Buddahriffic@lemmy.world 3 months agoThere is a wooosh here, though I’m not sure it’s on you or me.
In case it’s you, it is just a bong and doesn’t go anywhere. That bit on the bottom is just the stand and the pipe doesn’t connect to anything below the floor, it’s just sitting in the cupboard.
If you already knew this, then the wooosh is on me lol.
It’s an effective way to hide a bong in plain sight because it looks like it’s a vent pipe. But I do agree with this saying don’t smoke something with a PVC-based pipe (though I’d extend that to say your smoking utensil shouldn’t involve any plastic whatsoever other than maybe o-rings, but my glass-only rig is able to seal well without them).

It’s on you. They’re talking about the 90 degree elbow behind the bong that heads upwards. It’s piped like it’s to a vent, but the location relative to the cabinet opening means the vent for the sink is… between you and the sink

Ah, yeah, I see that now, rereading what they originally said.
Out of curiosity, what is the issue with using a vent 90 degree elbow vs whatever should be used there instead?
Btw, I’m assuming that’s the drain pipe coming from the sink above rather than a vent, especially since it looks like the dishwasher drain is attached to the horizontal part… Wait, is it attached to the bottom of the horizontal section??

Drains should always have a P-trap within so many inches of the drain opening. That prevents sewer gas from escaping from the drain. This is what should be there if it’s a sink drain.
The issue with a vent 90/elbow in a sewer line is that they slow the water flow and can easily become obstructed. Normal elbows are curved to help prevent the water flow from slowing down.

Thanks for the info!
Why does the p-trap need to be so close to the opening? As long as it’s somewhere along the line, shouldn’t it prevent gases from flowing? My own kitchen sink doesn’t have a p-trap in the cupboard below but I assume there’s one downstream because I’ve never noticed sewer smells in the kitchen. I figured it was the developers being cheap as soon as I noticed it, but they seem to at least have prevented the issue another way, so it’s hard to say if they were cheap or just efficient (or maybe neither if it’s just a p-trap in a different location).
My bathroom sink does have a p-trap under the sink though, so I’m still confused as to why it’s done one way in one spot and another in the other.
Only other guess I have at this point is it was done that way to simplify fitting the drain pipes under the sink because the hole for the pipe is directly underneath the one sink drain and it just feeds directly down via a vertical pipe, with the other sink’s drain feeding into that via a y-connection.
