Flojet 03526144 came new in our 2020 Keystone Passport. Last fall on our last trip of the year, the fresh water pump wasn't pumping water to our faucets. Plenty of fresh water in the fresh water tank. We'd hit the switch, and no dice, it would have kept running until it drained the battery. I thought there were two possible causes. Maybe the impeller in the pump failed, or maybe it was because I TOTALLY emptied the water system the week before we left, and the pump doesn't have enough power to suck from the fresh water tank when the system is dry. I ordered up two quad connects and some tubing to test the pump outside the camper. When I manually primed the suck side, it ran just fine. When the in and out hoses were dry, the pump did not have enough suck to bring water from a 5 gallon bucket on the inlet side. So I demonstrated to myself that when I prime it, it works fine, but if the system is dry it won't prime itself. Now. Has the pump failed, or did I screw myself when I totally drained the system dry?
