Question

A _____ inch air gap between a faucet spout and the flood rim of its fixture to prevent a possible cross connection:

Answer 1

An air gap is necessary between a faucet spout and the flood rim to prevent cross-connection and protect the drinking water supply.

Step-by-step explanation:

An air gap is required between a faucet spout and the flood rim of its fixture to prevent possible cross-connection. This is to ensure that contaminated water does not enter the drinking water supply. The air gap acts as a physical barrier that prevents backflow.

For example, if there is no air gap and the faucet spout is submerged in dirty water, there is a risk of contaminants such as bacteria, chemicals, or other pollutants flowing back into the water system.
