Hi all, hope you are all healthy and holding up well during these times. Opened pool today, I hear what I can best describe as a sucking sound near my mult-port valve. Does it intermittently, don't see any bubbles in pump basket or coming out of jets really. What's the best way to diagnose what this issue is for sure?
