This is a very reliable pump. It has very few moving parts, and that makes it very durable. I had to replace the pump that I was using in my fountain, which was also a Cal P80 pump, because I failed to turn it off while on vacation. As a result of this, the pump burned out when the fountain went dry. The company supplying this pump for Amazon was super with its service. Within three days after placing my order, the pump was at my door.
