Reverse Osmosis Water Supply
IMPORTANT : The pressure of the water supply
coming out of a reverse osmosis system going to
the water inlet valve of the refrigerator needs to be
between 35 and 120 psi (241 and 827 kPa).
If a reverse osmosis water filtration system is
connected to your cold water supply, the water
pressure to the reverse osmosis system needs to be a
minimum of 40 to 60 psi (276 to 414 kPa.)
If the water pressure to the reverse osmosis system is
less than 40 to 60 psi (276 to 414 kPa):
Check to see whether the sediment filter in the
reverse osmosis system is blocked. Replace the
filter if necessary.
Allow the storage tank on the reverse osmosis
system to refill after heavy usage.
If your refrigerator has a water filter, it may
further reduce the water pressure when used
in conjunction with a reverse osmosis system.
Remove the water filter.
If you have questions about your water pressure, call a
licensed, qualified plumber.
