Hi Some advice required please.
I currently have a trolley system that I use. I want to upgrade my van to have a the tank in the van. Dont want to have filter system in van as I can transfer my purified water to the van. What sort of pumps battery etc is needed.
Many thanks in advance

Why dont you use your trolley as a van mount? all you have to do is extend the pipe going into your trolley so it goes to the tank then from the outflow of the pump to a hose reel.

Easy as pie....
