RO Filters and Tubing
A water softener is being installed on our well water system. We had our well water thoroughly analyzed by a state certified lab and the county board of health. We have applied the much appreciated recommendations we received from this site.
Part of the system is a new RO unit at the kitchen sink. It works fine, but I have just read that because RO water is so clean it can be very aggressive, thus plastic tubing should be installed. The pro plumbers who installed the RO system ran a 1/4" copper line a little over 30' long, from the RO filter's under sink storage tank, around the kitchen perimeter to the refrigerator for it's ice maker and cold water dispenser.
Is the copper tubing a problem? Do we need to test the water at the refrigerator to see if it has excessive copper, or other contaminants, from that copper line? Do we need to have the plumbers replace that copper line with plastic tubing?
Any and all replies are gratefully appreciated and hoped for.
