Left pump out all winter in MO, dead now...

[tenax]

my 2 cents..if i had a heater/pump outdoors, once drained well, i'd cover with secure plastic.

Poolbee, type of pump isn't all that important, they all work the same - however, if you have a DoughBoy, the motors are shrouded and should minimise the effects of being left out all winter. (BTW - my brother lives in Jamestown and either you don't get the same weather or are a master of litotes).
What kind of heater do you have? The mice don't destroy all, they just get fried when it fires (:evil grin
