HI all my sump pump just bit the big one get a new one but the new one is shorter the the old one. I know what i have to do to make it work but i live in Niagara Falls Ny and we are starting to see a melting. I can not put the new pump in to the pit the motor and all would be underwater. I have to stop the water form getting in to the pit how do i do that? I only need to do it to get the new one. Any ideas?
