Thanks for the video. I just wanted to add that I had the same problem and was led to this video when researching the cause. The filter under my multiport valve was clean but the video pointed me in the right direction nonetheless. My problem could only have been that the collar was loose and apparently letting air in to the system when backwashing. Put it all back together, snug, and now have constant solid pressure.

That was my problem!! Thank you for posting this video as it's the only one out there I found with this information.

THANK YOU SO MUCH! I called Intex support about this and they were no help at all!

Thanks for the video. My water was so murky and all the clarifier didn't work.. only had the filter a year. Took it apart and so gross. It's working better now.

Turn it on already!!!!!! DAMN

Had the same issue and found out my center pipe was cracked. I left it out over the winter and it froze. Ordered another center pipe and now I'm back in business

Thanks gotta try that on mine

I did all that you did and still having code low flow ? What should I try next ? Thank You

Take off that white screen and throw it away
