I have only a standard and battery backup sump pump, no extras! So far the two of them have been adequate, but both have been running at the same time before. I have been thinking about a generator also, but don't yet have one. We are in a new home (4 years ago) in a new development they are still developing and all utilities are underground, haven't had many problems with power outages. Our old house had overhead power and there were a lot more problems with power and wind, storms, etc.
I argued with the builder about it being their responsibility to include the battery backup sump pump, but lost that one so we had to have it installed. Then the builder installed standard sump pump failed about 2 months after the warranty was up. Somehow that figures...
