In my closet downstairs, there is a chrome cover leading to a black
cover, approximately 4 inches in diameter. The cover has a large slot
for a straight edge screwdriver. Behind this wall is the restroom.
I'm guessing this cover leads to the plumbing system. Can someone
confirm this or what is this for?
