What are these pipes for in the basement.


We have an unfinished basement and we were wondering if anyone would know or could tell us what the 3 pipes are for going into the concrete.

Typical bathroom rough in.

However I don't see the vent for the toilet---should be another 2" pipe near the 3" pipe.

I am not a plumber, but I have a pretty good idea.

Top left is a clean out going to a main sewer section. It has a drain or a vent
on the left going up.

Small one below is a future section drain to a sink or shower.

Big one on the right is a future connection to a toilet.

Well, these are for drainage.

Run water into the pipes---see what's going on----Look for the toilet vent----

Any plumber worth his salt can check that with a sewer camera and find the vent or the lack of one.

Not necessarily. The applicable code where I live (IRC 2003) handles venting quite differently from the UPC. Among other things, it does not require vents for toilets. Vents provide an air path to prevent water from being sucked out of the traps. Well, a toilet is essentially a large trap you WANT to ber sucked out when you flush.

Thanks for the replies. Very helpful. So if this is typical rough in, and if we were looking to have a sink, toilet, and tube/shower, could we put a sink in front of the toilet with the sink drain running down to the toilet drain, and then put a shower on the left side of the picture in front of the cleanout?

You can put any fixtures you want there. Looks like you have a 4" building drain servicing that area. You just need to make sure it's plumbed correctly.
Sounds like you plan to remove some concrete?

Here is a quick and dirty picture that I drew up of the top view of the drains. Hopefully this helps better explain of what I have. I guess my biggest question is, would I have to break concrete? I would like to put a bathroom downstairs and will eventually but it will all depend money. Seams like breaking up the concrete, if I have to, will be a big expense. Hopefully the pic. turns out, if not I will repost again.

e plumber or someone else with long term permitable plumbing background correct me if i am wrong but the basement bath since on a different floor can not be vented through the 3 inch drain

and if that is true then start looking around between floor joist for a pipe just hanging there to be used for vent i know irc states if roughing for future use bath a vent most also be roughed in

but that is only if done to code and inspected
