Overall, air gaps are an essential component of plumbing systems, ensuring that the water supply remains safe and free from contamination.
How does an Air Gap Work?
To understand how an air gap works, let’s take a closer look at its structure:
| Components | Function |
|---|---|
| 1. Faucet or Pipe | Serves as the source of freshwater or clean water supply. |
| 2. Air Gap | Creates a physical separation between the faucet or pipe and the sink or plumbing fixture, preventing backflow. |
| 3. Sink or Plumbing Fixture | Receives wastewater or potentially contaminated water. |
| 4. Drain | Provides an outlet for wastewater to flow away from the sink or plumbing fixture. |
When water flows from the faucet or pipe, it is guided into the sink or plumbing fixture by gravity or pressure. The vertical space created by the air gap ensures that there is a physical separation between the water supply and the sink, preventing backflow.
If there is a clog or blockage in the plumbing system, wastewater may start to flow back towards the faucet or pipe. However, the air gap acts as a barrier, preventing the contaminated water from reaching the clean water supply.
The effectiveness of an air gap relies on maintaining the appropriate distance between the faucet or pipe and the sink or plumbing fixture. This distance is usually one inch or more, as specified by plumbing codes and regulations.
By utilizing the unpressurized gap of air, an air gap provides reliable backflow prevention and ensures the safety and purity of the water supply.
