I recently had my pool re-plastered and I also had my DE filtration replaced with a Jandy 580 cartridge system. My previous home I had an inground 15,000 gal gunite pool with a Sta-Rite System 3 cartridge filter system. I chose a Jandy over the Sta-Rite due to having a small equipment pad and it was a better fit. However, on initial start up there was a leak from the tank due to a factory damaged O-Ring (note photo). Also, upon removal of the clamp rod, a piece broke off (see photo). Other than that, cleaning the Jandy is a tad easier as the filters are smaller however, the cartridge pleats are more difficult to separate for cleaning than the Sta-Rite. Anyway, I hope this is not a sign of Jandy craftsmanship as it's too late to turn back now. If nothing else goes wrong I will be happy with the Jandy but I never had a problem with the Sta-Rite and I just wanted to share this experience with you all.
