Backflow protection has been an issue ever since potable water and hazardous water have been “cross-connected” (i.e. tied together). Irrigation water has been deemed a high hazardous use of potable water and consequently requires a relatively high degree of protection. Sprinkler systems supplied by dedicated wells or irrigation water need not be protected.
In the 70’s and early 80’s it was determined that spring loaded backflow assemblies on sprinkler systems were necessary for adequate protection when exposed to water pressure for over 12 hours. These stainless steel springs were deemed necessary to break the tensional “seal” that occurs between the brass (or plastic) body of the backflow assemblies and the rubber parts of the check, air inlet and relief valves of these devices when under constant pressure. Test cocks were added to most of the devices to aid in the determination of their integrity by allowing them to be tested. To conform to the Federal Clean Water Act of 1972, states and many municipalities have passed codes that require the implementation of these backflow assemblies as well as their various testing requirements.
Keeping sprinkler system backflow devices in good working order is paramount in keeping our drinking water safe from possible contaminants. These include pet and wildlife excrement (including goose poop), as well as fur. It is necessary to maintain the integrity of the backflow assemblies, and illustrates the need for the periodic testing of these devices.
To assist its customers reduce the risk of possible contamination of the public water supply, Alpenglow Sprinkler has a certified backflow tester on hand. In addition, most of our trucks are equipped with the parts necessary to repair these devices, if necessary, in order to keep them in good working order. Please don’t hesitate to reach out and ask for our assistance in keeping your backflow device compliant with federal, state and local requirements.
