Facilities, Cleaning & PestsQuestion 302 of 320

A hose bibb (outdoor faucet) is used to attach a hose for cleaning. What device is commonly installed to prevent backflow at that connection?

a.A pressure gauge
b.A grease trap
c.A floor drain
d.A vacuum breaker (backflow prevention device)

Explanation

A hose connection is a common backflow risk, so an approved backflow prevention device such as a vacuum breaker is installed to stop contaminated water from being siphoned back into the potable system. When a permanent air gap is not feasible, a mechanical device like a vacuum breaker is the accepted protection. Grease traps and drains serve entirely different plumbing functions.
