We received a reviewer comment saying since we had an adjustable shower head we would have to assume the highest gpm setting. We'd like to appeal the credit and ask that the gpm of the 3 shower head setting be averaged to determine the gpm as is done with the dual flush toilettes. It seems a bit rash to assume that everyone will re-adjust the shower head to the highest setting. It would be like assuming that everyone uses the higher flush option on the dual flush toilets.

Has anyone had any issues with adjustable shower heads?
