Precision Flow Monitoring for Total Visibility
At the heart of Moen Flo Smart Water Monitor lies its high-resolution ultrasonic sensor, which measures water flow to within 0.1 gallons per minute. This level of precision gives you complete visibility into your home’s plumbing behavior—tracking every drip, shower, and dishwasher cycle. The sensor continually logs flow data to the cloud, allowing you to review daily, weekly, and monthly usage patterns. Unusual spikes or continuous low-flow events (indicative of a slow leak) trigger instant notifications. Unlike simple moisture detectors that only alert once water has escaped, Moen Flo lets you intercept problems at the source—before wet spots appear on your floors or walls.
Easy DIY Installation on ¾-Inch Pipes
Installing Moen Flo is straightforward for any homeowner or professional plumber. The unit clamps directly onto a standard ¾-inch copper or PEX supply line, replacing the existing shutoff valve if desired, or installed in series with a saddle valve connector. No soldering is required. Simply isolate the main water supply, attach the Flo manifold using the provided fittings, and torque to manufacturer specifications. Power is supplied via a rechargeable lithium-ion battery pack, offering up to six months of monitoring per charge. The entire setup—including Wi-Fi pairing—takes under an hour. Clear LED indicators on the manifold confirm flow status, battery health, and network connectivity.

Real-Time Leak Detection and Instant Alerts
Moen Flo’s leak detection goes beyond simple threshold triggers. Its advanced algorithms analyze minute changes in flow velocity and pressure, distinguishing between normal usage (like a toilet refill) and problematic events (such as a slab-leak or pinhole pipe breach). When the system detects a leak exceeding a user-defined duration—say, two minutes of continuous flow in an empty house—it pushes an immediate alert to your smartphone via the Moen Flo app. You’ll receive the precise location (mainline vs. branch feed), severity level, and recommended action. For multi-occupant homes, customizable alert schedules let you silence benign notifications during known usage windows.
Automatic Shutoff to Prevent Flooding
Should a severe leak or burst pipe occur, Moen Flo automatically closes its internal shutoff valve to isolate the water supply. The motorized ball valve actuates in under five seconds, sealing off flow and preventing catastrophic damage. You can configure the sensitivity: automatic shutoff can trigger on single catastrophic flow events or only after manual confirmation through the app. After shutting off, Flo logs the event and waits for your acknowledgment before attempting to restore water. This two-step process balances safety with convenience, avoiding nuisance shutoffs while ensuring serious leaks are contained immediately.

Comprehensive App Controls & Analytics
The Moen Flo app is your command center. View live flow rates, total consumption, and battery status from any location. The app’s dashboard presents intuitive graphs highlighting anomalies, average daily usage, and cost estimates based on your local water rates. Historical reports help you identify trends—like months when irrigation spikes or holiday travel reduces usage. Within settings, you can set flow thresholds, define leak-duration limits, and schedule “Vacation Mode” to heighten sensitivity while you’re away. Integration with IFTTT opens creative automations—such as flashing smart lights if a minor leak is detected or pausing a home HVAC system to signal an alert.
Compatible with Smart Home Ecosystems
Moen Flo plugs into major smart-home platforms via Google Assistant and Amazon Alexa. Ask Alexa, “What’s my water flow?” to get an instant verbal report, or request Google to “Turn off my water” in case of emergencies. For professional integrators, Flo offers an open API, enabling advanced home-automation controllers (e.g., Control4, Crestron) to incorporate water-monitoring routines. Receive SMS or email alerts via third-party services, or trigger home-security cameras to record when a leak is detected. Whether you prefer custom dashboards or voice assistants, Flo adapts to your existing setup.
Energy Efficiency and Low Maintenance
Despite its powerful features, Moen Flo is designed for low power consumption. The ultrasonic sensor and valve actuator draw minimal current, and the battery pack enters sleep mode during periods of inactivity, extending the time between charges. A full recharge takes under three hours via the included USB-C cable. The valve’s robust design—tested for over 100,000 open/close cycles—requires virtually no maintenance. Periodic self-tests run automatically to verify sensor accuracy and valve responsiveness, with any drift or fault reported through the app. With no filters or moving parts in the flow path, scaling and clogging are non-issues.

Ensuring Long-Term Reliability and Support
Built for the long haul, Moen Flo carries a two-year limited warranty and dedicated customer support. The manifold’s rugged polycarbonate housing resists corrosion, UV exposure, and freeze damage down to –20 °C. All electronic components are rated for indoor and sheltered-outdoor installations. Firmware updates—pushed over Wi-Fi—enhance leak-detection algorithms and add new app features without requiring on-site service calls. Should a component fail, Moen’s support team coordinates rapid replacements to minimize downtime. With professional-grade durability and consumer-friendly service, Flo stands as a trusted guardian for years.
Real-World Benefits and Success Stories
Homeowners report catching invisible slab leaks that had eluded detection for months—saving thousands in foundation repairs. A family on vacation received leak alerts and remotely shut off their water before a burst pipe ruined their floors. Property managers use Flo to monitor multiple units centrally, preventing tenant-caused water damage and insurance claims. Even small businesses—like cafés with espresso-machine supply lines—leverage Flo to maintain uninterrupted operations. Across all scenarios, the blend of proactive monitoring, automatic shutoff, and deep analytics transforms water management from reactive to preventative.

Comparative Advantages Over Traditional Detectors
Unlike floor-mounted leak sensors that only alert after water has pooled, Moen Flo addresses leaks at the source—inside the supply line itself. Its ultrasonic sensing provides higher sensitivity and fewer false alarms than pressure-based detectors. Whereas simple auto-shutoff valves rely on mechanical triggers, Flo’s programmable thresholds and analytics ensure shutoff only when truly necessary. Competing smart-valve solutions often require wired power or external hubs; Flo’s battery operation and direct Wi-Fi connectivity streamline installation and reduce points of failure. For comprehensive, intelligent water protection, Flo outperforms one-dimensional alternatives.

FAQ
- What pipe sizes does Flo support?
Flo is designed for standard ¾-inch supply lines—common for mains, irrigation feeds, and appliance connections. - How long does the battery last?
Typical battery life is 4–6 months per charge, depending on flow activity. Low-battery alerts appear in the app. - Can I calibrate the sensor?
Flo runs automatic self-calibration on setup. Manual recalibration is available in the app under “Device Settings.” - Will it shut off water during normal usage?
You define leak thresholds (flow rate and duration). Flo only actuates shutoff when conditions exceed those limits. - Is professional installation required?
Most DIYers can install Flo with basic tools. However, professional plumbers can integrate it seamlessly into complex systems. - Does Flo work without Wi-Fi?
It records flow data locally and actuates shutoff, but leak alerts and analytics require a 2.4 GHz Wi-Fi connection. - Can I temporarily disable auto-shutoff?
Yes—use the app’s “Vacation Mode” or disable auto-shutoff schedules while you’re home. - How do I view historical usage?
The Moen Flo app presents flow charts and usage summaries for any date range, exportable as CSV for detailed analysis.
