Cheryl:

  if as you say "know that nothing moves thru the tubing but air " then what
is the issue... if the bottles in the storage compartment are sealed
correctly there should be no leakage SO...

   If we review the pumps on the floor - there is ONE with a hydrophobic
filter,   its portable version has an internal motor, the "personal version"
if milk is not "sucked" into th etubing it could not get into the pump.. has
anyone opened one up after use to see what does happen? the competetors model
has a silicone filter to prevent "splash back"....

    Maybe we should ask, at the appropriate workshop to see the insides of
these pumps.... after use!
