What Frito should’ve said is “ the drain must connect upstream of the vent connection on a loop vent pipes system.
Correct, diagram number one is washed.....see the lavatory above it on the vent ? It’s also a wet vent now.
disagree, if the base vent is rolled, then the base IS being washedWhat Frito should’ve said is “ the drain must connect upstream of the vent connection on a loop vent pipes system.
Having the drain from the sink connect to the horizontal upstream of the vent doesn’t make the vent “ washed “. It’s simply just down stream of the drain connection.
For the vent to be washed it would have to be a wet vent.
If it’s rolled up or laid flat without a fixture attached above it......it’s not washed.disagree, if the base vent is rolled, then the base IS being washed
the intent of the code is for every vent connection to the sewer system or building drain is to be washed by the fixture to which it serves
Yes, that’s why there’s a cleanout in the pipe labeled “ nearest wall “ It’s not washed and if all that backed up it could go into the horizontal snd sludge stay there.Can't seem to find anything about 'washed' vent lines. If I understand what that's referring to is that horizontal runs must be 'washed' - have water run through them. Is this to make sure there's no debris in there?
If that's the case, there are several points in the system of an 'island vent' that are horizontal that are not washed, correct?

I’d do it the way you’re doing itThe main stack (ancient CI pipe) is across the kitchen about 12' away. Other than that, the only vent is the 2" line I'm trying to use. The only other sewer line is the existing line (1 1/2") about 3 feet from where the sink is going. My options are severely limited. I mean, I may have more money than the old lady whose concrete sewer you smashed, but not much more than that. Definitely not enough to reroute my main soil stack.
I could possibly get 3" line in there but that 1 1/2" sewer line would need to be replaced.
