Have to share this…Just finished te CE on Plumbing overview and forgot to post to the forum.
Short version - Went in a home and was talking to the owner about the tub overflow a few years back and the floors had to be redone, etc…
I asked the owner if any one explored why the tub had over flowed, (besides the forgetting about te water running part) she wasnt sure where I was going so I told her and showed at the same time - as I reached down and unscrewed the the overflow cap, presto - no change-o - the red paper cover was still on the overflow drain.
So I stated the obvious - thats why when you forgot about the water running - your tub over-flowed because at install they ? did not remove this cover to the drain pipe. So the water had no where to go except onto the floor and out the door…
WOW…!!! what a mess that was and what puzzled me was - no one in the line of contractors along the way when repairs were being done thought to look for the cause…hmm.
