Hi Dirk, I don't use a water pump from my 120 gal water well. I have it set up for my pump which is a Hawk brand sucks straight from my tank. I have also modified my tank with an other float valve installed near the bottom of the tank so we have the option of carrying just 10 gallons and hooking up just like those without a large tank or filling and carrying a full or somewhere in between amount of fresh water.
On my
prochem unit we did have a small water transfer pump that gave us trouble a few times over the years..
