This article includes detailed information on the Flo Smart Water Monitor and Shutoff, also known as the Flo by Moen Water Shutoff.
The Flo Smart Water Monitor and Shutoff is designed for use on potable water service lines such as copper, PEX and PVC. The Flo Smart Water Monitor and Shutoff CANNOT be installed on galvanized plumbing lines. Non-potable water sources may contain particles or debris that can adversely affect the safe operation of the Flo Smart Water Monitor and Shutoff.
When installed on well system or irrigation water service lines prior to a water filtration system, a wye strainer with a 100 mesh or finer screen and blow-down port is required to catch any sediment or particles from ground source or casing. The reason for this change is that cartridge filter housing failures are statistically significant in residential claims. The mesh screen in the strainer may require maintenance at times independent of the Flo Smart Water Monitor and Shutoff.
We also recommend the installation of the Flo Smart Water Monitor and Shutoff to be after (downstream) the well pump (pressurization), filtration, and the water storage tank.
