- www.homebuildin... Click on this link if you're looking for more information about wall framing, plumbing and structural engineering. This video will provide you with a few examples that can be used to avoid drilling through structural components like window trimmers and king studs for plumbing drain or vent pipes. Remember to check with local building authorities, engineers or representatives from your local building department to verify all of the information in videos like these, because building codes changes and modifications might affect your future construction projects.
A little something not everyone may be aware of. King studs aren't there just to take vertical loads. They also have to carry horizontal loads, wind against the face of the wall. That's why doubling up the king stud doesn't always solve the problem.
People often underestimate the power of wind. Next time you're driving down the highway at 60mph, put your hand out the car window (keep the other firmly on the steering wheel!) and feel how much force is pushing against your hand. Your hand is only a few inches square. Now imagine a strong wind hitting a window measuring 3x5 feet. That's what your wall has to resist.
Very good point and sincerely appreciated.
Always love this content. Speaks directly to my current problems every time I look up your videos
Glad to hear it!
Good point
Great video, Greg. I remember one instance where the Plumbers Apprentice went through a Lintel, and left it, only to be found be me the next morning! It was incredible !
I've never got to see that one and was wondering how long you've been in the construction business?
@@gregvancom Greg, I have been in the construction, inspection, land development, mortgage lending and real estate fields for 43 years in Canada and very briefly in Colorado. In that time, let's just say, I have seen a few things!
By the way, I have a friend that is of Dutch ancestry. His full surname is Vandercooy but he has adapted it to be Van due to the difficulty of others to pronounce his real surname. Do you by chance have a Dutch family connection?
I have been plumbing for about 20 years.
The first time, I found a person who knew what he was doing.
I still have a few mistakes I need to fix, but you do have a good point, there is a lot of wacky information on the internet about rough plumbing.
Building a duplex in Phoenix and framing comes next. Cool to see these videos that are super timely for me.
Glad they're helping and thanks for letting us know.
We wanted to run through the king stud with a double stud, heavy duty stud shoe around the pipe, and the inspector still rejected it, which seems non-sensical if the concern is weight bearing integrity.
As a cabinet maker, this would drive me insane.
Been there plenty of times and I think the biggest problem for me was simply making one of the drawers smaller.
Hi Greg, awesome video. I have a similar problem except with a freestanding tub that we want to install in front of a window.
You can do it!
The trap are distances ie. 30, 42, 60, 72 etc are specific to the trap arm distance. It is to keep the p-trap for syphonage. This is per UPC, and the IRC and IPC are less restrictive. This is not the same as the under floor horizontal drainage is unlimited in length. Table 703.2 of the Uniform Plumbing codes has all the answers for you. Great video.
Don't forget to check with local building codes, they could be different on some situations.
@@gregvancom That generally doesn't happen in the same state, California plumbing code is adapted from the Uniform plumbing code (which started in the city of LA). I have not seen a local amendment that would alter the matimatical probably of the DFU count. UPC is very strict on their opinion on this. 1924 The hoover code, the first plumbing code did the scientific testing under the order of President Hoover and has been the basis for US plumbing code since. The book is out of print, by the Bureau of standards. It is "archived" by good books for free. "RECOMMENDED MINIMUM REQUIREMENTS FOR PLUMBING"
IN DWELLINGS AND SIMILAR BUILDINGS)" very interesting history.
I've seen a lot of track homes where the kitchen sink looks into the livingroom with a conter/bar. They have to drill threw the king studs to vent. and theres a 10 foot opening. Now you got me thinking how they did it.
I've seen it done myself on load bearing walls and pass inspection.
Hello. I have the same exact issue, thank you for your video. It clears alot up. One question: I go around the king stud, does the vent pipe have to be at a slope or can it go horizontal? Thank you.
Yes, the vent pipe should allow water to drain towards main waste drain.
Nice video. Most kitchen sinks have a window in front of them so wonder how they did it in the past? Maybe also double up the short leg under the window and bolt the studs together for strength
I started working in construction in 1978 and every plumber drilled through the kings studs and I'm pretty sure most of those homes are still standing. Structurally though it doesn't make a lot of sense.
FYI notching and holes provisions are in the IRC (International Residential Code which is limited to 2 story structures) but not the IBC (International Building Code, all structures). The IBC limitations are for the reasons you gave for multi-story buildings. I’m not familiar with other code publishers.
Other than those you suggested, you have some states like California and New York who have their own building codes.
For a raised foundation (I guess also for slab foundation too), can a loop vent be used here similar to what is used for kitchen islands? I would think that would work and avoid drilling through the king studs unless the code states loops vents can only be used at kitchen islands. That way all pipes stay within walls.
That's what I'm thinking of doin..got the same question.
Guessed AAVs not to code in CA?
Not code in Los Ángeles california.
Hi Good afternoon Juvy checking can can I go around outside the wall house or need to be inside
Most of the time, but you might need to check with your local building department.
thanks a lot Greg, that's exactly what I'm talking about, I'm in OC
I spent a lot of time working in Orange County, California and don't think I will ever drill through a King stud without the city or county building departments approval.
@@gregvancom thats what the framers told me
Hopefully that first example would fail inspection. Vent needs to go 6 in above flood level before going horizontal. Great video!
According to most of the plumbers I've talked to, there are special circumstances in the building codes that allow for vents to be installed like this.
Yes that is correct. In instances that do not allowed this due to the structure, then it still works, but it has to be pitched 1/4" per foot. Normally vents can be flat. In this case, if drilling through, it best (and harder) to drill at a 45 degrees to the FLR and your golden.
Greg,
I am facing the problem where I cannot drill through the king stud, in my case it would be a post cause there will a post on top of the window header that support a wider window above. This is single story house with 12ft walls & cathedral ceiling.
I am thinking of using back venting method underground with wye rolled up 45 deg and run it pass the king stud (post) so no need to bore/notch the kings stud and trimmer.
Do you think its complianced to code?
I am looking for a video that better explains vertical hanger supports referencing the 2018 IPC table 308.5 note D. (CPVC) " such Gods shall prevent pop movement in a direction perpendicular to the axis of the pipe" 308.7 axial movement
Great suggestion for video and I will put it on our list of videos to be made in the future.
Just use six-inch studs.
Could you have a wider header and then run up through the header on the inside of the king stud?
I don't see the advantage, but as long as the header is structurally supported by trimmers, then it might work.
Are you allowed to drill through the 3 beams that support the window? I'm looking to maybe put a 2 gang box under the window in my master bathroom
Most of the time a small 3/4 inch hole through the framing studs is acceptable. Keep in mind that I can not provide engineering advice.
If the vent is going through the double top plate, does it continue through the roof 1 foot from overhang gutter?... Seems weird looking from ground.
Yes, through the roof and you can always turn it and run it into the attic about 3 or 4 feet if you need to.
I have two sink drain outlets under my kitchen sink which sits directly below a window. What are the chances they are both vertical drains or a dirty arm? I may need to lower one of the drain stubs in the wall, but if its a horizontal dirty arm I don't think I can do it without ripping our the cabinets which I can't do.
The two arms where probably used for each side of a double sink. I'm only guessing, but you can probably just cap the upper one and use the lower one for drain.
@@gregvancom I did some exploring in the pipe using a light and scope camera and they are both horizontal and curve toward each other to a vertical pipe in the center. So essentially both would have to be lowered at once.
Is there any way that you'd be able to show us how to hook up plumbing to an existing septic tank? As I have a second house so to speak in the back of my house with no plumbing?
You can connect to the drain pipe going from the existing home from the septic tank if that's possible.
@@gregvancom thank you I appreciate your advice, and I love all your videos I think they're the best
@@gregvancom I have one more question. Was wondering how I would be able to get running water to that second house in the back of my house? Do you have any ideas?
Hey Greg, question.. i have a slop sink in the garage that i want to relocate with out moving the pipes through the wall. It's that possible?
I would think so, even thought local building codes might not want to see it. For example, you could move the sink and then put it back in original place if there was ever a problem with building codes.
Nice
Glad you liked it and thanks again for commenting.
There are three ways to deal with venting under a window, one is to do an Air Admittance device which has it's own restrictions (which may not be code in your area) or to do a Bow Vent, which runs a vent loop in the stud back down under the floor. The other way is to run through the cabinet to vent.
Air admittance valves might not be allowed by your local building department. It's a mechanical device that could fail and good point about the venting in the same way as you would kitchen island. If something is allowed for one part of the house, then it should be allowed for other parts.
@@gregvancom Honestly I think it's more about people putting inside a wall then under a sink.
@@gregvancom Air Admittance Valves (AAV's) are controversial, because they are good for the fixture, and good for economizing the venting pipe and roofing, but they are not good for the sewer/septic system as a whole. Plus, they are a device with moving parts, that is prone to failure, and the consequence of this failure is flammable smelly gasses seeping in to the house. The sewer and septic depend on conventional roof vents, so there is bidirectional flow of gasses, with the sewer gasses venting throughout the system at each customer's house. If AAV's were used everywhere because of their convenience, and not one standard vent were used, the sewer system would build up a positive pressure of gasses.
Plus, AAV's have the problem of being a maintenance item the home owner may not know they even need to think about, and then after a decade, the valve fails and unexplained sewer gas seeps in to the home. This is why it is common for standard vents to be required in new construction, even if AAV's as an alternative are allowed in existing construction to fix an illegal unvented drain.
Newsflash....
Plumbers don't give a crap.
King stud?
I've seen them cut a floor joist in half!
I've seen it also, but when they have to pay to fix it, then someone might care.
How about a stud shoe? Simpson hardware.
You would need to check with an engineer or your local building and safety department, but as far as I know, they don't always approve them.
Thanks!
On an angle you're never going to get the cabinet installer to work with that.
I've seen them complain and you bring up a good point, maybe let them know in advance.
@@gregvancom how about loop it up and vent it right.
Simple solution just forget the vent entirely just put in a air admittance valve otherwise known as a Studer vent and problem solved its would be installed under the kitchen sink from wall out before the p-trap and it's meets UPC/IPC code so no Boston Loop no Foot Vent No drilling so simple to do!
If you're local building department allows it.
I *Throught* your title was wrong.
Yes, And?
@@gregvancom doesn't anyone know how spell check works?
