I have a Jandy 340 cart filter. The last time i cleaned my filters, inside the case, a large round stainless steel ring came out. the riveted joint broke so it was not a complete circle anymore. This ring looked like it went along the inside of the seam of the top and bottom shell piece. Anyway, i had no way of fixing the band so i reassembled the shell without it. The filter seems to work fine without that piece. The question i have is what is the purpose of that band? Should i get a new one?
I have been looking for stainless steel screws or rivets to fix it and cant find any. thanks.
