Cleaning Hunter Valves: Step-by-Step Field Procedure

User knows where valve boxes are (two green boxes) but asks how to actually clean the valves.

Procedure

1. Dig around boxes until hole is deeper than valves/pipe. Expect multiple valves per box. Don't cut wires.
2. Take a photo before disassembly for reassembly reference.
3. Identify problem valve: run that zone from controller; feel/hear solenoid buzz.
4. Shut off water supply.
5. Remove valve top screws.
6. Inspect for debris; remove any found.
7. If not obvious, crack water supply briefly to flush—just a little to avoid filling hole with mud.
8. Reassemble, turn water on, test.

Matt emphasizes having a helper to watch valves while flushing. This is the standard field cleaning method for debris-related valve failures.
