Hi

I have 6 floor returns, all on 1 valve. I am using a large stand up compressor directly into a tapped 1/4" fitting on the return side. I let the compressor completely fill the tank, then let it blow out the line with all other return lines closed. I am seeing a good amount of air bubbles from the 2 returns closest to the filter area in the shallow end, but nothing from the other 4. Is this normal, or do I not have enough flow and need another method?

Thanks!
 
What happens when you plug the 2 returns you get bubbles from? You get any bubbles out of the other returns?
 
It’s not a floor cleaning system, just returns. They don’t have any mechanism to “pop up”. I asked my PB, they said it is “ probably fine” as long as the 3 ft off line from the filter to to underground are blown out.
 
If it’s just returns then I again say be patient, the water will be blown from them. I have numerous pools with 4-6 returns, duck plug them all and after 10-20 minutes on my big blue blower they are all bubbling like crazy.
