Product Identity

The Watts SS009M3QT is a reduced-pressure-zone backflow preventer designed for plumbing systems that require protection against back-siphonage and back-pressure. It serves contractors and facility managers who need a code-compliant device for potable-water lines.

Critical Specification

The unit operates from 33 to 180 F and withstands a maximum pressure of 175 PSI, with a 1/2-inch NPT connection and stainless-steel construction. These limits determine whether the valve matches the temperature, pressure and pipe-size requirements of the installation.

Bundled Impact

The quarter-turn test cocks simplify field testing and maintenance without extra tools, while the USC listing confirms the assembly meets the University of Southern California standard for backflow prevention. No additional accessories or software are included.

Questions about this item

What does the 175 PSI rating mean when the backflow preventer is installed in a plumbing system?

It indicates the maximum working pressure the device can handle continuously; the system pressure must stay at or below 175 PSI to avoid damage.

How does the NPT connection standard limit what pipe or fittings can be used with this 1/2 inch backflow preventer?

The 1/2 inch NPT threads require matching NPT male or female fittings; other thread types such as BSPT will not seal correctly.

What clearance is needed to fit the 10 inch long stainless steel body with quarter-turn test cocks into a piping run?

Allow at least 10 inches of straight pipe run plus extra space for the quarter-turn test cock handles to operate freely.
