Howdy everyone! I am unable to find any manual for the filter for my pool and have a question that I hope someone has the answer to. In the diagram I attached, part #7 is described as "air relief assembly w/ tube" on the parts site I found. I am not sure how this works. It pokes up above the top of the filter cartridges and then of course there is the pressure gauge and relief valve up above it. With my layman's eye it seems they should connect together somehow but mine do not seem to do that though the pressure valve seems to do it job when I open it. Also #1I in the diagram is described as a plunger, which appears to be missing in my assembly.
Is that tube supposed to attach to the gauge/valve assembly when I put the lid back on? If so, would it not being connected cause my pressure gauge to always read the same pressure? In my case, 18 PSI, no matter how long I let it go between filter cleaning.
Just taking a shot in the dark hoping someone has some knowledge of this product before I go off ordering parts I may or may not need.
