Query: Defective

Product was defective - you don't find this out until you have it totally installed and the pump only pumps for 10secs. Contacted manufacturer and was told having problem with the float switches so sent me a new one. Of course new one didn't fix the problem so I was told it is the controller box that is attached to the battery case. Was told to contact Amazon.com to get a replacement controller. Amazon's way of fixing it is to send a hole new pump set out and remove everything that I got installed and replace with new pump. Package all the old/bad items up and return. It sounds simple but with all the rain we have been getting around here it is very hard to remove and install a new pump when the water is filling up faster then you can do all of the work. The control box can be simply changed out without removing everything. Working with manufacturer to try to get new controller. if it doesn't fix the problem I would not recommend this pump as it only pumps for 10secs and then shuts off.
