The Pentair 98209800 High-Flow Manual Air Relief Valve is a genuine OEM replacement assembly designed for compatible Pentair pool and spa filters. Installed at the top of the filter tank, this valve allows trapped air to be safely released from the filtration system during startup, priming, and routine maintenance.Air can accumulate inside a pool filter after the pump has been turned off, the filter has been opened, or the plumbing system has lost prime.

This replacement assembly is commonly used when the original valve is cracked, leaking, difficult to operate, clogged, or no longer sealing correctly.Part 98209800 is compatible with many Pentair cartridge and D.E. filters, including select Clean & Clear, Clean & Clear Plus, FNS Plus, Quad D.E., EasyClean, Predator, Warrior, and 4000 Series models.
