Quick overview

  • Sta-Rite part 24800-0121 The air bleed assembly listed for the System 2 Modular Media PLM filters.
  • Purges trapped air Opening the bleed lets air out of the tank so the filter fills with water instead of running on an air pocket.
  • Common leak point The bleeder sits at the highest point on the tank, so a cracked body or a tired seal shows up as a drip or a spray whenever the pump runs.
  • Complete assembly Supplied as the assembly rather than a loose stem, so you are not matching small pieces.
  • Also listed for Aquatools The same assembly appears under Aquatools permanent media and DE filter parts.
  • Do it with the pump off Never open a bleed valve on a pressurized tank; shut the pump down and relieve pressure first.

Product details

The Sta-Rite 24800-0121 is the air bleed assembly for System 2 Modular Media PLM series cartridge filters. It is the manual air relief that sits on top of the filter tank.

What it does

Air collects at the top of a filter tank every time the system is opened or the water level drops. Trapped air stops the tank filling properly and makes the pressure gauge read badly, so the bleeder gives you a way to let it out until water comes through. Because it lives at the highest point of a pressurized vessel, it is also the piece that shows its age first: a cracked body or a worn seal turns up as a drip or a thin spray whenever the pump runs.

Fitment

The assembly is listed for the System 2 Modular Media PLM100 and PLM150, and it appears on the wider System 2 diagram that covers PLM 100 through 300. It is also listed under Aquatools permanent media AT84100 and AT84150 and DE AT8230 to AT8236 filter parts. Match it to your parts diagram before ordering.

Always shut the pump down and let the tank pressure fall before working on the bleeder or the clamp.

Questions and answers

What people ask about this product, answered by our pool techs.

Which filters does this air bleed fit?
It is listed for the Sta-Rite System 2 Modular Media PLM100 and PLM150. The wider System 2 parts diagram covers PLM 100, 125, 150, 175, 200 and 300, so check your model against the diagram before ordering.
Is this the same part used on Aquatools filters?
It is also listed under Aquatools permanent media AT84100 and AT84150 and DE AT8230 to AT8236 filter parts.
Why is my bleeder leaking?
The bleed assembly sits at the top of the tank under full system pressure. Age, sun and over tightening crack the body or flatten the seal, and the result is a drip or a fine spray while the pump runs.
Can I open the bleeder with the pump running?
No. Shut the pump off and let the tank pressure drop before you touch the bleed valve or the clamp.
