What trick did the water sales person use today in my office?

Our Branch Manager, who does sales, was kind enough to meet with a representative (i.e., salesperson) from a company that sells systems that purify water from the tap.
After their meeting, the Branch Manager called us to the kitchen to show us the water that the sales person "tested." One cup had tested water from the tap and the other cup had tested water from our current bottled water system.
The tap water was a dark greyish color and had floating particles in it. The bottled water was light red (almost rusty) looking and also had particles in it.
Our branch manager said she ran it through a device to test the purity. This device was plugged into our work kitchen wall.
Now, what chemicals or additives did this person put in the water to show that it is supposedly impure? I'm curious as to how this trick works. A Google search provides me with a lot of warnings about duplicitous sales people for home water purification systems and little information about how this works.
I am guessing there is a chemistry trick involved here, I just want to know the exact methods. Obviously, I am advising her not to purchase the system and would like some idea of how we were duped.
