HOW TO CHASE PIPES INTO A WALL – Plumbing Tips

HOW TO CHASE PIPES INTO A WALL – Plumbing Tips


– Plumberparts.co.uk,
honest reviews and advice. Boom! Holla! And welcome to today’s echoey Halloween Plumberparts video. Today we are looking into screening, I also have to sink pipes into a wall. Now, this was suggested to us
by a lovely man on Twitter, I think he was called “disco
dimmer” or something like that. His question’s appearing in
the screen below me right now. So, anyway, as you can see, we’ve got lovely chase here, it’s been chased down lovingly by Gavin. And if you look closely, we can see, the more you start, this is basically coming out with a grinder. And I’m sure all along, he wore gloves, and he wore goggles and mask. And basically, he’s ground it out, ground it out of there. And then used an SDS router or a chisel, to just gut all this all out, and then sweep all that away. We look at the floor, we can see that he’s made a lovely
little screen out just here. We get down, and have a quick look, we’re gonna see that
it’s quite deep screen. So we’ve got good sort
of, 40 or 50 mil there. And also, if you look here as well, we’ve got a pipe in here. You see, that’s nice
and deep there as well. We’ve got a hell of a lot of room. Before we continue,
you’ve probably realised there’s loads of
screaming kids here again. It’s just that sort of house. – [Woman] In, boys, in. In, in, in. – Basically (laughs) So the thing you’ve got to think about, that’s really important when it comes to sinking pipes into the wall, is obviously the depth of the wall itself, how you’re gonna fix the pipe, so when someone comes
over to render this wall, or plaster it or anything like that, that the pipes aren’t gonna move. And also, really, really, importantly, there how you’re going to try to insulate your copper pipe. Now, there’s kind of two
ways you can attack it. You can either insulate it
to stop the heat getting out, which is obviously a brilliant way, and also kills two birds with one stone. This is very important that the concrete, or any kind of render, doesn’t
touch the copper itself, ’cause it can rot through it. So, hopefully, depending
on the depth of the screen, we should be allowed to fit in this nice 15 mil by 30 mil wall. And it’s still got enough depth to then be able to render over that. Sometimes you’re trying to sink pipe into a single brace stop wall, which is only as much as
four inches deep sometimes. When that happens, you’re gonna want to dig out a pipe there, and then basically
gaffer tape up the pipe. We find that that helps to stop anything kind of climbing onto the
pipe when it’s drying out. Basically, what we’re gonna do is, I’ve got some double clips. We’re gonna pop a few
double clips in down here, get our pipes laid out in the bottom, and basically get our
pipes up in the thing, ready for Gavin to come over here in a few days’ time, to render up, and then we’ll be fitting
the radiator back on in a couple of weeks. We might do a follow up video for that, in our next Ask the Plumber, or whenever we come to do it. So if you guys subscribe,
then you’ll know that it’s been done perfectly well. So yeah, let’s do that now,
and I hope you enjoy it. And I hope the kids don’t
make too much noise. Speak to you soon, onsite! ♫ I’ve got some red
clips going, in this wall ♫ And I know it’s not funny, a bit (drilling) We’ll have just a quick look here, at the depth that we’ve got. See if we can give him enough clearance. I mean, that is lovely. So we can get a nice pipe round there, we’re gonna screen over the
top of that, absolute treat. (drilling) ♫ You’re simply the best, da, da, da ♫ Better than all the rest ‘Cause this is going up through the wall, and then out at the top, it’s gonna elbow sort of back over up in the loft space. Just gonna put the elbow there now. Pop that through on up. Ah, look at that. Huge amount of space, there, now. Brilliant. Well, it’s now just a matter of getting our lovely insulation on. So we’re gonna get a bit on like that, now where the clips are, we’re
not gonna put any on, okay? Because the width of the insulation, when there’s two next to
each other, is quite tight. Okay? So now we’re gonna do that. ♫ Ooh, you did me wrong (time-lapsed video) So, then, like I was saying, there are other ways. Okay, if you’ve got an issue with depth, okay, you haven’t got the room. Now, let’s say, the old
days what they used to do, is they’d actually get newspaper and wrap it around it. Anything to stop the concrete actually touching the pipe while it’s wet, okay? And also touching it later on as well, ’cause it does go through pipe. I’ve always found a really
good way to do that, is basically, gaffer tape. Gaffer tape is, you pop
it down here like so, wrap it around. Then you know now, that nothing’s gonna actually get on your pipe. And the same goes for the floor. Now, if I were to wrap as well, a couple of wraps around, and make sure there’s a
couple little ridges as well. So, it’s really sort of
free to move as it wants. And once that’s there, and all that, there’s no way that’s
ever gonna cling on there, or anything like that. There’s a nice little bit
of room in there, as well, it sort of protects the pipe a little bit, so that’s, I said, the other way. So, a closer look at that. You can now see that there’s
plenty of room as well, okay, and if we have a look down here, there is gonna be an issue, ’cause our pipes there
are sunk into the wall, nicely like that. I mean, as you can see, up here, we’ve got this gap
here, when we’ve got our gaffer tape on there. But when we go further up, you see there’s not as much of a gap. So sometimes, you do
have to think about that, obviously, though, it’s
much better to be able to insulate your pipes
properly, like this. So, once you’ve got this bit done here, we’ll just show you how you’ll basically splay that in the floor. It’s exactly the same, pretty much. I mean, sometimes, you’ve got to try and get a reasonable amount of depth of screen on top of there. But really, it’s what
you’ve got to play with, in the real world, that matters. You want to try and get,
really, 40 mil of screen out of the top of one of your pipes. But depending on how far you can dig down, obviously, that is really the main factor that will determine how deep
your screen trench can be. So, we’re gonna just basically, go our two levels out now, this is gonna be for 700 wide radiator, so we’re gonna measure
out 700 from our centres. And then we’re also gonna measure out, basically, I’d usually
leave it about an inch out, to then cater for your valves. Then later on, when he’s done
the floor screen and all that, basically, there should be a couple little offsets up into the rad, or maybe, if you’re really lucky, just
straight up into the radiator. But I’ve never won the lottery, and I don’t think Gavin has either, so we’ll see how that goes. You know, and I’ll supply the video in a few weeks’ time. So I guess I’m doing this now. Oh yeah! (time-lapsed video) So, there we go. We’ve got a lovely, lovely bit there. Plenty of room for Gav
here, to screen over this. Loads of room there, he’s
got about 30 or 40 mil on top of that. Got loads of room up here, going up into our loft,
ready to be connected up to our main heating system. And everything should
be absolutely amazing. I have enjoyed today’s
Plumberparts.co.uk video, I hope we’ve given you a bit more insight into how to sink pipes into a wall, make sure that they safely aren’t touched by any of the corrosive properties of the concrete or the screen. I have given you an idea, really, of how to do a little bit of pipe work, as well, in that stop-motion we did there. If you need any more
help, or any more advice, you can visit our website,
at plumberparts.co.uk. Obviously, you can follow us on Twitter, and Facebook, ’cause we
post loads of photos there, and all the best get used
in our “ask the plumber” videos that come out
pretty much in between each one of our instruction videos. Of course, it’s obvious, to subscribe to our videos, okay? So, I hope you enjoyed it, I hope you come back next time. I’m gonna get another cup of coffee, let this lot clear up. And then, I’m probably gonna go and try and book a round of golf tomorrow, ’cause the weather looks absolutely great. Also, I’ve got an
absolutely massive bucket of sweets as well, that I’m not gonna give to any kids who are trick or treating, I’m just gonna sit in front of the fire, and eat them with Big Jim. I’ll see you next week’s video, everyone, and remember, hold tight! Plumberparts.co.uk. Honest reviews and advice. (singing to himself)

Comments (100)

  1. Nice video mate, being a plumber/gas trainee, you've given me some great tips. Funnily enough I was doing this in my kitchen and 40mm down in the screened floor was the heating pipe, 10mm down more was my cold water main! What's the chances of that haha. Keep up the good work! Hold tight

  2. I see you use mapp gas for soldering, not propane. Is there a reason for that, or is it just what you had on hand?

  3. Smack bang in the center of the wall just were the home owner will hang a picture or two! Lol

  4. Like your vids mate but not sold on this one I'm afraid! You used to have to cover copper in walls due to lime in plaster which eats into copper, that is no longer the case. With the insulation the plaster is guaranteed to crack. better option in my opinion is to use plastic pipe, but either way spray with expanding foam then plaster on top a much firmer backing for plaster, prevents material getting to pipes and insulates

  5. One to watch with the sound off. I think the lad is in a lot of pain. 😉

  6. nice work it should be better if you chisel the wall on the left hand side better then the middle just in case if they want to hung something in the wall they hit your pipe  

  7. Nice pair of class 1 steps your using there , i have seen so many accidents with guys using a chair to stand on , it is utter stupidity and you as a pro should know better…..! 

  8. Just watched the vid and heard your comment about the sweets. " I'm going eat them all with Big G " – please don't eat Big G 🙁

  9. My friend, you are a good teacher.

  10. Geeza as always top vid would have looked amazing if pipes came out of the wall instead of the floor. Can you do a vid on under floor heating does and don't.

  11. The way I chase pipes into a wall is in the Carry on 'arse slap' style, then chase them round the room and into the wall. Works every single time.

  12. I love the videos to, but I thought that the Water Regs didn't allow pipework on external walls? Thoughts anyone? Keep up the good work!

  13. I just bought a Worcester 38cdi and I'm fitting it to my bungalow. Massive open loft and I'm laying all the radiator pipework down myself. Your videos have been very helpful mate 🙂 … (was all storage radiators, so its an easy, brand new fit)

  14. you're a riot mr Plumber! subscribed!

  15. Is that a rothenberger access chair ? Haha

  16. Haha, when I was an apprentice, my mentor threw me a lump hammer and a chisel to chase in the kitchen hot and cold on the fisrt fixes. I realised until months later he had an angle grinder and sds chisel in his van that he used when he had to do it.

  17. Can you chase plastic piping? If so, does it need protecting like the copper pipes?

  18. These vids are so good I might cancel my Netflix subscription

  19. wouldn't it be better to hang and position the radiator before soldering the vertical sections which go into the valves? How can you be sure that your short vertical pipes will go exactly into the radiator valves?

  20. Something you might have not known but "Duct trap" has metal in it which in the long run will cause electrolysis with the copper, Some inspectors in Canada wont pass.

  21. x factor materiel that is

  22. love the videos keep them coming

  23. Good vids . but getting more cheesey ever day ..
    and singings not good

  24. I want to put a picture up where those pipes are wheres my Drill

  25. i just had some plumbing work done . simpler to the video you just shared but i noticed that theres a considerable amount of heat coming thru the wall. is that normal

  26. So ar people paying for this kind of work in the UK?
    Im a plumber to, I mean, you are using copper, soldering it and works with a angle grinder.
    Here in The Netherlands we will work with alupex tube and a wall cutter, we can arrange this job within one hour without the use of a pipe bender and soldering materials. And you can chase alupex directly in the wall without any use off protection just plaster. So it will be much cheaper. Dont you guys use this in the UK? Please let me know.

  27. Nice video mate, how did use test the pipe work under the floor?

  28. You are loosing to the Handyman on subscription (though I subscribed with you) cos you is da man.
    Tip … get your voice volume sorted out (use a proper mick or MicK)
    Slow down on the big points cos most of us Brits are well you know
    Always show before and after pics

  29. Please be aware the correct method for wrapping pipes in screeds and plastered walls is to wrap them in Denzo tape when advising other non plumbing professionals , as the content of either gypsum or cement will corrode any copper pipe work .please note I am a plumbing lecturer and have been a gas engineer for over 30 years.

  30. hi, i want to have wall mounted showers in my bathroom, the wall is a cavity wall and its the supporting wall. is it possible to trace pipe work on such wall or i have to build false wall? thanks

  31. Outside Wall You Must Have Mild Winters. This Would Be A Freezing Problem In Northern Climates Even With Glycol. Nice Work!

  32. Any particular reason you are using copper rather than plastic?

  33. Can you please make video on how to pressure test pipes with standard air pump. Many thanks

  34. is expanding foam ok to use touching the copper pipe?

  35. Is it the same principle when using plastic push fit pipes? Does it still need protection from the screed and plaster?
    Just subbed. Great Chanel. Thanks

  36. One serious Nutter, but a funny ONE!  oh Yeah

  37. building reg…Vertical chases should be no deeper than one third of the wall thickness!

  38. For my shower, I have concealed pipes into a solid wall. My builder didn't do a good job which made the tiles crack and pop out of the wall. Now having to do it again! The pipe is plastic coming from floor to the control valve. Then copper pipe from control valve to shower head. Does it only need insulation on copper pipe and also the plastic?

  39. Red rawel plugs are for sparkies!!

  40. WHY DIDN't you test for any leaks before covering with foam insulation. How would that be done. thanks

  41. Hey jolly fellow…Do you have any videos on how to remove galvanized pipes from walls and replace with PEX ?

  42. Don't intend to sound like a smart arse here but those look like they could well be vinyl asbestos floor tiles that have been mullered by a breaker. Take care guys 🙂

  43. 44 thumbs down are from sparkies😜

  44. Do you just fill the wall now with some 'cement' type substance or would you pre-fill some of it with that foamy stuff first?
    It must be a hell of a job to fill in, and then plaster?

  45. hi, im currently renovating my house, im going to fit a combi in the loft and re pipe the house, i noticed my friends new build is piped in 10mm plastic is this ok or should i use 15mm plastic, im going to chase it in the wall also, its a 4 bed house and its in microbore at the minute, love your how to's they are very helpful. thanks

  46. nice neat work good job
    journeyman plumber here
    i know everyone would have their own ways of doing it especially my boss lol..

  47. a ghost at 5:20 …… i guess ghosts wanna learn plumbing also.

  48. Quick question about insulation, why 15/13 and not 15/9? it's more compact, does the same thing and it's cheaper:)

  49. Wall trench, haha. Too many chases like this and your house will collapse.

  50. you ever use "sharkbite" adaptors? just wondering as saw them on an ottawa plumbing channel and they looked really good especially if one is wanting to DIY and has no prior knowledge or experience of soldering, also makes it possibly easier as can go from copper to flexi when installing a bath! which is what I want to do with our shower only bathroom. I am just thinking about it. might just get an actual professional plumber in once Ive got the easy bit done (installing the actual tub) lol!

  51. we moved in to a grade 2 listed building in 2010 which had the bathroom newly tiled, some of the tiles fell off in 2016 which still hasnt been fixed and was just concerned about presensce of asbestos as we have 2 children? should I be concerned and should I call in a surveyor? its a rented detached house and I dont want to piss off the gentry whom we rent it from as Ive already asked if its alright to install a bath in the shower only bathroom!

  53. Nice video, but you used copper which will simply corrode and get pin hole leaks. How fast this happens depends on the kind of water. Could be 25 to 30 years. Could be 15. Might even be 40. It also depends on how thick the copper is and the Ph or how acid the water source is. Ask me how I know.. Now faced with a nightmare situation 20 years after home built, pin hole leaks are sprouted everywhere. The fix was supposed to be a water softer and a tank, but had that been done, it's annoying to keep it going, to keep adding chemicals and that costs money and it would break down too. Also we were not even warned we needed this with our water. So it started with sharkbites, but now more and more elbows are going. It will not get copper, but likely get PVC. Also the person who put the well pump in used pvc, and the other plumber used copper. Guess which pipes have no deterioration after 30 years on a 1987 home? Yep, all the pvc used from the well plumbing looks the same. I broke a pipe by having something heavy smash it. It was one repair. The inside of the pvc looked like new. All copper pipes are so thin they are like coke cans you can almost crumple with your fingers. As for insulation, that's nice, but the amount of loss in energy is negligible, and say it's 20 years from now, and they started leaking. Someone will have a nightmare on their hands. Thankfully it's not a larger home. As for what I drink both pipes are both supposedly ok (unless copper leeches out lead?), but I've always used a filter even though we have good tested water. The other thing is moldy dry wall isn't healthy either, and now that has to be changed… and it all could have been avoided by not using copper. Not trying to mess up your nice video, but I really have to wonder about copper, especially in certain places, if not all. Have to replace two ceilings now and a bit of carpeting too. You did a great job, it's just that it's that copper…

  54. Just reading the comments, and geez so many Chiefs and not enough Indians, great job and chair was handy so why get steps, and in 30 or 40 years the radiator could have been moved numerous times, so stop all the bitchen, always someone who knows better, once again great job. oh one last thing, wanna join my band lol

  55. Loving your plumbing videos! I could almost contemplate chasing my own pipes in.. however they do at least give me an idea of how the work should be done (insulated etc). Am now looking for a local plumber to do the work. If I was tackling exactly the same task as in this video (including the chasing out, pipe laying, insulation and radiator installation (already purchased) – could anyone give me an estimate of a 'reasonable quote'?

  56. hair felt lagging saves the deep chases!

  57. Do you recommend insulating cold water pipes to protect pipe from concrete?

  58. Can you not use a roll of plastic save on potential joints /leaks ?? Would it be OK with render ??

  59. Ps loving the videos mate , keep up the good work 😁

  60. Is it asbestos floor tiles?? Shit!!

  61. So do you have 100% guaranty you will not have a leak and having to take the insulation to mend the leak?? Test first and then insulate and tape pipes??!!

  62. Kind of cowboy job that lololi

  63. Can't run plumbing in outside walls in Canada so I don't need to worry about ever doing this

  64. Got my NVQ level 2 in plumbing but it was a full time course of 2 days!!.. completed it in 2 years at age of 18 but couldn't get apprenticeship to do NVQ level 3. Now 15 years later want to get back into it. But will need to start from scratch probably do a refresher course too. Top video

  65. Fellas !

    Word of warning using todays tools prop & map bottles when detatching.

    WEAR GLOVES AND DETACH IT OUTSIDE !

    I had a bottle empty its contents when it appeared no gas was coming out , ultimately the pintle inside failed and freezer burned my fingers and hand quite bad.

    Cheers
    Dave

  66. I love this video, in the USA here. I have a few plumbing vids myself you might find interesting, check one out at https://youtu.be/R5lfB2G8fnQ

  67. So this tape you stick on, would it’s condition change due to the pipes getting hot, and how long can it last with the pipes?

  68. When chasing pipes in, are new pipes required or can existing pipes be used? Also what about when re-plastering the room anyway? Looking at purchasing a property with back boiler and pipes on show so trying to figure out how much needs spending!

  69. Help! I bought 2 flexible pipes that have that skinny m10 end for kitchen taps but my taps are a bigger(maybe 1/2") male end not female. Can I buy something to adapt them?? I need it to look like the wider female bit at both ends. I would just buy one but mine are 120 long and can't find something that long in wickes

  70. Do plumber have piping routes like sparks have cable routes, so to avoid drilling or cutting into the walls where there’s pipework ???

  71. At these work speeds It takes months to install a few radiators

  72. Hi mate, great vid. Quick question, I have chased two pipes in the wall like this, but not as deep, chased about 20mm depth out and about 40-50 mm wide and installed 10mm pipe. Can I clip them and tape them with gaffa like in this vid and just plaster over or should spray small amount of foam over pipes before plaster..
    Thanks

  73. I'm in the north east uk. Need rad pipes hidden in 3 rooms. How much should I expect to pay a plumber to do this?

  74. When so much of structure is cut doesn't it make the walls weak? I ask because plaster is only 10mm so you must be cutting brick/block.

  75. Do solvent weld wastepipes need sleeving/protecting when burying in screed?

  76. Howdy, I was wondering what your opinion was on having exposed copper pipes in the bathroom. I want to do up my bathroom, take out the bath tub and put in a walk in shower. But I don't want the to break or chisel down the wall just to hide pipes, I just don't want them to damage the brick or concrete or destroy the wall. So I was thinking of just extending the pipes from the bathtub which is removed, having exposed copper pipes and just putting shower and tap fittings. I heard that lather can be applied in order to keep the copper pipes looking great. I am not sure if they make plastic coverings that clip on like the ones they make for electrical cables to hides tv cords , so you don't have to chisel down the wall. What's your opinion?

  77. you are so fricking annoying, couldn't bear to watch your otherwise useful video :[

  78. Cool video as usual , but tell for copper pipes in concrete they to use a sticky tape call demzo or is that a thing of past or am showing my age and also in US they just put plastic sleeve on top of copper pipes is that something we can do in UK?

  79. Please be carefully those old vinyl type tiles can contain asbestos ,so not a good idea breaking them up

  80. I'm not a plumber and just bonded straight over the bare pipes coz I'm a fuckin gangster. 12 years later still going strong

  81. 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

  82. Why cant we have the pipes outside n have it boxed? Lets say At one point pipes might expand crack n start leaking or joints give way. Then It will be a costly job. I am not an expert but i have to replace my boiler n the engineer told me there is a chance of pipe leaks since they are old n the new boiler preasure might expand the pipes n make them leak. To do pipe work for 3 rdiotors £1200. Now im worried bout changing the boiler. Cost is £3700. In case an other £1200. Breaking my head.

  83. I made it about three weeks ago. On stodoys I learned a lot about it. Check it mates.

  84. About to renovate shower room. Need to bury hot/cold feeds. Probably gonna use the gaffer tape trick then use some bonding to cover before tiling over. Wish me luck!

  85. Would the plasterers bonding take to the insulation I alway use gaffer tape or if it’s a Friday FUCK ALL HAHA

  86. Hi mate Can u please tell where or how I can get a 6mm bore flexi tap tails

  87. What the hell is all the yelling trafficking kids

  88. Hi mate great video I'm.not a plumber can you shed some light and what I'd be looking at if I done the chasing (firmer brickie who does odd jobs ) for 2 rad pipes 2 water supply pipes for sink and if allowed a gas pipe to be put into a recess for a clean finish ? Thanks

  89. Was there a reason for not chasing the horizontal runs of pipes into the wall?

  90. How did your mate chase that out so neat?

  91. Bloody hell .. skill levels dropping to all time low .. sad thing is, those with less knowledge than yours think you know what your doing… YouTube is a dangerous place.
    I am not here to slate but to ask you to check facts before releasing videos.

  92. Would you worry as much about the screed eating the pipe if you used plastic pipe in the wall cavity? Also would you still need to insulate the pipe if it's barrier pipe??

  93. Very informative videos. Need a little help if possible. I am currently in the process of doing my kitchen. The cold water feed is in this room so will supply everything then go upstairs and hot water will come from upstairs down to for sink ect. I planned to do exactly as you have and chase the wall out for the pipes. I was going to use 15mm copper can I use the exact same method as you have using insulation ect or does it need to be done different as it is hot and cold water? Thank you

  94. great video i am just doing this exact job in our living room. many thanks for the tips. and video great slo mo for those not experienced keep it up.

  95. Great vid, terrible signing! Less tricky if you apply the duct tape before offering the pipes up to the wall though. My need for watching the vid was to see how you finish the holes from the floor to the rad,

  96. That doesn't look all that complicated.
