Ok, well its been the better half of ten years now. And I am still trying to figure out if these thing even have a life expectancy. I have had now problems with it, except a pump seal wich was all of about 80 bucks. No complaints though. I love the fact that it has a floor drain that also cleans it. My tub has always been clear as a bell, with very little maintenance. I two years ago I converted it over to salt water. Amazing. I have drained twice since. Highly reccommended. Take care.
