The Water Test Kit
To obtain an independent laboratory water test kit, please call Legend Technical Services at
1.800.949.8220, Option 4. They will contact you to find out what water tests you are interested in,
and inform you of the cost of the testing. You will then receive a kit that will include all necessary
tests to properly indicate the performance level of your system. Product water should be tested a
minimum of every six months.
NOTE: When the TDS reduction of the system falls below 75%, it is time to replace the reverse
osmosis cartridge in addition to the prefilter and postfilter.
