Is this your test year?
Raleigh's residential irrigation cycle is three years, so your due year depends on when your assembly was last tested. If you've just bought a home with a sprinkler system, ask the seller for the last report or call the Cross Connection team to find your cycle before July 1.

Book a certified tester in spring
You pay for the test; spring booking avoids the June rush.
Repair if needed
Owners must keep the assembly fully operational, so failed parts are replaced and the device retested.
Raleigh summers and irrigation wear
Raleigh lawns are watered hard through hot, humid summers, and three years is a long time for rubber seals to sit under pressure. If your assembly drips, discharges or loses pressure between tests, have it serviced rather than waiting for the July 1 cycle. Our backflow testing page explains how each device type works and fails.
