Water Leak Detection & Automatic Shutoff Systems in Charleston & the Lowcountry

Moen Flo and FloLogic water leak detection systems with automatic shutoff, installed by licensed ALL Plumbing plumbers, that turn off your water when a leak starts.

A burst supply line, a failed water heater or a slow leak behind a wall can do thousands of dollars in damage before anyone notices, especially in a second home, a rental or a house left empty during a trip. A smart water shutoff valve goes on your main water line, watches how water flows through the house, and closes the valve on its own when it detects a leak. ALL Plumbing installs FloLogic and Moen Flo systems for homeowners across Charleston, Mount Pleasant, Daniel Island, Kiawah, Summerville, Moncks Corner, Bluffton, Hilton Head Island and the Lowcountry.

How a Smart Water Shutoff Works

The valve is installed on the main water supply where it enters the home, after the main shutoff and pressure-reducing valve. It monitors water flow and pressure, learns your household’s normal use, and automatically shuts off the water when it sees a leak pattern, such as water running far longer than normal. You get an alert, and you can open or close the valve from your phone or at the valve.

FloLogic vs. Moen Flo

FloLogic

FloLogic is a flow-based leak detection and automatic shutoff system made for whole-home and whole-property protection. It is a strong fit for larger homes, second homes and vacation properties, and for owners who want protection that keeps working even if the internet goes down. Optional connectivity adds remote alerts and control.

Moen Flo

Moen Flo is a Wi-Fi smart valve with an easy phone app. It tracks daily water use, runs automatic health tests to catch small hidden leaks, and lets you shut off water from anywhere. It is a good fit for primary homes and owners who want detailed water-use data. It needs Wi-Fi and a nearby power outlet.

Not sure which is right? We’ll look at your main line size, where the valve can go, Wi-Fi and power, and how the home is used, and recommend the best option.

Who Should Install a Smart Water Shutoff

• Second homes and vacation homes: Kiawah, Seabrook, Isle of Palms, Hilton Head and Bluffton homes that sit empty for weeks.
• Rental and short-term rental properties: catch leaks between guests.
• Homes with older plumbing: polybutylene, galvanized or aging supply lines and older water heaters.
• Homeowners who travel: shut off water from your phone while you’re away.
• Homes with finished spaces: slab homes, finished bonus rooms and second-floor laundry rooms where a leak spreads fast.
• After a leak or water heater replacement: add protection while the plumber is already there.

Smart Water Shutoff FAQs

How much does a smart water shutoff cost to install?

Cost depends on the system, valve size and where it goes on your main line. We give you an upfront, installed price after a quick look at your plumbing.

Will it shut off my water when I’m running the irrigation or filling a pool?

These systems can be set for normal high-use activities, and you can pause protection or adjust settings. We help set it up around how your household uses water.

Does it need Wi-Fi?

Moen Flo needs Wi-Fi and power for its smart features. FloLogic can protect the home without an internet connection, with optional connectivity for remote alerts.

Can it be added to an older home?

Yes. In many older homes it is one of the best upgrades, and we can check the condition of the main line and pressure-reducing valve at the same visit.

Do you install leak sensors too?

Yes. Point sensors near water heaters, washers and under sinks add another layer of protection alongside the main shutoff valve. Also see our leak repair services.
