Sudden Low Pressure on One Station – Break, Blockage, or Valve Issue

Station 4 loses pressure suddenly. Other stations fine.

Troubleshooting Order

1. Walk zone: look for geyser, wet spot, or sunken head (break).
2. Check valve flow control: cycle open/closed several times to clear debris.
3. If no break, shut off water; disassemble valve bonnet; inspect for rocks, debris, diaphragm tear.

Sudden onset suggests physical obstruction or break, not gradual wear.
