Mystery big bubbles

Hi,

Ocassionally on my friends pool large air bubbles come from one of the returns. It's a newer 10k pool with 100 sq ft single catridge filter and a Hayward VS pump. The weir door is not sticking on the skimmer and the pump doesn't appear to be losing prime. It happens rarely and only for a short time.

I service another pool where it happens with the single bubbler on the shelf. The fountain goes high and then drops off. I would be interested in getting some thoughts on what it...
