I've been wanting to set up a pump system to transfer water from my truck bed into our travel trailer for a couple years. This last weekend I went to Harbor Freight to pick up a 12 volt water pump. Once I got there and saw how lite-duty the pump was and how short the leads were, so I changed my mind and bought a AC powered cast iron pump which is much more capable. http://www.harborfreight.com/1-inch-...pump-1479.html
I figured one way or the other I'd have to start my generator so I might as well just run the pump off AC.
Started out with the issue of going to from 1" to 5/8th-- no problem-- PVC to the rescue.
Next hurtle was the priming issue. This is not a self priming pump so I rigged up a 5 gallon tank to accept a 5/8 hose. I bought a cut off valve and screwed it into the tank.
Next I had to wire the pump up. I bought a 14 gauge extension cord and cut about 6 feet off the male side and wired it to the pump. Then I drilled a hole in the plastic cover installed a switch.
The pump is extremely fast. It drains the 40 gallon tank in about 4 minutes.
All I have to do is back the truck up in front or on the side of the trailer, plug the pump in to the trailer, turn on the generator, and prime the pump.
Plus I can the pump to drain our pool-- works perfect. A self priming pump would have been nice but it's not a deal.
