Hmmm, interesting, the one complaint a person using this system had was air in the water, which could perhaps happen if the filter canister wasn't on tight enough. Air would be sucked in, but there might be no leak?
I guess its possible, but it would be hard to imagine a scenerio with negative pressure like that all the time.
When I worked in industry we used vacuum systems for liquid coolant all the time. Even a pinhole leak could cause catastrophic damage so pumping the coolant through wasn't an option. We could tell when there were leaks because the vacuum units had systems that removed the air from the coolant and the worse the leak, the more air, and the less efficient that unit became.
In researching a problem with my car's gas tank (posted under a separate thread) I found out that if the gas tank's air vent line gets kinked or clogged the fuel pump can actually collapse the gas tank. That's got to be a lot of stress on the pump. I imagine the same strain can happen to the pump in a water system that is forced to pull water rather than push it.
