Filter pressure going down

[shiyang100]

I noticed my filter pressure has been going down since the pool opening. Average 1 psi every 2 weeks. Since it is not dramatic change, I haven't paid too much attention. But interesting too see where to start for my investigation.

so far I make sure skimmer basket is clean. I also checked the pump impeller and pulled out some pine needles. Anything else should I check?

Thanks.

Did you take apart the pump to clean the impeller?

No, I just used the finger to pull whatever I can pull out.

You might try that.

Wow, I have never tried that before
