Water cannot flow from the sink to the tap in normal circumstances, even if the water supply loses pressure. An air gap, as related to the plumbing trade, is the unobstructed vertical space between the water outlet and the flood level of a fixture. [1]
Backflow prevention device. The simplest, most reliable way to provide backflow prevention is to provide an air gap.An air gap is simply an open vertical space between any device that connects to a plumbing system (like a valve or faucet) and any place where contaminated water can collect or pool.
A check valve, non-return valve, reflux valve, retention valve, foot valve, or one-way valve is a valve that normally allows fluid (liquid or gas) to flow through it in only one direction. [1] Check valves are two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave. There are various ...
Because certain combinations of check valve failure and/or system backpressure cause the relief valve to discharge, the device must be mounted in a location where the drain will not become flooded. An example of where backflow would harm the water supply is the use of well washing devices inside underground sewerage pumping stations.
Vacuum breakers can be used in sewage applications as an alternative to a water seal. It utilizes a one-way membrane that acts similar to a check valve. The membrane is sensitive enough to open under the weight of four ounces of water but remains closed when no water is present above to minimize evaporation and eliminate sewer gas odors. [4]
