Chances are it's frozen if there was water left in the pump. If it thaws out and there is no damage, I would recommend running rv antifreeze or -20 windshield washer fluid through the pump before storing in colder temps. I'm a bit nervous myself. I noticed I forgot to drain one of my water filters and it busted last nite. Just hoping I've got all the water blown out of my hose reels. The temps this week are much colder than we are use to.
