Title: Cost efficient? Yes!
Review: Good deal for the cost of having 5 filtrations systems. And the taste was unbelievable. It took the plumber a little over an hour and another tube to install it. That brought his bill very close to the cost of the unit. This is not a complaint about the unit, just plumber rates. I checked several units, even spoke with someone who sold them and we both agreed the quality and price were unbeatable. Thank you again, Amazon.
