Picture it: you’re enjoying an evening home with friends and get up to go to the bathroom. You do your business, flush, and it goes down as usual... until something goes wrong. The waste is mostly gone but the water isn’t coming back like it usually does. There are still some scraps of wet toilet paper stuck in the bottom of the bowl.
It’s filling up again, but not as fast as it normally does. You figure you can wait until the problem works itself out. Then you hear a knock at the door.
