The retained reference is $389.00 current U.S. direct-store reference. Confirm 3/4 or 1-inch CTS material, five inches of straight pipe, temperature range, outlet and Wi-Fi before purchase. 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 3/4 or 1-inch CTS material, five inches of straight pipe, temperature range, outlet and Wi-Fi before purchase. Confirm current stock, seller authorization, tax, delivery, fittings, valves, sensors, hubs, backup power, subscription, labor, permits and return terms before paying.
Monitor fits a supported copper, PEX or CPVC main when a meter-mounted sensor will not work and the buyer accepts AC power, calibration and alert-only response.

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.
Monitor 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 pipe compatibility, contact-pad calibration, app, integrations, support and false flow 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.Monitor-family owners discuss calibration, app behavior, integrations and support. Small self-selected reports cannot quantify accuracy or uptime.
Compare readings with a measured fixture flow and retest after any pipe or sensor movement, while keeping a direct human shutoff plan.

StreamLabs identifies Monitor as a powered clamp-on ultrasonic sensor that reads main-line flow without a pipe cut and sends app leak and temperature alerts.

The ultrasonic clamp supports specified 3/4 and 1-inch CTS copper M or L, PEX and CPVC with a stated 0.25 GPM threshold under conditions, 0.5 GPM on copper L; it has no valve or direct floor-water sensor Monitor supplies Manual, Away and Smart alerts but cannot close water; response depends on notification delivery and a person or separately designed actuator The pipe must be compatible, clean, straight and within indoor environmental limits, and the sensor must not be twisted after pad contact; monitoring does not change backflow, permit, freeze or manual-main requirements
Its 5.9 V supply needs 100 to 240 VAC within cable range and there is no internal outage battery; lost AC removes monitoring 2.4 GHz Wi-Fi, app, account and cloud supply flow history and alerts, and StreamPlus service levels may alter analytics; household usage, temperature and account data retain privacy and service-continuity boundaries Check calibration against known flow, preserve contact pads, inspect power and Wi-Fi and review alerts; pipe age, material, air, pad damage, cloud loss and alert-only response 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 laboratory-style testing compares sensing architecture, flow thresholds, shutoff capability, installation, power, connection and subscription boundaries. Results are configuration-specific and do not prove future detection or damage prevention.
Monitor-family owners discuss calibration, app behavior, integrations and support. Small self-selected reports cannot quantify accuracy or uptime.
Flume 2 Smart Home Water Monitor is the whole-home alert-only monitoring alternative at $269.00 current U.S. direct reference.
Smart Water Assistant is the whole-home alert-only monitoring alternative at $299.99 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.
