Rough in sleeves for plumbing, gas and electrical

[bedn0009]

Hello,

My contractor pouring a slab tomorrow for a new garage I'm building. What size/types of pvc/conduit are used for the following:

- Conduit for Electrical line coming from my house to feed a 90A sub-panel
- Sleeve for Natural Gas line run from house for heat
- PVC for future potential water line INTO garage from house
- PVC for future potential waste water drain OUT OF garage

Thanks for your help

Jeff

90a subpanel means nothing because wire size is what will dictate conduit size.

We need more info such as what size wire are u using?

Is the contractor doing the whole build or just the slab?

You do realize that is probably wasn't necessary to post this exact same question in every forum on this site, right? Typically you'll get a better answer if all responses are kept in a single thread, as that way all responses are visible at one time.

Why doesn't your contractor ask his subs what sizes they'll be needing and in what places?

Just run 2.5" for everything. Keeps the radius down on the 90s.
Very vague, re-evaluate your contractor if he's inquiring with you for this information

Wouldn't any "contractor" with his mastery of all things construction and world of experience have a pretty fair idea of what sizes are needed? Just thinkin...

You would think so, I'm not sure what the OP is doing?

why would they be under the slab? wouldn't they stop at the outside, come up exterior wall and then into garage. that's how I normally do my electrical

For my electric feed I used 2" conduit with 90 sweeps to make an easier pull.

mark2457 read slowly -

OP states all the above!
I wouldn't believe 2.5" would be enough for a waste line?

On my build I roughed in 2" conduit for electrical and another 2" for data, phone and ctv. Then I used a 1-1/2 conduit to pull a 1" plastic water line. I stubbed in a 3" waste line but probably should have made it 4" ( I will upsize to 4" at the foundation wall all the way to my main sanitary at the house.) My gas will go up on the exterior side of my foundation and enter thru the stud space. The 2" for electrical will be for #2 copper for a 100amp sub distance of about 130'. I test fit a 1" water line thru the 1-1/2" sweep of electrical conduit and it seemed plenty large at the time. I just stubbed everything up and capped it about a foot above floor line. I knocked a hole in a block just above my footing to run the conduits out about a foot to be able to connect them once I trench the whole thing..... Good Luck!

Whoops - see this was posted back on 7/6....OP should have it all done by now!

 

[wyliesdiesels]

Well i guess the OP aint coming back...

Natural gas should not be sleeved to enter INSIDE the building . . . No, no, no !!

It should come up on exterior of building & only enter above grade (like 2 ft above ground).
