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.
