Many of their systems are supplements to the main sump pump, and not combo systems.Lots of things aren't made the way they used to be made. Everyone makes great points and since we've had a drought here, I've been digesting information. It's like when I'm advising my friends with smart home tech. Most of the major brands (and upstarts which is kind of funny to say relative to a new segment like smart home tech) will do most of what we want. The question is what ecosystem do you want and how do you want to accomplish it.
I've got a Zoeller M63 and check valve sitting on my kitchen counter. I keep going back and forth about getting a Basement Watchdog unit with a battery backup. Don't want to be short-sighted (knock on wood) but we very rarely lose power.
Can you add a backup battery at a later date? Or is it one system? Hard to tell. Rain is finally coming so I've got to get this done.
Thanks again for everyone's advice.

I don't have a battery backup myself, but I do have a generator that I have never run.
There are also city-water-powered pumps. Venturi type pumps, I think. That could be expensive to run. If you have your own well, that would not be worth considering, of course.
