The pumps were used as directed. As far as being an isolated incident, Gene clearly stated in an email to me that they had many problems with the higher flow pumps. They had a circuit that was defective from the electronics mfg. that would prematurely shut the pump down thinking there was an over heating problem. I have all the emails and receipts to prove my case. Gene said he was going to take care of me, I have that email also, he has not done a thing yet. The resulting issues with numerous pumps going bad are far more than you think. Ask anyone who has had a pump go bad on their system. You lose a pump it is like losing your heart pumping blood. Things will die very quickly. One may be two pumps going bad after several years is one thing. But they have had an excessively high failure rate, also from DRF&S customer support people. When a pump goes down on a 525 gal. system, a $250 pump vs $4000 worth of livestock, you do the math. That is why I spent top dollar for the ReefFlo Gold series pump.
As for my request from Gene he offered me anything I wanted. All I asked for was an automatic feeder, a cheap little feeder. He still will not answer my emails. Sorry but Quiet One pumps are not worth the risk.
