I'm back again in need of some help. I recently noticed bubbles in my pump strainer basket. I'm not sure how long it has been since this happened, but it was within the last few days since I had not noticed them before.
The issue seems to be coming from the deep end skimmer. I have two skimmers, one deep end and one shallow, and I have the ability to isolate them. When I close the valve on the deep end skimmer all of the bubbles disappear. They appear again when I open it back up.
The bubbles are small and I am not losing prime. There are no bubbles coming out of the return jets. Everything seems to be functioning "OK", but I'm worried.
Some additional information - this same skimmer that is now having issues was blocked temporarily the other day. A large frog had gotten sucked into the line when I removed the basket to hook up the vacuum. He must have been hiding where the weir is, because when I took off the lid and removed the skimmer basket he appeared in the water and immediately got sucked into the line. I had already isolated that skimmer to give me greater suction when I attach the vacuum. I ran over to the pump and noticed the water in the basket had dropped and was frothing and the pump got louder.
I went to go turn off the pump but then I noticed that the basket started to fill back up with water and resume its normal function. When I looked in the basket I saw the poor guy in the basket. A total of probably 45 seconds elapsed between the line being blocked and the line clearing.
Did I screw something up? Where do I go from here?
