DRILLING HOLES IN JOISTS & WOOD FOR PLUMBING - Plumbing Tips
HTML-код
- Опубликовано: 9 дек 2016
- Drilling holes in joists for plumbing and pipes is easy and we show you how in this video. There are regulations in the UK you must follow in new build installs. However on older buildings that is impossible. We show you how to measure out, what tools you need to drill the holes, and how large to drill them.

So you can drill a 50mm hole in the centre line of a 200mm joist then mate? Thanks
Awesome. Video and a good refresher for a job I’m doing tomorrow.
Well done, great walk through the whole process - important reminders of the technical details.
Cheers mate!
Great video, and great talk through thank you!! Brilliant.
I still can't understand why some knobheads give a thumbs down for any of this guys videos? Been watching these for the last few years through my apprenticeship & he's rad, in all of them. Good to see the video editing has come on a long way since the start too. Always a thumbs up here.
Cheers mate....they're all tossers!
Me too mate.. he's my new guru!
You are officially our favorite plumber on YT!
Ha! Cheers guys! SUBSCRIBE! ➡️👉 ruclips.net/user/plumberparts 👈⬅️if you haven't already!
love the way you explain mate!
Cheers dude! SUBSCRIBE! ➡️👉 ruclips.net/user/plumberparts 👈⬅️ IF YOU HAVEN'T ALREADY! 😎
We’ve studied this today in the College . Great vid bruh 😁
Hi when working out the position for drilling due u use the to also length of joist or just to where it reaches a supporting wall thanx
Fantastic video, very thorough, full of information and still very enjoyable!! Thanks, looking forward to the rest of the installation
No worries dude!
That drill is a beast I always use my battery combi drill thinking I am saving time not dragging transformer and extension about but watching that I don’t think I am
Worth noting that an impact driver will take those spade / flat / auger bit drill bits (1/4" hex), combined they will fit between joists up to 300 centres 😊. So long as they're decent bits, you should fly through just as easily with an impact. (Thought I'd mention incase the site may not have electricity etc)
Hi would i run hot supply and cold return for each floor of a house or just one run and tee of 22 into 15 for the rads. Thanks
Great video as usual. We're starting first fix of our new home conversion (from old offices) - loads of really old joists that need reinforcing because of decades of crap plumbers, electricians, BT engineers, etc...
I use an Erbauer angled chuck (£16 from screwfix) instead of a special angle drill - does the job just as nicely...
Top man! Good luck with the conversion!
What are the regs for putting holes in I joists / engineered joists, wanting to run waste from a shower through 4 of them. Thanks
Wow thats quite the drill
Just studied this for my plumbing processes test ! JAMES IS ABSOLUTE QUALITY !
No worries MAtty!
Does this apply to plastic pipe? My garage pipes (below the bathroom) are a mess all over the place 70s build. I'm using 15mm plastic pipe to T into the flow and return to a new radiator. I decided on plastic for the slight flex as were the pipes come up through the floor is very tight. I'm confused though, how far down the joist can I drill?
Just stumbled across your channel....how cool!! LOL! love the work. Love the attitude. Brilliant channel :-) Me thinks I can actually learn a lot here. Oh and just subbed too :-)
Top stuff! Thanks!
you Shona be a teacher 🙏 boss
Any tips on getting pipeholes cut through floor for radiator on point everytime
I’m fitting 4x4 joists, can I bore a hole through them??
Haha this drill music is epic 😂😂😂
Quite why using a power tool and rock music go so well together will forever remain one of the mysteries of the universe. But it is an undeniable truth.
Hi hope you can help. When running plastic pipe for plumbing will I need separate got feed for upstairs and downstairs reds. Also am I correct in assuming that once I drill say a 25 mil hole the next one has to be 75 mill apart. Thanks
My layman's understanding is that for new installations upstairs and downstairs have to be separate heating zones controlled by their own motorized valves or some other technical solution. Not sure how this would be possible without separate pipe runs. Hope that helps your project four years ago!
When measuring out the joists, did you measure and mark EACH joist, or just measure the first and last one then twang a chalked string line along instead...??
Measure and mark each!
Hi when running first fix plumbing for rads would u reccommend main feed if 22mm then tee off to 15 for rads feed and return thanx
That's exactly the theory to follow mate gives loads of circulation .I always go as far as I can with 22 mm pipe and you can branch off to your last two rads on the line using a 22 x 15 x 15 mm tee .sorry saw your comment and noticed it wasn't answered yet .I'm sure plumbing parts will agree anyway 👍
Best song yet James |,,| Who the flux is that on guitar?
Holes drilled in joists are also supposed to be 3x hole diameter apart from the next adjacent hole. So the holes drilled at 10:04 are not to regulations. Not trying to be picky, just trying to help people out who are using this video as a guide. :)
Yes, but at 19mm I had to keep them in the 25%-40% range. I'll let you know if the house falls down!
So the question is if you have no choice do you drill the holes closer than you should or go outside the 25 -40% zone? Either way it isn't that critical provided the joists are not over-spanned but as you said this is about getting it past Building Control. If in doubt give them a ring.

I have some holes to drill. Everything is ready........ However, does anyone know who did this epic music?
I thought holes couldn't be less than 3 times the diameter of each other? starting from its center. I am confused can I have 4 holes so close to each other? Thank you!
How far should u keep a cold pipe from a rad pipe/boiler pipe
What was the make of the excellent shower head you showed here, I forgot to save the video
What size holes did you drill for the 22 mm and 15 mm pipes? Your videos are always really helpful.
32mm for 22, and 22 for 15, SUBSCRIBE! ➡️👉 ruclips.net/user/plumberparts 👈⬅️if you haven't already!
Hey Plumberparts, Would you use those sizes for masonry?
did you ever do a follow up to this mate. As a trainee desperate to learn as much as possible these videos look awesome
sammypfc1 hello mate. Filming it next week!
@@plumberparts Got a link?
If you don't understand the reason for the regs, ask your local controllers for pictures of joists that collapsed due to service holes drilled in stupid places... was a bit of an eye-opener for me.
Good point!
The funny thing about regs is where and when you have to practice them. In Colorado in the 70's and 80's, you couldn't go *beyond* 2 x depth of the joist, unless it was a laminated joist. So where he was drilling would be a clear violation. Back in another time, and in another place, that is. :)
BTW, I still have my HoleHawg. Now that's a serious drill motor...
Are you saying that you have to drill all your holes between .25 and .4 of a span and all notches between .07 and .25 of a span? How about when you have pre-made trusses? Really helpful and I learned much. Also, jealous of your tool belt. My brother stole mine. No Christmas gifts for him.
U should insulate the pipework where there are conflicting runs with the cables to prevent any direct contact and to avoid premature deterioration of the insulation.
Next video mate!
I knew u had this bro!
Love the vids too by the way!!
Cheers!
Nice.....did you ever do a follow up video pulling the pipes through? Cheers.
Still not filmed...but in the 'pipeline' HA!
Where I can I buy this drill from ?
James. I find it much easier to use a auger bit in the angle drill. The drill has a low rpm it's the perfect set up👌
Cool beans!
you know it!
At 4:00 when you say that you need to be between 25% and 40% of the span, does that mean from end to end?
Yes mate. SUBSCRIBE! ➡️👉 ruclips.net/user/plumberparts 👈⬅️ IF YOU HAVEN'T ALREADY! 😎

I'd like to know the wisdom behind the 0.25 to 0.4 joist rule. If you drill on the neutral axis of the beam, you can drill anywhere along the length imo. By drilling holes close together you're creating a slot nearly, which would weaken the beam.
Building Regs
Shouldn't there be a 2 inch gap between holes?
when drilling the holes in the joist do you need to drill them three times the max diameter apart or is it just 3 times the diameter apart of the hole size being drilled?
There's no specific calculation, as sometimes it's a funny material, or pipe size. I always allow minimum of 2mm clearance each side. So for 22mm pipe, I'll drill a 28mm hole. Hope that helps dude!
My question was more aimed at the spacing between the holes in the joist as from what I have read, building regs states you need 3 times the holes diameter spacing between each hole drilled. But some state it is 3 times of the max size hole that can be drilled in the joist whereas others just state 3 times the hole size being drilled (so for a 22mm hole it has to be spaced on centre at 66mm). However, if it is spaced on the max size then it does not matter what hole you drill you still need to space it like it is the max hole size being drilled so say for a 150mm deep joist has a max of 38mm hole so 114mm on centre spacing (even if you are only drilling a 15mm hole). Do you know what is the defacto rule to follow around this?
Hole's must be 3x their actual diameter apart ( that's from edge to edge, not center to center i believe) and must be at least 100mm away from any notch. Hope that helps Mark
What is that wooden building you are standing in. Is that a wooden extension on the side of a house? What do you think of auger bits?
Love Auger bits too!
The hot the cold, the hot the cold. The flow and return, the flow and return!

drilling is necessary to install modern plbg. to customer demands
Get a laser, set it up on the floor. Hit all the joist and measure up. Boom perfect run.
Nice! SUBSCRIBE! ➡️👉 ruclips.net/user/plumberparts 👈⬅️if you haven't already!
Would you not go bigger with the holes so the pipe insulation will go around the pipe and through the hole too? Might help stop pipe bang on the joists in the future, once the joist is big enough. Nice to see you measured it all out, I'd have probably used a snap line to mark it out.
You can only go with the regs, bigger holes might contravine the safety regs of the timber!
How did ŷou pull through long lengths of 22mm pipe through when the joists are so close together?
Wait and see in the next video! SUBSCRIBE! ➡️👉 ruclips.net/user/plumberparts 👈⬅️ IF YOU HAVEN'T ALREADY! 😎
Already a subscriber, but couldn't find the sequel video...
Got that song for sale yet? Drilling holes yeah drilling holes
At 4 minutes into the video, you have a diagram showing where you can and can't cut into the joists. Where did that come from?
7:27 - Is it okay to run hot water pipe so close to wires?
Love the singing BTW
ArcanePath360 You don't always have a choice
i know its 25mm for a gas pipe ...dunno what the regs are for hot water
Pp. Your drill? Is it a cote drill with an angle atachment?
#core
Is an album on the way? 🎸
Is it better to run copper or flexi pipe?
Flexi in the floor! Less joints! SUBSCRIBE! ➡️👉 ruclips.net/user/plumberparts 👈⬅️ IF YOU HAVEN'T ALREADY! 😎

is that a makita angle drill?
Yep!
plumberparts absolute beast haha
Where is the follow on vid from this please?
Brrrrrrrr big up
haha that song is nuts. Is that your own creation?
The 'vocals' where!
Lol 😃😄😆😀those guitars
did you get the hat for xmas?
Guitarist sounds like Steve Vai, or am I imagining that?
I don't think he/his record company are copyright strikers.
First, let me say that in reality it's fine and not going to be weakened in a way that matters.
BUT I don't think you've entirely followed the code:
1) Drilling through the linked joists was off centre, code says to go through the neutral axis
2) the group of 4 holes, code says the the minimum spacing is 3x the diameter centre to centre. Looked closer than that to me
Top tip - make your holes and place your pipe before the electrician! They tend to not worry about the plumbers pipes which have to go where they go..
Electrians may also take the holes you drilled
Why use the term 44mm then say 7 inch joist?
7" joists are tiny. also those spade bits suck. my hole saw will snap them like toothpicks.
The less fittings the better the flow FYI.
Mmmm I thought it was 0.25 xt the span length and 0.4 x the span length to get your drill area on joist …
That's what he did. 👍
Here in the USA, the holes drilled in those joists are illegal. You can only drill holes within the center third of the joist span. Further, the O.D. of the hole cannot be within 2" (5cm) of either the top or bottom edge of the joist. If the depth of the joist is D (with a 2" x 10", D= 10" (9-1/4" actual)), the maximum size of the hole is D/3. So, for the 2 x 10 joist, the maximum hole size is 3-1/8". As well, the spacing of the holes within the center third of the joist have to be no less than D (9-1/4" center to center). Hope this helps.
You sure that's not backwards? The centre third is where most of the stress is, so it makes no sense to encourage people to drill right there. In Ontario, we only allow notching on the top of the 1/3 span next to the supports, meaning the middle 1/3 is banned. We allow boring anywhere along the joist, so long as it's 2" from top/bottom/another hole, and doesn't exceed 1/3 the joist depth. City of Markham even shows a hole right next to the wall in its official doc: www.markham.ca/wps/wcm/connect/markham/ba6700b3-30a6-4d94-9ff2-be2a5891b897/Notching+and+drilling+of+framing+members.pdf?MOD=AJPERES&CONVERT_TO=url&CACHEID=ROOTWORKSPACE.Z18_2QD4H901OGV160QC8BLCRJ1001-ba6700b3-30a6-4d94-9ff2-be2a5891b897-msjFK1M
We're in the UK though, US regs don't mean anything here.
Being 0.25 of the span from the wall before you can bore seems very restrictive. Here in Ontario we have limits on where you can notch (not allowed in middle 3rd), but you can bore holes anywhere along the joist so long as it's further than 2" from the top or bottom of the joist. Even right next to the wall, the centre depth of the joist has negligible stress on it.
Never use gloves when using rotation tools, one grab on the glove and it ripped your hand off.
Nah. Glove rips.. Happens to me all the time.
@@jacksonpuckett6115 you are tan very lucky, better use something like nitrile gloves, they will ripped if catched.
Better than your fingers.
@@WaschyNumber1 That's what I'm speaking of, nitrile gloves.
Larger hole will affect the structure more than smaller holes. thats common sense.
Yep!
more of a head bag than a hat :)
Had it years though!

hello,i am plumbers,what to do to work in UK, are looking plumbers?
dan dan not if you can't speak English
Wang? 🤣
love your videos.. but i aint sitting through a 2:42 advert.
As usual- the selfish electrician has run his cables in the middle of the neutral zone without a thought for anyone else...😡
I'll tell him that!
Im not a plumber but those electrics are not really video worthy...
Congratulations....you wasted 12 minutes of my life
Quicker than my wife then!
2:52 of blabbering and advertisement before you even start on the substance of the video. Seriously! You have to catch and keep people from the start with the actual reason and substance for the video or like you see no one will watch and everyone will give you thumbs down! Pretty simple
