FLO® by Moen Water Leak Detection System

Water damage is one of the most common and costly homeowners insurance claims, and it usually starts with a leak no one sees. A burst supply line, a failed water heater, or a slow drip behind a wall can cause thousands of dollars in damage to floors, walls, cabinets, and even your slab foundation, often while you are asleep or away from home.

The Flo by Moen Smart Water Shutoff watches your home's water use around the clock and can turn off the water automatically when it detects a problem. Nick's Plumbing & Air Conditioning provides professional Flo by Moen installation in Houston, so your system is installed correctly on your main water line and set up to protect your home from day one.

Why Leak Protection Matters in Houston Homes

• Slab foundations - Many Houston homes have water lines under or near the slab, where leaks can run for months unnoticed
• Attic and upstairs water heaters - A failed tank or fitting above your ceilings can cause major damage quickly
• Freezes and storms - The February 2021 winter storm showed how fast frozen pipes can burst across the city
• Travel and second homes - A leak that starts while you are away can run for days before anyone notices
• Aging plumbing - Older galvanized and copper lines are more likely to develop pinhole leaks

How the Flo by Moen System Works

Smart Water Shutoff Valve

The Flo Smart Water Shutoff is a motorized valve installed on your main water line where it enters your home. It continuously monitors water flow, pressure, and temperature and sends that data over Wi-Fi to the Moen Smart Water app on your phone.

Learns Your Water Use

Flo learns your household's normal water use patterns, such as morning showers and evening laundry. When it sees unusual flow, like water running for an abnormally long time, it alerts you and can shut off the water automatically.

Daily Health Tests

Flo runs regular plumbing health tests that briefly check for pressure loss in your system. These tests can find small hidden leaks, as small as a drop per minute, long before you would see a stain or a high water bill.

Control From Anywhere

From the app, you can see your water use, receive alerts, and turn your water off or on from anywhere. Home, Away, and Sleep modes let you adjust how sensitive the system is based on your schedule.

Add Smart Water Detectors for Extra Protection

Some leaks do not come from pressurized pipes, such as an overflowing toilet, a leaking water heater tank, or an AC condensate drain that backs up. Battery-powered Flo Smart Water Detectors can be placed under sinks, behind toilets and washing machines, near water heaters, and anywhere else a leak is likely. They alert you to water on the floor, as well as unusual temperature and humidity.

Our Flo by Moen Installation Process

1. Evaluate - We locate your main water line, confirm the pipe size, and check for a nearby power outlet and a reliable Wi-Fi signal
2. Install the valve - We cut in the Flo Smart Water Shutoff on the main line, typically in the garage or where the line enters the home
3. Test - We restore water, check every connection for leaks, and confirm the valve opens and closes properly
4. Set up the app - We help connect the system to Wi-Fi and the Moen app and pair any smart water detectors
5. Walk you through it - We show you how alerts, modes, and remote shutoff work so you are comfortable using the system

Is Flo by Moen Right for Your Home?

Flo is a smart investment for homeowners who travel often, own a second home or rental property, have an upstairs laundry or attic water heater, or live in an older home with aging pipes. If you already suspect a leak, our water leak repair and hydrostatic leak detection services can find and fix it first. For homes with failing galvanized pipes, our repipe specialists can replace the water lines before adding Flo.

Flo pairs well with other protection. Learn how to thaw frozen pipes safely, keep your water heater in good shape, and consider our VIP maintenance plan for annual plumbing inspections.
