I recently picked up a tub for free at a garage sale only to come to see why it was free. I have now had it up and running the heater works great, recirculation pump no problems, but there are some leaks. I now have come to the pumps, One pump apparently runs only one seat and the other the other six seats. No blower on this model and I just pulled two broken jets which seem to help on the pressure but not a lot. I also noticed that when I turn it to floor rejuv jets on the control panel it turns on wall jets floor jets all at the same time is this normal? Any help would be great and a diagram of the plumbing would be better. Thank you again for your help if you can".
