I have two of these pumps in my pond, they run 24 hours a day every day 356 a year.Over the last 20 years I have gone thru , mabe 10 or 12 . They last a long time very low maintenance and very tough.I had one last winter, the string on my floating thermometer some how got wound up in the pump and it quit working so I ordered a replacement pump.when I pulled the pump out to replace it I was Abe to cut out the string plugged it back up and it started working
The warranty isn’t good it says three years I had one a little giant 4200 for eight months now I have a 3500 don’t expect any warranty on this one ether.
