A hose is connected to a faucet and left submerged in a mop bucket of dirty water. What hazard does this create?
a.An improvement to water conservation
b.A cross-connection that could allow backflow of contaminated water into the potable supply
c.A minor cosmetic issue with no health impact
d.Nothing, because the water pressure only flows out
Giải thích
A hose submerged in dirty water creates a cross-connection: if pressure drops, back-siphonage can pull the contaminated water into the potable plumbing. This is exactly the scenario backflow prevention devices and air gaps are meant to stop. Hoses should never be left in standing water, and a backflow preventer or air gap should protect the connection.
