I have a Jandy CL460. I took the outer belt off to gain access to the cartridges for cleaning and noticed that the original metal retainer ring had split due to the rivets wearing out (looks like they oxidized or something). I then ordered a new ring and installed it, but now the filter leaks at the beltline when the pump is on. Is there a special way to seat the ring that I need to consider? I'm hoping I don't have to replace the entire bottom part of the filter!!
