Bathroom plumbing gets a lot of wear and tear, and is the most likely place in the house for leaks to develop. That's why bathroom plumbing is one of the most scrutinized items on the home inspector's checklist. Moreover, much of the plumbing in the bathroom, particularly for the shower and bathtub, is inaccessible, so that if and when leaks do occur they can go unnoticed for a long time. This can result in unwanted moisture damaging wood and/or attracting infestations of wood-destroying organisms.
I inspect bathroom plumbing methodically, deliberately, and thoroughly because of this significance and these ramifications. I have completed proper training, been the recipient of invaluable mentorship, and picked up some plumber secrets along the way. Allow me to share my approach to inspecting a bathroom and all of its varied plumbing.
