An example of an Air Gap?

[redwardsjr (Ronald Edwards Jr)]

Just to get an understanding of “Air Gaps”, a lavatory faucet should never be able to dip down low enough to where it can come in contact with the water in the sink? Is this an example?

Air gaps are used in multiple areas of a structures plumbing system(s)…

Note: Don’t confuse an Air Gap with an Air Break!!

Tubs are where you may also see an air gap problem where the faucet is below the rim, especially older ones.
