• It may take several hours to completely fill the
tank and fully pressurize the system. Make sure to
check for leaks when fully pressurized.
NOTE: The blended water tubing/piping and associated
fittings connecting the RO blended water outlet to
the equipment being serviced should be food-grade
material that meets NSF® Standard 51, 61, or similar,
with a minimum pressure rating of 100 psi (6.9 bar,
0.69 MPa). The RO/blended water may react with
metal piping, creating a corrosive condition in addition
to imparting an objectionable taste. Plastic pipe or
reinforced beverage tubing are generally very good
material choices for RO water distribution piping. The
size of the blended water tubing/piping should be
1/2-inch (12.7 mm) O.D. minimum.
