I had a 'high volume' flapper in a 'low volume' toilet. Nobody but me will ever notice the change, but it'll save water and flush better.

Now I am curious as to what a flapper is!!

Do you notice how going back to some place that was familiar long ago, seems so foreign? It was weird the last time I went to my home town in Australia as while I recognized the majority of it, it still felt alien, like it was more from a dream sequence. The locals of course, they have been part of the change, like the proverbial frog in the boiling water, not noticing the shift in temperate.
