So I did approximately a week's worth of survey on each toilet. My assumption had been 8 flushes per day per person distributed among three toilets. The counter worked well overall, although I did have some doublecounts and no counts on one of the flush levers that required some repositioning. The actual result: 8.7 flushes per day/per person total. With colder weather and the end of outdoor sports we are inside more, particularly on weekends, so that ups the count slightly. So my initial assumption was pretty decent. If nobody was home during weekdays it would be considerably less.
That is a lot of flushes per person per day, (8.7). Someone must have a bladder problem and possibly diabetic.
Nope, that seems pretty normal if one stays well hydrated and is "regular." Since there are three baths among 4 primary users it's pretty easy for me to see that the use is not concentrated in any one bath/any single user. Nobody in the home is diabetic at least based on misc. health screening a few months back. Folks that were home less would easily see several fewer flushes per day/per person.
