Just installed 4 new cartridges in my Hayward C3025 and after putting everything back together, I noticed two things:
1) The pump strainer basket is not completely filled with water. It's probably a good 2-3 inches from the top and the splashes aren't even touching the top of the lid
2) The pressure is reading between 2 and 3 psi.
The return lines have a pretty good flow of water coming out (more than when the old cartridges were in there).
Is this normal or is something else going on? Thank you.
