Need help before we pour concrete

[sgmccool]

I'm building a 32x30 garage and before we pour concrete I'd like to stub some piping for future water and a drain. I'm using 2x4's for the walls.

1st question is should I come up where the 2x4s are and then have to cut holes before the get laid down or just come up past the wall.

2nd question, is there anything else I should stub for?

Thanks
Sam

PS does 27K sound good for a dried in 32x30 3 car garage with a loft. That's about $28 a square foot.

There will be a lot of answers to your questions. I would place plumbing in walls where I could. Normally, a wall with plumbing is called a wet wall and is 2 x 6 because of any drain, waste and vent systems that require too much of the sill plate to be cut out. Also, the fittings may not all fit in a 3.5 " space.

Personally, I would come up just inside the walls (leave 2" room for sheathing, fittings, etc). With a 2x4 wall you don't really have the room inside of the wall, especially for waste water/drain.

i would frame with 2x6 i'm not sure but i think here in oregon it might be code

Interior wall?

We don't run plumbing in exterior walls here unless there is no other way around it.... then it'd be able least a 2x8 wall, though double 2x6 or 2x8 is common as well.

2x4 wall is just not enough room. I didn't run my airlines in the wall of my shed for that reason. Would have drilled out WAY too much of the stud to keep me warm and fuzzy.

if your going to have a sink or bath room where ever it going to be just frame that section of the wall with 2x6

hell yeah dont forget electrical!! cheaper to run pvc< and faster> than emt, atleast to get to the other side of the shop

X2 on no plumbing in exterior walls if possible and 2 x 6 framing for walls with main drain line in it.

As for price, sounds good to me, my 28 x 42 to that stage is going to be about $60,000 but I have 14' shop walls, 2 x 6 framing on the first floor, a full second floor with 9' walls, a 300 sq. Ft. deck and interior framing on the second floor driving up my costs some.

Even in Atlanta, having plumbing in the walls is not a good idea. I've had coworkers who had houses with plumbing in the wall, that froze during some of the extended cold spells we've had in past years. I was in a rented cottage in the country in the mid '90's and had bathroom sink plumbing in the wall that froze during a cold snap. Bring it up inside.

Thanks everyone, Come up inside the walls. I plan on stubbing for a sink and electrical. Thanks again

Don`t forget when you put in your conduit under the slab for power phone alarm wires etc use a bigger diameter pipe than you need for future additions.
