Pumping water/dry camping
My new rig does not have an separate external filler for the fresh water tank. Unlike my old rig I have to connect to the city water inlet. When hooked up to city water I can fill the fresh water tank with no problem; however, when trying to pump into the city outlet using my 12v pump and water tank in the back of the truck it’s another story. I have a Shurflo 4008-101-E65 12v pump I recently purchased for this purpose. This morning I pumped about 40 gallons in to the fresh water tank on the rig and it took an hour or so. The pump seemed to be operating smoothly but the hose on the discharge side seemed to be cavitating. When I took it loose from the city water connection and let it flow on the ground it did better but still not 55 psi. I am using a 25'x5/8" suction hose and a 10'x1/2" discharge hose.
The Shurflo house pump that came with the rig has a clear tube you can use for sanitizing the fresh water tank by resetting some valves so I tried using this pump. Observing the clear tube I could see that it was not a continuous flow of water, but had a lot of air. I have checked all the connections for tightness and I know I have good voltage. Two different pumps, same results. What is happening??
