Can anyone tell me if you can manually flush an electric head when the
power is out?

Only if the toilet is actually a manual toilet to which a motor has been
added. Macerating electric toilets and others that were designed
specifically to be electric toilets cannot be flushed manually.

However, I've always been baffled by the big concern over whether an
electric toilet can be flushed in the event of a power failure...'cuz if
that should happen, so whether you can flush a toilet will be the LEAST
of your worries...you'll also lose all your electronics and engine...but
at least you'll still be able to use a bucket if you can't flush the
toilet.
