Sample Installation
A. Source water from Feed Water Adapter → B. Source water to 1
st
stage water inlet
C. Wastewater from Flow Restrictor → D. Wastewater to Drain Saddle/drain pipe
E. RO water from stage 5 "T" fitting → F. RO water to Storage Tank
F. When the drinking faucet is opened, RO water from the tank passes through E and G → H. RO
water to the drinking faucet
*Note: the diagram represents a faucet with non-air gap installation. There is one valve present on
the pure water line, and the flow restrictor doubles as a one-way valve preventing drain water from
entering back into the system.
Installation Steps
Before you begin the installation, it is highly recommended to watch the video
"iSpring Reverse Osmosis Installation" on YouTube.
Note: If you plan on mounting/hanging the system, it is highly recommended to
include supports under each of the bottom three housings. Supports under the
housings will take the water weight off the housing threads and ensure the thread
strength does not decay over the years.
Note: The booster pump (and UV stage if applicable) should remain unplugged until directed.
Note: Steps 1 – 7 are independent and can be performed in any order.
