Why New York buildings carry water risk

More than half of New York's housing units sit in buildings constructed before 1947, and in Brooklyn nearly half of all units predate 1940. Older buildings were usually plumbed with galvanized steel, which rusts and scales from the inside until mains and risers start to leak. Many buildings above about six stories also feed those risers from a rooftop tank that a pump refills as it drains. When a riser fails high in the stack, the water runs down through every apartment below it.

The new stock carries different risk, not less. New York completed more new homes in 2025 than in any year in decades, most of them in buildings of 100 units or more. In 2024 the most new homes went up in Long Island City, Greenpoint, Jamaica and Downtown Brooklyn. New buildings leak too, at plumbing fixtures, toilets and air conditioning units, and in a tower one failed connection can reach the finished units below it.

Winter brings the sudden failures. The city dropped below freezing on January 24, 2026 and stayed there for more than a week. Heat rules keep occupied apartments warm, but pipes in basements and other unheated spaces are the ones most exposed to freezing. Eddy's 24/7 monitoring center in Toronto confirms every alert, calls the building's contacts through the escalation protocol within minutes of the SMS, email and app alerts and can close a valve remotely when the building's response plan calls for it.

Where leaks start in New York buildings

Galvanized risers in prewar buildings

Prewar mains and risers were usually galvanized steel, which rusts and scales from the inside for decades until a joint weeps. One Manhattan co-op replaced every riser after a single burst damaged the building from the eighth floor all the way down. Continuous monitoring catches a slow leak before it reaches the apartments below.

Rooftop tanks that refill on their own

Many buildings above about six stories feed their risers by gravity from a rooftop tank, and a pump refills the tank as it drains. A leak downstairs keeps drawing on that supply until someone finds it. Flow monitoring sees the run nobody hears, and water can shut off automatically or on a remote command.

Unheated spaces in a hard freeze

The city stayed below freezing for more than a week in late January 2026. Heat rules cover apartments, but pipes in basements and other unheated spaces can still freeze and burst. Flow monitoring flags the burst the moment water starts to move.

Claims history decides the renewal

New York co-op and condo renewals have come in anywhere from 10% to 300% higher depending on claims history, and many brokers urge boards to pay for minor repairs instead of filing. Carriers have also pushed water damage deductibles higher. A leak caught while it is small can stay out of the claims history.

Smart leak detection in New York

A smart water leak detection system pairs wireless sensors and smart meters with automatic shutoff, so a New York building catches a leak in seconds instead of discovering it from a ceiling stain. Eddy runs the full stack as one managed program with a staffed 24/7 monitoring center on the chain.

Sensors plus flow intelligence

3-in-1 wireless sensors watch high-risk spaces for water, temperature and humidity while smart meters flag abnormal flow against thresholds learned from the building's own baseline.

No building Wi-Fi needed

Devices run on Eddy's own LoRaWAN network at 915 MHz, a long-range radio that holds a signal through concrete. Gateways backhaul over Ethernet or LTE cellular, and with cellular backhaul monitoring stays up even if building internet goes down.

Shutoff plus a live response

Automatic valves close the moment a configured rule fires, and Eddy's monitoring center calls the building's contacts within minutes of every alert. Every confirmed event closes with a Leak Incident Report.

How Eddy works in a New York building.

In New York's dense, high-value apartments one leak can reach many units at once, and cold snaps put supply lines in exterior walls at risk. Turn the building to see where sensors, meters and valves sit, then run a leak through the system, from the first drop to the monitoring center's response.

What happens in a leak, step by step
  1. A washing machine supply hose bursts in a suite upstairs.
  2. Eddy H2O under the washer detects water and sends the alert over LoRaWAN.
  3. The building's gateway relays it. Your team and the 24/7 monitoring center are alerted at the same time.
  4. A shutoff rule closes the suite's Eddy IQ valve. The water stops at the source.
  5. An operator confirms the alert and calls your on-site team through the escalation protocol.

Automatic shutoff is configured per building. Some sites use operator-coordinated isolation instead.

Smart sensors at every leak point

Eddy places point-of-leak sensors and smart flow meters where water damage actually starts in New York buildings, from the mechanical room to a laundry hose, so a leak is caught at the source and shut off before it spreads.

NYC water billing rewards prompt leak repair

The NYC Water Board raised water and wastewater rates 6% for the year that began July 1, 2026. Metered buildings pay for water by volume plus a wastewater charge larger than the water charge itself, so a leaked gallon is billed for sewer too. Multifamily buildings on the flat per-unit Multi-family Conservation Program must promptly repair substantial leaks, and DEP can move a building to metered billing when unaddressed leaks drive use up. Documented monitoring is a record that the building finds its leaks and fixes them.

A team behind every alert

A 3 a.m. alert is one chime. Nobody is awake to hear it.

Fast response is not just the hardware. The technology sees the water in seconds, and the managed service behind it, a monitoring center that calls your team within minutes, turns that into a contained event before it becomes a claim.

Tuned by real events

Built over a decade in operating buildings.

Eddy has been inside buildings since 2014. Sensor placement, alert thresholds and the monitoring-center playbook are tuned by what real water events across our monitored properties keep teaching us.

Built for the building

Sized to how the water system behaves.

Multi-family stacks, commercial towers, hospitality suites, course-of-construction projects. Each water system has its own failure pattern. The coverage map, response chain and shutoff sequence are scoped to the property in front of us, not a template.

Detect, contain, document

Every event leads to a closed incident.

Sensors find where water escaped. Automatic shutoff isolates the affected zone. The 24/7 monitoring center calls your team within minutes and stays on it until it's closed, with a Leak Incident Report on file.

New York water leak detection FAQ

  • Do you serve all five boroughs?

    Yes. Eddy protects commercial and multifamily buildings in Manhattan, Brooklyn, Queens, the Bronx and Staten Island. It also serves the wider metro from Westchester and Long Island to Jersey City and Hoboken, and the 24/7 monitoring center in Toronto watches every building around the clock.

  • Can you retrofit an existing co-op or condo?

    Yes. Eddy layers onto the plumbing a building already has, prewar galvanized risers included, and wireless point-of-leak sensors on a LoRaWAN network install with no drywall cuts. Monitoring does not replace an aging riser, but it catches the slow leaks one produces and documents every event for the board and its insurer.

  • DEP already sends us leak alerts. Why add monitoring?

    DEP's leak notification program watches the building's water meter and sends an alert when use suddenly spikes. That tells you water is moving somewhere in the building. Eddy's point-of-leak sensors and flow monitoring show where, and water can shut off automatically or on a remote command.

  • How does monitoring fit Local Law 55 in our rental buildings?

    Local Law 55 requires owners of buildings with three or more apartments to inspect units every year for mold and pests and to correct underlying defects such as moisture. Repeat mold and leak violations can also put a building into HPD's Underlying Conditions Program, which requires the owner to find and fix the cause within four months. Catching leaks while they are small keeps them from turning into mold, violations and orders.

  • Will monitoring help our co-op or condo insurance?

    Eddy's technology is approved by most insurers across North America to provide deductible or premium savings. Programs have documented premium savings of up to 20%, and deductible reductions of up to 80% have been documented at individual properties. New York renewals swing on claims history, so a documented record of leaks caught early is worth bringing to your broker.

How Eddy works

  • What is Eddy Solutions?

    Eddy Solutions is managed water leak detection for builders, commercial asset managers and property managers, hospitals, hotels and conference centers, data centers and multifamily residential buildings across New York. It combines point-of-leak and flow sensors, automatic shutoff, building wireless connectivity, a 24/7 monitoring center and insurance-grade reporting into one program from one vendor, so a leak is detected, contained, escalated and documented without your team running the response.

    Eddy monitors 150,000+ active devices across North America and has prevented an estimated $98M (USD) in property damage last year alone. Aon's independent study found Eddy would have positively affected 58% of water-loss claims in commercial real estate.

  • How do we choose a commercial water leak detection company in New York?

    Look for five things. Sensors where leaks start, not only a meter on the main. Shutoff valves that close on their own when water runs. A staffed monitoring center that calls your team instead of only sending an app alert. Wireless coverage that holds a signal through concrete to mechanical rooms and parking levels. And a documented record of every event that your insurer can read.

    Eddy covers all five for buildings across New York, from a single tower to a full portfolio, with 150,000+ active devices in the field.

  • What happens after hours?

    The 24/7 monitoring center is the after-hours response. Trained operators confirm every alert, escalate per the building's contact list, support the on-call contact, and stay on the line until the water is off and the response is verified.

  • Will this affect our insurance?

    Yes. Eddy Solutions' technology is approved by most insurers across North America to provide deductible or premium savings. Given differences in asset types and building risk profiles, insurance incentives are not uniform. For specific insurance questions related to your property in New York, please reach out directly to sghanbarian@eddysolutions.com.

  • How is the system sized for a building, and what does it cost?

    Eddy's team walks the building, or reviews the construction drawings, and produces a tiered design matched to the asset class, water systems and insurance program. Our first step is an exploratory call with the relevant stakeholders to understand the problem you are looking to solve. Proposals come from our technical team in 7 days or less.

  • Do we have to open walls to install Eddy?

    No. Sensor installs need no drywall cuts. Wireless sensors sit where leaks start, at fixtures, appliances, fan coils and the foot of each riser, and Eddy provisions and configures the meters and valves on the lines that need them.

  • What is smart water leak detection?

    Smart water leak detection uses connected sensors and flow meters to watch a building's plumbing in real time, instead of waiting for someone to find a leak. Point-of-leak sensors catch water at the source and smart flow meters spot an abnormal run or a burst riser, and the system can shut the water off automatically or on a remote command. With Eddy, a 24/7 monitoring center acts on every alert, so detection turns into a response, not just a notification.

  • How is commercial water leak detection different from a home leak detector?

    A home leak detector is usually a single sensor that pings an app. Commercial and multifamily leak detection has to cover dozens of risers, suites and mechanical rooms, hold a signal through concrete and steel and produce the documented response insurers expect. Eddy is built for that scale, with building-grade LoRaWAN wireless, point-of-leak and flow coverage across the property, automatic shutoff up to building mains and a managed 24/7 monitoring center.

  • What is the difference between leak detection and water leak protection?

    Leak detection finds the water. Water leak protection stops the loss. Detection on its own is an alert that still needs someone to act on it. Eddy pairs detection with automatic shutoff and a 24/7 monitoring center that escalates the alert and closes the water, so the building is protected, not just alerted.

  • Does Eddy work for both multifamily and commercial buildings?

    Yes. Eddy protects multifamily and condo towers, Class A offices and mixed-use buildings, hospitality, institutional and industrial properties and active construction sites. The same managed program tunes the sensor density, shutoff strategy and reporting to how each building's water system behaves. See the full product suite at eddysolutions.com/products.
