Pentair 24800-0121 Air-Bleed Assembly — Replacement for PLM Filter Systems
The Pentair 24800-0121 is an OEM air-bleed assembly designed for use with Sta-Rite / Pentair System:2 (PLM) series sand filters. This small but essential component helps purge trapped air from the filter tank when filling or priming the system — ensuring proper water flow and preventing air-lock issues.
Key Features
- Original-equipment air-bleed assembly — exact fit for PLM filter tanks (PLM100, PLM125, PLM150, PLM175, PLM200, PLM300, etc.).
- Allows air to escape during filling/priming, preventing air pockets that can disrupt filtration flow or cause pump cavitation.
- Compact, lightweight part — installs easily without modifying the filter tank or plumbing.
- Durable, pool-rated plastic construction — built to resist pool chemicals and typical operating conditions.
Specifications
- Manufacturer: Pentair / Sta-Rite
- Part Number: 24800-0121
- Application: Air-bleed assembly for PLM-series sand filter tanks
- Compatibility: System:2 (PLM) sand filters — PLM100, PLM125, PLM150, PLM175, PLM200, PLM300, etc.
- Function: Allows trapped air to escape while filling/priming filter tank for safe, efficient operation
When & Why to Replace
Replace the 24800-0121 air-bleed assembly if the original is cracked, missing, or leaking — or if the filter bleeds improperly (air pockets, difficulty priming, uneven flow, or noisy pump operation). Installing a fresh, genuine air-bleed ensures proper priming, efficient water circulation, and prolongs overall filter and pump lifespan.
Installation & Maintenance Tips
- Turn off the pump and relieve all pressure before removing or installing the air-bleed assembly.
- Clean the sealing surfaces on the filter tank before installation to ensure a watertight fit.
- After installation, slowly fill the filter with water — allow air to escape fully before starting the pump.
- Check for leaks or air intrusion during first startup and periodically during routine maintenance.
Why Stock This Part
Because air-bleeds are small, often overlooked components that are vital for proper filter operation, 24800-0121 is a valuable part for pool service professionals and retail customers alike. When it fails, filters may not prime or work properly — so having the correct OEM assembly on hand helps restore proper filtration without replacing the entire tank.
