Most systems use 12v pumps. Lloyd said there was an trailer electrical problem not a pump problem. I use a motorcycle battery on my towable weed sprayer (same type pump as Scamp
trailer) and it will last for a few hours continuous run time, enough to spray the lawn anyway. It should only take a few minutes to winterize the trailer system. I was thinking rather than moving the big house battery nearer to the pump (to bypass the electrical problem) some other smaller 12v source could be used which has enough amperage output.
My pump is actually wired up to the inverter 12 volt terminal strip. The strip is then hooked up to the battery on the tongue.
It is really easy to connect wires to the pump on my trailer.
Anyway - a manual pump would work too.
