This drain fitting supports Sta-Rite System 3 21 inch and 25 inch filter models that require a reliable drain connection for service.

Drain fittings are central to clean, controlled water removal during cartridge cleaning, pressure relief, and seasonal shutdown. A damaged fitting can lead to leaks or make filter maintenance more frustrating than it needs to be.

  • Compatible with select 21 inch and 25 inch System 3 filters
  • Provides a serviceable drain connection
  • Helps support cleaner maintenance and winterizing procedures

Replace the fitting if threads are worn, the body is cracked, or the drain connection no longer seals consistently.
