I may give a fish tape a try from the valve side. I've been trying to "snake" from the small motomassage nipple with weedeater trimmer line. Does anyone know if there is a check valve between the valve and the air outlet?

Thank you. I'm sure it's a blockage somewhere between the flow knob and the moto air outlet. Need to figure out the best way to snake.

I'll keep trying to snake through the Moto massage to find the possible blockage. I was curious to know if the clear tubing (with the chase string) is there to let air into the system. Could this be blocked? Sorry for the sideways picture...

Similar situation. dual moto doesn't go up and down. Air tube is collapsing due to vacuum from the jet. First question is... is there a check valve (Hotspring Vanguard) in the air line from the valve to the air "nozzle" in the motomassage? I tried blowing air with a compressor from the motomassage with the control valves removed. It didn't seem to work. When I blew air into the valve on top, bubbles did come out of the "nub" in the motomassage. Is there a chance that there is an air inlet that could be clogged and not let air into the line in the first place? This would explain the collapsing air hose on the motomassage. All of the rubber seals on the valves look fine, so no rubber chunks should be causing the blockage. Thoughts?
