An irrigation backflow preventer can leak because of freeze damage, worn or damaged internal components, debris, pressure conditions or problems around the irrigation supply assembly. The location and timing of the leak help determine what needs repair.
Freeze damage
Above-ground irrigation components are especially exposed during cold weather. Water trapped inside can expand when it freezes and damage housings, fittings or internal parts.
Debris and internal wear
Debris or worn components can prevent internal parts from sealing correctly. A technician can inspect the assembly and surrounding irrigation supply to determine whether repair is practical.
Repair versus testing
Fort Mill Irrigation provides backflow and irrigation-supply repair related to residential sprinkler systems. We do not advertise backflow certification testing.
Winter protection
Our sprinkler winterization service is intended to reduce trapped water in irrigation components before freezing conditions.
