- Installing underground rough in plumbing under the cement slab before pouring the floor on the pole barn house. How to install sewer septic and drain lines before pouring concrete slab floor. This is how I did my pvc plumbing under the slab floor. It required a lot of digging and I hit a lot of rocks but I got it done. I decided to dig mine after drilling the holes because I figured I might run over the pipes if I did the plumbing first. You can do whichever order you like. Doing it this way made so I had to watch carefully where my holes were at all times. • Plumbing Rough in Unde... here’s a video I did on my garage build for a little more recent work and a little different.
Well good luck with your projects. Let me know if you have any questions.

Thanks for the work doing this presentation. You are right that there aren't many plumbing under slab videos on youtube. I'm doing something similar next week. This video and maybe a half dozen others have given me what I need to accomplish my task.
Awesome I’m glad you got some ideas between them all and what you already know. Good luck with your project 👍👊
Thank you VERY MUCH FOR DOING THIS! Huge help!
You’re welcome! Glad if it helped.
Thanks for the info smart easy diy!
You’re welcome good sir! 😁👍👊
Thank you for sharing.
You’re welcome.
Thank you for taking the time to teach us that are considering doing our own plumbing project😊👍
You’re welcome best of luck with your project! If you have local plumbing codes make sure to check with them before you pour your floor. They can vary a little depending on where you live.
@@SmartEasyDIYer Will do! Thanks again👍
Future reference for others. Size, don't oversize in drainage pipes. If oversize or too much slope, the solids get left, as the liguids drain away too fast, or don't wash the walls. 3 inch will run a whole house up to 3 baths.
I should do a under slab video for the community.
So many savings that could be realized, by more combination drain and vent properly.
Great work on n a rough site with those rocks. Mostly right on.
Thank you for the comment. Thanks for sharing the tips. Yes I went 4 inch since I have a four bedroom and slope is very important. You should make a video. It’s all about sharing ideas. 😊 Thanks
What if you have 4 restrooms
@@contrarianthinker that is when it goes to 4 inch pipe. Oversizing cost more for materials and will not wash out as good since the water level in pipe is low and want carry everything it lays down and piles up.
Excellent!
Thanks
Thank you so much for taking the time and giving us a walk through I'll be starting my project soon and this is helping me grow my understanding and getting ideas. ! Great Video.
You’re welcome! Good luck with your project!
Pro trick: you can watch series at Flixzone. Been using it for watching lots of of movies recently.
@Zyaire Harlem definitely, been using Flixzone for years myself :D
@Zyaire Harlem Yup, I have been using Flixzone for years myself :D
This guy needs more subscribers!
Thank you so much I appreciate the support! 😊👊
Thank you.
You’re welcome
thank! Very informative!
Thank you I’m glad it was helpful.
Thanks for sharing
You’re welcome!
Thanks a lot for the video..I have a project in mind (a whole house!) and I was interested to see something actually being done.. I had to laugh when you said "this drawing is not to scale"...but then you said each square represents one square foot.....and I relaxed..lol...great job...
Thank you! 😁
Good luck with yours!
I like your green shirt.
Thanks for the video.
Haha thanks! 😁
I can’t find your other comment it disappeared.
I'm sure your baby is proud of you.
And I see he is working hard too.
Yes he is. 😊
But after all I want to say thanks for your video.
Is for me a good help when I decided to be a plumber.
Thanks, good man.
How deep do you have to dig per code below finish grade/ concrete.
for the powder bathroom I would have use one 4" y then a 4x2 y with an 8th bend to catch the sink....running one pipe instead of two
That makes sense. Thanks for sharing
Do you backfill these trenches or just pour on the plumbing directly
First, thanks for making the video. Why did you choose PVC over ABS? Out here in my part of Nor-Cal, no one uses PVC for waste. Not sure if it's code or custom though.
That’s weird yes all we use is pvc here. That’s code.
Thanks so much for your videos! I know you reference TH-cam videos for plumbing underneath a house. Is that how you learned plumbing, electrical, and other trades, from TH-cam videos?
You’re welcome. There actually wasn’t many videos about it when I started this but there have gotten to be a lot more nowadays. I knew most of the stuff prior but some videos give some good ideas.
@@SmartEasyDIYer It seems like it would be really tedious to learn the trades by watching TH-cam videos, and I would not feel the confidence I'd have from going through a course, but the course I've seen for aspiring professional plumbers was quite expensive at about $750.
Yes I wouldn’t trying to learn everything from videos. We try to give some ideas and suggestions but you can also get a lot of mixed information sometimes. Not knocking on anyone that’s just how it is with anything, everyone has those own way of doing stuff and they aren’t necessarily wrong in their application but it may be wrong in yours. If that makes sense.
It would help if you know a plumber to bounce ideas off of. If not the course will probably be money well spent for you.
Thanks so much for the gift I really
Didn’t expect that. Much appreciated! I wish you the best going forward!
Why do rough in plumbing before planting poles and perimeter concrete forms? What are your references to line up water and sewer connections so they line up?
I just did the holes first Because I knew it was gonna be a lot of trouble getting the holes in cuz of rocks. I had to drill and jackhammer to get them in. I figured if I did plumbing first I may run into it or damage it. That was just my personal situation. I just setup my strings and used that for my reference to measure off of.
Very informative. How much did that septic tank cost? Where did you get it?
Thanks. I got mine from a local company that made it. I had to get a contractor to install in though as far as the permitting process so he purchased it. I’m not sure how much for just the tank but it was 5.5-6k for the tank and drain field installed.
be interested to see a diagram of how it all works, and how deep to prevent freezing in winter.
I’m not much good at diagrams. So the only concern of freezing in the winter is the traps that hold water if you were to leave your building unheated so you could put in rv marine antifreeze in that case if you left for long periods. Just for general use though if you do it deep enough and it works correctly the water just drains out so there’s no issues.
Thanks for the info, @@SmartEasyDIYer
You’re welcome!
What about the u pieces under the toilet and sinks do you put them in ground too ????
Your talking about the traps? You do those under the sink when you hook up the faucet drains and the toilet has one built into it so no need for one there in the line.
Do you need any qualifications to do your own plumbing?
I’m obviously planning on doing a lot of serious reading and getting info from people I know in construction, but just wanted to know if I could just so it myself.
And then who do you call to come and inspect it? Do they give you pointers to correct small mistakes? Or do they just nail you on the spot and that’s that?
Good question. I think it’s definitely good to research your area, your state, county etc. every area is different. Where I live they let me do my own plumbing without a master plumber involved if it got inspected since it was my own personal property and for my own use not for commercial use. Some places you have to have a master plumber to even pull a permit. The best thing to do is to check with your local county building department because they will be the one to issue the permit and inspect it for you so they will know all the info. You can usually find info on their website for research purposes.
I;m watching this whole playlist and I am curious, did you make use of an architect or did you build in an unincorporated area?
Yes I think you could say that. They don’t use that term here but not in city limits if that’s what you mean.
Just a tour of someone else's completed job. Would be helpful to the rest of us if actual actions were reviewed. How did you dig? How did you put down the pipe? how did you level? How did you make sure the pipe was supported underneath so that when you replaced the soil, the pipe didn't bend under the weight?
Yes I get that. I dug with a backhoe in my situation cuz that’s what I had. I’m not sure what you mean by how did I put down the pipe. I have a trick for using a level that’s simple to get correct slope. th-cam.com/video/AkAGewA2aJM/w-d-xo.html here’s a video for that. I tried to only dig a little at a time so I didn’t get too much for disturbed soil underneath. I would recommend bedding it in crushed gravel that’s packed nice though and also cover it in gravel or dirt that’s free of large rocks to protect the pipe as you’re covering it back up at least until you get a few inches of dirt over it. Hope that helps.
Back fill is all with premium fill and if pipe is correct depth , grade, and bedded well there should be no issues. This is not something that should be undertaken if you aren't experienced with it as it will be very costly to repair and could make your house unlivable. But that being said it's not that difficult
Do you have to get an inspection at this point before the structure and slab pouring?
Yes, usually they tell you when they need to see it.
Can you tell me what area you live in? We're building a pole barn home and I'm a little worried about plumbing in a slab in winter. Slabs aren't common here.
Yeah good question. I live in MT. It gets very cold here. My plumbing ended up being a couple feet in the ground but I also have radiant heat in my floor so I’m really not concerned about it getting too cold. For the most part there shouldn’t be water sitting in the lines to freeze anyways it just drains on out if that makes sense.
@@SmartEasyDIYer Im in Wisconsin, and we need out pipe out to the septic below the frost line, 4 feet here, per code, also I surprised you are allowed to do the plumbing on a new construction, most states require a Master plumber for new construction, remodel in most places is a different story. Same with Electrical for new construction, generally a Master Electrician is required to install. if you can do this legally, you are freer than most.
For your 4" did you use schedule 40 or 80 ?
Hi Rob I did sch 40 for all of it.
I'm just curious, did this installation pass inspection?
Yes
Im a total amateur here. Is it ok to tie sinks/showers/floor drains all into the same drain your toilets use? I understand you use p traps but im just concerned about the possibility of sewage backflow into my non-sewage drains. Again, I know nothing about this stuff but welcome any advice. Planning on building in may and need to get this rough in stuff knocked out in April. Also, how do you know exactly where to center your toilet drains? Are all toilets pretty much the same distance from the back wall?
Yes it usually all gets tied into the main line which will end up in your septic tank. Most places don’t let you separate grey water and sewage anymore. Usually toilets are 12” center out from finished wall. So if you do 1/2” drywall thickness you would do 12 1/2” center out from framed wall for rough in. Baseboard thickness doesnt matter cuz it’s down low. Hopefully that makes sense. Make sure to do your research so you know what’s allowed in your local area, permits inspections etc. good luck!
th-cam.com/video/rd6qO-bfg5E/w-d-xo.htmlsi=XCghIr9mahLyeUTN You might also like this more recent video I did on my garage build. It shows separating the grey water from the septic as an option.
Using 4", PVC and the way you piped, I don't think you'll ever have to use your clean outs
Thanks I don’t plan to but just in case. No issues whatsoever! 👍👊
The vent pipe upstream of the toilet at 3:51 running horizontal underground is a dry vent and is not per code. If the pipe were to backup waste will fill the horizontal portion and block your vent and you would not know it. Of course it’s good that you plan to install a clean out in the vent but it would be better to make it a wet vent and wash it with another fixture.
How much should someone expect to pay for rough-in plumbing for a new structure, connecting to a pre-existing well and septic tank?
That can vary a lot based on location, digging conditions, how many bathrooms etc. I would guess anywhere from 5-7k on the low end to maybe 15-20k on the higher end but that is very much just a guess since I’m not a plumber.
Did all this plumbing pass inspection?
Yes
@@SmartEasyDIYer Cool. I am going to have a 45 with a Y branching to the sink, toilet, and shower. So you confirmed what I was wondering. Thanks!
The septic tank looks big. 3,000 gallons?
I’m not actually sure. I was thinking it was 1500. It does look big yes. It’s for a 4 bedroom. I didn’t install that part of it.
@@SmartEasyDIYer
Looks like there are 3 lids (covers) on the tank. That means, there are 3 chambers in it. And if the depth of the tank is about 5ft. And the width of the tank about 4-5ft; then, it is very likely your is a 3,000 gallon tank. Big enough for 3 generations under one roof.
If you don't mind: price of this tank?
Yes one lid is where solids come in, one is for the solids/liquid filter and one is for the liquid side of tank. Mine is a gravity pressure system since I had enough drop I don’t need a pump. I can’t remember exactly but I think around 4- 5k for the tank and drainfield together.
@@SmartEasyDIYer
Good price. One guy on youtube paid 6-7k for a dual-chamber tank (2 lids), 2000 gallons total. His tank looks like yours, just shorter.
Thanks. Are you planning to do one soon?
So you don't need p trap for showers?
Yes I added them once I saw exactly where the drain went. It’s easier if you do a 16x16 square box made of boards to pour the concrete around that you can remove later when you’re ready.
Nice, I might be a little concerned about being close to that one rock?
Thanks. Well the whole house has a solid rock shelf about 2 feet down so I don’t think it’ll go anywhere. It’s not just one big rock the whole area is rock 2 feet down.
Makes perfect sense.
Are you afraid the million year old rock will move or the plumbing that is backfilled will 2 feet of dirt will move? lol
Crazy to bury pipe into concrete.
People did it all the time. As long as it’s done correctly you should be fine.
@@SmartEasyDIYer Murphy's law.
What would you do crawl space instead?
It is done thousands of times every day.
3inch.pipe cannot take care of 3 bathrooms on the HORIZONAL.
I only have two bathrooms.
Did not even mention what the proper slope of pipes are !?!? I have to ask myself what benefit can I take away from watching this video?
I believe it’s in there somewhere. Should be 1/4 inch per foot slope pretty much standard everywhere for drains.
@@SmartEasyDIYer It's 1/4 inch per foot for smaller pipes. Less for larger pipes. But, hey, there are thousands and thousands of videos on TH-cam that people make - some good, some poor, some lacking critical information, some giving incorrect information. You may not care what I think, but if you are interested in producing a higher quality video presentation, then I suggest you make the video and then preview it yourself. Maybe have another person view it - before uploading it to TH-cam. Movie Directors often do several "cuts" before they are satisfied with the final product. Do as you please.
You could try the 1:27 part of the video where I mention it’s 1/4 inch per ft slope. There are certain applications where it’s 1/8 inch per foot but for the most part anything septic related is 1/4 inch per foot as far as I’ve ever heard. You’ll have to check in your local area though to be sure what’s acceptable.
@@SmartEasyDIYer Sorry, wrong! Slope is based on pipe size - per plumbing code book. I'll avoid reciprocating by making smart aleck remarks. You are clearly unteachable and ungrateful. Goodbye forever - hint - do not bother to reply
I really don’t see that I’ve made smart aleck remarks. I’ve simply pointed out that I do mention it in the video which you clearly skipped over. That’s ok. Please check your local code to make sure before going ahead with your project. Different areas can vary. Good luck.
Your content is informative but your video shakes and make viewers motion sick. Please use a stablized when you make a video and use professional editing software to further stabilize your raw footage. Thanks for showing your fantastic house work.
Thanks yeah I had a bad camera as well at the time that didn’t have image stabilization and didn’t realize how bad the footage looked until it was too late to go back and re-shoot it.
I edited it the best I could but it actually looked worse if I took too much out of it so I just had to go with it. Sorry man
He opened the video, apologizing for the shaky footage. As a videographer, I was well aware of what I was about to watch because he mentioned it at the beginning of the video. He was already aware that the video was shaky, which I was okay with.
