If you truly want to use potable water to flush your manual Lavac,
there is only one fool proof way to do it.

Leave the lid up, then add potable water from the shower wand, keeping
the wand 12"-18" above the bowl.

Don't bother to connect the flush water connection since you are not
using it.

A completely separate FW tank plumbed to the head and totally isolated
from the other FW tanks is every bit as "fool proof." On the other hand,
your suggestion is a good one because you could then use the water for
potable applications as well as for the head.

The only easy, economical way, probably. But I've crewed on a number
of trawlers (mostly Grand Banks) that have separate freswater tanks
for flushwater. Typically they are unpressurized, using a standard
head with an electric motor driving the pump mechanism.

Don't think it's worth the trouble, myself, but rich trawler owners
(and especially their wives) seem to be a lot more prissy than
sailboat trash like me.
