Eddy vs ZoJacks: In-house water operators, not an alarm central station.
Both detect leaks, can shut off the water and offer 24/7 monitoring. ZoJacks uses a UL-listed Five Diamond central station. Eddy's own operators call your team within minutes of an alert and stay on until the water is off.

Where Eddy and ZoJacks differ
| Feature | Eddy | ZoJacks | Why it matters |
|---|---|---|---|
| Who answers an alert | In-house operators who stay on until the water is off | A UL-listed Five Diamond alarm central station | What matters is who stays on the line. An operator who knows the building's valves and contacts can work the event until the water is off. |
| Network | Eddy's own LoRaWAN network on cellular or Ethernet gateways, no building Wi-Fi | A hub for up to 200 devices, plus range extenders | The network decides what the system can see. Leaks start in mechanical rooms, risers and concrete cores, where Wi-Fi and cellular signals often fade. |
| Record of each event | A Leak Incident Report for every confirmed event | Alert history, system health and monthly reports | At renewal, insurers ask what happened, how fast it was caught and what was done. A report for every event answers all three. |
| Sensor battery life | Primary lithium, 7 to 10 years | Up to 5 years on two AAA batteries | Battery swaps mean entering units and opening ceilings. Across hundreds of sensors, a longer life means far fewer visits. |
| Largest shutoff valve | Up to 18 inches with Eddy Link | Various plumbing sizes, largest not stated | A burst riser or main needs a valve sized for that pipe. Small valves can only isolate the lines they sit on. |
| Resident billing | Unit meters feed your submetering company | Not stated on its website | In rental and condo buildings, the unit meters that watch for leaks can also bill each unit for its own water, through your submetering company. |
| What both have | |||
| 24/7 monitoring | Eddy's monitoring center, with operators who call your team | 24/7 professional monitoring, plus app alerts | Leaks don't keep business hours. Someone has to be watching at night, on weekends and on holidays. |
| Leak sensors | Eddy H2O sensors for water, humidity and temperature | Water sensors, plus CO2, humidity and temperature sensors | Sensors where leaks start, at fixtures, fan coils and risers, find water before it spreads. |
| Automatic shutoff | Eddy IQ and Eddy Link valves, by rule or operator | WaterStop valve, closed on a leak or a schedule | Closing a valve is what stops the damage. An alert alone only reports it. |
| Installation and support | A project manager, then a Building Success Manager | Installation, plumbing, maintenance and resident training | Someone has to place the sensors, set the alert rules, test the valves and keep the call list current long after go-live. |

What happens in a leak, step by step
- A washing machine supply hose bursts in a suite upstairs.
- Eddy H2O under the washer detects water and sends the alert over LoRaWAN.
- The building's gateway relays it. Your team and the 24/7 monitoring center are alerted at the same time.
- A shutoff rule closes the suite's Eddy IQ valve. The water stops at the source.
- Within minutes, an operator calls your on-site team through the escalation protocol.
Automatic shutoff is configured per building. Some sites use operator-coordinated isolation instead.

Eddy runs one program on its own network, so most buildings switch at renewal or during a capital project. We'll review your setup and show what would change.
Eddy vs ZoJacks: common questions
Does ZoJacks have a 24/7 monitoring center?
Yes. ZoJacks offers 24/7 professional monitoring through a UL-listed Five Diamond central station. Eddy's in-house operators stay on the line until the water is off, and a Leak Incident Report follows each confirmed event.
What happens when an alert fires at 2 AM?
Where a valve is set to close on a leak, it shuts off the water first. Then an Eddy operator calls your on-call contact within minutes and stays on until it's handled. ZoJacks routes alarms to a UL-listed Five Diamond central station, plus app alerts to your team.
Does Eddy need building Wi-Fi?
No. Eddy runs its own LoRaWAN network on cellular or Ethernet gateways, so it never relies on building Wi-Fi. LoRaWAN reaches through concrete cores and mechanical rooms, with about one gateway every two floors in a tower. ZoJacks' hub connects over Ethernet, Wi-Fi or a SIM card.
Can Eddy help with our insurance?
Yes. Every confirmed event closes with a Leak Incident Report, documentation your carrier can use at renewal. Monitored buildings have documented premium savings of up to 20%, with deductible reductions of up to 80% documented at individual properties, though incentives vary by carrier and building.
Can Eddy protect a building during construction?
Yes. Eddy protects buildings from fit-out into occupancy. Sensors watch temporary risers and mechanical rooms, and valves can close a line after hours. The same hardware and monitoring center carry on after handover. PCL Construction builds with Eddy across Canada and the US.
How much does ZoJacks cost compared to Eddy?
It depends on the building's size, the level of protection and the valves it needs. ZoJacks publishes home monitoring at $15 a month or $180 a year, but no building prices. Eddy prices the hardware, the 24/7 monitoring center, project management and incident reporting as one managed service. Share their quote and we'll show what Eddy would add.
Is ZoJacks a better fit for some buildings?
Yes. For properties that want leak and CO2 sensors in one app, with a published monitoring price, ZoJacks is a strong choice. Eddy is built for buildings that need in-house operators around the clock and valves up to 18 inches.
