Two of my neighbor's 5th wheel's won't draw water from a bucket from their "water" station. A little bit of water pressure seemed to fix the issue.
Here is what I use:
12 volt marine (water) pump. I got mine form harbor fright but other vendors have the same one.

7 gallon aquatainer

Garden hose quick disconnects:

The thread on the quick disconnect does not match the thread on the cap which is for a spigot. Heating the male quick disconnect fitting melts the plastic and allows you to get your own threads and ensure a leak free seal. First time I did this, I forced the quick disconnect on and cross threaded it. The cap eventually split; has been good for years using heat.
Use a white water hoses to feed the pump and run pump output to fill hole or your water "docking" station.
12 volt power sources for pump: At first I used a portable battery jump starter, then I used my ATV cigarette lighter power, and occasionally the 10 amp output from my generator. I now have permanent power in a weather proof aviation plug mounted on my exterior wall next to my fresh water gravity feet hole. Makes the whole power issue a non-issue now.
We also put a little water sanitizer in each water jug. While it does make the water smell and taste bleachy we found it allows us to extend showers two 2 days when boondocking. The bleach does a good job killing body bacteria responsible for body odor. Its no stronger then swimming pool water.
No, we don't drink the water from the camper's FW tanks and only drink pure distilled grain spirits. “Do you realize that fluoridation is the most monstrously conceived and dangerous communist plot we have ever had to face?” I have this information from a good authority, Brig. General Jack D. Ripper who I served with in the Army.
