My pool has a hayward c5025 filter. Two months ago, I bought a brand new set of cartridges. Ran for about a month, I took them out and tried to hose the dirts off, I saw some bands already broken, and there were cracks at the end caps, so water could bypass the filtering and directly enter the inner space. I thought maybe I should have washed more often. Then I bought another new set. It ran for 2 weeks, when I took them out yesterday, all were broken again, even worse than last time!
What could I have done wrong? Maybe I should clean them once a week, or even sooner? My PH stayed around 6.2 for a few weeks, but I don't think it could be the cause. Another thing is the pressure gauge could be off. I did not see the pressure went up, but it did not trigger the alarm on me since I was expecting to clean the carts once every few months!
Any suggestions? I am using this filter for the first time. Any info would be helpful to me.
