Is a backflow preventer necessary when equipment is connected directly to the water supply?

A backflow preventer is necessary when equipment is connected directly to the water supply to ensure the safety of drinking water and prevent contamination. When water flows through piping systems, there is a risk that contaminants from equipment or processes could siphon back into the potable water supply due to backpressure or backsiphonage. A backflow preventer is designed to stop this reverse flow, effectively protecting the integrity of the drinking water system.

This is particularly crucial in food service operations, where sanitary conditions are paramount. Using a backflow preventer helps to comply with health regulations and standards set by public health agencies, which mandate such devices in various situations to safeguard public health. The requirement is not just for drinking water systems but applies broadly to any situation where equipment is linked directly to the water supply. Therefore, since the question states that the equipment is directly connected, a backflow preventer is indeed required to maintain safe water practices.
