These were the pumps that were installed with my boiler when I moved into my house. The first pump started "squeeling" after less than a year. The ball bearing broke. The second pump started squeeling shortly after that. The third went early this year, and the fourth broke a couple weeks ago.On top of that, one other one is starting to make the noises that I've grown to associate with the pump going bad. So soon it will be five bad pumps.This is the worst product I've ever used in my entire life.
