Plumbing Drain Lines Under our Slab

Time to get started on a mountain of slab prep work! The first step is figuring out our drain piping under the slab. Can't get this wrong, since there won't be any accessing it ever again!

ABOUT US: We are Alex and Elaina, a couple in our 20s who are currently living on the 3-acre farm in southern Pennsylvania where Alex grew up. We have a garden, backyard chickens, and build or fix anything that we need to. We still work corporate day jobs, but are working to eventually leave the 9-5 lifestyle in favor of a self-built, debt-free, homestead on 6 acres nearby.
We upload a KZbin video every Saturday night at 7️⃣pm EST, and post daily on Instagram!

I like the pro people, taking care of every detail👏🏼👍🏼

[@musk4mars116]

I'm an architect and DIY builder. Looks like careful work to me. Many DIYers take much more care than a typical contractor. I know I do.

[@shenoyglobal]

do you do MEP Design?

[@terrencewatkins9311]

You did better than my helpers that have been plumbing for a year could do 😂 fantastic job man

[@MasonDixonAcres]

I appreciate that!!

[@softde]

Good energy!

[@lindyok5328]

Hello from OK-great job Alex, you are getting off to good start. Look forward to your weekly progress 😎

[@sovanlalhati5867]

Very nice plumbing 👌👍

[@MasonDixonAcres]

Thank you!

[@brandonp8461]

Love the video, thanks for the great content

[@MasonDixonAcres]

Glad you enjoyed it, thanks for watching and supporting us!

[@user-rv4dt5lo2x]

looks good but i see you did not put a riser pipe 15 ft tall with test caps on each riser to have static pressure on the drains to check for leaks before your inspection,it is required in Alabama maybe not where you are from .

[@MasonDixonAcres]

That's the next video 😉

[@Anime1986X]

sawzall Is convenient for for cutting quickly but for a better cut and more accurate plugin or a Battery operated chopsaw is the way to go

[@MasonDixonAcres]

I like that suggestion! Never even thought to use the chop saw

[@ericnelson8788]

Your toilet isn't vented everything is dumping down on it with no vent

[@MrNeptunebob]

Some things I wonder about: Only 1 bathroom? I would think a floor drain would much larger, up to 4 inches. Would it be better if the kitchen drain line were 2 inches, especially if you have a garbage disposal?

[@MasonDixonAcres]

check out our other videos to get a better idea of the floor plan, all the living space is upstairs. Kitchen drain line is 2” (far like in this video) and 4” is huge, the whole house drains out a 3” pipe

[@suspicionofdeceit]

The liquid outrunning the solids is a myth, no longer matters with modern smooth wall ABS and PVC.

[@MasonDixonAcres]

That’s interesting you mention it, our septic contractor said similar. I’m glad that’s the case!

[@shenoyglobal]

where is this location of build?

[@MasonDixonAcres]

Pennsylvania!

[@top0nic]

it respect 0 code in my country

[@ghetoracinginc6908]

Pretty sure your toilet needs a vent, and most likely the floor drain too, I'd also recommend a trap primer

[@MasonDixonAcres]

The toilet and floor drain are horizontally wet vented

[@jda6135]

Spotted multiple code violations in this one wow 😯 looking at a lot of problems later on down the line your pipe sizing is correct but trap arm length and not enough vents crazy how in the world did you pass inspection ima plumber in Illinois which is the gold standard for plumbing throughout the USA so the rules I have to follow are a lot more strict but damn man good job

[@MasonDixonAcres]

You should be familiar with a horizontal wet vent. There's only one trap underslab and that is the floor drain, the arm is plenty long (offhand I believe 1.5x pipe diameter is the rule)

[@Blox_fruit_master1]

@@MasonDixonAcres You seem to be as ignorant to plumbing as the person on this video.

[@grantwalker270]

I guarantee you didn't spot a single one but wanted to act like you did. Nice try. What vent do you think he's missing? Pretty basic design, vent has to be within 5 ft for 2 inch. Looks like he certainly is within that. That toilet basically drops straight into main line.

[@vasdj]

what a such error, 2" pipe in the kitchen? no less 3" its recomendated-

[@MasonDixonAcres]

Our code is 1.5" min for a kitchen sink

[@vasdj]

@@MasonDixonAcres the minimum code requires 1.5", but modern engineering "recommends" 3" to avoid the effect of greasy cooking water, also the laying you do is too long for 2" without a manhole cover. the issue is that when The client's pipes get clogged in 2 years, he's going to think about who did it, listen to the advice without discriminating who gives it to you.

[@coltoncyoung]

@@vasdj that's ridiculous considering we have modern cleaners to solve this

[@Blox_fruit_master1]

I am a plumbing contractor for 65 years and never , never used 2’’Pipe for a kitchen sink,I use 3” or a bigger size pipe.

[@jdaz5462]

You could have just bought a set of line dogs at Home Depot for 5 bucks instead of taking the time to fabricate them. They aren't this rare thing that you speak of. Every mason uses them.

[@broskiy77]

"I'm trying to learn" sounds scary. I'd never buy a house made by a DIYer.

[@johnf8877]

He is having it inspected along the way. He has an investment. So you are saying you would have your house built by some meth head who won’t remember your house a year from now?

[@johnf8877]

@@broskiy77 Right now they will hire anyone who is willing to come to work. Never met a builder yet who did’t overpromise and under deliver. Once that final check is cashed they don’t remember anything they told you.

[@Patty-qh3lm]

@@johnf8877 all homes come with the standard taillight guarantee, when the taillights are gone so is your guarantee. It's just the law😝

[@ImYourHucklebery117]

This is all vented incorrectly, you really don't need a lot of time to understand proper DWV. It could have been cheap to do before backfill of dirt

[@MasonDixonAcres]

I’m not sure what you’re referring to. Nothing in the plumbing system is backfilled. Maybe you’re seeing the sleeves that go under the footing?

[@ghetoracinginc6908]

I noticed that as well, where is the vent for your water closet? Or the vent for your tub/shower ?

[@ghetoracinginc6908]

Just realized that's a floor drain not t/s, but unless there's a vent upsteam.. it needs a vent as well

[@coltoncyoung]

@@ghetoracinginc6908 not every fixture needs a vent to vent properly
