We are camping for the first time this spring and the water pump is not working properly. Not much pressure and wouldn't turn off after using water. It sounds like it is going to die now. We are having trouble locating the water pump in our 2020 Sabre Cobalt 270RL. My husband blew out the lines for winterizing just as he did with our previous 5th wheel that we owned for 8 years. I have not been able to find a plumbing diagram of our camper. Would appreciate any help you can give us.
