Recurring Hunter Valve Weeping: Install a Filter

Chronic Valve Leaks Demand Filtration

Three Hunter valves weeping after cleaning suggests fine debris continuously passing through. Early Hunter valves are sensitive to particulates. Install a VU-Flow T-style screen filter (24–40 mesh) on the mainline upstream of the valves.

Filter Selection & Maintenance

• Use 1½" or 2" body with bushings for less frequent cleaning.
• Manual flush valve dumps 2–3 gallons; install where runoff is acceptable.
• If flushing becomes too frequent, upgrade to an automatic flush valve wired to the last zone.

Avoid cartridge-style filters—they clog faster and cost more to maintain.
