I have a single bubbler on my baja ledge. The water is 6” deep. The bubbler randomly goes into this spinning flailing mode where the water splashes all around. It will randomly just go back to normal. Builder has tried 3 different “eyes” on the end of the pipe, and all do the same. They are basically giving up and saying they can’t fix it. Does anyone have any ideas? The bubbler is split off the output of the main pump which is a Jandy 2.7 variable speed. I have one valve for the bubbler, one for the pool returns and one for the spa return. I’ve tried changing the valves as well as varying the speed of the pump. Any ideas?
