Below is an image below my kitchen.
- The drain for the sink. I can hear the water run through it
- Connects to the 3" main drain
- Is this a vent? I don't hear any water going through it and I can't figure out what else it could be hooked up to
- Sump pump
Is number 4 a vent and could I tie into it for my basement dishwasher?
