Any opinions out there regarding a water powered sump pump as a back
up for an electrical sump pump? In theory, an independent back up
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.

So is a battery pump or a generator.


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

But a different one.

In all cases.


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.

Yes, but a water powered pump is still reliant on an external power
source.


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.
