The following appeared in a letter from the owner of the Sunnyside Towers apartment building to its manager:

"One month ago, all the showerheads on the first five floors of Sunnyside Towers were modified to restrict the water flow to approximately 1/3 of its original force. Although actual readings of water usage before and after the adjustment are not yet available, the change will obviously result in a considerable savings for Sunnyside Corporation, since the corporation must pay for water each month. Except for a few complaints about low water pressure, no problems with showers have been reported since the adjustment. Clearly, restricting water flow throughout all the 20 floors of Sunnyside Towers will increase our profits further."

Write a response in which you discuss what specific evidence is needed to evaluate the argument and explain how the evidence would weaken or strengthen the argument.


In this letter, the owner of an apartment building concludes that low-flow showerheads should be installed in showers on all 20 floors of the building in order to increase profits. To support this conclusion, the owner cites the fact that since installing low-flow heads in showers on the bottom five floors only a few tenants have complained about low water pressure, and that no other problems with showers have been reported. However, this evidence provides little credible support for the owner's argument.





In the first place, the argument depends on the assumption that installation of low-flow heads on the first five floors has resulted in lower water costs for the owner. However, this need not be the case. It is equally possible that tenants on these floors compensate for lower flow by either taking longer showers, which would cause the overall water use to stay the same, or even increase. It is even possible that during the month since installation many of the tenants on the bottom five floors have been absent from the building. This could explain why, if it is true, that less water has been used over this brief period. And it would also explain why few tenants have complained.





In the second place, the owner ignores possible indirect consequences of installing low-flow showerheads on all 20 floors. For example, the more low-flow installations there are, the more likely that one or more tenants will become disgruntled and vacate as a result. In fact, the owner has admitted that at least a few tenants have complained about these new showerheads. High tenant turnover might very well serve to increase the owner's overall operating costs.





In the third place, in order to reasonably conclude that low-flow heads will reduce total water usage in the building the owner must assume that other water uses will remain constant in the future. However, this will not necessarily be the case. Perhaps the water supplier will raise rates, or perhaps other tenants who use more water will replace current tenants. Without ruling out such possibilities the owner cannot justifiably conclude that his total water costs will decrease after installing low-flow heads in every shower.
