So here's some plumbing in my house (not done by me):
This was before I sealed everything up behind drywall. The drain is actually used for a Cat Genie, our laundry is in another room.
Now we're having an issue where the drain is not draining quickly enough, sending gross water from the fancy flushing litter box onto the floor.
I've got an endoscopic camera down to the wet trap and didn't see anything amiss, but before I tear into the drywall, I was hoping someone could tell me -- does this plumbing job look acceptable? Do you think my problem is here or downstream?
The venting you see is into the wall -- this is on the first floor, getting a vent all the way to the roof in this 80 year old house would be a Herculean task.
Any pointers appreciated -- I do ok with electrical, but other than decent skills with PVC, plumbing isn't my area of expertise.
