To prevent backflow, which of the following should be created?

1. A cross-connection
2. An air-gap between the faucet and the flood rim of the sink
3. A physical link between the potable and contaminated water supply
4. Multiple sources of water

Answer :

Final answer:

To prevent backflow, an air-gap between the faucet and the flood rim of the sink should be created. This physical gap acts as a barrier, preventing any contaminated water from flowing back into the potable water supply, ensuring no cross-connection between the two.

Explanation:

To prevent backflow, an air-gap between the faucet and the flood rim of the sink should be created. This is a physical gap that prevents any contaminated water from flowing back into the potable water supply. It acts as a barrier to ensure that there is no cross-connection between the potable and contaminated water supply, thus preventing the risk of contamination. The air-gap allows air to enter the system, creating a break in the water flow and preventing any potential backflow of contaminants from the sink to the faucet.
