How's this DWV?

[orbea1]

Looking for input on my DWV for 3 lav's.
Planning on everything being 2 inch cpvc. Assume 1/4 slope for the horizontal drain.
Questions:
1. The 90 elbow will be in a stud wall. Will that work?
2. Do I even need the vent for the double lav?

Close but no cigar! On the 2 closest to the verticle drop you have constructed an s-trap. Review your use of horizintal sani-tees.

The furthest fixture on the drawing is fine only if that vent is 42" up before it goes horizontal.


The two lavs need to be vented off tees, combined on the vents and go horizontal as one and on up. That involves 42" or higher as well.

All the vents must be 42" above the floor before they go horizontal.

The fixture drains must connect to the main with a wye and 45, not the santee shown.

[orbea1]

Horizontal vents will be at least 42" above floor or 6" above flood level of the lav.

Is the 90 Ell in the wall going to be OK?

[orbea1]

Thanks. That is actually a third lavatory. But I will make all the vents the same height.

Your welcome . thougt was a shower pipe it like the other two good to go.:)

[ltnicks]

the 90's will work in this scenario, the drawings look good, only the numbers for pitch, height, minimum, and maximum are left out.:)

I see some offset joints. Might get a clog there :)
