Backflow Prevention in Johnson County, Indiana
A backflow preventer is a valve that stops used or dirty water from flowing backward into your clean drinking water line. Indiana requires every backflow device to be tested when it's installed and at least once a year after that (327 IAC 8-10-8). I install, repair and replace backflow preventers for irrigation systems, homes and businesses across Johnson County.

Backflow, Explained
What Is a Backflow Preventer?
A one-way valve assembly on your water line. If water pressure drops, it keeps water from your sprinkler system, boiler or business equipment from being pulled back into the drinking water supply.
Do I Need One?
If you have an in-ground sprinkler system, you almost certainly do, and so do many businesses. Your water utility decides which properties need one. If they sent you a letter, that's your answer.
How Often Does a Backflow Need to Be Tested in Indiana?
At installation, then at least once every year. Indiana's rule (327 IAC 8-10-8) says each device must be inspected by a registered cross-connection control device inspector at intervals not exceeding one year.
Who Is Allowed to Test a Backflow in Indiana?
Only a registered cross-connection control device inspector. Indiana requires 40 hours of training plus written and oral exams to register (327 IAC 8-10-11).
What Happens If My Backflow Fails Its Test?
It needs to be repaired or replaced and tested again. Your utility sets the deadline, so check the letter they sent. I handle the repair or replacement.
Do I Need to Test My Sprinkler Backflow If I Don't Use the Sprinklers?
Usually yes, as long as the system is still connected to the water supply. Some utilities, such as Citizens Energy in Indianapolis, say an unused irrigation system still needs its annual test unless it's properly disconnected. Check with your utility.
