Best way to put water in?

[Rustyone]

Hi everybody.

I've read here and on other PUP sites that it can be very difficult to pour fresh water into the tank of a PUP and if I understand correctly is like putting gas in your car only you have to raise a container up and pour it in by hand.  This is not something I nor DW can or want to do.  My question is could you use a DC pump mounted somehow with the necessary electrical and water connections  briefcase style so that you could just bring the fresh water container to the PUP, put the one side of the hose in the container, the other in the the PUP, hook up alligator clips to the battery and just pump the water in that way?  What type pump would work?  All I can find is on demand pumps (Shurflo).  I think I can figure most of this out myself but I'm confused about these "on demand" type pumps.  Would that type pump work in this application?  Could you wire one of these things to a simple toggle on/off switch?  There has to be some sort of sensor in the on demand pumps that would need to overridden considering the nature of the beast.  What I'd like to be able to do is pull the truck within 10-15 feet of the PUP, hook up to the battery on the tongue, run the necessary water lines and flip a switch.
Input would be greatly appreciated..

If you can access the outlet line from your tank before the pump you can just T a hose and pair of valves in.
     
 Cut the line between the tank and pump. Install a shut-off on the tank side then a T. Attach the opposite side of the T to the pump and put another valve on the last pipe in the T. From this last valve you can attach a hose that you drop into your freshwater refill source.
     
 Close the valve from the freshwater tank and open the valve that goes to the hose in your freshwater refill source. Now you need to attach a hose adapter to your faucet, hook your freshwater hose to it and place that into your onboard freshwater fill hole on the side of the camper. Turn the faucet on and the pump will pull from your refill source and come out of the faucet and go into the onboard freshwater tank. Once you have drained your refill source, you can close the T valve from the refill source and open the freshwater tank outlet valve and resume normal operation.
 
 My hybrid has this as a standard feature so you can pull RV antifreeze throughout the system without putting it into you freshwater tank. The hose you drop into the freshwater refill source is a soft vinyl clear hose. I tried the method of holding the jug and pouring it into the tank and it is no fun.
     
My crude drawing below should help.

Now this isn't something I have to worry about, since we just have a removable 5 gallon tank that we take out to fill, but I do have another thought if you want to keep expense for pumping the water a bit lower.
 
You can buy a simple water pump that attaches to a drill for not very much (I have one that we used to use to empty DD's wading pool when she was little, and still use sometimes when we want to empty water out of something and don't want to haul the portable sump pump out). If you have a rechargable drill (or possibly a powered screwdriver, if it will move it fast enough) you could use that to pump water from your hauling tank into your holding tank. The drill-operated pump that I have hooks to a standard garden hose fitting on either side. Get a 10' (or less) drinking-water hose, cut it in half, and there you have it. Easy, portable, storable, rechargeable pump for refilling onsite. And if you already have the drill for a Socket Jenie (or your standard "mod" toolkit), you're already set in the drill department

We just use one of those battery (2 D cells) operated pumps meant for Kerosene. Sanitize it first with a light blach water. Stick it in the jug and the other end of the PU ,turn it on....it works and is not costly

I use a Coleman collapsable 5 gallon water container, and the Coleman battery operated shower pump, which screws onto the filler neck. I fill up the collapsable jug, carry it over to the trailer, screw the pump onto the jug. I take the shower head off the plastic tube, put it in the filler cap. Turn on the pump, and viola.
