I can't improve on anything you said, Jeff (left intact below). In fact,
unless you object, I want to save it to my files to use in my own future
replies.

Your note that manual works better than the electric is true of all
"electrified" manual toilets. Putting motors on manual toilets does
nothing more than replace the pump handle...they're still manual pumps,
and motors do not do as good a job of pumping as people do.

I've had a Lavac on my cat for 7 years, which includes a year cruising
plus about 7 weeks aboard each summer.

It was originally a manual, but shortly after moving onboard I sprang
for the electric pump in order to save my elbow. If you want the manual
version, consider very carefully where the pump will be placed.

The manual works better than the electric, because you can give a mighty
tug to dislodge anything that might try to stick in the flapper valve.
The electric is too slow, so once or twice a year I have to open the
pump to clear it - that takes about 20 minute, so its not too bad. I
keep two spare manual pumps (the original, plus one from a clearance
table) so I know I have options. Its possible to put a manual in series
with an electric, and theoretically get the best of both worlds.

One downside of the Lavac is that it defies description to
landlubbers. Guests will generally "hold it" rather than confront it.
And when it was new, it was far beyond the capability of our then 3 year
old. Now she's 10, so she should be able to only need occasional help.

While its not perfect, it has advantages for the dedicated cruiser.
However, if I had to do it over, I would consider the other vacuum
systems - Peggie can hopefully give her opinions on those.

Whatever happened to Monomatic recirculating toilets? I replaced the cheap
RV flusher on a motorhome I had a long time ago with a Monomatic. With the
recirculating toilet dumping into a 33 gallon holding tank, you only had to
go to a dump station once a trip! I got the Monomatic for free from an
Airstream owner whos squeemish wife just couldn't understand flushing with
the same water over and over...(c;

Those things still made? They worked great!

It was discontinued about 25 years ago 'cuz you were one of the few
people who liked it.

Danforth also made a recirculator for a while in the '70s...it didn't
last as long as the Monomatic, for the same reason.

The marine versions were actually certified as Type I MSDs, intended to
be discharged overboard when full. They weren't too bad when used that
way, 'cuz they only held 5 gal, 3 of which was the "charge" of chemical
and water...they were dumped often enough to keep 'em from stinking. But
when they had to go into a tank, PEEEEEUUUW!

Thanks for the info. Guess I'm not grossed out as easily as most of the
population. It smelled like the chemical mix in it, formaldehyde-based
which was probably its demise.

Formadehyde wasn't the reason...there are still several formaldehyde
holding tank products on the market. And some "non-formaldehyde"
chemical products that are equally, if not more, lethal.

Recirculating waste works well in large systems like those on
jetliners...it's an aesthetic horror, both sight and smell, in small
systems.
