Appreciate the sleeve system. Most home builders don’t think past the paycheck they get for the job. Everything eventually wears out down the road of time.

[@HowToBuildYourOwnHome]

Thanks for watching and giving us your insight.

[@raymondpeters9186]

I've been installing pex in pipe for 30 years I install all plumbing in conduit using electrical sweeps to come through the slab Pex pulls in conduit just like wire

[@HowToBuildYourOwnHome]

Yup. Great comment. Wish more would use sweeps and not vertical inserts into concrete. I hate digging under the footing to find conduits.

[@drewtimberlake8356]

Thank you for creating this video. I was trying to figure out the steps to get plumbing/drainage to a shed I want to build that will have a bathroom.

[@tylermundy7985]

Thanks for the video! I'm at this stage right now with a new project.

[@HowToBuildYourOwnHome]

Fantastic!

[@darinjuliesims354]

Keith great. I'm so glad I'm one of your students. I couldn't have done it without you. Funny enough I just had my plumbing inspection and I made a video just before we poured. Watching your video made me proud of myself. It was similar to yours. Thank you for everything

[@HowToBuildYourOwnHome]

That is very kind of you. Please message me through the contact the instructor. I would love a photo of you in front of your build to use as a testimonial.

[@halomat98]

where is the vent for the shower and water closet?

[@HowToBuildYourOwnHome]

Installed later as an internal vent, mainly because we had an open bonus room above with no vertical access.

[@mikeb.1978]

Nice 👍🏽 I didn’t notice any vents?

[@HowToBuildYourOwnHome]

In some areas where it is too hard to vent straight up we use internal venting.

[@iricharddrake1692]

For internal Venting do you mean combination waste and vent because those pipe diameter’s are way too small for that which makes this illegal

[@seaneubanks9549]

No & making a statement with a comment is rude at best. He's talking about AAV for air not waste. Try to be more respectful. He's not getting paid to share his insights. @@iricharddrake1692

@@HowToBuildYourOwnHome - Hey Keith great video, as usual. I am wondering if you might have a plan to do a video on getting trade specific materials? I'm running into issues as on owner-builder getting part for fire sprinklers, but I know some folks that had similar difficulties (HVAC, etc.).

[@Blox_fruit_master1]

Bayou need to learn about your Venting system.

[@elmono3939]

Interesting;.... I wonder what State / City Code this falls under. No clean-outs at the end of 3" lines .... 3" Comby's used in horizontal transitions..... no plastic foam wrap around pipes at slab penetration...with no vent, that toilet will suck out that shower trap once in use ... tons of PEX under slab .... Go figure ... Sometimes I wish I would worked in different States and under such Codes. Life would be so easy for us. Keep building ! Thank you

[@adamr1637]

For residential construction Utah still uses the 2015 IRC. The plumbing sections are similar to the International Plumbing Code.

[@HowToBuildYourOwnHome]

Concrete sub added foam wrap. Clean-out is outside the pad and others will come with second story rough.

WHERE'S THE 1 1/2 VENT FOR THE SHOWER ? AND NO 2" VENT FOR THE TOILET EITHER!! BAD PLUMBING !!

[@GenuineOptimist]

Air admittance vents, installed later. We had no clear line of access to roof with large open space above.

[@RobertBrown876]

I think this is the more complex because of it is not done properly you will have to sledge hammer the floor to realign the plumbing again.

[@HowToBuildYourOwnHome]

True, but we do a lot of slab on grade in my area, guys know their stuff.

[@RobertBrown876]

@@HowToBuildYourOwnHome I'm going to build my own home, don't car too much about inspectiona ar e they are non existent where I will be building but I do want good standards.... What one big pointer would you recommend to layout the plumbing correctly to minimize misplacement errors?

[@chancemows]

I've been watching a bunch of your videos. Love them! May be a silly question, but what is "slab on grade"?

[@HowToBuildYourOwnHome]

A single foundation that is all concrete, no wood floor.

[@wilikisteroyatsh5176]

Nice job

[@iricharddrake1692]

Where is the vents to that toilet and that shower that was plumbed like it was a combination waste and vent in the pipes would need to be much bigger than that that was 100% plumbed to have problems and illegal and if that passes inspection that inspector needs help as well

[@HowToBuildYourOwnHome]

The one vent in the corner bath was an AAV vent (Air Admittance Vent). We have a very large bonus room above with no wall access so not typically stack vent. It is done often in my area with situations like this. Thanks for the comment.

[@iq6840]

Wow, that's some simple rough plumbing. A couple 10 year olds could figure all this out,

[@tarahall1025]

Materials for pipes? Brittle pvc was used on a 2000 build- tied into spigots on side of house just crumbled in your hand- I replaced with semi-flexible pipe- just curious about higher quality materials since they are buried.

[@gst4043]

Where is the drain hole clean cap for the big lines need in the bathroom long lines by the code need one close by the shower area .

[@rociomunoz7384]

thank you for your content! What kinds of utility-related subcontractors or specialists are typically involved in the preparatory work before the foundation is poured?

[@R900DZ]

Why not sleeve the pex in PVC so you can service in the future? Can pipe be replaced without having to bust concrete?

[@jimmybokinskie-reellifevid9623]

DIY commentor here. Can the water lines just be lying on top of the sewer line like that when you backfill? I was told my water line will need to be 12" above my sewer line and on a "shelf" (if they are to share a trench).

[@HowToBuildYourOwnHome]

There is no reason to separate them like that, but some building departments get really nit picky.

[@CourtroomDeputySC]

We try put the sleeves in before concrete .

[@HowToBuildYourOwnHome]

Always a good thing if you know the slope in advance. Thanks for the comment.

[@gst4043]

Where is the vent bro

[@keystoneplumber]

Question, at 3:00 - does that bathroom have no lav? Also how is the water closet and shower venting?

[@joshmccarty1983]

Toilet flushing past a shower with no vent in between 🤦‍♂️

[@HowToBuildYourOwnHome]

There is a vent. Added later above grade.

[@JTTTTx]

Sorry, the vents are installed at the rough in.You have a mess in the making. Please post after you have moved in and are using the fixtures. As others have said- no vents for the toilet and shower. I hope that you have the vents installed for the rest of the project. Possible epic fail as there is no viable correction after the concrete is poured.

[@theonvanhalenn]

When flushing does anything goes towards the shower accidentally?

[@losperez6454]

Different codes Different states, I've plumbed both ways

[@douglaslewis4201]

One code for the entire world. I. P. C. ( international plumbing code) Local jurisdictions can adopt some of their own codes but to wet vent that bathroom there needs to be a vent between that toilet and shower.

[@drickdolla7200]

I wanna know! Did this pass the inspection? I see a number of things wrong in this.

[@stuartray-f1m]

that should never pass inspection .... no vent for the tolit of shower!

[@HowToBuildYourOwnHome]

There was a vent added internally through an AAV valve, or Air Admittance Valve. When you have an upper floor with no wall penetration to vent through the roof, this is a common option.

[@cw4191]

Is that black Polly that you are using to sleeve the PEX?

[@HowToBuildYourOwnHome]

Yes. It comes together when you purchase

[@lduong1]

Good information. Is there a P trap under the tub?

[@MrMusicmaniac23]

Just curious what comes first. Trenching for plumbing or excavation for foundation. Either may be OK i think but which is better done first for slab on grade

[@tuckt6180]

[@thabangmotlanthe5527]

New subscriber here, I like field work but I have not found a junior construction management job, I feel like construction is betraying me

[@HowToBuildYourOwnHome]

What trades do you have under your belt? I would focus there first. I started as a roofer, then an electrician and from there I picked up a lot.

[@mneus]

How are u venting that shower

[@HowToBuildYourOwnHome]

On the other side of shower by sink. Installed later after framing.

[@ryanmiller1840]

You're definitely missing a vent. Inspection failed.

[@HowToBuildYourOwnHome]

Inspection passed. We used an internal vent as the upstairs was a large bonus area with no wall cavity to vent through.

[@FourthWayRanch]

Can you DIY slab on grade in sections?

It comes up through the framework later.

[@MrScottr1958]

No vents required?

[@chancemows]

Is there an advantage of running the sleeved pex under slab vs. running unsleeved through the attic?

[@HowToBuildYourOwnHome]

Yes, less chance of freezing if you run in the attic, for those areas known for very cold winters.

[@chancemows]

@@HowToBuildYourOwnHome Thanks. I’m in Phoenix. I assume running through the attic would be more cost effective?

[@R900DZ]

@@chancemowsadvantage to attic is you can service it in the future without having to bust through concrete… advantage to in slab is if there’s a leak/pipe burst you won’t have rain coming down from the ceiling…

[@adammiller5640]

By running the pecks that way underground the supply lines do you have to have a manifold by the water heater

[@HowToBuildYourOwnHome]

Just a pressure reducer valve if needed. No need for a manifold.

[@shenoyglobal]

how would you do rough plumbing in 2nd floor hollow core slab (walls are concrete)

[@HowToBuildYourOwnHome]

Plumbing would come up through the internal stud-work, which I suggest should be 2X6 walls where plumbing enters from the slab.

[@shenoyglobal]

@@HowToBuildYourOwnHome so you break the slab or make the hole during the casting process?

[@HowToBuildYourOwnHome]

@@shenoyglobal I am not sure what you are asking. I was assuming you were pouring a slab as the foundation. If so, the plumbing gets put in below the slab and before it is poured.

[@shenoyglobal]

@@HowToBuildYourOwnHome i am talking about the 2nd floor precast concrete hollow core slab. how do we get the plumbing to 2nd floor.. we have to punch hole into hollow core slab? or its pre drilled at the manufacturers site as per plumbing plans?

[@HowToBuildYourOwnHome]

@@shenoyglobal First, I would talk with the manufacturer or sub-contractor, or better your engineer. One of them will guide you. May talk with your plumber for best placement of drains and vents and then check with sub-contractor. There could be engineering issues that require best placement. If manufactured offsite, they could install holes. With commercial buildings with concrete flooring, they often drill after, but they make sure rebar is not going to get cut.

[@gst4043]

Shower no trap

[@capn1600]

What type of pipe is the sleeve?

[@HowToBuildYourOwnHome]

Black sleeved.

[@Jpiperdog]

What is that material/product of the sleeve that’s protecting the pex main line? Thanks

[@HowToBuildYourOwnHome]

It is just called sleeved pex.
