grey tank stink
Recently the motorhome stinks whenever we run any water to the grey tank: washing dishes, showering, etc. I couldn't figure out where the smell was coming from. I thought maybe it was coming from...

So, it's definitely NOT the air admittance valves. The smell is definitely coming through the ducted A/C system.
I removed the grey vent and the pipe has not dropped in to the tank.
I shot a high-pressure blast of water into the vent thinking if there was a crack or leak somewhere along the vent pipe I would see water running down the outside of the vent pipe, which is visible (inside a cabinet) at the point where it goes through the floor and in to the tank.
Further puzzling things: I was able to block the AC return duct on either side of the where the vent pipe enters the roof. The think being that I could isolate the section of the AC ducts that are close to the vent stack.
So I can't be sure at what point along the ductwork the smell is being drawn in and I really can tell from what point the tank is leaking. It has to be somewhere in the ceiling because the smell isn't present at any of the drains or admittance valves.
I'd replace the pipe at this point except that the location where the pipe meets the tank is right under a major wall.
Perhaps I can cut the pipe at the point where I can see it under the cabinet and then resection it from there. Or insert a smaller pipe inside the bigger one.
Like I said, it's a puzzler.
Also: the tank has been cleaned and cleaned and cleaned. Bleach, Fabuloso, Oxy-Clean, baking soda, etc etc. It's as clean as it's ever going to get.
