I have a spill over (flat, no fountain) and I’m wondering if that’s all that is used to circulate water in the spa. I’ve never seen the spa circulate water unless the jets are on ON and we are chilling. Maybe I just have things placed entirely wrong. Can someone look at the attached pics and let me know where the handles are actually supposed to be to make sure all is working correctly? We just moved in and I know nada about this beauty yet.
