Hi all. My Jandy CS250 filter pressure reading has dropped a lot recently, and much more water is flowing. I assume this means the cartridge is damaged, probably torn.

That makes sense since I've been pressure washing it for the past year, knowing I'd need a new one soon anyway so not minding if I broke it (I've had the pool 3 year, and I've no idea how old the filter was when I got it).

Anyone know a wallet friendly replacement for this cartridge that is going to fit well and still do a good job? I'm seeing replacements anywhere from $100 to $500 which is a heck of a difference
 
Unicel, Pleatco, and Filbur are all large and reliable suppliers of filter cartridges. Always compare dimensions of existing cartridges or manual to any filter you are considering buying.

Every reputable brand of filter-cartridge manufacturer will tell you, "NEVER use a pressure washer." That is the #1 way to destroy the fabric and likely tear a hole somewhere among all those pleats.

I get that it's risky but the only reason I did it was that I knew I was due for a new one anyway so didn't have much to lose. And it did get it significantly cleaner for a year before this happened. For the new one maybe I'll invest in one of those comb type hose attachments
