I feel your pain about water lines. We had a ruptured water line that just happened to be on the "our" side of the water meter. That was not a pretty ordeal nor a cheap one!
If you are consuming more water than it seem financially feasible for your snakes, an RO system is not that ridiculously expensive and will remove all particulates and contaminates. I had one hooked to an 80 gallon drum for my saltwater tanks. Saves a ton in the long run.
