Can water pump burn out if left on too long?

I just got back from picking up my TT from getting winterized.
When I went in to check it out, I noticed the battery was completely dead probably because they had left the water pump switch on .

They came out and charged up the battery a bit, but we had to keep the TT plugged into the truck so the power jack would work.
When we had it charging, I went back in the TT and turned the water pump switch back on to see if it was working, but I did not hear a noise from it.

So, I have two questions:

1. Will the water pump make a noise when turned on even if there is no water in the system and the lines are empty?
2. Is it possible to burn out the pump by having it on with no water in the lines, for 1 or 2 days?

Most shurflo pumps can be run dry without harm
if no water is present pump will run with no noise
check your pump documentation to see if yours is a "run dry"

I left my pump on during winterization overnight and the next morning the pump was still humming. I heard it as I walked past the camper on my way to work. It was not pumping water. I turned it off. Mine clearly was audible.

Hmmm...idk if it can run dry or not...can't find it in the information sheet. I think that there is a breaker in the pump itself that will shut off if it gets over heated. The motor might still come on, but it might not be able to suction properly, and won't work.

I try adding more antifreeze and turn the pump on to see if it does work still. I would rather do that now than in the spring.

Any other suggestions?

I might fill the fresh tank with some antifreeze and turn the pump on to see if it does work still. I would rather do that now than in the spring.

If it's broken, you're not likely to replace it until spring anyway. I'll be waiting until then. But my line of thinking maybe unconventional. It won't harm anything now .

They probably didn't add antifreeze to your fresh tank rather they unhooked the fresh water supply line to the pump and sucked antifreeze from there.

Really? What did they say when you told them about their mistakes?

As for the pump, I think you would almost need to test it to check if its still OK. Kind of a hassle if you just winterized, though.

Make sure to fully charge that battery. Overdischarging can shorten battery life and inadequate charging can lead to sulfation. Leave it plugged in for awhile before you disconnect for the winter.

Kim,
Do you have a winterization kit on the line leading to the pump?

I have a antifreeze outlet on the side of the TT next to the city water intake, but it has a strainer over the opening.... so can I use one end of my fresh water hose to attach there and put the other end in the antifreeze jug?

I'm sure your pump will make an noise if you can get close to it. Mine is MUCH more than a loud hum, dry or wet.

And---it's not a bad idea, if at all possible, to put a "top-off" charge to the battery now and then throughout the winter..If not possible, give it a good 6 hour charge and disconnect one of the battery cables before storing.
