We have a 2004 series 7000 Cal Spa. This seems like an odd question concerning the volcano jet on the bottom of the spa. The jet does not turn to control water flow like the others in the spa but moves up and down. We don't know which position (up or down) slows the water flow down. We have tried different postions but it doesn't seem to make much difference. What position should it be in to slow down or turn off the water flow? We would rather have the small jets that surround the large volcano jet on which is my next question. They are all turned on but the water flow is very low. How can we increase the flow from those small jets.
