Can the Flo by Moen Smart Water Shutoff be installed on any type of water supply line?


The Flo by Moen Smart Water Shutoff is designed for use on potable water service lines such as copper, PEX and PVC. The Smart Water 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 Smart Water 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 by Moen Smart Water Shutoff.  

We also recommend the installation of the Flo by Moen Smart Water Shutoff to be after (downstream) the well pump (pressurization), filtration, and the water storage tank. 

Please contact Flo Support or call 844-Meet-Flo if you have any questions.
