I have a older hayward cartridge filter and it's becoming nearly impossible to get the retaining strap springy thing ( see pict apologies if that is not the name ) to catch the screw threads when putting the filter back together after some cartridge cleaning. I've lubed it up , but it just never really reaches. Keeps getting worse and worst and seems like there must be a trick or easier way.
Any advice would be really appreciated.
