Contents of Reverse Osmosis (RO) System
Note: Reverse Osmosis water should not be run through copper tubing as the purity of the water
will leach copper and cause an objectionable taste in water and may cause damage to copper
tubing. Watts supplies specialty medias that can be used if copper tubing is down stream of
the RO. Be sure to follow any state or local regulations.
Operational Parameters
Note: The operating pressure in your home should be tested over a 24 hour period to attain the
maximum pressure. If incoming pressure is above 85 psi a pressure regulator is recommended and
if over 100 psi then a pressure regulator is required.
