I will do the tests mentioned in the suction side leak guide, but to me this doesn't make sense. I do have a tiny bit of air in the pump basket but so i know i have a leak (hoping it is just an o-ring repair) that i am going to jump on in a few minutes. My question is why do I only get bubbles coming in on 2 out of six returns? Also, it seems like there are more bubbles coming out the 2 returns than there are in the pump basket. Does any of this make sense?
