Ok so got my new cartridge today and put it in and my psi went down to 9.....whohoo, so now I want to put in my zodiac and let it do it's 600$+ job. Well I primed it as usual, tried using direct plumb line and skimmer plate line and no go! So then I even changed the tubing to see if the tubing I had maybe had a leak and still no go. Getting loads of suction through it but it won't start popping to actually move itself. Anyone ever had this issue with their zodiac? This thing is very finicky
