Hello all, I am new to plumbing and have an issue with my dishwasher. I have a loop vent system behind my island dishwasher. I was told to cut the vent cap it and install a AAV on the trap side. Is this a good idea? See picture. I am going to run the water line from the side and build another 2x4 frame behind it. Any suggestions about what will work best? I am on a well and septic system. Thanks for all your help and input. Thanks, Jesse
