We are remodeling our kitchen and discovered that the drain line has an air admittance valve. Being in such close proximity to a vented drain pipe from the grey tank, is the air admittance valve necessary? Eliminating it would make for a cleaner installation of the new cabinets.
NOTE: In the picture, the sink is on the left. After the remodel, the sink will be about 18" closer to the vent stack.
