Recently got my first hot tub and have came to find out I filled up the tub wrong. Dont really know too much about hot tubs. It is a two pump system one pump is running great the other is not. I have bleed out air from the system with no results. If I run what is working and turn the valve on top of the filter cap air still comes out. Do I need to keep letting air out or what should I do next. Please help I have looked on here for hours trying to find something to help me out.
