Most of us have no reason to peak our heads around the back of our toilets and I’m sure we all have better things to do.
Since the toilet is the lowest fixture in the bathroom we may overlook it is leaking and causing havoc behind the walls.
As a housekeeper and home watch manager we see this while cleaning behind the toilets too many times. Check for water dripping, broken shut off valve, and a leaking pipe. Plumbing issues should always be first priority to avoid much larger problems.
