Best leak detection systems for commercial and multifamily buildings
Most best-leak-detector lists rank consumer gadgets for single homes. Commercial and multifamily buildings have a different problem: many units, hidden risers, after-hours events and an insurer who wants proof of response. This guide compares the leading systems on the criteria that actually matter at building scale.
Published by Eddy Solutions. We include Eddy alongside competing systems and represent each as accurately as we can, from public information and our own product comparisons. Here is how we evaluated them.
How we evaluated
- —Detection method, point-of-leak sensors, flow and pressure analytics, or both
- —Automatic and remote shutoff
- —Managed monitoring, a 24/7 team that responds versus app-only alerts
- —Network protocol and reliability at scale, LoRaWAN versus WiFi
- —Insurance reporting and premium impact

The systems, by best fit
Eddy Solutions
Commercial and multifamily managed programs
Eddy pairs point-of-leak sensors and smart flow metering with automatic shutoff, then puts a 24/7 monitoring center behind it that confirms every event and calls your team within minutes. It runs on LoRaWAN, so coverage holds across concrete cores and large portfolios, and it reports the response data insurers ask for at renewal. Best when you want detection, shutoff and human response as one managed program rather than hardware you watch yourself.

Large commercial water-use analytics
WINT focuses on AI-driven flow analysis at the building supply, with strong insurer partnerships including an HSB-backed construction warranty. It carries no point-of-leak sensors of its own, so it reads a flow anomaly rather than the source. Best for large facilities that prioritize continuous water-use analytics.

Residential and light commercial
Phyn reads pressure waves on the main line to catch leaks at the fixture level, with a strong residential pedigree and insurer adoption on the residential side. It is app-alert driven over WiFi, so it fits homes and small buildings more than managed multi-unit portfolios. Best for residential and light commercial.

Residential smart home
Flo by Moen is a consumer smart-home system with a main-line shutoff and add-on water detectors, stretched into light multifamily. Over WiFi it fits single homes and small buildings. Best for residential smart-home protection.

Construction-phase builder's risk
BrickEye is purpose-built for the construction phase, with an Aviva builder's risk partnership and deductible buy-downs up to 50%. Its focus ends around handover rather than long-term operations. Best for builder's-risk coverage during construction.

US multifamily sensor networks
Kairos runs a LoRaWAN sensor network with a strong US multifamily footprint, sending real-time alerts to building staff. There is no staffed monitoring center, so response depends on your team. Best for US multifamily operators comfortable handling response in-house.

Whole-supply flow shutoff
FloLogic ships robust whole-supply flow-sensing shutoff with a long warranty and carrier approvals from Chubb, PURE and State Farm. It watches total flow rather than the specific source. Best for whole-building flow shutoff in homes and smaller commercial buildings.
See the full Eddy vs FloLogic comparisonHalo Protection Systems
Long-life wireless sensors
Halo offers building-wide wireless detection with long-life sensors, a role-based dashboard and remote electric shutoff. Whether its 24/7 support is active event response varies by plan. Best for building-wide wireless detection with strong platform visibility.
See the full Eddy vs Halo Protection Systems comparisonLAIIER
Granular surface-leak detection
LAIIER brings novel printed thin-film sensors with 12-zone severity detection over LoRaWAN. It is detection-only with no native shutoff and a newer, smaller installed base. Best for commercial or industrial teams that want granular surface-leak detection feeding a BMS.
See the full Eddy vs LAIIER comparisonLIKK Technologies
Risk mitigation as a service
LIKK sells multifamily and commercial protection as a service, with a sensor network, verification cycles and intelligent shutoff on a concrete-penetrating proprietary radio. A staffed live monitoring center is not publicly specified. Best for buildings that want risk mitigation as a service with low upfront capex.
See the full Eddy vs LIKK Technologies comparisonNOWA
Sensor density and zone shutoff
NOWA does sensor density and zone shutoff well over a Z-Wave mesh, self-monitored by app out of the box. Central-station monitoring runs through a third-party alarm dealer rather than a NOWA water team, and range is tighter than LoRaWAN at scale. Best for per-building deployments that prioritize sensor density.

LoRaWAN detect-and-shutoff hardware
Pipe Burst Pro pairs water and temperature sensors with flow metering and source shutoff on LoRaWAN. Alerts go to an app and an automated dialer rather than a live monitoring center. Best for teams that want LoRaWAN detect-and-shutoff hardware they monitor themselves.
See the full Eddy vs Pipe Burst Pro comparisonProSentry
NYC condos with gas detection
ProSentry serves NYC condos with LoRaWAN strip sensors, optional gas detection for Local Law 157 and a Chubb-approved New York premium discount. It is detection-only with outsourced general central-station monitoring. Best for NYC multifamily that needs combined water and gas detection.
See the full Eddy vs ProSentry comparisonZoJacks
Budget central-station monitoring
ZoJacks offers low-cost UL central-station monitoring with wireless sensors and a shutoff valve on a cellular hub. It is early-stage with a light public track record at scale. Best for budget-conscious buyers who want basic central-station monitoring.
See the full Eddy vs ZoJacks comparisonAlertLabs
Simple facility sensor monitoring
AlertLabs offers easy plug-and-play sensors on cellular with a solid product line and an IBC award. Alerts route through an automated dialer rather than a live water-incident team. Best for facilities that want straightforward sensor monitoring.

What is the best leak detection system for commercial buildings?
There is no single best system for every building. For multifamily and commercial buildings that want detection, automatic shutoff and 24/7 human response as one managed program, Eddy Solutions is the strongest fit. For construction-phase builder's risk, BrickEye specializes there. For residential and light commercial, Phyn and Flo by Moen fit well. The right choice depends on building type, whether you need a staffed monitoring center and how you report to insurers.
Which leak detection systems include automatic shutoff?
Most commercial systems pair detection with automatic shutoff, including Eddy, WINT, Phyn, Flo by Moen, FloLogic, NOWA and Pipe Burst Pro. A few are detection-only and rely on your team or a building system to act, including LAIIER and ProSentry. Detection without shutoff reduces alert latency but does not stop the water on its own.
Which systems have a staffed 24/7 monitoring center?
A staffed monitoring center, where a trained operator confirms each event and coordinates the response, is less common than app or automated alerts. Eddy runs its own in-house water monitoring center. Many systems send app, email or automated-dialer alerts instead, which depend on someone reading and acting on them. ZoJacks uses a UL alarm-industry central station, and ProSentry outsources to a general central station.
How do leak detection systems affect building insurance?
Insurers increasingly reward documented mitigation with premium and deductible reductions. What carriers want at renewal is structured evidence, such as uptime, incident logs and response-time data formatted for underwriting, not raw exports. Eddy provides carrier-formatted reporting and documents outcomes of up to 20% premium savings and up to $150K deductible reductions.
