How To Drill Holes Through Floor Joists

[@usmcfrommt9790]

I’m doing a remodel on a 1904 home. Your videos have come in perfect time. New subscriber!

[@garyknight6766]

Nice job. I am a retired structural engineer and you did a great job on this. Like to see you snake the pipe through the holes.

[@hdiaS4]

Exactly, how the a single piece of pipe went in, is the big question. Please post that, great job.

[@SteveAddis]

Yes. Would it be safe to say he used well placed couplings? Or removed some of the joists at the far end to get some clearance to the level of the sister joists. - Great job.

[@iambyrdman]

2:16 What a blessing, bringing smiles to the world Thanks for all you precious time!!!

[@Thedeadbird8]

Appreciate the thorough instruction and explanation. You have a beautiful family, thank you for sharing.

[@christopherzimmer]

This is so great, Ben- thank you. Especially helpful was your explanation of the strength properties of the joist, and your illustration of the slope drop. If the opportunity presents, a similar video, but for vertical studs, would be so great!

[@Sparkeycarp]

Your storyboard was a great tool to explain this.

[@randywebb1501]

Please post the rest of the bathroom install when you finish. Very helpful to me. Thanks.

You're a blessed man, Ben ...without a family... a man has nothing

[@BenjaminSahlstrom]

Couldn't agree more!

great video bro. Super thorough. You're an all-star.

[@bgable7707]

Well done, a recent hard freeze caused some pipes to freeze inside on an exterior wall. I was reading up on the code for the city and your description was spot on. I REALLY like the analogy of a joist being like a truss and how the mid section can be open do to the push/pull effect of a truss.

How precious...you remind me of my dad when he remodel our house. Watching him build that house instilled confidence, respect for engineering, desire to improve and a constructive can do attitude. They will look back in their files and they'll appreciate the hard work and love that you have shown them. I remember being that little doing the same thing. They are very blessed😁

Fantastic! Thanks and love the crew!

[@TheSlipperyNoodle]

Great video sir.

[@mangravy2000]

Great information!!! I wish I had known before I did my runs. I used a 2 beam laser with marking guide template, it made the holes dead balls in perfect alignment and the copper pipe slid down the 30 foot run with zero issues.

[@kamalimal3627]

This is great info. Thanks

[@User-pb8pd]

The video was very good. Using wood was right for this application, but those working with longer spans you might look into using LVL.

[@openeyes-411]

Good stuff Ben!👍 About the only thing you didn't touch on is the relationship of the size of joist you're working with compared to the span - which in your case of a 2x8 over what looks to be only a 6' span leaves you more than enough structural integrity even if you did run a little over on the drainage hole minimum.😉

[@lancemcque1459]

[@Ojeramup12]

Very informative, thanks

[@barrymilam9665]

You could use inch and a half pipe for the lav. and shower or tub so you wouldn't be cutting so much wood. If you need to cut more wood out you can put in a flitch plate in and have holes in it, plus you would need some bolts through the plate and floor joists. It does take more time and money, but sometimes you have no choice to pass your inspection. You did a good job explaining where you can or can not cut holes in joists. I know a lot about this cause I've been a plumber for 48 years and 95% of my work is remodeling in old homes.

[@BenjaminSahlstrom]

I would have used 1 1/2" but since I am doing a horizontal wet vent the minimum size is 2" here in MN. Our plumbing code is based on the UPC now so is similar to quite a few other states. Thanks for sharing your experience!

[@barrymilam9665]

@@BenjaminSahlstrom If they require it, do it that way. Here in Alabama we can use inch and half on a wet vent. We are using the international code down here and we are still using the 2015 code book......

[@barrymilam9665]

@@BenjaminSahlstrom I myself use 2 inch, but it's legal if you decide to use inch and a half. I would only use it if I were about to compromise the structure. Also if you were taking a state test you have to use the smaller size in order to pass the state plumbing test....

[@123mjolie]

Great Job Dad !!!

[@klostdad]

Great video Benjamin! How about wall studs for a future video?

[@BenjaminSahlstrom]

Yeah I think I'll work towards that! Thanks for the suggestion.

[@hoxymoron]

This is helpful. Do the same rules apply when you have two sister joists? Can you drill through both of them using the rules you’ve outlined here?

[@jacobecorder]

Great kids man. Great info also. Thanks

[@jabomiles6947]

[@MrTooTechnical]

Great vid. Hear are some tips: 1. Make sure you add clean outs under the sink. 2. Make sure to buy a one piece toilet (Costco has a great one). 3. Make sure to add redguard under the toilet area so incase the toilet ever leaks the floor won’t rot. 4. Make sure u add hurricane ties to the roof rafters since they are exposed. 5. Make sure u stub copper thru the walls for all shut off valves but u can use pex for the water supply.

[@b.j.nelson155]

Too bad I didn't watch this video before installing that wire yesterday!!! Then I wouldn't have drilled a hole too close to the top edge of my 2x8 floor joist. Thanks for the tip on the nail protection plate...I used that to protect my ignorance...and electrical wires!

[@lningzhang6655]

Knowledgeable, renovating my kitchen, plan to run a 3" drain pipe through 5 joists of 8", the holes that run the drain pipe are over 3" Dia, so I want to use the metal joist reinforcement plate to support the joists. it is possible? Thanks.

[@robertsteich7362]

I remember watching a video, it could’ve been This Old House, or even Mike Holmes. Where they drilled a two certain size holes in the corner of the notch first. Then sawed from the edge to each of the “corners” then across to each of the “corners”. This was to lessen the stress of the wood splitting away. If you need a 3” wide notch. Drill two holes 3” away from each other at the depth you need. The hole size should be 3/4” (guessing here). Then cut away the wood to the holes from the edge and then to each other. While maintaining the circular pattern of the “corners”.

[@edward-x3s6f]

Ben this video reminded me of Bob Villa 😉

[@dperson6557]

Placement of toliet flange... not sure but I believe u need 15" all direction from finish walls and cabinets... also was woundering where bringing in water from. I've seen pipes in outer walls but would avoid that.... You appear to be in attic what do you plan to do insulate supply lines. long forward to more videos.

[@realdeal8078]

Hi Ben.. Great video.. How did you get into the trades? Did you have family that got into it?

[@JW77]

such a beautiful family

[@BenjaminSahlstrom]

Thanks! I agree.

[@castein98]

Do you have a picture of the finished bathroom. Thank you for the video.

[@mokdadus]

Can you notch or drill diagonally instead of perpendicular to the joist? Example would be moving a gas line diagonally through the kitchen.

[@AlanEdlund]

how did you get your pipe in? did you have to section it a bunch and use straight couplings?

[@chippydog2]

How does this work with engineered I Joists ?

[@PhillyFixed]

"And then go down into the basement and die" 🤣 I'm working above my living room on a bathroom project requiring me to sister the joists and my 4 year old is worried I'll fall through. I may have put a foot through my master bedroom ceiling once.....

[@JLT2342]

I plan to widen my standard 3x5 ft standing shower to 5 x 6 ft standing shower. The existing drain is 1.5 ft from the wall .So the shower drain has to be relocated to the center of 5ft (or 2.5 ft from the wall). The drain pipe is running parallel with joist, so if when doing that, a 2" hole has to be drilled through one joist (2X10 joist) to meet the center. According to your video, so it is coded to do so right? Thank you so much Benjamin.

[@jimharris1590]

Kids are wonderful!@!!!!

[@rty1955]

I thought I was going to see how you got that ridged pipe thru those holes

[@mikefightmaster]

For better strength and less creaking - split a 2 x 4, screw and glue factory edges to top edge of joists. Makes a much stronger beam stronger floor .

[@Mike-ig2zq]

Hey Ben, do you take electrical questions?

[@Mike-ig2zq]

My son has an older house with detached garage. It is supplied with dual 15 amp breakers at main panel in the house. The wire feeds a small sub panel in garage with 2 hot legs and neutral. I have 4 outlets installed on each leg. ( each leg gfci protected ). Should I be able to run a 12.5 amp quartz heater on each leg? He has 2 heaters but when I try to run both on high, each drawing 12.5 Amps, on separate legs the 15 amp breakers in the house trip. I can run either one on high and the other one at half but with both on high after about 45 seconds the 15 amp breakers at main panel trip. The small sub panel at garage has 3 breakers, none of which trip. I have confirmed that the heaters are on separate legs by unhooking one of the hot wires at sub panel. Am I simply overloading the dual breakers? Thanks

[@BenjaminSahlstrom]

Yes, 15a at 240v is 3,600 watts. You can really only draw 80% of that on a continuous basis so that brings that down to 2,880. With those two heaters you would be drawing 25a at 120v so 3,000 watts which is above the 80% continuous load rating not to mention any other lights or other things that may be drawing some power. You can read more about breakers here: www.mikeholt.com/mojonewsarchive/EES-HTML/HTML/ElectricalCircuitBreakers~20030621.htm Hope that makes sense. The other option would be to replace that two pole 240v breaker and see if the old one was just going bad or something like that. Good luck!

[@Mike-ig2zq]

@@BenjaminSahlstrom Thanks alot Ben for the quick replly! Perfectly understood. I was afraid I was pushing the 80%, just wanted to confirm with someone I trust. I'm self taught and some things I haven't had much experience with. And yes I was going to try a new set of breakers seeing as they are probably 20 yrs old. Thought I'd ask you and see if it was worth a shot. Thanks again!!!

@@arthurleslie9669 Ha! In this case I'm actually serious. I can think of ways to make a clean hole through concrete block but not without power equipment.

[@arthurleslie9669]

@@BenjaminSahlstrom Now that surprises me. It takes a little practice but I’ll give you the nutshell version. You start with a short piece of rigid conduit a foot or so long. The size hole wanted determines the size conduit. You can leave it smooth on the business end or, if preferred, file around the end creating very small teeth. Place the business end flush against the block and strike with a hammer. Determining the amount of force is learned through practicing. Slightly rotate the conduit and strike again. Repeat. Done properly, you can actually achieve a nice clean hole in no time. Like I said though ... it takes a little practice.

[@mangravy2000]

Create a fine water stream using a garden hose and a DIY nozzle. Introduce an abrasive into the water stream and some unknown time in the future you'll have a clean circular hole. Of course use a guide for size and uniformity but you get the idea. Hopefully you can use the runoff to refill your swimming pool that you just finished resurfacing the bottom.

Two concerns: 1) If the hole is going to encroach the "danger zone" of weakening the edge, why not sister another 2x8 to be sure it is strong enough? 2) The smallest daughter wasn't seen to get her turn wearing safety goggles!
