Studor mini-vent relocation?
Currently, this is what the plumbing looks like under the kitchen sink. The pipe marked in red goes up to a Studor Mini-Vent that is as far up as it can go behind the left sink basin.
I am wanting to get the counter replaced (granite with undermount sink). The problem is that I donÃ¯Â¿Â½t think there will be enough room back there when I change to an undermount sink. From my calculations, the average dimension of undermount sinks are about 18-20" (external), countertops 24", and the mini-vent is about 3" in diameter. As it is right now, with the topmount sink, there is just enough clearance to unscrew it in case it needs to be replaced. So, I am thinking that I probably want to relocate it. From my initial research, it appears that it is fine as long as it is 4" above the p trap. However, IÃ¯Â¿Â½m confused because some places seem to indicate you want it up as high as possible. It seems whoever installed this wanted it as high above the sink as possible.
