is this an automatic air relief valve

Hello, This is not an automatic air relief valve.

I received the air relief assembly but there is not a thumb screw for one of the holes. Is this supposed to go on the DE filter likes it is or is a piece missing? The thumb screw broke off the old part.

A  Answered on 9/28/2016 by InyoPools Product Specialist Alan M.

Hello Arleen, this air relief valve includes one thumb screw. What is not included is a pressure gauge that would be inserted into the second hole like the Gauge Press w/ Indicator Rear Mount.

I need the part in the small picture that shows the thumb shut off. Does the part 9239-02 come with that ?

A  Answered on 6/1/2016 by InyoPools Product Specialist Alan M.

Hello, Yes the Air Relief Assembly does come with the thumb screw that controls the release of air from the filter.

We just bought a house with a hot tub in it and the system is a sta rite posiflow stainless filter and pump. The air relief assembly continues to drip, is there an o ring inside that needs to be replaced?

A  Answered on 8/27/2015 by InyoPools Product Specialist Lennox H.

Hi Scott, You would have to replace the entire Air Relief Assembly, there isn't a replacement part # for the o-ring located inside of this assembly.
