I bought a cricket head, based largely on advice from this ng. My
experience with it is mixed. It is slightly better then the
piston-pump W-C it replaced. I think after having owned it, I can
make some observations.

The REAL problem with the Cricket is actually an "operator error,"
common among owners of most toilets, but the Cricket is much less
forgiving: incomplete flushing...ceasing to pump as soon as the bowl is
empty. In most toilets, that only leaves waste and/or TP sitting in the
discharge hose where it rarely creates a clog unless someone flushes
something they shouldn't have. But because the Cricket's pump is just a
large diaphragm directly below the bowl, unless the use continues to
pump till all the waste is pushed out the discharge on the side of the
pump, waste and TP build up in it, blocking the discharge, till it
produces the backpressure and eruption you describe. After numerous
attempts to design a flapper valve strong enough to resist the pressure
needed to break up the clog and send it downstream, Raritan--also
knowing that few if any boat owners will flush enough to keep waste from
building up in it--finally gave up and discontinued production of the
Cricket this year.
