The retained reference is $286.72 current U.S. street reference. Confirm V4 dual 90-degree hose-thread valves rather than straight or single-valve versions and inspect or replace aging washer hoses separately. 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 V4 dual 90-degree hose-thread valves rather than straight or single-valve versions and inspect or replace aging washer hoses separately. Confirm current stock, seller authorization, tax, delivery, fittings, valves, sensors, hubs, backup power, subscription, labor, permits and return terms before paying.
Washing Machine FloodStop fits a conventional washer with accessible hot and cold hose taps where direct floor detection and dual closure are preferable to whole-home intervention.

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.
FloodStop Washing Machine 3/4 H90 V4 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 hose-tap fit, dual-valve actuation, sensor placement, washer drain limits and periodic testing 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 owners and installers discuss fit, wet testing, valve operation and replacement. Self-selected feedback cannot quantify avoided damage or lifetime.
Test a controlled wet trip while observing both valves and separately inspect the drain and hoses because inlet closure cannot stop every washer flood path.

OnSite PRO identifies FS3/4H90-V4 / 20010 as a local system that closes both hot and cold hose-thread supplies after its floor sensor detects water.
$286.72 current U.S. street reference was retained for FS3/4H90-V4 / 20010. Confirm V4 dual 90-degree hose-thread valves rather than straight or single-valve versions and inspect or replace aging washer hoses separately
Two 3/4-inch 90-degree hose-thread motorized valves close hot and cold supplies when the wired floor strip gets wet; it does not stop a washer tub or clogged drain from emptying and does not monitor the rest of the home Local wet detection closes both inlet valves and sounds the alarm, leaving other household supplies open; automatic closure cannot stop water already in the washer or drain system Verify hose-thread fit, valve weight and access, leak-free hoses, sensor placement and a sound drain and pan; use a plumber for damaged taps or code issues and isolate electricity before touching wet washer equipment
The controller uses its AC adapter and optional battery provision from the V4 platform; battery condition, valve cables and accessible manual supply taps remain part of the failure plan The base package is local with no cloud, subscription or app, and optional relay or third-party notification adds separate power, privacy, network and delivery boundaries Wet-test the strip, exercise both valves, inspect and replace hoses and test alarm and backup power; clogged drains, tub water, sensor gaps, seized valves and loss of power remain
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 professional-market coverage retains exact dual-valve package, manual and current availability and distinguishes washing-machine connections from water-heater systems.
Exact-model owners and installers discuss fit, wet testing, valve operation and replacement. Self-selected feedback cannot quantify avoided damage or lifetime.
FloodStop Water Heater 3/4 NPT V4 is the appliance-level automatic shutoff alternative at $202.85 current U.S. retail 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.
