Backflow Equipment and Sprinkler Blowout: Check the Scope

Identify backflow equipment before sprinkler blowout

Photograph a safely visible model label and the surrounding installation. Tell the office whether the assembly is indoors, outdoors or behind a locked door. If the type is unknown, say so. Devices near the water supply can have different purposes and should not be treated as interchangeable.

Ask about separate winter care

Hunter's HC flow-meter winterization guidance warns against passing compressed air through backflow or flow-meter devices. Ask the contractor how that applies to your assembly and service route. Do not copy valve positions from a diagram for another product. Confirm the actual equipment was addressed in the closing notes.

Clarify testing and repairs

Ask whether the visit covers seasonal preparation only or also a separately requested inspection, test or repair. Those are different tasks. Save the model details and work notes together so the next contractor can see what was done and what remains, without guessing from the word winterized.
