Mounting Your Flowmatic Housings

- Position the Watts FM100SS bracket at desired height, ensuring level alignment and adequate clearance below for filter cartridge removal
- Secure bracket to wall using appropriate fasteners for your wall type (concrete anchors, wood lag bolts, or steel stud hardware)
- Mount both Flowmatic filter housings onto the bracket, ensuring housing mounting points are fully seated and secure
COMPATIBILITY
Works With These Watts Housings
The FM100SS double mounting bracket is specifically designed for Watts Flowmatic 4500 and 8000 series commercial filter housings. These are larger commercial-grade housings typically used in restaurants, light industrial applications, and high-flow residential installations. The bracket will not fit standard residential 10-inch or 20-inch slim housings. Confirm your housing series before ordering to ensure proper fit.
🔧 Pro tip: When mounting the FM100SS, install it high enough that you can fully remove filter cartridges without kneeling, but low enough to reach the housing sumps comfortably. A bowl height of 48-54 inches from the floor works well for most installations and keeps plumbing connections accessible.
