Are your floor joist N-S or E-W on your drawing. That is what determines where you drop to the basement. You cannot cut out a ton of floor joist with the 3 inch runs.

I assumed they were N-S

North being the top South the bottom on your drawing.

Correct. They run N/S. They run perpendicular to the exterior wall on the second floor.

What we are looking for is walls on the first floor that are in the same joist space as the toilet. If interior walls cannot be found then we will need to run down the exterior wall. It is no problem cutting that wall. Just not a preferable method.

On toilet T1 is the 1st floor bathtub wall in that same joist space?

Could you drop the ceiling a bit in the storage built in area. For T2

You have N Cl can we hit a wall there with the washer. Best to use the wall between the washer and the lavatory up stairs.

Notice I'm trying to avoid cutting your joist to shreds.

I agree with what you're saying but the problem with that is the second floor exterior wall is sitting on a double 2x10 LVL because the second floor sits back from the first floor exterior wall about 6 feet.

I'll touch base with the architect tomorrow but I'm pretty sure he said that as long as there is an 1 1/2" of meat on both sides of the joist, I'm fine. I just need to stiffen the joist on both sides with 3/4" plywood the height of the joist and run it 1 foot past the hole on both sides glued and screwed...

T1 is not in the same joist space as the first floor bathtub wall but it is close. I will put an overlay where the wall lays relative to the second floor tomorrow.

I don't think I can drop the ceiling in the kitchen on the first floor for T2.

What do you mean by "N CL"? I might have a better way to run the washer. Let me redraw it tomorrow and I will resend.

What is your name Ghostmaker? Thanks for your help.

Pat

Here is an updated drawing. I think this one is a little better to understand. On this drawing, I did an overlay of the first floor walls available for the 2 bathrooms upstairs. By viewing this, it helped me come up with a couple of other options. Let me know what your thoughts are.

Thanks for all of your help. I really do appreciate it.

Lets work on T1 We will use whats called a wet vent.

We will have a 3 inch 90 turned to the basement at opt2 You will need to run to t1 and use 90 to turn up there. Between the two you need to install a 3 by 2 wye 2 inch towards the lavatory sink. you will need to drill for the 2 inch to and turn it with 90s and 45 fittings to head towards the lavatory, Once at the sink install a 2 by 1.5 by 1.5 inch wye the 1.5 inch branch to the wall behind the sink with a 90 then at 19 inches to center off the floor install a tee the vent will come off the top of the tee.

the other end of the wye is looking at your tub. run the 1.5 inch to your tub and install your trap for the tub.

See if you can draw an isometric of what I wrote.



Above is an example of a wet vent just to give you an idea.

My lousy attempt

Thanks Ghostmaker! I will get the drawing to you tomorrow. What size do you want the vent to be going up from the sink? 1 1/2"?

Thanks,

Pat

1.5 inch should work as long as we get to the vent out the roof within 40 foot

2 inch to the wye picking up the sink and tub.

3 inch to the toilet. This may need to change once we see the joist layout in real world.

Ill work on the other tomorrow
Night now Just call me ghost....

Here is what the architect approved for bracing the 3" or 4" holes that have to be drilled through the floor/ceiling joist.

The ACW and lav 3 inch to the 3 by 3 by 2 tee picking up the washer box. Bush top of tee to 1.5 inch run 1.5 inch to lav and 1.5 inch vent to attic.

A common vent.

The washer box should have a 2 inch trap. Buy one with built in hammer arrestors. You will need to contact your local inspector to see if a washer pan is required. Here they are not. Also see if he wants a pan and if you could just run the emergency drain on the pan to a basement floor drain or if he wants it tied into the sanitary drain. We prefer not doing that here because of sewer gas and a dry trap under the washer. Tomorrow the basement.

Also make that wall this is in a 2 by 6 one.

Does your first floor bath have a 3 inch vent on it? If so you could just run all these vents to it. Just make sure they all are self draining. And supported at 4 foot intervals all your DWV Drain waste or vent piping.

Just extend the first floor vent out the roof if 3 inch keep it three inch out roof.
