So I am getting rid of my Purex DE filter because I can't buy the part any more. I read conflicting info about the cleaning process of the cartridge elements. The manual and most people say it's simple as just hose down with a garden hose. But there are also people say it's a nightmare to hose it down, soak with chemical and rinse and wait until it dry. So my question is which way is usually done at what point do you need to soak in chemical and how ofter do you do that? Also, why does it have to be dried before reinstall.

And for sand filter owner, how long you do let the backwash process run. Water is expensive in my area.

My goal is to reduce maintenance to the minimum.

Thanks
