I'm convinced I've gone backward from where I was last year with flow and leaks and such, but am in the midst of trying to "diagnose" the current issues. What I noticed was that when I have the pump on its "normal" setting (2200 RPM) there is a stead stream of small bubbles coming out of one of the jets (the one that almost comes straight out from the wall - I didn't really look at the other one, which comes out almost parallel to the wall).
While this is new this year, what I found kind of interesting is that if I cranked the pump way up (3400 RPM in this instance), the air bubbles completely go away.
What I was wondering is if, at the lower setting, there's room for a little air to get in somewhere on the suction side while, at the higher setting, there's so much water flowing so fast that there's no room for air.
Does that make any kind of sense at all? Is this an indicator of anything or just common place?
