Should I get a battery backup or a water-powered backup sump pump?

More detail

The choice protects you during the power outage that so often accompanies the worst Cincinnati storms, which is exactly when an electric primary pump is useless. A battery-backup sump pump is a second pump in the same basin run by a deep-cycle battery; it takes over automatically when the primary loses power or is overwhelmed. Its strengths: it installs in virtually any home regardless of plumbing, and a healthy battery runs the backup for roughly 5 to 12 hours of intermittent pumping, which covers most Duke Energy outages. Its tradeoff: the battery is itself a consumable that lasts about 3 to 5 years and needs periodic checking, so it is installed with a monitoring panel that warns you of a weak battery before you need it. A water-powered backup uses your home's municipal water pressure to drive an ejector that pumps the sump out, with no battery and no electricity at all, so it can run indefinitely through even a multi-day outage. Its constraints in Cincinnati: it requires adequate municipal water pressure, so it works on city water but not on a private well; it consumes potable water to move groundwater (roughly 1 to 2 gallons of city water per gallon pumped); and the connection is subject to MSDGC backflow-prevention rules, which we handle. The decision usually comes down to your plumbing and how you use the home: a water-powered backup is attractive for a home on city water that may sit unoccupied during long outages (a second home, frequent travelers), while a battery backup is the versatile default for most occupied Cincinnati homes and the only option for homes on a well. Some homeowners with high storm inflow and low outage tolerance install both. We talk through your specifics on the assessment rather than defaulting to one.
