Overland Park, KS: what's different here
Overland Park sits in Johnson County, Kansas, about 12 miles and roughly 16 minutes by car from Kansas City via the main highway. The city's median age is 38.6 years, pointing to a mature suburban housing stock rather than a newly built city. Older irrigation and plumbing systems often mean backflow devices that need annual testing. A local pro from the Kansas City area can easily serve Overland Park homes.
How often is backflow preventer testing required in Kansas?
Kansas ordinance materials say testing intervals shall not exceed 1 year. KC Water also requires annual operational testing of backflow devices to protect the public drinking water supply. Certified tester-repair technicians must be re-certified at intervals of no less than 3 years.
What does a certified backflow tester need?
A Johnson County community college certification course requires at least 5 years of experience in plumbing, mechanical, fire sprinkler, lawn irrigation, or a related potable-water field. The course runs 40 contact hours and lists tuition of $749.00 for one session. Any tester certified in Kansas may be used as long as their current certification is on file with the city.
What happens if I miss the backflow test deadline?
KC Water says a Missouri state certified tester must submit the inspection report online within 7 days of water being turned back on. If the test is not submitted, service will be disconnected again with an additional $75 restoration fee. In Lawrence, each backflow test entry costs $9.95 payable directly to Aqua Backflow.
Do irrigation systems in Overland Park need a backflow preventer?
Prairie Village's irrigation code says potable water to lawn irrigation systems must be protected by an atmospheric vacuum breaker, pressure vacuum breaker assembly, or a reduced pressure principle backflow preventer assembly. Similar rules apply across Johnson County communities. Installing or replacing a device may require a Cross Connection/Backflow Permit, as the City of Olathe requires.
What to do next
- Confirm your device type - atmospheric vacuum breaker, pressure vacuum breaker, or reduced pressure principle assembly - before booking the annual test.
- Ask the pro for proof of current backflow tester certification; Kansas and Missouri require recertification every 3 years.
- Check whether your city requires a Cross Connection/Backflow Permit before installing or replacing a device.
- Get a written quote listing the per-assembly test fee, since most tests run $50-$250.
