Silviri
Water damage is one of the most expensive problems in apartment buildings — and a large share of the cost often falls under owner's deductible. Silviri helps you catch leaks early, alert the right people, and shut off water when needed — before damage spreads to the unit below. No resident WiFi. No complicated new system for your team.
Most multifamily water damage comes from small, ordinary failures that go unnoticed for hours, not from dramatic pipe bursts. Below are four of the most common loss scenarios in 50–300 unit buildings, with typical cost ranges and how early detection changes the outcome.
A small connector under a unit's toilet fails. Water runs continuously into the bathroom, the hallway, the unit below. Nobody knows until 6am.
Typical bill: $25K–$60K. Plus tenant relocation. Plus a bigger premium next year.
Sensor under the toilet detects water in seconds and alerts your team. With shutoff configured, water stops in minutes.
Often: a few hundred dollars instead of tens of thousands. Damage stays in the bathroom, not the units below.
A tenant draws a bath, falls asleep, tub overflows for 90 minutes. Water cascades through the floor — light fixtures, electrical, drywall, flooring below.
Typical bill: $40K–$100K. Two units uninhabitable. Likely habitability complaint.
A floor sensor sees standing water within seconds and alerts your team. Shutoff — assisted or automatic — can close the water before it reaches the ceiling below.
Often: localized to one bathroom instead of two units. Dried out in a day, not weeks.
A water heater in a hallway closet ruptures slowly Friday night. Nobody walks past. By Monday, water has soaked into the wall, into a vacant unit, into the unit below.
Typical bill: $15K–$40K. Plus mold remediation. Plus weeks of lost rent.
Sensor in the drip pan triggers as soon as water touches it. The water heater valve closes — automatically if that mode is on, or with one tap from your on-call staff.
Often: limited to replacing the water heater. Damage rarely escapes the closet.
A supply line behind a wall in an empty unit fails. No tenant to notice. Property manager doesn't check the unit for 8 days.
Typical bill: $80K–$200K. Multi-unit damage. Major insurance event. Lawsuit risk from affected residents.
Sensors in vacant units work the same as occupied ones. The leak gets caught immediately, before nobody-noticing turns into nobody-checking-for-a-week.
Often: a wall repair instead of a major claim. The unit your tenant never knew was leaking.
Outcomes depend on detection timing, sensor placement, shutoff configuration, and your building. The numbers above show typical cost ranges from industry loss data and what early detection can achieve in a properly scoped deployment — not a guaranteed result for every event. Note that slow leaks and maintenance-related water damage are commonly excluded from standard multifamily policies [3], which means even insured owners absorb that loss class out of pocket. This is exactly the category Silviri's flow-meter tier is designed to surface.
Three steps, in order. The system operates in the background; your team only interacts with it when an event needs attention.
Small wireless sensors at the places water actually fails — toilets, sinks, washers, water heaters, AC drip pans, exposed risers. They run on a battery for 5+ years. No new wiring, no outlets.
When a sensor confirms a leak, Silviri alerts your team and can shut off the water automatically once that mode is enabled. Most buildings start in assisted mode (we recommend, your staff approves) and switch to automatic once AI adapts to your building. Protect tier+

Federal Reserve research published in 2025 found that multifamily property insurance costs rose more than 75% in real terms from 2019 to 2024 — from $39 to $68 per unit per month nationally [1]. In Los Angeles specifically, multifamily insurance now runs around $1,000 to $1,160 per unit per year, growing 30%+ year over year [2].
Here's the part that should worry every owner: only 25 to 28 cents of each dollar of insurance increase passes through to tenants in renewal rents. The remaining 72 to 75 cents falls directly on the owner's net operating income [1]. You can't just pass insurance through. You have to reduce the underlying claim frequency — or your NOI keeps eroding.
Water damage is the #1 claim category driving those increases [3]. And many slow leaks are excluded from standard multifamily coverage entirely [3] — meaning even insured owners absorb that loss class out of pocket.
Silviri is built to catch leaks early enough that they don't become deductible-bearing claims — and to surface the slow ones your policy won't cover anyway.
All apartment buildings can benefit from Silviri's leak-detection and damage-reduction system. However, older buildings typically experience higher leak frequency due to aging plumbing, fixtures, and infrastructure, which often makes the potential savings from early detection and damage reduction even greater.
At the same time, water damage is not limited to older properties. Even brand-new buildings experience leak events caused by human error or installation failures — such as a bathtub left running, a loose appliance connection, or a failed water-supply line. These incidents can still lead to significant damage, tenant disruption, and insurance claims.
Larger buildings also tend to benefit more from leak-detection systems because the probability of water-related incidents increases with the number of units, fixtures, appliances, and occupants. In multifamily properties, a single leak can spread across multiple units, increasing repair costs, operational disruption, and deductible exposure.
Detect alerts your team to leaks. Protect adds remotely controlled shutoff. Optimize adds flow meters for detecting events not accessible by leak detectors and AI to automate the protection. Each tier builds on the one before it.
Sensors at accessible high-risk leak points. Real-time phones and emails to you and the unit tenants. No plumbing changes.
Everything in Detect, plus an automatic shutoff valve. When a leak is confirmed, the water can close — either with a one-tap approval from your on-call staff (assisted mode) or automatically (once you turn that mode on). Damage stays contained instead of cascading into the units below.
Everything in Protect, plus flow meters. Catch slow drips and pipe bursts that leak sensors cannot see.
If flow meters are installed for each unit, submetering service can also be enabled. Per-unit water-consumption data can be used for tenant billing and usage monitoring.
Within each tier, sensor and shutoff coverage scales to your building's risk and budget. We'll figure out the right setup with you during the assessment — there's no one-size-fits-all answer for a 50-unit garden-style vs a 300-unit mid-rise. Tap each level below to see what's included.
These are the questions property managers and owners ask most often during initial conversations.
No. Silviri runs on its own private wireless network across your whole building. Tenants don't install anything, configure anything, or even know it's there. There's no resident app, no QR codes on move-in, no support tickets from someone who can't get the app to work.
By default, nothing automatic. The system texts your on-call staff with what it saw and where. They tap "ignore" or "shut off." False alarms become a five-second tap, not a flood. Most owners run in this "we recommend, you approve" mode for the first 90 days — long enough to trust the system before letting it close valves on its own.
Your on-call person gets a text and an email at the same moment, identifying the building, the unit, the specific sensor, and what it saw. They open the dashboard from their phone (no app to install — it's a web link). They see the alert with one of three confidence levels: critical, warning, or advisory. For critical: a "shut off zone" button is one tap away, no driving required. For warning or advisory: they assess and decide whether to drive over. The flow is designed to be completed in seconds from a phone — without needing to be at the building.
Only if you turn that mode on, and only after you've trusted it for a while. The default is "we detect, you decide." Automatic shutoff is an opt-in setting most owners enable on their second or third building — not their first.
Your own licensed plumber. Your existing trusted maintenance team or your trusted plumber follows our published install specs.
The local hardware keeps working. Sensors still detect, the gateway still receives, and the shutoff valve still closes — all on local logic. Internet is for the dashboard view and for sending texts to you. The protection layer doesn't depend on the cloud being reachable. The system fails safe; it never fails open.
No. The dashboard works like any web app: list of buildings, list of events, click for details. We do a 30-minute onboarding call when the system goes live and leave a one-page reference card in your office. That's the entire training program.
Yes. We strongly recommend it. The standard engagement is a 90-day pilot on one building — you see the actual savings on real numbers before you commit to the rest of your portfolio. If it doesn't work out, we walk away. No long contract, no cancellation fee, no awkward unwinding.
Five fields, no email required. The output is a directional estimate of typical-year out-of-pocket avoidance. A building-specific number requires actual deductible, claim history, and plumbing details — those are covered in the 30-minute call.

Schedule the 30-minute callSilviri is based in Irvine, California. We work directly with the buildings we deploy in. The team has a background in wireless engineering and chose multifamily water damage as a focused application.
Every design choice — radio selection, dashboard event triage, valve installation procedure — was made specifically for 50 to 300 unit multifamily, not adapted from a consumer leak detector.
Share a few details about your building and we'll review the numbers in a 30-minute call. If the savings math doesn't work for your specific situation, we'll say so.
