Before you get started.
Before any pipe is cut, make sure your system meets
the installation requirements:
Installation site must be within 300 feet of an
installed Rachio 3 Smart Sprinkler Controller.
Backflow preventer and installation area must
be above ground (recommended).
Below ground installation requires additional steps
not included in this manual. For more information,
visit rachio.com/flow-underground.
The Flow Meter is not rated for potable water and
must be installed after the backflow preventer.
System must have ¾ inch or 1 inch pipe made
of either copper, PVC, PEX, or SDR9 poly.
For 1 inch PVC pipe, 1 inch copper or poly pipe,
and ¾ inch PVC pipe, you will need 14 inches of
straight pipe between the backflow preventer and
valve box.
For ¾ inch copper or poly pipe, you will need
16 inches of straight pipe between the backflow
preventer and valve box.
If you have more than one Rachio 3 controller
or more than one backflow preventer, visit
rachio.com/flow-advanced.
