I have a Polaris 280 that recently stopped moving. The booster pump is working fine. I checked the filter screen and found it quite dirty and even split. I replaced that as well as the backup valve and no change. Next move was to replace the pressure valve, still no change. While I had the cleaner out of the water and the pressure valve removed I tried blowing through the hose and was able to move air through the hose and out of the cleaner so I assumed there is no clogs down line from the reverse valve. Suggestions?
