Pat: A friend of mine would get milk in her PIS tubing if she pumped and got too much milk in her bottles, sort of like over flow, or if you really tip the bottles and get the milk to run up the tubing. You can just rinse the milk out of the tubing and then hook them back up to the PIS and run it for a while without the bottles/flanges to dry the inside of the tubing. If that doesn't work call medela and ask their customer service dept. They are really helpful.
