Running water pump '73 Tradewind?

I'm going to be boondocking in Ricketts Glen State Park Pa. next week. I will be using the water from the tank (fresh water) I will be on battery power. How long do I run the water pump? does it build up enough pressure and turn off automaticly? (doubt it) or do you shut it off when it stops (pressure stops motor) I don't want to burn it out, and I how I don't have to run it each time I want running water. Thanks for your responses! John

With my water system the pump turns of when pressure is achieved,
but i have 2 accumulators on my system each holding 5 lts, so i can open the taps and run a bit off without the pump starting. If your system is original i dont think you will have them, so you'll have to run the pump. but it should not burn out most can be run dry for a short time without much problem.

hope this helps

Most water pumps in these rigs are demand pumps. They will run until pressure reaches a set point ( mine is set at 45 psi.) When camping without hookups, I leave mine on and hear it every time I open a faucet. You can hear it slow before shutting down with the pressure switch.

The pump is controlled with a pressure switch.
Have you checked everything for leaks prior to going boondocking?
We turn the pump off after each use.

Hi moparjohn

If you have the time before you leave consider installing an accumulator, a small plastic ball with a diaphragm air on one side and water on the other. This will allow the pump to cycle on and depending on the air head you have set will allow you to do short draws of water before the pump cycles again. Even with this I would turn the pump off when you know you will not be drawing water for a while, ie leaving the trailer.

Watch that hill up to Ricks Glen. I had to drive 50 miles out and around to Williamsport to keep from coming back down it. Great campground just a hell of a hill.

A properly functioning water pump should automatically turn on when water is needed, and turn off when the tap is shut. It needs no attention from the user. The only time I turn mine off is when actually driving (if I remember it) and when I come back home. It can even stay on when the city water is hooked up as that pressure will generally be higher than the set point of the pressure switch on the pump. It is of course not necessary to leave it on, but it will not hurt it in any way.

Virtually all pumps made now can run dry without any problems. They use rubber valves and diaphragms and are not damaged by having no water in them. I have run them by accident for several hours without any issues. The motor may become very warm though.

thanks all!

I was hoping that it worked that way, Howie, I'm familiar with the hill, will be the first time with trailer, I'm not too worried. John
