Hi everyone, I'm new to the forum and I decided to come here and ask the experts.

We're building a new house and the foundation is almost complete and I need to do a rough in for a future bathroom and laundry room in the basement. Here is a sketch of the rough in. I want to know if this is how it's done and what needs to be revised or changed before I go ahead and do this.



The Second picture is what it's going to look like once I tie everything together. I didn't put a P-trap on the shower or sink but they will be installed when I finish the bathroom.



The other question I have is a 3" pipe big enough or should I go to 4" for the main drain to the sewage pump basin?

Oh and one more question. Should I be adding clean-outs anywhere?

Thanks guys :)

Where I plumb, you would use wye fittings on the vents below grade, not the santees.
Pretty cool looking drawing though.

I'll make the changes to the drawings and re-post tomorrow.

Thanks for all the help.

As far as the main drain goes. 3" is big enough??
 
3" is good.

Often, the inspector will want the 2" outlet from the pump going into a 4", but you can check with him to see what he thinks.
 
Here are the pictures with the proposed changes.

I put a wye on all vents below grade. I made sure to point the wye's downstream as I read in another post.

On the second picture I plumbed the washer and laundry tub like Terry's picture.

If everything looks good I will submit this to the municipal office for they're approval and permit.
 
You should also check to make sure your check valve can be installed vertically. Might cause some problems if you have a horizontal check installed vertically,

I stopped using fittings in Autocad LT a long time ago. Easier to just draw in isometric.
A for effort though!

yeah all that was done in isometric. I don't have that much experience with AutoCAD so this was a bit of a challenge.

I use it at work mostly to do electronic and wirring diagrams. I never work in Isometric

Check valves can go horizontal or vertical. Here, the washing machine would go directly into the vertical without the additional reventing. That would only be necessary if the trap were more than 4' from the riser.
 
In post # 5 I see a washer drain and sink on 2" I didn't know you could put both fixtures on 1 line. Thats ok?
