Bathroom Rough-in


Hi,

I'm just getting ready to renovate my basement, starting with the bathroom first. I've attached three pictures, the first one showing the toilet rough-in with (I'm assuming) the toilet vent behind it. The second picture showing a pipe coming down from the toilet vent and into the ground with the laundry washer connected to it from behind the wall. The third picture is questionable.

My questions are:
1) Where do I put my sink? Can I connect it directly to the toilet vent and still have the sink drain into the sewer line, or can I connect it to the pipe that is connected to the laundry (picture 2)?
2) If I do put my sink behind the laundry, can I use the opening at the very bottom of the pipe or is that used for a clean out.
3) What is in picture 3? It's located a few feet from the toilet rough-in and just filled with rocks. Is this the shower drain?


Thanks!

Toilet hole should be 12" or 12 1/2" from the studs----

Yes you should be able to use the laundry wall and plumbing for the sink.

Using the toilet vent for the sink is not a good plan.

Hole in floor could be for a tub--1 1/2 " drain or a shower--2" drain--open it up and see what you have,

Answers per UPC-
1 Use the toilet vent for the lav drain.
2 No, that is a clean out
3 Appears to be a backwater valve. It protects your basement from sewer backup should the sewer main clog. You should find another lid below the gravel.

I've dug out the all the gravel from the pit and found a 2" horizontal capped pipe. Does that mean i need to install a P trap for the shower drain?

thanks
