The following appeared in a letter from the owner of the Sunnyside Towers apartment complex to its manager."One month ago, all the showerheads in the first three buildings of the Sunnyside Towers complex were modified to restrict maximum water flow to one

In this argument, the author expects that modified showerheads applied throughout all twelve buildings in Sunnyside Towers complex can dramatically increase their profits by restricting water water flow. This conclusion is based on the efficiency of using such showerheads in the first three buildings, the prediction of a considerable savings for Sunnyside Corporation, which pays for water each month and the preclusion of any problem because of almost no problems with showers reported. Whereas, lacking in cogent evidence, the validity of the author’s expectation is severely undermined.

As is mentioned by the author, the first three buildings have successfully modified all their showerheads to restrict maximum water flow. He apparently acquiesce in the authenticity of the measure if applied in the other buildings. Nonetheless, some possible difference between these buildings should not be neglected. For instance, water system in the other nine buildings might be incompatible of the modified showerheads so that they cannot effectively reduce maximum water flow. Therefore, the author should provide more details about the water supply system of the other buildings to ensure the practicality of applying the modified showerheads.

Even though the modified showerheads is effective in all twelve buildings, the reduction of water usage not necessarily leads to the considerable saving of Sunnyside Corporation. The author obviously assumes that less water flow generated by showerheads inevitably saves cost and brings about profits. Yet no one can deny the influence of other aspects contributing to the water usage as well as profit. For example, the pipeline system of the Sunnyside Towers complex is too obsolete to avoid extra waste, in which case, reducing water flow through showerheads cannot fundamentally decrease wastage or augment profits. Thus, we need more evidence concerning the water supply system and financial condition of Sunnyside Corporation to ensure that modifying showerheads certainly promotes its profits.

Apart from practical benefits modifying showerheads can bring to this company, the author should not rash to the assertion that the showers have no problems according to merely a few complaints reported about low water pressure since the adjustment. He clearly premises that a few reported complaints equals to a satisfying reflection of users, which appears to be unfounded. Actually, there may be a large number of users unsatisfied with the water pressure but do not bother to complain or failed to find proper ways to. In this case, several complaints can hardly indicate the real reply of users. Thereby, more general feedback or more comprehensive statistics are required to make the conclusion convincing.

Consequently, the author attempts to predict an increase in profit of Sunnyside Corporation by modifying showerheads to restrict water flow throughout all buildings in the Sunnyside Towers complex. Failing to present cogent evidence or necessary details, the reliability of this argument is undermined.
