Supply plumbing and DWV

[mnicholet]

What do you think about this DWV in the same conduit as the supply plumbing?

What room is that??? Hard to tell whats going on there. Are you sure thats not a water softner drain? Could be something else but hard to tell from that pic.

It is the crawlspace. I traced all of the lines. It is the exit for the DWV and the entrance for the potable water.

That's how it's done. Be happy they put it in conduit--sometimes it isn't. The conduit is only to protect the pipes from crushing by the house foundation/wall structure. Probably only about 3 feet in length. No problem in my view.
