What are the steps to change a cartridge filter on a pool already running. I used an old (clean) filter for start up and slamming but would like to change it and put in a new filter. I can’t remember the steps to change the filter. I think it goes like this: First turn off system, then close the ball valve on the pump. Then open air release screw on top of lid of filter cartridge tank and open drain on bottom of filter cartridge tank and let water drain out then close drain plug. Then open lid of filter cartridge tank and pull out filter. Put in new filter, put on filter cartridge tank lid, open ball valve to let water back in filter cartridge tank, turn on system, bleed/open air release screw till water squirts out then close. Reprime if necessary by opening pump basket lid then close when full, rebleed air release screw.
Did I miss anything, are steps correct and do I have to drain the water out of the filter cartridge tank???

You might keep some pool silicone lube handy just in case there's a large O-ring around that filter that seals the upper & lower halves together. I sometimes have to add some fresh lube to mine.
I can get it back off and on again. Where would the pool lube go? There seems to be two pieces to the tank lid (an inner lid and outer ring). Do they come apart? Is there an o-ring that goes between them? I couldn’t see one. I did put Teflon tape on the threads hoping that would help. Now I am hoping that was not a mistake
My fear is having the lid explode!!!!
