The worst thing a python system could do is plug up. That would be like turning off the sink water valve. Does that ever cause your sink plumbing to rupture? Of course not. So, neither can a python do that.
What it can do is pull on the sink plumbing. If you attach the python to the valve, then pull it or jerk it as you try to use it, the pulling might damage corroded piping enough to make it fail.
