Why London buildings carry water risk

London has spent the past decade flipping from a low-rise city to a high-rise one. Purpose-built rental construction set a record in 2024 and broke it again in 2025, with new towers rising downtown and across the south and southwest of the city. Every one of those buildings stacks plumbing risers behind the drywall, and when a line fails on an upper floor the water runs down through every floor below.

London sits in the Lake Huron snowbelt, where squalls arrive with long stretches below freezing and the building's own supply lines burst in exterior walls, unheated stairwells and mechanical rooms. Buildings built or renovated between 1995 and 2007 can also carry Kitec plumbing, whose corroding fittings failed often enough to trigger a recall and a North American class action.

A slow Kitec fitting leak can run for weeks behind a wall before anyone sees a stain, which is exactly the kind of failure continuous monitoring is built to catch. Eddy is headquartered in Toronto, two hours up the 401, and the same managed program protects London's new rental towers, established condo corporations, student housing near Western and Fanshawe and commercial buildings across the city.

Where leaks start in London buildings

Freeze and burst pipes

Snow squalls off Lake Huron come with long stretches below freezing. Supply lines in exterior walls and unheated areas can burst overnight and flood multiple floors before anyone notices.

New plumbing under load

Back-to-back record years of apartment construction mean a lot of new, untested plumbing. Monitoring from day one catches the early fitting and supply-line failures that follow a building into occupancy.

Kitec and aging supply lines

London buildings from the Kitec era face corroding fittings that insurers now scrutinize at renewal. Those slow leaks are the hardest to spot by eye and the easiest for continuous monitoring to catch.

Rising insurance costs

Ontario condo corporations have faced steep premium increases and higher deductibles tied to repeat water claims. Documented monitoring helps reverse that trend.

Smart leak detection in London

A smart water leak detection system pairs wireless sensors and smart meters with automatic shutoff, so a London 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.

Point-of-leak

Flow-based

More about Detect

Eddy detects water through two layers running in parallel. Point-of-leak sensors sit where leaks happen: common areas and mechanical rooms (including elevator pits), inside suites at high-risk appliances, and behind walls at the risers that hide damage until cascade. Flow-based detection runs continuously at meters across the building, flagging continuous low flow, continuous use and extreme use against thresholds learned from your building's baseline.

  • 3-in-1 sensors detect water, temperature and humidity
  • Three flow thresholds, learned per building, not generic defaults
  • Sensors are permitted near sprinkler infrastructure; valves are not

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.

More about Respond

Eddy's 24/7 monitoring center confirms every alert, escalates per your contact list and stays on the line until the water is off and the on-site team has eyes on it.

  • Configurable automation rules per zone and time of day
  • Trained operators on duty 24/7
  • Escalation: automation → property manager → emergency contact, on your list
  • Submetering and consumption data for billing, conservation and ESG reporting

More about Detect

The best time to place a sensor behind a wall is before the wall closes. Eddy goes in during construction to install the same operational-grade detection your building will run on for the next decade: sensors at common areas and mechanical rooms, concealed sensors at risers and HVAC sources you'll never be able to retrofit this easily again, plus construction-specific coverage at active high-risk zones, ambient climate monitoring during temperature and humidity swings, and optional fire main flow monitoring for unintended sprinkler discharge.

  • Same 3-bucket sensor placement as operational buildings (common · in-suite · concealed)
  • Riser and HVAC sensors placed pre-drywall, no later retrofit needed
  • Construction-only overlays: high-risk zone sensors, climate anomalies, fire main flow monitoring

More about Control

Automatic shutoff on the lines most likely to fail during construction: domestic main, temporary water supply, hydronic make-up. Schedule mode closes the valve when the trades leave and opens it when work resumes. A daily after-hours guardrail aimed at the 2 AM peak when most leaks happen and the site is empty.

  • Eddy Link + 3rd-party valve on the domestic main (sized to pipe)
  • Eddy IQ on ¾"–1" lines (temp construction water and H&C make-up)
  • Domestic zone valves added at the Unlimited tier
  • Fire mains excluded by design (monitoring permitted, see DETECT pillar)

Respond

Day 1 of the project, Day 1 of the service.

The monitoring center is on the line from the first valve install and stays on through occupancy.

3 close-ups · select one to zoom in

What happens in a leak, step by step
  1. A fitting lets go on a charged riser, several floors up.
  2. Eddy H2O on the slab detects water, and the meter on the domestic main sees the flow jump.
  3. The alert reaches the site team and the 24/7 monitoring center at the same time.
  4. The domestic main closes on the project's shutoff rule.
  5. An operator coordinates live with the superintendent until the crew has eyes on it.

Shutoff rules are set per project, per zone and per time of day.

More about Respond

Eddy's monitoring center is on the line from the first valve install. Every alert is confirmed by a trained operator and coordinated live with the superintendent, not left on voicemail. When the building reaches occupancy, the service continues with the same team. No handoff to figure out, no system to redeploy.

  • Operators coordinate live with on-site superintendent
  • Same monitoring center carries through to occupancy

Smart sensors at every leak point

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

Detect fast, act fast

Every minute changes the bill.

A leak gets bigger the longer it runs. Eddy detects in seconds and the monitoring center escalates within minutes, so the same failure is contained around minute two. Unmonitored, an after-hours leak runs six to eight hours before anyone arrives.

Reserve funds under Ontario's Condominium Act

Ontario requires every condo corporation to keep a reserve fund and update its reserve fund study at least every three years, with a funding plan proposed after each study. One major water loss can drain budgets and trigger special assessments no study planned for. Documented 24/7 monitoring keeps small failures small and gives the board a clear record that water systems are actively managed.

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.

Monitored from Toronto, close to London

Eddy protects condo towers, commercial buildings and full portfolios across North America, with 150,000+ devices watched from its Toronto monitoring center. For London buildings that means the team behind the program is two hours away, and escalation and shutoff are handled around the clock the same way they are for the GTA's tallest towers.
