Moen · 900-001
Ready to buy
The retained reference is $559.00 current U.S. street reference. Confirm 900-001 rather than 900-006 or 900-002, authorized stock, straight-pipe clearance and every optional service or accessory. Commission sensing, closure, manual recovery, alarms and every configured notification before relying on the installation.
Current market
Each line carries its own check date because price, software, specifications, and product cycle do not age at the same speed.
Confirm 900-001 rather than 900-006 or 900-002, authorized stock, straight-pipe clearance and every optional service or accessory. Confirm current stock, seller authorization, tax, delivery, fittings, valves, sensors, hubs, backup power, subscription, labor, permits and return terms before paying.
Choose the 900-001 when a 3/4-inch full-port installation, trained automatic shutoff and Moen's optional sensor and service ecosystem fit better than a local-only point-sensor system.

What changed
Older observations stay in the ledger when the current view changes. That lets a buyer tell the difference between an old complaint, an active issue, and a problem that was corrected.
Flo Smart Water Monitor and Shutoff 3/4 inch was checked against manufacturer identity and support, current U.S. price, sensing and valve hardware, pipe and installation fit, power, connection and service, independent evidence and bounded owner or installer reports.
Each amount stays tied to its source and capture date. Conflicting prices remain visible until the seller resolves them.

Owner experience
Owner and installer evidence centers on plumber fit, learning and nuisance shutoffs, wi-fi changes, valve exercise and support rather than a universal detection or prevention result.
These are self-reported or retailer- and manufacturer-presented experiences across different pipes, valves, pressure, water quality, sensors, power, networks, accounts, settings, installations, maintenance and leak events. They identify commissioning and service checks and do not establish standardized sensitivity, closure time, notification delivery, runtime, reliability, failure rate, flood or freeze prevention, safety, code approval, insurance eligibility, coverage or claim outcomes.Exact-model owner reports cover plumber installation, nuisance alerts, valve operation, Wi-Fi and support over varied plumbing. Self-selected reviews do not establish detection or failure rates.
Commission the exact pipe and power installation, observe learning and test both local closure and remote notification without treating a successful test as a future guarantee.

Moen identifies 900-001 as a whole-home smart valve that learns usage, runs pressure-based microleak tests and can close the potable-water main.
$559.00 current U.S. street reference was retained for 900-001. Confirm 900-001 rather than 900-006 or 900-002, authorized stock, straight-pipe clearance and every optional service or accessory
900-001 uses in-line flow, pressure and temperature sensing around a motorized 3/4-inch NPT valve; it does not directly sense roof, drain, sump, sewer or floor water unless compatible remote detectors are separately installed Automatic shutoff depends on learned usage, Home or Away state, alert severity and the user's settings; manual device and app control remain available, while a detected anomaly can be misclassified or missed Moen recommends professional in-line installation with correct direction, pipe support, service clearance and local plumbing and electrical compliance; backflow devices, fire sprinkler branches, irrigation, wells, softeners and thermal expansion can alter placement, while the sensor is not a freeze-prevention device
The valve needs continuous low-voltage power from its AC adapter; the separately sold battery backup changes outage behavior but does not create unlimited runtime, and a manual valve path must remain accessible 2.4 GHz Wi-Fi, a Moen account, app, cloud processing and notification delivery support remote monitoring; optional FloProtect changes warranty and service terms, and household flow, pressure, fixture inference, address and account data carry privacy and account-lifecycle boundaries Exercise the shutoff, run observed leak tests, inspect power, network, valve, strainers and downstream plumbing and keep firmware and contact details current; scale, debris, a seized valve, lost power or cloud, learning errors and upstream, drain or sewer water remain failure modes
EPA guidance emphasizes finding and repairing the physical leak. Monitoring or shutoff equipment does not itself repair pipe, fixture, appliance, drain or water intrusion.
Backflow and cross-connection control are plumbing-system and public-health functions. A smart valve does not replace required devices, testing, permits or local authority decisions.
Connected-device users should review app permissions, accounts, data collection, security and deletion. A local valve function does not remove cloud-data and notification boundaries.
Flood coverage and claims depend on policy, peril, documentation and event facts. Owning a detector or automatic valve does not guarantee coverage, a discount or payment.
Independent hands-on coverage tests the current Flo architecture and reports installation, Wi-Fi, microleak-test, automatic-shutoff and fixture-inference limits.
Exact-model owner reports cover plumber installation, nuisance alerts, valve operation, Wi-Fi and support over varied plumbing. Self-selected reviews do not establish detection or failure rates.
Phyn Plus Smart Water Assistant and Shutoff 2nd Gen is the in-line whole-home automatic shutoff alternative at $579.99 current U.S. manufacturer-store reference.

Manufacturer identity, exact current U.S. price, current specification, manual or support, independent editorial, test or professional-market evidence and bounded owner or installer evidence were checked on August 18, 2026. This desk covers supported complete residential whole-home flow or pressure monitors, motorized main shutoff systems, retrofit valve controllers with a coherent sensor branch, alert-only whole-home monitors and appliance-level automatic shutoff systems. It excludes loose sensors outside a coherent supported branch, standalone valves or actuators without the required controller, unsupported marketplace hardware, irrigation-only valves, commercial-only BMS, obsolete products and cosmetic multipacks or bundles. Sensor type and placement determine what can be observed. Flow, pressure-wave, utility-meter, clamp-on ultrasonic and direct-water sensors have different thresholds and blind spots. Valve size, connection, full-port geometry, direction, straight-run needs, pressure and temperature rating, potable-water approval, meter, PRV, well, treatment, irrigation, fire branch, thermal expansion, check valve and backflow placement are site facts. Alert-only systems never stop water. Automatic systems depend on configuration, learning, detector coverage, valve operation and available power. AC, batteries, backup modules and manual overrides have separate limits, and an internet-offline claim is not an electrical-outage claim. Apps, Wi-Fi, hubs, accounts, cloud analytics, subscriptions, monitored service, notifications, firmware and integrations have privacy, security, retention, outage, ownership-transfer and provider-continuity boundaries. Use qualified plumbing and electrical work and required permits, inspections and backflow review. Isolate electrical and water energy before service. Do not touch wet energized equipment. Hot water, contaminated floodwater, sewage, sewer backup, mold, frozen pipe, roof, drain, groundwater and water already stored in an appliance or tank can remain after a valve closes. Fix the source, dry and remediate materials and use emergency, utility, plumbing, electrical, public-health and insurance guidance. Product ownership or an insurer program does not guarantee a discount, eligibility, coverage or a claim. No sensor, valve, algorithm, test, alarm, app, cloud, battery, subscription, plumber, warranty or installation guarantees leak detection, automatic closure, flood or freeze prevention, notification, runtime, reliability, service life, mold prevention, property protection, code or permit approval, insurability, coverage or an insurance outcome.
