Review on Beewarm Replacement Pump for 84oz/2.5L Cat Water Fountain - Ultra Quiet, Long Life Span, 6ft USB Power Cable - DIY (Water Pump) by Stephen Tharpe

Not sure what happened to the original pump, it may have run dry. Two cats drink a lot. This is the same model as the original, seems to work fine. Good price and I will buy again. Because you know the list won't be the last time we dry it. My only complaint is the light, which has to fit into a small groove/mount behind the pump. The new one has a larger stripe and is just styled differently. It doesn't fit into his groove. I had to twist and manipulate the cable until the light was at least where I wanted it to be.
