Worked well for several years but then started leaking.  First at the diverter valve.  Then at the spray nozzle.....then the diverter valve again.  Then another diverter valve.  Product support was ok, but really didn't listen to what was going on, so never got to the point of fixing the product and had to replace entire unit.   The diverter valves varied on the inner diameter of the valve to where I think the mating fitting could not seal(  sorry I am an aeronautical engineer and always look at why things don't work).  Anyway, spent way too much time trying to make this unit work and of course, had to put up with leaks an no water until replacement parts arrived.    Good news, bought another Pfister unit that had a different set up and, knock on wood, so far so good.
