You have a gift for clearly articulating your thoughts, which makes these types of videos of yours so easy to learn from. Thanks!!
I'm planning my own self build in the UK and getting my head around plumbing. Thanks for the help 👍
I was second guessing my ability to rough in my own plumbing under slab until watching this. You've answered most of the questions that I had and I now feel more confident. Thanks brother!
Did u do it yourself? If so how’d it go?
You did a great job of showing what needs to be done under the slab.I have never done a home on a engineered slab on grade before.I do know you get only one chance to get it right before the pour.
Good job, Brother Benjamin and helper! Can't forget the helper....
You can run a continuous waste line and have all the floor drains you want as long as you oversize the vent at the end one size larger then p-trap on floor drain. We do it all the time in car dealerships where there are no walls for vents other than end of line vent and clean out.
Thanks for sharing. Please remember that license plumbers lay straighter pipes….lol
Excellent SMART rough-in work. I love the "strutting" of the sleeves to keep them straight and positioned for the concrete pour. Man, this video makes me want to build a new house!!!
Unusual for you to show us your Master Plumbing knowledge. Thank you
When it comes to venting, like say for a floor drain in the center of a room, if I’m not mistaken you can oversize the drain to the fixture and have an infinite length back to a vent. Like say instead of running 2” for the floor drain run it in 3” to a 3-4” main.
Concrete unless you're referring to the Portland cement which is the "glue". Enjoyed the video!
Good Ole Ben 😎
Thanks for this. I learned some things watching this video that will come in handy when I plumb my little garage/shop.
been waiting for this one...thanks!
That building is YUGE!
Very helpful !!! Great Job.
Great video. Great information. Thank you!
Really classy details that set you apart
Nice spoofing scam
Great Video learned a lot!
As an alternative to using a fish tape, you can tie a nylon string to a plastic shopping bag, and use a shop vac' to suck the string through the pipe. It's fast!
Probably should have started off with the plot plan or floor plan so we see what goes where and why. Do the electricians do their work at the same time the plumbers do? Does the same crew who did the forms help with plumbing and electrical?
You can have things like showers drain wash the 90 that goes up the wall for venting. If you get a backup it can clog vent stack, so a drain can empty above the 90 to wash any debris and clear the 90.
In Sweden we sleave a small pvc/plastic pipe on the rebar, sticking up to support the pipes etc. Just to make it easy to pull up the rebar, when the slab is poured and hardened. Our PEX tubes always comes with a corrugated sleave. Both for protection and easier replacement I guess. Always cool to see how stuff is done other places in the world. Do you use any insulation or capillary breaking material under the slab?
Good idea with Pex thru PVC pipe.
13:14 shows a 3" 1/4 bend placed in a horizontal line from the toilet. That should be a long sweep or 2 45's. That wouldn't fly here in NE PA.
I also noticed that and was going to ask about it.
Nice information you shared you explained clearly and very informative regarding the slopes of waste pipes lines 2, 3 is okay how about 4,5 it it still okay thank you for sharing watching from Philippines
Can you do a video about the square D QO recall, how to inspect and repair the panel?
Where do you even get soild core pvc anymore? All thats available at my stores is that charlotte cellular stuff.
Hello, Ben! Thanks for sharing, I love your videos! Is the 2 in toilet vent connected to a sanitary t or a combo? It looks like a sanitary t but I wanna make sure. Thanks and have a good one!
You should almost always say concrete. Cement is just one of the components (with sand) that make concrete, concrete. So you have a concrete driveway, concrete sidewalk, concrete foundation, concrete blocks, etc. It's like calling NM or Romex a cable instead of wire, because it's a bunch of wires together that make cables.
CONCRETE pretty much always. Cement is just one of the ingredients
I love your videos, and I know you are doing the " right" thing with primer; but over the years, I have found that primed pipes actually make "cold" joints, that break/pull apart, far more easily than non-primed pipes, especially when placed under EXTREME stress....any ideas what I am doing wrong with the primer?
Nice job, what brand of pex are you using?
So the pex water lines just lay right on top of the drain pipe? I saw some other videos saying pex cannot be in direct contact with concrete, I guess those were wrong? Also why not ABS for the drains instead of PVC?
It is important to sleeve PEX wherever it comes out of the slab, but it's obviously used all the time in direct contact with concrete for in floor heating systems. For water lines, I prefer to keep those away from direct contact with the concrete if possible. No one uses ABS in our area. I'm not really sure why.
NOT CEMENT Ben.......C O N C R C T E !
@benjamin sahlstrom how do you hydrostatic the system with the floor drains?
Why not wet vent the toilet? Am working on 40x40 post frame house, and am planning on doing plumbing first before putting up the house. Doing this because I want to build up a layer of 3/4" rock for a radon system below the slab.
You can horizontal wet vent a toilet. Actually a toilet doesn't require a direct vent so a vent can be anywhere on a system. PER IPC
Hey a challenge how do you slope pipe when the toilet is 7 feet to the main at approximate 24" drop
What applications are cellular core pvc used?
You can use it the same as sch 40 pvc. It's a matter of preference. But it is an approved material.
Am a plumber and from Ghana I will like to work with you
Funny how one place to another how different codes are.
This does not have anything to do with the video. But what's the proper way to repair a 1/0 x3 with ground wire when sheathing has been stripped back to far where it goes into the breaker box?
I thought you could nt use a San tee on its back? That’s what it looks like when you vented the toilet
do you prefer pvc to abs? and why
Have never used ABS and no one around here does either. Not sure why.

Concrete, cement... its all asphalt to me
Edit - except the pvc cement, that's paste
Need to rename the Cement trucks to Concrete trucks so Karen's don't flip out.

Splendidly to see Woodglut have new plans which helped me save some money and energy for this construction.
Not stupid necessarily, but man I'm tired of wasting gallons of water just to get hot water out of my tap. RHW needs to become code
what is RHW ??
No structure Dude! Start at the main then stay with supply then drainage. Just jumping around and talking fast could be improved.
