"My son-in-law and I both had to replace our sump pumps at the same time. We installed the Simer model #3988. The pumps work great, but suck a little air at the end of the drain cycle--not a big deal. This seams to be common to the pumps.
I only thing I don't like is that it uses two electrical cords--one plugs into the other one.
I have to rate it 4 out of 5 stars because it sucks a little air and the two cords."
