In addition to the above, the following should be considered when deciding upon whether or not to use an air gap in your particular installation:
- In a continuous piping system, each air gap would require the added expense of reservoirs or tanks and perhaps the installation of a secondary pumping system.
- The air gap may be easily defeated if the proper gap isn't maintained, thus negating backflow protection.
- At an air gap, the water is exposed to the surrounding air with its inherent airborne pollutants or contaminants and thus may no longer be potable.
- For these and other reasons, air gaps must be inspected frequently to assure that they are providing adequate backflow protection.
