I don't think that would work. Pump would suck the bag into the
impeller (how do *you* empty it?).

In use to flush I just dip out water with a pail.

Tipping the barrel over (to empty
it completely) would cause the bag to flop out

Yes. Not that difficult to put back in. I rarely empty it. Dip out alga
as needed with a pail.

(I guess some
double-sided tape near the bottom of the barrel could minimize this
problem).
