Product details

The Pentair 98209803 is the manual air relief valve assembly used on the 2000 Series, 4000 Series and FNS Plus filters. It is the genuine Pentair part, supplied as the complete assembly.

What it does

This is the small valve on top of the filter tank that you open to bleed trapped air after cleaning the filter or restarting the pump. Air left in the tank makes the gauge read wrong, cuts flow, and in a pressurised tank it is what makes a lid dangerous to open.

When to replace it

Two symptoms send people to this part. The valve weeps water constantly and leaves the tank top wet, or the valve seizes and will not open or close cleanly. In both cases the internal seal and stem have worn, and the assembly is replaced as a unit. Always shut the pump down and release all tank pressure before touching it.

Questions and answers

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

Which filters does this fit?
The Pentair 2000 Series, 4000 Series and FNS Plus filters.
Is this the whole valve or just a seal?
It is the complete manual air relief assembly.
Why is my air relief valve leaking?
The seal inside hardens and the stem wears, so the valve no longer closes tight. Once that happens the assembly is replaced rather than repaired.
Do I need to shut the pump off to change it?
Yes. Shut the pump down and release all pressure from the filter tank before removing anything on top of it.
