Identify the backflow protection
An irrigation connection can create a path between landscape water and the public water system.
South Carolina DES describes cross-connection control as a state-mandated program that protects public drinking water (opens in a new tab).
Ask the water provider which protection applies to the property. Record the assembly type, model, serial number, and location.
Follow the testing rule
South Carolina requires assembly testing after installation and annually (opens in a new tab). A water provider's low-hazard residential irrigation policy may set another schedule (opens in a new tab). Confirm the schedule with the water provider.
The public water system keeps the assembly location, type, size, and annual result in its cross-connection control records (opens in a new tab).
Keep the latest result and note the next due date. Ask the water provider where the tester should submit the report.
Use a certified tester
South Carolina DES states that a state-certified tester must complete assembly testing (opens in a new tab).
Confirm the tester's current certification before scheduling the visit. Give the tester clear access to the assembly and irrigation shutoff.
For a reduced pressure principle assembly, keep the relief port above water and away from toxic environments (opens in a new tab). Install it in a pit only when gravity drains the pit to ground surface (opens in a new tab).
Check the assembly before repair
South Carolina DES requires assemblies used in the state to appear on its approved backflow prevention assembly list (opens in a new tab).
Share the make, model, size, orientation, and installation photos with the provider. Ask whether a failed assembly needs repair or replacement.
South Carolina requires immediate testing after every assembly repair (opens in a new tab) under regulation 61-58.7(F)(7)(c).
Prepare an irrigation backflow request
Share the property address, water provider, assembly details, last result, and due date.
Include photos, access notes, visible leaks, and recent irrigation work. Review the irrigation repair guide for other system problems.
