, saves having to dismantle it when it weeps! Good clear video on how to use them.

[@TheDIYGuy1]

Thanks. Glad you liked the video

[@matthew_baker79]

Nice video mate. As a DIYer I've used compression fittings with copper and plastic, but didn't know you could use push fittings. You've made my job of fitting a radiator tomorrow much easier Cheers!

[@TheDIYGuy1]

Glad to have helped you 😊

[@wonderworld4056]

Thankyou very much. I learnt a lot. Will be plumbing a new kitchen sink soon so your video on pipe connections was great.

[@TheDIYGuy1]

Glad it was helpful!

[@clarkgriswold-zr5sb]

Thanks!

[@chrismcandrew1041]

Brilliant! This inspires confidence. Well spoken, clear as crystal. Do I detect a Suffolk accent? 🙂

[@chrisnelson7500]

Thank you, my job this week will use plastic pipe for the 1st time, looks very straightforward as long as the prep is not skipped.

[@gerytremaine488]

Excellent video! You just saved me hundreds of dollars……. Replacing my bathroom and shower fixtures….appreciate your input. I’m going with the pcv off my 1/2 copper..👍👍👍

[@TheDIYGuy1]

Glad you found the video valuable

[@dontuno]

Many thanks for this video. I actually need to do just this to join a new installation to an old install, and this will save me hours of work. Off to Screwfix later this morning!

[@TheDIYGuy1]

You're welcome!

[@simonroberts9759]

Great, simple, straightforward video with clear explanation. Thanks.

[@TheDIYGuy1]

Your welcome 👍

[@billyblackie9417]

That is really great for a lot of garden enthusiasts as well as builders who are too embarrassed to ask about it great video thank you so much you are a real star

[@TheDIYGuy1]

Cheers 👍

[@randybeaumier]

I researched installing a chrome shut off valve on a pex pipe and was instructed to use a plastic insert on a 3/8” pipe but stainless steel on 1/2” and larger.

[@ceecampbell537]

Thanks!

[@TheDIYGuy1]

Welcome!

[@marekward6202]

Thanks

[@TheDIYGuy1]

Thanks so much 👍

[@Jailbreaker236]

Another great video your instructions couldn't be any more clear absolutely crystal clear..keep up your work mate

[@TheDIYGuy1]

Thanks, will do!

[@kerplunk1984]

I did my compression connections using your video, thank you very much for the help. Only thing, I didn't realise I shouldn't have used a super seal insert. I'll redo my connection with a plain plastic insert soon. Maybe you could add a point not to use super seal inserts with compression? Cheers

[@angelananka-bruce6240]

Awesome - just found you as I am about to attempt to renovate my bathroom - you sound like a local too ! (Norfolk ?) excellent tutorial thank you

[@bensteel3944]

You are a star mate in the way you explain things ... bloody awesome.

[@TheDIYGuy1]

thanks!

[@neilshearer7513]

Really clear video and exactly what I needed to know. Thanks very much, You've got a new subscriber.

[@TheDIYGuy1]

Thanks for the sub!

[@crazykittenvideos855]

Great video, I have never mixed copper and plastic but feel a lot happier about it now! Thanks, keep em coming

[@TheDIYGuy1]

Glad to help

[@johns9543]

great video & just what I needed as I'll be doing this Monday, thanks mate 👍

[@Chris-12423]

That very very reliable fitting started leaking 8 years later. Opened it up and copper corroded, turned green, and there are pits in the pipe under the space where the o-ring was. It's pretty obvious to me that sealing copper with rubber doesn't work, and I'm not sure why others think sealing a metal that corrodes with a rubber o-ring can last a long time. Sharkbite coats their o-rings with a grease, that should make them last much longer than these uncoated ones. I had two of them, one sprung the leak, second was full of green corrosion but had less pitting so it hadn't failed yet. And just for reference, this is city water, not even hard or anything like that.

[@don2deliver]

I prefer to sweat a brass pex adapter to the copper. Then use the stainless pex clamps. I figure it should last over 40 years before the Chinese brass corrodes. sharkbites leak when cocked the slightest bit.

[@SilverCymbal]

Very helpful video, I will never understand why compression fittings were so poorly adopted in the US. They are for sale here but seldom used, I see these working very well in the UK all the time too. Must be like your guys outlets 1000x better than our US ones.

[@Billy_Bull_Sheeter]

I invented plumbing. And i give my blessing to this video.

[@pieterjooste9686]

Dankie!

[@TheDIYGuy1]

Your welcome and thanks 😊

[@zdendaderman5253]

Best instructional video on the KZbin. 👍

[@allanryder679]

Great video thanks,just to make sure, would it be ok on hot water?cheers Al.

[@ginoasci]

the insert on the plastic side is to keep the plastic tube from collapsing. not collapsing in the totally breaking down sense, collapsing just in the slightly reduction of inside diameter sense. the copper can’t change its diameter size, but plastic is a lot more flexible given its structure, so the insert will help keep both inside and outside diameters in the same place so the “olive” as you call it, can do its job and stay tight around the pipe to prevent leaks. fyi, stainless steel pressure fittings hold up to 2000 psi, so if the copper fitting is rated to even half that at 1000psi, and the plastic pipe is rated to half of the copper at 500 psi, it’s well over the maximum pressure in any house hold all over the globe. un the united state the pressure doesn’t exceed 120 psi, so 500 psi, is well over the maximum pressure, that’s allows us to sleep good at night not worrying about any unexpected leaking.

[@RennieMalbrook]

Can you use this method on an abs pipe

[@ianwashington7910]

Thank you so much for this. Now I understand what the inserts are for.

[@TheDIYGuy1]

Glad it was helpful!

[@mykolasoloshenko8615]

Thanks for video. Helps to solve my issue. 👍

[@smurfsmurf2295]

By far the best diy tutorial on you tube

[@TheDIYGuy1]

Brilliant, thanks

[@rontorres4018]

Greetings from San Antonio Texas. Excellent. Your explanation is straight and to the point. You have really helped me move forward on my project.

[@TheDIYGuy1]

Thanks.glad it helped you out.

[@stuartshillito3406]

Great video, Ive never used plastic pipe and fittings for plumbing work before but I certainly will now, I always thought you shouldn't use under floorboards but after watching this video I am now confident there won't be any leaks, thank you

[@TheDIYGuy1]

Thanks 👍

[@jonathanrice-exec11]

That's all new builds use in the U.S. is PEX (PVC pipe)

[@Appemans]

Bedankt

[@CrIMiN8l]

Is it good to use these in central heating.? Thanks.. love the videos

[@marty3553]

I must say your videos are brilliant

[@TheDIYGuy1]

Glad you like them!

[@RoofRack2]

I've got that Bahco adjustable. Possibly the best tool I've ever owned. I take it everywhere. Nice vid.

[@TheDIYGuy1]

Thanks, it's a good adjustable

[@sandman7826]

Thanks very much for this vid, mate - you answered all the questions I had about connections just as I'm about to attempt the same behind what will become a tiled shower wall. Compression it is, cheers.

[@TheDIYGuy1]

Your welcome 👍

[@barryanthonywing4848]

Very informative,clear and a confidence booster to carry out the job in hand 🤜🤛👍

[@TheDIYGuy1]

Thanks 👍

[@kat0197]

If I don't know how to solder copper pipes can I use Fitting corners to join them?? Thanks for this video

[@sooh7068]

Watching this early just before I go into my practical exam, really helping me refresh my knowledge 👏👏👏

[@TheDIYGuy1]

All the best

[@sooh7068]

@TheDIYGuy1 thanks very much was appreciated went well and smashed it out the park 💪🏿💪🏿💪🏿

[@TheDIYGuy1]

Brilliant!!

[@paulmarshall6968]

Great video. Good pace, good audio, good quality

[@TheDIYGuy1]

Much appreciated!

[@Eddsparks74]

Excellent Video, very straightforward 🙂

[@biffoswilly]

JG peedfit always advocate using a silicone lube to prevent damaging the rubber o ring when making a joint, again check with the manufacturer to teach the proper jointing of pipes

[@Tom-mi4mi]

Good video but I am just wondering if the insert reduces the flow capacity of the plastic pipe as it is effectively reducing the pipe diameter. Thanks

[@robertpdxusa]

I don't want to sound like a back-seat-driver, which I am :), but in Japan they sell "connectors" with the copper side and plastic side tubing already attached on the other side. There is a flip side to this convenience, in Japan they sell almost nothing at a retail level so Amazon or other professional websites are the places to buy them from. There are also some threaded connectors if needed? Thank you for a perfect, short and truly informative clip showing your good heart willing to share real skills and tips:).

[@keithdearing2847]

Hi, as always I enjoy your videos, but I'm interested in which brand of plastic fittings you use and why. Cheers

[@alstud1]

Love these videos. As a remodel carpenter, we had to use licensed contractors for HVAC, electrical and plumbing. So I never picked up those skills. Fortunately you make videos that give me enough knowledge to make a project continue or to work on my own home. Thank you

[@TheDIYGuy1]

Glad you like my videos

[@SennaStar]

Brilliant video that any noob like myself could follow, subscribed

[@TheDIYGuy1]

Thanks for the sub 👍

[@martintehan1011]

Great video Thanks May I ask a question please about the pipe inserts .I notice they come in plastic,stainless steel and copper inserts .is there any advantage in using say a copper insert or do each type have a specific use .would be great to know thanks again

[@hankfoto]

Thanks, I new something was missing, and it was the insert for pex and plastic.

[@truthseeker7794]

I was an electrician/plumber for many years and retired about 15 years ago. I never liked the idea of plastic pipe and so never used it and I know very little about it. However, as it's more popular and more developed now I feel I may need to use it for a job I'm about to do at home. I need to strip all pipework from the kitchen wall so as to install Ikea units that don't have a service void, against the wall. My plan is to install one mains water pipe in the meter cupboard that also houses the mains feed/stopcock and it needs to be flexible. Any ideas my friend. Love your vids mate.

[@TheDIYGuy1]

Thanks 👍

[@curlydave6101]

Hi, just want your opinion on pro press connections & shark bite. Any info would be great. Great videos, very informative & very helpful.

[@truthpopup]

Another method I have used is to solder onto the copper pipe a brass fitting that has on the other end a barbed insert for a plastic pipe, to be secured with a crimp ring or clamp.

[@TheDIYGuy1]

👍

[@Humanity0101]

Really informative and concise demonstration. Successfully moved a radiator to the opposite wall. BIG thank you 👍🏼

[@TheDIYGuy1]

Your welcome 👍

[@paulburton210]

Ive been plumbing for 45 years everytime i make a compression fitting use jointing compound evertytime !!

[@gwynwilliams4222]

I had one yesterday and it was leaking I watched this video and guess what I tighted it the wrong way just gone back out and hopefully should be OK 👍 good video thanks

[@TheDIYGuy1]

Your welcome

[@frankjames4743]

Very nice instructional video. Thank you

[@andychapman5279]

Great Video just what i wanted to know. Now what about the grey plastic pipe ?

[@TheDIYGuy1]

I will see if I can make a vid on that

[@billymorton9595]

Thanks for this. Have failed so often soldering them. 😂😂

[@TheDIYGuy1]

Glad I could help

[@youssefbentachfin]

Thanks for the video it’s basic of plumbing who made you excellent plumber

[@casaMariaPT]

New watcher and subscriber. Thanks for this helpful video for us DIY'ers. Quick question if I may, I recently moved into a house that has existing PPR pipe, does this method work joining it to pushfit, or would you suggest using compression joints between them?

[@jollyolly58]

I might be old or missing something here, did you not use plumbers mate on compression fittings on olives when fitting an outside tap?

[@vipinpatel4545]

Well explained.Thank you

[@KdeB]

your vids are brilliant man, thank you

[@jsw060943]

Excellent video. Thank you for sharing. Best wishes

[@TheDIYGuy1]

Thanks a lot. Take care

[@in4dakill470]

Would it be ok for me to only use these JG pipes and fittings on flow and return pipes all the way to a radiator valve or would I need to use copper pipes to connect to the valves?

[@johndudash2579]

Very thorough exposA , appreciate the explanation, hope I can use info sometime, not yet though, thanks!

[@ronaldmelia1172]

I am not doubting what you have said. I have done it, but if i recall there was something to do with the oliv? use copper instead of brass or V Versa?

[@ianboyd9723]

If I am using a compression fitting to plastic pipe, I use a stainless insert, I also use a bit of sealant on the copper pipe.

[@metallitech]

Some good tips. I have a problem with compression fittings: doing them up causes rotation. This is especially a problem with pex, because it actually can rotate. My solution for now is to crush the olive, undo the nut to release the rotation, then crush it a bit more and tighten up. Perhaps I'm missing some other trick.

[@sivapillay8206]

Great advice Working to do as per instructions

[@b1h2u3p4]

Do you have to use inserts with hep fittings

[@stephenhaley2k3]

Great video 👍. One thing that would be great, if you've not already covered it, is it a bit of laymans breakdown of plastic Piping and the fittings. E.g this is pex but does that mean pex A or pex B? Do compression fittings work with both? And then there is PB Piping too...

[@TheDIYGuy1]

Thanks for you feedback 👍

[@Tonyv1951]

Excellent. Great communicator.

[@StephenEllerker-l6e]

Can you use both plastic pipe and fitting on central heating system

[@patrickmcgreevy3000]

Hi, can you use a isolating valves as I’m joining plastic and copper heating pipes so will be under ground

[@Wqk14xhddv7]

Thank You for this video . the Insert is the part I would use .. 👌 ...

[@TheDIYGuy1]

Perfect!

[@CarpeDiem601]

The “olive” is called a ferrule. Also I like to use a pipe insert with the ferrule. I have experienced crushing of the pipe and leaks without the insert. There is nothing wrong with the push fits in my opinion but the compression is certainly beefier.

[@marvinjordan9987]

Super informative video. Many thanks.

[@TheDIYGuy1]

Glad it was helpful!

[@mrobvious1100]

Thank you for taking the time to make the video I have one quick question is that just a standard half inch compression fitting and the package doesn't have anything on it that says metal to plastic or is that a specific compression fitting for different materials being joined

[@mrobvious1100]

​@@TheDIYGuy1 I guess what I'm asking is Is that the same fitting if you were doing copper to copper as you're doing copper to plastic

[@StephenEllerker-l6e]

Great video lots of interesting information thanks

[@paramotorpilot1749]

Thank you for the excellent video.

[@richardg476]

Would this be ok to use on a central heating system with all the pressures ?? (Not gas pipe)

[@267BISMARK]

Great video. Thank you very much.

[@TheDIYGuy1]

You are welcome!

[@dompatrinko8138]

Can i use this plastic pipe for my new radiators?

[@Russ1007]

Great video mate, very well explained and will surely come in handy for me in the future 👍

[@TheDIYGuy1]

Awesome thanks a lot 👍

[@jozefbelica1424]

Thank you mate, your video is better as AI bing 😂 and i going to do it as you explained. Thx again

[@michaelgrainger7421]

Sorry. Not sure if you're even answering questions but can I safely screw a compression fitting to a grohe rapido smartbox? It looks like it'd be ok. I'm having a go at a bathroom myself for the first time

[@mohamedyaseens377]

Very very useful video. Thank you so much for uploading this video. Really great video.
