COMPATIBILITY
System Requirements
The Autotrol 1000211 #9 Backwash Assembly is designed specifically for Autotrol control valves installed on 9-inch diameter mineral tanks. This assembly regulates drain flow during the backwash cycle and is compatible with residential water softeners, iron filters, and media filtration systems using Autotrol valve heads. Note that the backwash ball (part #1030502) must be ordered separately and is required for complete assembly function.
🔧 Pro Tip: Always inspect the backwash ball seat for debris or wear when replacing the assembly. Even minor obstructions can cause incomplete backwash cycles and reduce media effectiveness over time.
