How do I know if my system requires an air gap faucet?

A standard faucet will have a single tube attaching to the underside of the faucet, where as an air-gap faucet have three tubes attached to its underside.

What does “air-gap” mean?
The term air-gap refers to the "gap" in the drain line of an RO system to prevent back-flow from your household sewage line into your RO system. The drain water flows out of your reverse osmosis system into one tube of the air-gap, passes over the gap, and then down the other tube into the sink drain piping. Some dishwashers also use an air-gap, but they use a much larger line than a RO system. 
Air gap faucets can be used with both airgap and non-airgap RO systems. Non-airgap faucets can only be used with non-airgap systems. If your building code calls for an airgap, but you prefer one of the non-air-gap faucets, then you may use an external air-gap that fits around the RO faucet, or a combination dishwasher and RO system air-gap.

Air-gap faucets reduce the amount of sewage backflow that can back up into your RO system.

They can be noisy and gurgle. They sometimes back up all over your counter top.

The Home Master advanced reverse osmosis system uses a one-way valve on the drain line which prevents sewage backup into the system. It also allows you to choose from a wider variety of RO faucets.
