Yes and an air gap for a basin faucet and an air gap located in most dishwasher and washing machines.
The actual size of the air gap is 2 times the effective opening (supply pipe) but in no case less then 1 "

An air gap is to protect the potable water system from contamination from back syphon and it is the best protection possible as there is nothing mechanical to be tested or able to fail (Air gap water distribution) Air break drainage
Lesser air gap, less is the magnetising current (which is lagging reactive component of current)causing better p.f.
water distribution system ===
it bridges the gap between online and off-line content
You don't as it defeats the purpose of the AIR GAP Read your plumbing code

Your air gap is not supposed to leak. Check the hose that leads from the air gap to the garbage disposal for a clog. This should resolve your problem.
The resistance of an air gap is effectively infinite until it reaches its arcover threshold voltage; then it drops to near zero as the air in the gap ionizes. It returns to effectively infinite when the current through the gap is insufficient to keep the air ionized.
Prior to installation; using a feeler guage check the clearence between the armature assemble and rotor at 3 evenly spaced locations. There should be a gap of .060 and .125 (1/8 inch. if the gap is exceeded the armature and rotor should be replaced. With the clutch disengaged, using a feeler guage check the clearence (Air Gap) at both access slots between the ears of the brake flang. This must be between .010 and .015. Tighten or loosen the brake flange mounting nuts to obtain the proper air gap.
Water is non-compressible. The air gap is what allows additional air to be pumped into the rocket.

No benefit, it's required by code. Any food handling equipment must have an indirect waste with an air gap.
This question cannot be answered fully without knowing if the basement is below the grade of the building's sewer run as the installation may involve the use of a sump system. The actual installation is not all that difficult, especially if you are handy with a few tools.
