I replaced my main therapy 2-speed pump about 6 years ago because the original one had gotten too loud. This 6 year old pump also had become very loud and one day it just stopped working. When I try to run the jets at either speed, I hear a slight click, but the jets don't come one. Same happens when they are supposed to automatically come on after power is turned back on or after the normal 12-hr period.

I have also noticed that my circulation pump is now quite loud and that originally and for many years had been basically silent when running. I looked on the HotTubWorks site and they show a 2 speed 2.5 HP pump for Sundance and they list several models, but not the Caprio ST. Should that be pump I order? Also, how do I determine what circulation pump to order?
