The wayne water pump sws50 failed after installing. I only ran for 5 min. then kicked the circut breaker. There must be something wrong with motor. I pur chased the pump to replace an aging pump that still worked so i was able to reinstall old pump. I did not get the pump installed right away. There was was 35 days from time of purchase. So i called the warranty hot line at wawne water pumps. they told me to send it back to where I purchased it. That any time I had problens with this product i would need to go through amazon. I called amazon would not send me another pump just refund my money and i may not get all of it back, because I was past 30 days.What a hassle I don't know if I will purchase large items again if manufacturer is going to give me a hassle about warranty because of where I purchased this item.
