The very end of the filter, where it connects to the fridge, developed a small leak. Enough of a drip to cause problems over time, but not enough to make a significant difference in water pressure. The leak must have worsened during a stretch of time where we were out of the house for nearly 36 hours straight, and hadn't passed by the fridge to notice the puddle on the floor. I'm told that no shut off would likely have noticed the leak, as the difference in pressure was almost certainly too little to triger it.
Floor boards were noticeably swollen and edges were visibly discolored.

Not much you can do in that case.





At least with my lens~
