Recycled Water Zone Pressure Fluctuation: Valve Adjustment and Cleaning

Zone 2 Pressure Issues on Recycled Water System

Florida system on recycled water (city-scheduled supply hours). Zone 2: intermittent dribble then full force, now consistent dribble. Other zones fine. Controller shows normal operation.

Recycled Water Considerations

Recycled water often carries higher sediment/organic loads, accelerating valve diaphragm fouling and port clogging.

Systematic Fix

1. Adjust valve flow control: Open fully → close fully (count turns) → reopen halfway
2. If no improvement: Disassemble valve — clean all ports, inspect diaphragm for tears/punctures, replace if damaged
3. Check for debris in solenoid ports — tiny passages easily clogged
4. Install filter upstream — 150-mesh screen filter on mainline protects all valves

Scheduling Constraint

Work within city water windows. If problem persists after cleaning, schedule professional service during next available water window.
