Mobile Water Tank setup....need a little help

[3Crowns]

I honestly wouldn't use that switch because frankly it looks like a hunk of garbage and if that's the switch from your non working setup it could be the problem. I'm a huge advocate of eliminating all potential problems from a non working setup and adding them back in after you get it working in it's simplest form. Honestly, you don't NEED a switch. You can hook up the pump directly to your power source. The Shurflo is on demand, so it only runs when pressure drops. Pressure only drops when you're using the pressure washer. You could alligator clip it to a battery and unclip it when you're done.

In our setup, for example, we switch the pump on when we get on the jobsite and we don't turn it off again until we leave. That might be 2 hours or 10 hours. The Shurflo doesn't need to be switched on and off continuously.

Good deal. I believe I can head to Lowes and get some additional length of red and black wire and wire those ends into some cables that will hook to my battery, and like you said just clip them on when I'm pulling from the tank.

In my pic, you can see I did just that. Long red and black wires so I can run from the front of my Jeep, all the way to the back in the cargo area. Sometimes I turn the Jeep on, sometimes I don't. Depends on how much time I plan on running the pump. I'm guessing it would be better to run the pump off a running car, though. 12+ volts instead of the 11.7-12 volts with it off. (or whatever number it is)

12VDC motors like that pump will basically work from about 8 to 16V. DC is not exactly what you'd call finicky.

For those still following the thread, I wired up the new Shurflo pump and it works like a dream! Thanks for all the advice and recommendations guys!

Just anecdotal evidence, but we run our trailer with a deep cycle group 27 marine battery that is wired to our tow vehicle through a 6 pin trailer plug. Unknown to me, my son blew the fuse that feeds the trailer plug fiddling around with a 12v power port inside the vehicle. The battery was not charging for like a week. Voltage dropped in the trailer battery to 8.2V before the pump actually quit working. I could hear it straining, starting, stopping, which is what made me investigate the problem. I popped a fuse from the front power points into the blown fuse spot and we were back in business. It took a full day for the battery to charge by near 12v.
