Smart Water Shutoff Valves: 24/7 Leak Protection for Your Home

Water damage is the number one homeowner’s insurance claim in America. A smart water shutoff valve monitors your plumbing around the clock and automatically shuts off the water if a leak is detected — even when you’re not home.

PEACE OF MIND

Why Homeowners Choose Smart Valves

Water damage is the most common and one of the most expensive homeowner’s insurance claims in the country. The average water damage claim costs over $12,000 — and that doesn’t account for the personal belongings, irreplaceable items, and weeks of disruption that come with it. A smart water shutoff valve is the single most effective way to prevent that scenario.

Beyond disaster prevention, a smart valve gives you visibility into your home’s water usage you’ve never had before. You’ll know exactly how much water your household uses, spot inefficiencies, and catch small problems — like a running toilet or a dripping outdoor faucet — before they become expensive ones. Many homeowners also see a discount on their insurance premiums after installation, since insurers recognize the reduced risk.

Whether you’re protecting a home you’ve lived in for decades or a new investment property, a smart valve is an upgrade that pays for itself — in savings, in peace of mind, and in the disasters you’ll never have to deal with.

HOW IT WORKS

How a Smart Water Shutoff Valve Protects Your Home

A smart valve replaces your main water shutoff valve and adds intelligence to your plumbing system. Here’s what happens behind the scenes to keep your home safe.

01

Continuous Monitoring

The valve’s sensors monitor water flow, pressure, and temperature 24 hours a day, 7 days a week. It tracks every gallon that passes through your main line — even while you sleep.

02

Learns Your Home

Over the first few weeks, the system learns your household’s normal water usage patterns — when you shower, run the dishwasher, water the lawn. It builds a baseline of what “normal” looks like for your home specifically.

03

Detects Anomalies

When something doesn’t match your home’s pattern — like continuous flow at 2 a.m. or a sudden pressure drop — the system flags it immediately. Some systems, like Moen Flo, run daily micro-leak tests that pressurize the system to detect even the smallest leaks.

04

Automatic Shutoff

If a potential leak is confirmed, the valve automatically shuts off the water supply to your entire home — stopping the damage before it starts. No human intervention needed. It works whether you’re home, at work, or on vacation.

05

Instant Alerts

The moment the system detects an issue or shuts off the water, you get a notification on your phone. You can also manually open or close the valve from anywhere in the world using the app.

WHAT IT PROTECTS AGAINST

The Disasters a Smart Valve Prevents

Water damage doesn’t wait for you to notice. These are the real scenarios homeowners face — and exactly what a smart valve is designed to stop.

Burst Pipes

A burst pipe can release hundreds of gallons per hour into your home. A smart valve detects the sudden spike in flow and shuts down the supply within seconds — turning what could be tens of thousands of dollars in damage into a minor inconvenience.

Washing Machine Supply Line Failure

Rubber and braided supply lines to washing machines are one of the most common causes of home flooding. They fail without warning — often while you’re away. A smart valve catches the continuous flow and shuts it down before the water reaches your floors and walls.

Slow Hidden Leaks

A toilet that runs intermittently or a pinhole leak behind a wall can waste thousands of gallons and cause mold before you notice. Smart valves with daily health tests (like Moen Flo) detect these micro-leaks that would otherwise go unnoticed for weeks or months.

Vacation Disasters

The worst water damage often happens when homeowners are away for extended periods. A smart valve gives you full remote control and automatic protection — so you can enjoy your trip without worrying about what’s happening at home.

Water Heater Failure

When a water heater tank fails, it can dump 40 to 50 gallons of water into your home — and the supply line keeps feeding it more. A smart valve recognizes the abnormal flow pattern and stops it, limiting the damage to a manageable cleanup.

Fixture & Appliance Connections

Dishwasher supply lines, ice maker connections, toilet fill valves — any pressurized connection in your home can fail. A smart valve monitors the entire system from a single point, catching any failure anywhere in your home’s plumbing.

Smart Valve FAQ

A smart water shutoff valve installs on your main water line and uses sensors to monitor flow, pressure, and usage patterns around the clock. It learns your household’s normal water behavior over the first few weeks. When it detects an anomaly — like continuous flow that suggests a burst pipe, a running toilet, or a supply line failure — it automatically shuts off the water supply and sends an alert to your phone.

Many homeowner’s insurance companies offer discounts for homes with smart water shutoff valves because they significantly reduce the risk of water damage claims — which are the most common and expensive type of claim. The discount varies by provider, but it can help offset the cost of installation. We recommend checking with your insurance company to find out what discounts may be available.

Yes. Both Leak Defense and Moen Flo have battery backup systems that keep the valve operational during power outages. The valve will remain functional and can still shut off automatically if a leak is detected while the power is out. You won’t lose protection during a storm or outage.

When properly sized and installed by a licensed plumber, a smart water shutoff valve does not noticeably reduce water pressure. The valve uses a full-port design that allows unrestricted flow when open. Our master plumbers ensure the valve is correctly matched to your home’s pipe size during installation.
