Can you say Lavac?

Lew
I have an electric Lavac and would not recommend it. The electric
pump is not quite strong enough to always clear the waste. We're
rather careful about what goes in, but at least once a season
(sometimes once a week), I have to open up the pump to clear it. We
started with a manual, which was OK until we moved on board and had to
use it full time - the adults on board developed "lavac elbow" and the
5 year old couldn't begin to work it.

On the plus side, I can pull the pump out and completely strip it
down, clean and replace it in about 30 minutes now. If needed I can
put in the manual pump even quicker. The head itself has never
clogged and with three onboard the holding tank fill at about 4
gallons a day. Although some point to the seal system as a weakness,
it isn't really needed to empty the bowl, only to draw in water.

One more thing - although a Lavac seems like simplicity itself,
explaining it to guests always draws the "maybe I'll wait until we get
back to the marina" look.
