I have a simple question about RV water pressure pumps. I'm going to be installing a seaflow water pump, but there's just one thing I'm unsure about. I'm going to mount the pump on the wall, and am unsure on which side of the pump should be up and which should be down. I've seen them installed both ways on the internet, but which is the correct one? Should the water hose connectors be on the bottom or on the top?
