How Air Gaps Work

1. Definition of an Air Gap

An air gap is a vertical space, typically twice the diameter of the pipe, between a water outlet and the flood level of a connected fixture. It ensures that backflow cannot occur by maintaining physical separation between the potable water supply and potential sources of contamination.

• Example: The space between a faucet spout and the sink rim prevents dirty sink water from being siphoned back into the clean water supply.

2. Purpose of Air Gaps

Emergency Plumber For Kitchen Sink

Air gaps are designed to prevent backflow, which occurs when water flows in reverse due to:

• Backpressure: Increased pressure in the downstream piping exceeds the pressure in the potable water supply.
• Backsiphonage: Negative pressure in the water supply causes contaminated water to be pulled back into the system.

Importance of Air Gaps

1. Protection Against Contamination

Air gaps provide a simple, reliable way to protect clean water systems from contamination by wastewater, chemicals, or debris.

2. Compliance with Plumbing Codes

Most local and national plumbing codes require air gaps for certain fixtures, such as dishwashers and sink faucets, to ensure water safety.

3. Prevention of Health Hazards
