Sprinkler Warehouse carries the finest in backflow preventers for sprinkler and irrigation systems. Irrigation backflow prevention devices are used to prevent backflow from happening and thus to protect the water supply from contamination and pollution caused by backflow.
Backflow occurs when there is a sudden drop in water pressure inside the irrigation pipes. When that pressure drops, the water can reverse and carry contaminants back to the potable water supply.
These backflow devices can be pressure vacuum breakers, double check assemblies, reduced pressure assemblies, atmospheric vacuum breakers, freeze relief kits, pressure reducing valves, water hammer arrestors, and backflow enclosures, to name just a few. The finest of these backflow preventers are made by FEBCO, Watts, Wilkins and Conbraco.
Double check backflow valve assemblies are the most common devices for inline underground sprinkler systems. They are less likely to suffer frost damage because they are usually installed underground or in a basement. They are also less expensive than reduced pressure zone assemblies. It should be noted, however, that double check valve assemblies are not approved for hazardous substances.
On the other end of the cost and safety spectrum we find the reduced pressure zone assemblies, often considered the industry standard when it comes to commercial property including apartment buildings and condominiums. The provide the highest level of protection against pollutant but they are also the most expensive and complicated backflow devices to install.
According to federal and state laws, backflow devices must be inspected once each year, and they must be inspected and maintained by a licensed backflow testing inspector. In addition, most communities also have their own inspection requirements, so licensed backflow testers must be certified by the state and also licensed by the individual cities.
City Backflow Testing is your go-to company for quality backflow testing, maintenance, inspection and installation. City Backflow Testing tests and services all backflow devices purchased at Sprinkler Warehouse.
It is important to note that the on/off valves included in sprinkler systems are not enough to prevent backflow. These valves can wear out, break or develop leaks, and when that happens, all the chemicals from the irrigation water (pesticides, fertilizers and animal waste) will flow back into the main water supply. Obviously that needs to be avoided at all cost. Thus, the need for backflow preventers.
Depending on the irrigation or sprinkler system you have, several backflow devices may be needed to handle the job and prevent polluting the potable water supply. City Backflow Testing will make sure your irrigation and sprinkler system is functioning safely and properly.
