It is worth mentioning that shower/tub drain lines should always run downstream of a toilet, so that a clogged toilet will not back-up into shower

I am about to do my plumbing before a 60' x 40' slab pour. This video has so much good information, thank you!

Best plumbing layout I've seen! This makes it easily to follow and understand. Thanks for taking the time to share it with us.

Brother I tell this. That is one of the cleanest plumbing install I have seen, and trust me, Ive been in this business for 43 years and still love it. I do have concerns on water in the same trench as the waste. But otherwise, great job!...😎👍

This video was so dam helpful for understanding some of the infrastructure of the plumbing and what not. Thank you!

Reminds me so much of our kids. They love to be around our business and we have constantly watch out for them. They would also throw stones into pipes...

You are very detailed, I love such accuracy, your films are watched with great pleasure :) Greetings from Poland

this real helps me out rightnow ,been chippy 30 years wish i taken more notice of plumming ,now im building my own house,big help,price i got for waste pipe and septic tank 16000 k here in oz , for a 48 sq home ,string line is the way to go,shaw theres lazers but you still have mark it

Great video. Very informative. I'm building a house in 2 months and this was exactly the information I was hoping to get. Please follow up with more videos.

In the one spot he used a double wye underground.....illegal in Canada as you cant get proper fall on both drains cause one would end up having back fall while the other one has fall

man what a clean job looks slick

i know this is an older video, but I am really enjoying your walk-through. Beautifully laid out

Thank you for the clear and concise description of the process. Really appreciate you taking the time to share.

Great job and much patience. Your camera work is just outstanding, and your explaining is just as important

I’ve been looking all this content you provide I’m getting ready to do my own pole barn house build

So satisfying to watch. A lot of good tips and ideas. Very well performed. Thx for sharing.

The problem with the PEX manifold and a line going to each thing is that you end up with a huge waste of Hot water. Say you use an Upstairs sink hot water and then go to pop into the shower. Now you have to run out all the cold water still sitting in the hot line and drain out all the cold water first as using the hot water in the sink didn't do that for you because it has its own line. For a small house, not a huge deal, but this doesn't look small at all. Looks huge and there's a 2nd floor not started yet.

Thank you buddy, starting a project, best under slab plumbing video on KZfaq couldn't do it with this.

Very nice, a lot of plumbers dont understand the lay down system... Its better than stacking for depth and drain cable(if needed) purposes

Excellent job! Intelligent contractor. Bravo!

Thanks for making it simple and easy to understand

This guy can't be a plumber he's talking about his fittings going the right way. Right there that tells me he's a handyman

Awesome video! I am building a steel barn on my property and running lines for septic and water into it. I have been searching for a video just like this and want to thank you for taking the time to record this to help others out!

I'm really impressed with the way you demonstrate your

The one disadvantage of the pex homeruns is a lot of water is wasted (hot lines). What I ended up doing is putting a hotwater recirculating pump that allows hot water to recirculate through the manifold to the most used faucet (master bath). This way hot water is always at the manifold instead of the hot water tank.

Great video, I recently saw a neighbor's home in SW Florida that used a manifold system for water distribution; that should be the standard for all new build.

Good work on laying pipes in Plumbing well done look.

1. You are smart to insulate the PEX since you are Insulating the slab. See #4 if you don't read all. 2. You are smart to put the PEX under the slab to prevent slab stress from potentially harming it. 3. I like the dedicated runs that both enables sleeving later if it was needed and enables isolation cutoff if work or alterations needed in the system such as changing out sink commode parts etc. 4. One thing that is affected by your layout is the fact that since all the hot water also is in dedicated lines there could be a lot of energy waste heating the water waiting for the hot water to get to outlet or more pipe to heat with record system . A couple ways to mitigate this. A. locate water heater in central location according to amount of hot water usage not length of pipe runs. (doesn't matter if same length of pipe to a shop sink and a bathroom if shop hot water not used much and bathroom is used a lot) B. Little dicey but it is your house. Unless the code is advanced in your area orr open to modification it requires 3/4 and 1/2 inch pipe for sinks etc hot water lines. I would consider running 1/4 inch PEX inside the current PEX after inspection to most locations (maybe not bathtubs) . This will save a lot of the hot water energy because much less cold water is in the pipe to run out till hot gets to point of use. You should have plenty of pressure even in shower if low flow heads especially or you could always try it and remove sleeve if it didn't suit you. ( by the way if on well check out a cycle stope valve for continuous pressure if flow above 1 gallon per minute or a variable speed pump much more expensive and repairs inevitably expensive)

I absolutely love this channel. I am learning so much

I wish they ran the water lines like you did in this house I moved into in Jan this year...It loses pressure in pretty much every bathroom fixture the kitchen and even the utility sink in the laundry room and given it's a ranch style house so everything is under tile & a cement slab.

Fantastic video step by step, easy to understand, and congrats for the neat work

Basements and crawl spaces= easier repairs in future. Slabs are future repair nightmares.

thanks for being thorough

Outstanding organization of your layout. Thanks for the video!

This is the video I've been looking for. Thank you good sir.

Wow! Great details. You answered quite a few questions I was having regarding plumbing and water in slab. We are facing this challenge shortly and I am a little nervous as I tackle it myself. Thanks.

Thats awesome! And I love the way you made it so understanding.

Very nicely done.

I'm doing something crazy, building a house in rural South Africa from America (follow my youtube channel for future vids on the process) and was looking for how to do exactly this so I can tell my plumber when they are doing something wrong. I took some notes cause internet is limited over there. This was very helpful thank you!

bro final lay_out plumbing for PVC pipe there are all setting.GOD BLESS YOU and your FAMILY

Nice work! perfect layout. Any video on the electrical being done in that slab? Thanks!

You like to build things. This is what God made men to do.

VERY NICE JOB.

Great job!

I'm wondering why you ran your PEX under the slab rather than in the walls? I mean I assume every room is going to have a wall of some sort. I understand running the water under the slab to get to the kitchen island that makes sense because there's no wall but everything else should have a wall in which you could just run your PEX. Am I missing something?

What I am wanting to know is how the plumber start and how he takes measurements to dig the trenches and and run all the pipes to the designed locations in a land where nothing is yet built. How everything (bath, kitchen, laundry, etc) matches to the precise location after the house is built?

Thx buddy

Nice work

Well done sir!

Awesome video!

Very nice neat work. And informational. You the man.👍

Interesting, where we are the septic has to be completely separate to the grey water within the building

Hello sir good job anf hatd work so very nice greatfull.

Very nice clean job though

Thanks for sharing, neat work man!

Excellent

Great video, thanks

A lot heavy labor work involved obviously isn't a easy task to complete great work BTW 👍

ABSOLUTELY SLICK WAY TO INSULATE YOUR PEX PIPE AND BRING IT UP WITH THOSE 90’S. Very Organized and SLICK‼️👍👍. Vinny 🇺🇸

I would like after the houses build and used come back in about 50 years and tell me what HASN'T WORKED OUT what WOULD YOU HAVE DONE DIFFERENTLY.....

Just curious, after watching several DIY videos on pouring a concrete slab...my overwhelming question is: Where do people get all this time to do it? PLUS record it! LOL

What's an efficient way to dig the space for the PVC pipe and keep the 1/4 per foot pitch? What's an efficient way to measure this afterwards?

Just had to deal with leaks under the slab. If I build a new house I would never do under the slab. Sheet rock is easier to fix than breaking concrete etc.

Fantastic video! Your work is meticulous. I didn’t seen any primer on the pipe but, seeing how you work, you probably masked off the pipe before priming and then pulled the masking off…LOL. Thanks for sharing!

Awesome

what's the story with the vent in the island?

Another great video!

Rough plumbing get idea where Drains and the Water lines go’

Mani block water system

Don’t need 1/4” slope on 3”. Code is 1/8” makes a huge difference on long runs 1/4 drops to much

Flat Venting and a Double Wye on its back should have been a figure 5 other than that trenches look good and the layout is great

Just curious why you put the pex below the concrete? is it because the concrete can react with the pex tubing? How deep do you bury the pex in the rock?

Can someone explain to me why you would lay down your rock before you lay down your plumbing??

Not just that it plugs up easier, you can't run a drain snake thru short radius elbows.

Should use all Long sweeps Not all the y with the 45s

I would have tested the system with 10' of head pressure, fixing a bad joint would be easier before the concrete is poured.

Ok I might be asking a dumb question but what happens if there is an issue later on with the plumbing. Since it's buried in concrete won't that make it tough to fix? I feel like in a conventional home it's just buried behind drywall. Thanks for posting these videos I'm addicted.

So you just insulated the PEX lines under the slab? No pex line conduit? Just electrical conduit?

For 4” drain lines you need 1/4” /ft slope, right? Looks like your main run spans quite the distance. Did you have a couple feet of total drop by the time you got to the septic tank?

How does the closet flange sit on a finished concrete floor? Did you pour around it so its flush with the finished concrete?

Don't know why you would use regulars on the combos also did you ever put extra fall on the pipe sop that shit would fly ?

Great video. Very neat. What grade of rock did you use?

Just to be clear, you did not have a septic installed prior to laying plumbing and concrete? Thanks

Paul, these videos are awesome! Fantastic explanation of the sub slab plumbing. I will definitely use these videos when I build my building! Do you dry fit this before cementing the pipes? How deep do these need to be below the concrete?

Looks great. Super OCD

Very helpful & inspiring info. Do the 1/2” PEX water supply lines need to be pressurized during the pour like they would for radiant floor heat or is that unnecessary since it’s going to be buried under backfill & covered with 2” blue board?

No expansion joints? Or quarter minus (small rocks) back fill under the pipe.....? Hmmmmmm not good

Don't you need a plumbing inspection where you are before you cover the pipes up??

Is that pex A and is it not recommended to do type b under slab?

You use a vent for every sink, toilet, etc? Can't you use only one vent upstream of the line that takes care of everything downstream of it? Also why a vent on your island kitchen sink if it cannot go up ? thank you!

How many vents do you need

I enjoyed your video, very informative! I was curious how you brought the main water supply in. Was this under your slab as well?

How do you make sure the pipe doesn't flex or lose slope when the weight of the slab compresses it all down? Any way to fix the pipe in place? Rebar?

What is the sub base material is it crusher run ?

Nice clean underground... why can’t they all be like that....

Have you had any clogs since the instal

When you say vent what does that mean? What is that for?

Do you need the inspector to approve the work before you cover it?

Question, the island sink, you said the vent will be done underneath? I assume automatic air vents are approved in your area?

In the video you said 1/4 inch per foot slope. The minimum to code is supposed to be 1/4 inch every 4 feet. It looks like you did 1/4 inch every 4 feet. Is that correct? By the way, that looks slick. I love the home run setup that you did on your water lines. I'll have to utalize that method on my next build because it makes life easier when your in the process of building and installing as well as future maintance.
