I never wanted to argue Sam, I just haven't seen what your describing happen before. I can see the pool that you mention being sucked back into the pipe after a sub shut off. It would only take a small leak below that spot to cause that vacuum. This is the reason a lot of say not to install a check valve at the tank or anywhere in the feed line. Without one the feed line stays pressurized all the time.
I think we are on the same page, it's just that we are describing it differently. In reality, the same thing happens, it just has a different movie title.
