In light of the current drought in California, I have revisited this issue since the last time I wrote about it . Water conservation must be one of the easiest things we can do. According to an article posted by the Sierra Club, the three biggest sources of water consumption are: The toilet (26.7 %) The clothes washer (21.7%) The shower (16.8%) The article mentions that there is huge variability of course, and it is not clear what is used as a base line here (a 1.6 gal/flush toilet or something with higher consumption, what kind of clothes washer, and what showerhead etc.). At any rate, changing out a toilet can cost anywhere between $200-$500. Changing out a decent clothes washer can run anywhere from $700-$2000 for high-end clothes washers. A showerhead, however, will at most cost about $80 for which you will get a luxury showerhead while having the potential of cutting the water usage more than half! So they are affordable compared to replacing a toilet or washing machi
