Just finished my afternoon pump. Right after my let down the pump started making this weird gurgling sound and didn't seem to suck as hard. I checked all the tubing, connections etc. The membrane looks okay, but I'll probably go ahead and change it tonight anyway.
I read somewhere that there might be milk in the motor and that I should try running water through it? Any idea how to do this or if that might help? I really don't want to have to drop $250 on another pump if I don't have to!
