OK, Bulley, Try this:  Put a splice in the hose coming out of the sink trap
with a shut-off valve and hose,  then put your bucket (ridged or collapsible)
under the sink IN! the cupboard with the by-pass valve and hose going into
the bucket.   I could write at length about refinements to make it leak-proof,
but your a resourceful guy  :-)    BTW we have a nice box that goes aft of the
pass. front seat that really takes the heat off the need to have storage in the
sink-trap cupboard.   Malcolm S
