Is My Filter (Hayward DE) not working?

If something much larger than a few microns is getting through your filter and coming out the other side, you've definitely got a problem with it. You could probably open the filter and physically examine them to find out for sure.


Just a thought, but you haven't inadvertently set it to bypass or anything like that, have you?

I used to think that when I backwashed, some of those palm seeds(needles) might have gone inside the grids and they are coming out, but its been more than a week since I started observing this. So doesnt seem like that.

About the valves, I am not that sure if I am doing something wrong there. I have attached a picture of our setup.
As much as I could see there doesnt seem like a bypass where it bypasses the filter, correct? This is exactly how the valves are set now.
One thing is on the returns I can see that there are 4 pipes going out,
1. to return 2. to water feature 3. to pop-up cleaner . I dont know if the 4th one is going to the heater? So what happens if I close that one?

Appreciate your time.
