Daniel Dietzen has over 10 years of experience in water leak detection and building protection systems, beginning with hands-on installation and customer service work in 2015. At Halo Protection Systems, he has worked closely with engineers, property managers, owners, and installation teams to help design, deploy, and improve whole-building leak detection systems for condominium and multi-family properties.
The most common condo leak detection questions have short answers. Yes, it works when owners travel. No, it doesn't need resident Wi-Fi. Shut-off happens within seconds. Sensors live under sinks, behind toilets, and near appliances. Sensor batteries last up to 10 years; valve batteries about 5. A real person is reachable 24/7. Every event is time-stamped for insurance.

Frequently asked questions
Will leak detection work if the owner is traveling?
Yes. A building-wide system continues to monitor the unit and trigger automatic shut-off (when valves are installed) regardless of whether the owner is home, asleep, or out of the country. The 24/7 response center can also see the event and follow the building's escalation procedure.
Do residents need their own Wi-Fi for the system to work?
No. Halo runs on a dedicated building-wide LoRaWAN network with gateways placed approximately every six floors. Resident routers, internet outages, and cellular dead zones do not take protection offline.
How fast can an automatic shut-off valve close?
Within seconds of a sensor detecting moisture. The system identifies the location, opens an event record, sends alerts, and closes the mapped valves in one coordinated step.
What happens during an alert at 2 a.m.?
The system identifies the exact unit and sensor location, sends alerts to the owner and on-site staff, and (when valves are installed) closes the unit's water automatically. The Halo Response Center can also be reached by phone at any hour to confirm what happened, see live device status, and operate valves remotely after safety checks.
Can a leak detection system stop a burst pipe?
It can stop the flow. Once a sensor in the affected location detects water, the system closes the unit's shut-off valves, isolating the supply line so water stops feeding the burst.
Where exactly are sensors installed?
Under sinks (kitchen, all bathrooms, wet bars), behind toilets, near washing machines, dishwashers, refrigerators with ice makers, water heaters, HVAC equipment, and around mechanical rooms, laundry rooms, and other common areas where water is present.
How long do the batteries last?
Wireless moisture sensors can last up to 10 years on a single battery. Shut-off valve actuators typically last about 5 years. The system tracks battery levels and surfaces low-battery devices on the building dashboard before they go offline.
What if a sensor goes offline?
Device-health monitoring shows online/offline status, last check-in time, battery level, and signal strength for every device. Staff can see at a glance which units need attention without walking each one.
Will it false-alarm and shut off water for no reason?
Sensors are tuned per location — high sensitivity under sinks, more moderated in utility areas — to avoid nuisance shut-offs. The system reacts when it detects a real problem, not everyday minor moisture.
Can residents override a shut-off?
Yes. Each unit has a manual override at a wall panel. Authorized staff and the Halo Response Center can also open valves remotely after safety checks. All actions are logged in the audit trail.
How disruptive is installation?
Installation is wireless and battery-powered, so walls don't need to be opened and power cables don't need to be run throughout the building. Typical Halo install pace is about 20 minutes per residence at 30–40 residences per day.
Can a board start with just some units or floors?
Yes. Boards often start with high-risk areas — top floors, common areas, mechanical rooms, units with traveling owners — and expand coverage over time on the same shared platform.
What about HVAC closed-loop systems?
Halo's shut-off valve system supports multiple valves per residence. At The Grand in Sandestin, FL, some residences require three to six valves, including dedicated valves for HVAC closed-loop systems.
Does the system catch slow, hidden leaks?
Sensors catch moisture wherever they are placed. Optional water flow meters can also identify abnormal water usage patterns — a fixture running continuously, a hidden pipe leak, supply-side issues. At One Water Place, Halo identified a construction defect wasting an estimated 1.2 million gallons of water per year.
Who can see what in the platform?
Owners see only their own residence, including device status and valve status. Staff and management see all residences and common areas per the governing documents. Every action — view, override, valve change — is logged with a timestamp.
How do we use the data for insurance?
Every event is time-stamped: sensor trigger, valve action, alerts sent, user steps. The platform can export incident summaries and monthly Risk & Readiness reports as one-click PDFs for the carrier and the board.
What happens when a unit changes hands?
The building-wide system persists. Halo and its dealers can revisit the unit when ownership changes or after a renovation so coverage matches the unit's current reality (new appliances, moved fixtures, reconfigured rooms).
Do owners have to do anything day-to-day?
No. The system runs in the background. If something needs attention, owners receive alerts through their chosen channels (text, email, app). There is nothing to check daily.
Is leak detection only for new construction?
No. The system is designed as a retrofit-friendly install for existing condominium buildings. Wireless sensors and battery-powered valves avoid the need to open walls or run new electrical throughout the building.
How much damage can a single condo water leak cause?
The cost of a leak is often driven by how long it goes unnoticed. In condominiums, water does not always stay in one unit — late discovery can affect multiple homes and common areas, driving up repair and remediation costs and putting pressure on community budgets.
Aren't individual owner leak detectors enough?
Owner-by-owner devices leave gaps: coverage is inconsistent, alerts may not reach building staff, event history is limited, and it's hard to know which devices are offline. The issue is not whether some owners are protected — it's whether the building has one consistent standard for visibility, alerts, and action.
Who installs a building-wide leak detection system?
Halo technicians install the network equipment, sensors, hubs, and controllers, then test, label, and commission everything in the Halo Portal. Where shutoff valves are included, a licensed plumbing contractor performs the pipe tie-in, including permits and inspections, and Halo connects and tests the valve electronics.
How long does installation take in an occupied building?
Installation follows a planned sequence: network setup first, then in-unit device installation floor by floor, valve tie-ins, commissioning, and staff training. As an illustration, a 200-unit building can be modeled at roughly nine business days of on-site work, with resident notices going out in advance.
Does a building leak detection system help with insurance?
Earlier detection and automatic shutoff reduce the severity of water damage, and documented event history gives boards records to share with insurers. Halo can substantially reduce water damage and may help lower association and owner insurance premiums.
