I think most of us take indoor plumbing for granted. Especially when 160+ kindergarteners have to go to the bathroom right after lunch before they go out for recess.
But today, there was a glitch.
The girls' restroom was closed due to a "problem"....a stopped up problem. And the boy's restroom right next door ended up being closed because when they flushed, it came back up in the girls' restroom.
A plumber was called out with the snake.
A rubber door stop had been flushed.
Door Stops. They do more than stop doors.
