First post here. Looking forward to learning a lot on the forum.
So our new-to-us Montana is missing it's fresh water pump! I know what you are thinking, but hear me out! The water pump switch would light, but no noise and no water pressure. Checked with Keystone and found the factory location was behind the furnace, adjacent to the shower. I'd already looked thoroughly in this area, and it was not present. I could see where the fresh water hose came into this area from the rear mounted water tank, but it went straight to the water line manifold. Thought possibly the pump was located, or had been relocated close to the water tank, due to priming issues, but that did not make sense due to access and potential freezing problems. No screw holes or any other evidence of a pump being mounted near the plumbing manifold. Removing the hose, I was able to manually suck water easily from the tank, which determined that the pump was not somewhere in between. I then started looking very closely, and sure enough, I found a wire tucked away that had been cut with the ends left bare! I determined with a multimeter that I got 12 volts at this location, off and on, via the water pump switch inside the unit. Some jackleg mechanic had completely removed the pump and replaced the hose directly on the manifold barb!
So without a bad pump for reference, I am unsure what exactly I need! I'm pretty sure it is just a Surflo RV water pump, but I would like to match factory gpm and psi if possible.
If anyone has any insight, or can take a look at or picture of their pump, I would be very appreciative! Thanks!
