One of the state mandated requirements of having an irrigation system is protecting the potable water supply with an approved and testable backflow preventer. This requirement is listed under the Ohio EPA and the Department of Commerce. This backflow preventer must be tested every year.
We test residential and commercial devices with pricing that does vary based on the application and size of the backflow device. Backflow prevention assemblies are to be tested and the results reported in accordance to each specific local utility or water provider. Any part of the check valve, relief valve or air inlet valve found defective must be repaired or replaced immediately, and a retest must show the assembly is operating properly. Leaking shutoff valves which prevent a test from being made must be repaired.
