Pentair Clean & Clear High Flow Manual Air Relief Valve with Gauge (98209800)

Pentair Clean & Clear High Flow Manual Air Relief Valve with Gauge (98209800)

Air trapped in a cartridge filter reduces flow, causes noisy operation, and can prevent the system from priming correctly. The Pentair Clean & Clear High Flow Manual Air Relief Valve (Part 98209800) releases trapped air quickly and safely, with an integrated pressure gauge so you can monitor filter pressure at the same time.

A genuine OEM replacement for Pentair Clean & Clear cartridge filter systems.

Key Features

• High flow air release — rapidly purges trapped air from the filter housing
• Integrated pressure gauge — monitor filter pressure without a separate gauge fitting
• Manual operation — simple twist-to-release design, no tools required
• Genuine Pentair OEM part — exact fit for Clean & Clear cartridge filters
• Durable black PVC body — chemical and UV resistant for outdoor filter installations

Frequently Asked Questions

How do I know if my air relief valve needs replacing?
Signs of a faulty air relief valve include air constantly escaping during normal operation, inability to build filter pressure, water leaking from the valve body, or a cracked/damaged valve housing. If the valve won't seat properly after releasing air, it should be replaced.

Which Pentair filters does part 98209800 suit?
This valve is designed for Pentair Clean & Clear cartridge filter systems. Always verify your filter model and existing part number before ordering to confirm compatibility.

Does this include the pressure gauge?
Yes — the pressure gauge is integrated into the valve assembly as shown in the product image. No additional gauge fitting is required.

How do I bleed air from my cartridge filter?
With the pump running, slowly turn the air relief valve anti-clockwise until air begins to escape. Once a steady stream of water (not air) flows from the valve, tighten it clockwise to close. Check the pressure gauge reading — normal operating pressure is typically 50–70 kPa depending on your system.
