Thought I would pass on this tip. As part of my water use reduction project I've wondered how often per day any given toilet is flushed. Numbers range from 6 to 10 times/day per person in various sources. Of course this varies depending on how much one is actually at home, among other things. Trying to keep track of it manually was likely to miss a lot of flushes. So I started thinking about a way to make a flush counter and realized I had an ultra-cheap pedometer handy. I clipped it to the toilet lever arm and voila, a poor man's digital flush counter.
