We have our sink in the peninsula with the vent running through a half wall to the exterior wall where the vent stack is. The house was built in 2003. It is not code right now (6" above flood level of sink) because the vent is 34.5" from the floor and my current top mount sink is 37".
We want to move the half wall with plumbing out 8" and have a level countertop. We are on a concrete slab with tension cables and the waste drain is in the slab, so we cannot move the location of the kitchen sink, cannot move the waste drain, and cannot do an island loop vent (because I don't want the very expensive cost of breaking up the concrete slab). Studor vents are also not allowed.
Do I have any other options in order to have a level counter? Or am I stuck with a 2-tier counter in order to have the vent be 6" above the flood level of the sink? A plumber proposed doing a dirty arm, but I can't find much about them online, or if they are code for kitchen sinks. Everyone keeps saying island loop vent or Studor, both of which are not options for me.
I tried to attach photos, but kept getting error messages.
