A whole-home leak detection system is a smart monitoring device with a motorized shutoff valve, installed on the main water supply where it enters the house. It tracks flow, and on many models pressure, to tell normal use from abnormal flow such as a burst pipe, a running fixture or a slow hidden leak. When it sees a problem it can alert you through an app and close the valve automatically. Devices such as Flo by Moen and Phyn work this way.
A whole-home leak detection system is an insurance policy you install on the pipe. The device goes on the main supply line where water enters the house, usually after the main shutoff and pressure regulator, and monitors every gallon that passes. It learns what normal looks like for your household and flags flow that does not fit: a burst line pouring water, a toilet running for hours, or a small continuous draw that can point to a hidden leak. Depending on the model and settings, it alerts your phone and closes its valve automatically.
The benefit is greatest where a failure could run unnoticed. Homes that sit empty for weeks, owners who travel, rentals and second homes, and houses with aging copper, polybutylene or a past slab leak all gain the most. In a home where someone is around most of the day, the case is weaker, and we will say so. A system is not a repair and does not replace maintenance - it limits damage when something fails. It can also prompt a check when it reports continuous flow, which is when Electronic Leak Detection or Slab Leak Detection & Repair takes over.
We confirm the main line size and location, install the device with the right fittings, connect power and Wi-Fi, and set thresholds so long irrigation or pool fills do not cause nuisance shutoffs. You get a written price before work starts. Call (702) 438-3357 to plan an installation.

Supply lines to toilets, sinks and washing machines failing while the home is empty. Burst pipes in walls or garages that run for hours before anyone notices. Slow hidden leaks under the slab that only show up as continuous flow on the meter. Running toilets and dripping fixtures wasting water unnoticed. Nuisance shutoffs from systems installed without proper configuration.
Call (702) 438-3357. We check your main line size and location, power and Wi-Fi access, and whether a system suits your home, then give a written price.
We install the monitoring device and shutoff valve on the main supply with fittings matched to your pipe, keeping the valve accessible.
We set up the app, adjust thresholds for irrigation, pool fills and normal use, and run a test shutoff to confirm alerts work.
We show you how to read alerts, reopen the valve, and what to do if the system reports continuous flow.
A whole-home leak detection system in the Las Vegas Valley typically runs $300 to $800. That is a typical valley range, not a quote. The price depends on the device chosen, the size and location of your main line, and what is needed for power and Wi-Fi at the install point. We can give a general idea on the phone, and you get a written price on site before work starts. Most installations, including app setup and a test shutoff, are completed in one visit.
The device is installed on the main water line where it enters the house, typically downstream of the main shutoff and pressure regulator, using fittings matched to the existing pipe. We check the line size against the device, confirm a power source and Wi-Fi signal at the location, and mount it so the valve stays accessible. After installation we set up the app, adjust flow and time thresholds for the household, and run a test shutoff to confirm alerts and the valve work.

Think about how often the home sits empty, whether you have had a leak before, and where your main water line enters the house. Check whether there is an outlet and Wi-Fi signal nearby. Then call Active Plumbing at (702) 438-3357 to talk through whether a whole-home leak detection system makes sense for you.
Active Plumbing installs whole-home leak detection systems on the main water line of homes across Las Vegas and the rest of the valley. The device, such as Flo by Moen or Phyn, goes where the supply enters the house, usually downstream of the main shutoff and pressure regulator, and watches every gallon that passes. When flow looks like a burst line, a running toilet or a slow hidden draw, it alerts your phone and can close its valve automatically.
The visit starts with the main line itself. The technician confirms the pipe size and location, checks for a power source and a Wi-Fi signal at the install point, and mounts the device with fittings matched to the existing pipe so the valve stays accessible. After installation comes app setup, threshold settings for your household and a test shutoff to prove the alerts and valve work. Most installations are completed in one visit.

Local construction is the first difference. Most valley homes sit on concrete slabs with supply lines running underneath, so a leak can feed water under the floor for weeks before warm tile or a damp baseboard gives it away. A monitoring device on the main line sees that small continuous flow long before the floor does, and when it reports one, Electronic Leak Detection or Slab Leak Detection & Repair can find the source. Homes with aging copper, polybutylene from the 1970s to early 1990s, or a past slab leak gain the most.
Water use patterns matter too. Many valley homes run long irrigation cycles or top up pools, and a system left on factory settings can mistake those for a leak and shut the water off. Active Plumbing sets the flow and time thresholds around how your household actually uses water. Very hard water, about 280 parts per million or roughly 16 grains per gallon, also leaves scale on valves over time, which is one reason to keep the device where it can be reached and checked.
Finally, the valley has many second homes, rentals and owners who travel through the summer, and an empty house is where an automatic shutoff earns its keep. If someone is home most of the day, the case is weaker, and you will hear that honestly. Call (702) 438-3357.
Real reviews from customers we've served for Whole-Home Leak Detection System.
The water hammer from the washer was shaking the hall pictures. Arrestors at the box and a re-secured drop from the attic. We were in The Section Seven, Las Vegas. The house went quiet on spin cycle.

The kitchen pot-filler dripped behind the range and warped the toe-kick. Shutoff, new valve, and a listed drop from the cold riser. That call was from Rhodes Ranch. The range slid back and the wood is drying.

The water bill jumped 40 percent and the slab felt warm by the hallway. Electronic listening pinned the leak under the tile before anyone jackhammered. That call was from Southern Highlands. They opened one small square, sleeved the line, and the meter calmed down.

A whole-home leak detection system in the Las Vegas Valley typically runs $300 to $800. That is a typical valley range, not a quote. It depends on the device, your main line and what is needed for power and Wi-Fi. Active Plumbing gives you a written price before any work begins.
It monitors water flowing through your main line and compares it with your normal use. When it sees something that looks like a leak, such as a burst line or water running for hours, it alerts your phone and can close its valve to shut off the house. It limits damage from a failure rather than preventing the failure itself.
Homes that sit empty for periods, owners who travel often, second homes and rentals, and houses with aging pipe or a history of leaks. If someone is home most of the day and the plumbing is sound, a leak is usually noticed early anyway, and we will tell you if the case is weak for your house.
It can flag small continuous flow that should not be there, which is often an early sign of a leak under the slab. It does not tell you where the leak is. Finding it still takes Electronic Leak Detection or Slab Leak Detection & Repair, but knowing early can keep the repair smaller.
Most devices need power at the installation point and use Wi-Fi to send alerts to your phone. Without a reliable connection you may not get alerts when you are away, so we check signal and power at the main line before choosing where and what to install.
It can if it is left on default settings. Long legitimate uses such as irrigation cycles, filling a pool or a long shower can look like a leak. We set flow and time thresholds for your household during installation, and you can adjust them or reopen the valve from the app.
It depends on the building department for your address, such as the City of Las Vegas, Henderson, North Las Vegas, Boulder City or Clark County for unincorporated areas. The work is done to the local plumbing code, and if a permit is required we handle it.
