I have been watching my DE Filter closely lately, because it does not seem to be operating correctly as the pressure rises quickly after I replace the DE.
I have a Hayward 20 Sq Ft Perflex DE Filter which is less than a year old. At first it worked perfectly.
About two weeks ago, I opened it up and cleaned the tubes thoroughly and replaced the DE with exactly 4 pounds as measured by a scale which is what the manufacturer recommends.
However, when I did this, I noticed it was strange that the DE was just sitting at the bottom of the housing, it was not coating the tubes like I had seen in the past.
In any case, I put it back together again added the fresh DE, and ran it again for two weeks and then took it apart today to check the filter and same issue: The DE is just sitting at the bottom. You can see the white fabric of the filter rods as if the DE is doing nothing.
I am not sure what I am doing wrong here.
1. The cloth filters got dirty and now don't pass enough water fast enough for the DE to integrate into the filter? I made sure to run the pump on high (its a VSP) for 6 hours last time I changed it in case this was the issue.
2. Poor quality DE? I got it off of Amazon. It looks like any other DE, but not sure.
What should I do? Should I replace the cloth coverings (Not sure what they are called).
Suggestions appreciated.
