I noticed the top valve was leaking badly when I turned the pump on so I took it off to lube it and clean it and now I can't get the filter to fit into the center pipe. I tried some lube and force and it didn't seem to budge. Any ideas? more pics in link above. Using RX CLEAR filter balls instead of sand.
