Um is this a mess?
 
bought a house and replacing the counter and sink. I'm no plumber but this looks way wrong to me. The dishwasher is dumping after the trap and the water has to go up before going down the drain ?? At least it looks like there is a vent.

Need to go back and add your location to your profile.
Must be below the equator where water runs up hill and sewer gas run down hill.

That sure is a creative use of pipe-----wrong in many ways, but very creative.

It looks like a complete and utter mess. Start at the wall and re-plumb the entire thing is the best way to proceed.

By the way what is that 1.5" abs line for that goes through the floor for?

The abs going into the floor is the drain! Coming out of the wall is the vent not sure how the water is even going down the drain but it works. Guess the only thing stopping the sewer gas is the fact that the drain hose for the dishwasher has a bit of a dip in it. Man oh man....

Maybe a pump from below????? still not code very much in need of a repipe.:eek:

I would have guessed that the 1.5" abs going down was some sort of convoluted excuse for a loop vent. Are you sure it's the drain?

I'd want to know if that's a Tee or just an elbow going up where it goes through that wall.

What's below there?

I can confirm that it's the drain going through the floor. I can see it underneath. I can also see the vent from the downstairs bathroom come up to meet the spot where the pipe comes out of the wall and can see the vent on the roof over this location.

Again : as a loop vent, they usually travel through the floor slope upwards away from the sink, and intersect another wall. As it is now, that line is not serving as a drain (although it may be receiving some of the discharge from the sink), the one in the wall is.

Make 100% sure which is which before you start re-arranging things.

The drain goes to the stack, the vent does go to the vent for the bathroom downstairs (unless the water from the sink drains up the wall)

But yeah I was just sitting here thinking about how the water must be going down that pipe instead of the actual drain.

:whistling2:

Sounds to me like someone might have cut a tee into the kitchen drain for a sink on a lower level. Which is why you're making the comment about water draining up the wall. :huh:

The other line going directly to the stack sounds to me like some form of loop vent tied into the main 4" stack to serve as a vent.

Hard to tell without more visual cues.

As mentioned before, it would be nice to know what's in the wall there ; whether it's a tee or just a 90.

In the wall is a T. Goes up to a roof vent and down under the floor where it becomes the vent for a sink I the basement. That is where the "up the wall" comment comes from The sink in the basement has its own drain.

Ran the water upstairs and hung out in the basement. Can hear the water draining in both pipes.

Since the pipe in the wall is a true drain up to the roof and the pipe in the floor is a true drain into the stack, could I not just make a bit of a loop with the vent pipe and put a T in over the drain to tie in the sink and dishwasher? That way the vent is coming down over the drain? Kind of like a loop for an island sink ?
