Fleck 500 Air Check, 60002-34 (FL500)

Fleck 500 Air Check FL500

The FL500 is the Fleck 500 air check, part number 60002-34, a component used in air-charged iron and sulfur filters. It manages the air draw and holds the air-water boundary inside the treatment tank, letting the system pull in and retain the pocket of compressed air that oxidizes dissolved contaminants while keeping that air from slipping downstream into the household plumbing.

What It Does For Your Water

In an air-injection filter, the trapped air charge is what turns dissolved iron and hydrogen sulfide into solid particles the media bed can catch. When the air check works correctly, the system maintains its air pocket cycle after cycle and keeps rust staining and rotten-egg odor under control. When it wears out or sticks, you may see the return of orange staining, a sulfur smell, or air spitting from faucets, all signs the air check is no longer sealing as it should.

Service and Compatibility

The air check is a serviceable part inside the control valve, and replacing it is a routine way to restore proper air behavior without overhauling the whole system. It is also a smart item to refresh while you already have the valve apart for maintenance. Because it is model-specific, matching the correct air check to your valve is essential. Because the air check is central to how an air-charged filter treats water, refreshing it is one of the most cost-effective ways to bring an aging system back to life. Water Softener Plus includes the manual with your order and can help you confirm that the FL500 / 60002-34 fits your Fleck 500 valve and application before you buy, so your filter returns to holding its air charge and clearing iron and odor.
