How are you measuring your pressure? Are you using some type of a pressure tester as noted in the troubleshooting, or are you observing what is on the guage of your filter?

The reason I ask is I had an issue with mine last summer, and it drove me nuts trying to figure out what was wrong. My filter guage constantly read 15 psi and everything seemed to work, except my Polaris would not work and the Randomizer tube was not moving, as yours is not.

I finally determined that I had a hairline crack in my leaf pot lid and it was letting enough air in to reduce pressure. Why the filter guage didn't register any difference, I don't know. I certainly don't think that my pressure dropped at or below the 5 psi that the manual indicates is necessary for it to work. Yet, when I bought a new lid, the Polaris immediately started working - no problem since.

Do you know anyone else with one (Polaris), that you can borrow to eliminate it as the problem?

I just don't believe that yours is the problem though - since it is new. IT seems more likely that you might have something similar to what I had. However check the entire chamber assembly for cracks which would lead to pressure leaks.

Just fyi, I and my neighbor have had all kinds off issues to cause these Polaris 65s not to work:

- Filter screen (#34) clogged
- Randomizer tube screen (#9) clogged
- Chamber connector cracked (#10) causing pressure leak
- Piston assembly (#5) worn out so that it didn't seat against the cylinder very tightly (there are a couple of plastic rings that go around the piston - we bent these out to get a better seating - and the Polaris then worked like new)

Those were mostly covered by the troubleshooting, which you went through without problems, and you shouldn't have had these problems anyway since your unit is new.

I hope something in this might give you a clue in solving your problem ...
