Are there ways to measure the efficacy of this system ie: actually test the water hardness after the system is installed? It seems like sleight-of-hand to just wrap a magnet or whatever is going around the house water input and “believing” that it is actually working.
Well, the proof is in the pudding. Seemed like it worked for us, but, I'd put that question to the EasyWater people. They're pretty well researched over there and I'm sure could point you to their data.
