Olathe, KS: what's different here
Olathe is a city in Johnson County, Kansas, about 22 miles and roughly 26 minutes by car from Kansas City via main highway. The city has 56,011 total housing units and a median age of 38.5 years. The Kansas City area gets about 41 inches of precipitation annually, which keeps irrigation systems and their backflow devices in regular use.
How often is backflow preventer testing required in Olathe?
Olathe requires annual testing of all commercial backflow assemblies. The city also recommends testing after installation, after re-installation, after relocation, and after repairs. Kansas standards say testing intervals should not exceed 1 year, and overhaul intervals should not exceed 5 years.
Who can perform backflow preventer testing in Olathe?
Testing must be done by a certified backflow tester. In Kansas, qualified technicians complete a Kansas Department of Health and Environment approved training course and pass a written examination, such as the American Backflow Prevention Association device testers exam. Kansas and Missouri both require tester recertification every 3 years.
