Any opinions out there regarding a water powered sump pump as a back

system sounds excellent, as opposed to a battery and/or generator.

A water powered backup sump pump is no more independent than a battery
or generator powered one.

It's independent of the power source for the first sump pump.

In all cases the pump is dependent on an
external power source.

But a different one.

Almost everywhere, water pressure fails a lot less than electric power
does, and in the last 24 years here, the water has never failed when
the electric is out. They're independent of each other.

The main advantage of the water powered one is
the lack of maintenance required i.e. maintaining batteries or a
generator. Of course you have to have city water, if you have a well the
water powered pump isn't an option.

True.
