12 volt transfer pump

Since we dry camp a lot with sites with remote water I came up with this solution.

a) mount a RV water pump in our pass through near the water inlet
b) wired the pump in with on/off switch
c) outlet tee into the fresh inlet line
d) inlet flexible tubing with SS dip tube

I use the blue 7 gallon water jugs, stick the dip tube into the weater jug, turn on the pump.

Works great and game me a reason to replace the noisy OEM TT water pump. Put a higher quality, quieter pump as the main pump and used the old OEM as the one in the pass through.

I thought modern RVs had a place to suck antifreeze out of jug, pump it thru systems. If you stuck that in a tank of fresh water would it know the difference?
Before go to refill portable tank use outside shower to MT into gravity fill.

I added a 3-port valve to the inlet of our onboard water pump that let's me draw water from portable water tanks to refill the onboard tank using the existing fill/use valve.

We decided to replace the MH with a smaller TT, we are done traveling so it is a better fit. We own our own camping spot on a local river so it will sit there most of the summer unless the river floods then it will come home. Got a portable waste tank I can bring home and dump in our septic system. I will need to fill the fresh water so I am looking for a 12 volt pump for that. Anyone have a setup that works well for them? Thanks in advance, Jim.

I bought a 40 gallon water bladder and a ShurFlo water pump. The pump is identical to the one that is in my TT. I put a male hose connector on both the pump inlet and the pump outlet. I also attached battery clamps and an ON/OFF switch to a long cord to the pump. All of that is in this plastic container. (Note that I DID fuse the power cord.)

I use a hose to fill the water bladder, and close it off with a hose end shut off valve. Then I drive to the TT and hook that same hose end up to the input side of the pump, and my regular "fill the water tank" hose to the pump outlet. I then hook the pump to the battery, turn on the switch, and it fills my 40 gallon water tank in minutes. No lifting water jugs.
