An air gap, is the only completely reliable method for preventing backflow.
Backflow is an unintentional reversal of water flow brought on by an abrupt drop in water pressure or a total loss of water pressure. By sucking water back into the public water system where it connects to non-potable water, the decrease in water pressure instead of forcing water out of the plumbing fixture might contaminate the system.
Devices that stop backflow stop contaminated water from entering your supply line from the public water system. Your plumbing will be able to identify contaminating circumstances and stop them from damaging your water supply if you install a backflow prevention device.

A commercial jet liner hits an air pocket and drops 244 feet. After climbing 182 feet, it drops another 100 feet. What is its overall vertical change?
Answer:
-237
Explanation:
Since the jet "drops 244 feet", this means that we start at -244. Since it climbs 197 feet, simply add 197 to -244 to get -244%2B197=-47. So after climbing 197 feet, the plane is still down 47 feet (from it's original height). Since it "drops another 190 feet", just subtract 190 from -47 to get -47-190=-237
