Which model number air Relief Manual Valve Assembly (98209800)

A     Answered on 4/11/2017 by Scott W.

What is your filter model?

?     Asked on 10/25/2016 by Richard

I just ordered one of these assemblies tonight from you. My pressure relief valve is leaking at the base where it screws into the filter top. It looks like it has a crack in the relief valve body at the threads. My question is: what is the plastic clamp used for and where does it go? I don't see that clamp anywhere on my filter (Pentair Clean and Clear model 160317).

A     Answered on 10/26/2016 by Alan M.

Hello Richard- The clamp affixes to the small white air bleed sock on the top of the manifold.

Does the Air relief manual valve assembly come with a O-ring ?

Hello Jeff, yes the air relief valve stem o-ring does come with the assembly.

?     Asked on 5/20/2015 by Charlie

My relief valve is dripping. I have a Purex-Triton Filter model #CC100.. Design flow=100 g.p.m. and 6.5 psi residential. There is a pin number on the tank housing =178555..Do I need to purchase the entire relief valve OR the very small "O" rings inside the valve? I have had this unit since 2000. I do not know if this assembly 998209800 is the correct fit But it sure looks like it! Thanks

A     Answered on 5/20/2015 by Patrick P.

Hi Charlie, This would be the correct air relief for the Purex-Triton Clean & Clear CC100 filter. For the CC100 filter I do not show where the small o-ring is sold separately so I would suggest the entire air relief.

?     Asked on 5/15/2015 by fred

where do I get just the two O-rings on the bottom of the relief valve?

A     Answered on 5/15/2015 by Lennox H.

Fred, The o-ring that goes on the bottom of this air relief assembly is P/N 57006800.

Will this valve assembly work on an Aquatec FN/FNS-48 filter?

A     Answered on 4/22/2015 by Andy O.

Jim, This air relief valve part # 4655-03d would be the valve used on FNS PLUS model. If you have the FNS it would be a part # 4600-3550.

Can I install this myself?

A     Answered on 2/16/2015 by Robert M.

The Air Relief Assembly can be installed by a homeowner. It requires that you unthread the old one, wrap some teflon tape around the threads of the new valve, and thread it back into place.

 (3 out of 5 stars)  Replacement for Pentair Pool Filter Relief Valve

from Pleasanton, CA ()

Pros: Quick and easy to install

Cons: Leaks if closed tightly

This is a repalcement the original valve (<4 yrs. old)that eventually began leaking do to a crack at the base where the gauge was threaded. This product was easy to replace, reasonably priced and arrived in a timely manner from INYO. The only problem with this particular valve is that if twisted closed too tightly leaked. I found that you don't need to twist it closed too tightly. Just twist until until it stops (you may need to back off just a little) to ensure it is closed all the way. We will see how long this part lasts.

 (3 out of 5 stars)  Tricky installation


Very tricky to screw on the presure gauge to the relief valve assembly. It kept on screwing on crooked and then leaking a lot after turning on the pump. Only after using a lot of pressure while screwing it on could I get it straight. It still leaks a bit, but will probably stop after a while. I should have returned it. Are they all that way or was this one defective?
