A Lavak is really a manual VacuFlush. We have had both and prefer the
Lavac.

Have had my Lavac for about five years, one of which was under liveaboard
cruising use.

You cannot imagine the simple pleasure that pumping the Lavac provides! I
don't think anything on the boat functions as perfectly, or as
satisfyingly, as the Lavac. Well, except for the keel. Except at low tide.

Never clogged. Never had to replace the seat seal or the pump parts. Easy
to clean and keep clean. And the power . . .!

I guess they are more expensive than the lowest priced alternatives, but
surely less expensive than some. None is better, IMHO.
