I need to install a sump pump in an existing outdoor crock to stop water from backing up in to my walkout basement. The crock is about 5 ft deep and 18" across. I'm getting various opinions as to whether the pump will freeze (I live in Michigan) and how to prevent that. Suggestion has been made to wrap heat tape around pump to prevent freezing. Also has been suggested that using a heat wire like that used for roof edges in Winter inside the drainage hose for the discharge will work to keep the discharge from freezing. Thoughts, ideas?
