Resort Spa Showerheads from ETL

I have long been a fan of the unique showerheads made by Energy Technology Laboratories (ETL) of Modesto, California. In fact, I’ve used nothing but ETL showerheads in my home for about 15 years—and I’ve given them as gifts. Having used only 2.5 gpm (9.5 lpm) models, I recently installed first a 1.5 gpm (5.7 lpm) model and then a 2.0 gpm (7.6 lpm) model to determine how the performance differs among these products.

First some background: All of ETL’s showerheads use a patented venturi air-induction design with a single, centered orifice rather than a lot of small holes in the face of the showerhead. The water flows through stationary fins to break the stream into pulsating droplets, accelerate the water, and entrain air with the water. The end result is a precise, remarkably forceful, and satisfying spray pattern, even with relatively low flow rates. And, significantly, with the single orifice, there are no small holes that can become clogged.
