Anyone else out there renting RO units from Culligan? I am, as is a friend
in Nogales. We both discovered the unsettling fact that our units are
producing equal amounts of waste water and product water. These things
are supposed to produce waste:pure water in about a 3:1 to 9:1 ratio.
I'm having a repair man come out this week.

What's a good, inexpensive way to test water quality? What agency or
whatever does one call?
