If your insurance company recently sent you a letter requiring a smart leak detection system, you’re not alone. We’ve been getting a growing number of calls from Santa Cruz homeowners in exactly this situation — and it’s a trend that’s picking up across the country.

Whether your insurer is pushing you to act or you just want more peace of mind while you’re at work or traveling, this post covers what these systems do, what installation actually involves, and why we rely on the Flo by Moen system when it’s our call to make.

Our expert plumbers at Rosenthal Plumbing are ready to help with all your Santa Cruz leak detection services!

Why Insurance Companies Are Requiring Leak Detection

Water damage is one of the most common and costly claims in home insurance. Roughly 1 in 4 claims are water-related, and insurers are responding by requiring homeowners to take preventative action.

A smart leak detection system gives your home a layer of protection that traditional plumbing simply doesn’t offer. It monitors continuously, catches problems early, and in many cases can stop damage before it starts — automatically. That’s a meaningful risk reduction for insurers, which is why more of them are making it a policy requirement.

If your insurance company has sent you this requirement, they may even provide the sensor unit themselves. In that case, they just need a licensed plumber to handle the installation. That’s where we come in. If they leave the product choice up to you, we have a recommendation.

Why We Use Flo by Moen

When we get to choose the product, we install the Flo by Moen Smart Water Monitor and Shutoff system. It’s well-built, reliable, and gives homeowners genuine visibility into what’s happening with their water — not just a basic alert when something goes wrong.

Here’s what the system does:

24/7 Monitoring The system continuously monitors for moisture, extreme temperatures, and high humidity. If it detects something off, it notifies you through the Moen Smart Water App, text message, phone call, or email — whichever you prefer.

Automatic Shutoff with FloSense Technology This is the standout feature. FloSense learns your home’s normal water usage patterns over time. If something unusual happens — a flow running at 3am, a pressure drop that doesn’t match normal usage — it can automatically shut off your main water line before damage occurs. If you travel frequently or have a vacation property, this alone makes the system worth it.

Whole-Home Sensor Coverage Additional sensors can be placed throughout your home — under sinks, near the water heater, behind the refrigerator, in the laundry room. Each sensor includes an extension cable with a remote sensing disc that reaches up to 48 inches, so they work even in tight or awkward spaces. Multiple sensors connect to a single system for complete coverage.

App Control and Smart Home Integration The app (iOS and Android) shows your full water usage picture — indoor and outdoor — and lets you customize alerts for water detection, humidity, and temperature. The system also integrates with Amazon Alexa for hands-free monitoring.

What Installation Actually Involves

This is worth clarifying, because “installing a leak detector” can mean very different things depending on your home and what your insurance requires.

In some cases it’s straightforward — sensor placement and connecting the system to your app. In other cases, the scope is more involved:

• Main line shutoff integration — the automatic shutoff feature requires physical connection to your main water supply line, which is real plumbing work
• Valve updates — if your existing shutoff valve is outdated or incompatible, it may need to be replaced as part of the job
• Sensor placement throughout the home — getting coverage in all the right spots takes a bit of planning, especially in older homes with unusual layouts

Before we quote anything, we’ll take a look at your setup and understand exactly what your insurance company is asking for. Every home is different, and we’d rather give you an accurate picture upfront than surprise you later.

One thing to keep in mind: we don’t work directly with insurance companies or manage the claims process. Our job is to do the installation correctly and make sure it satisfies your insurer’s requirements.

Is This Worth Doing Even If Your Insurance Isn’t Requiring It?

Honestly, yes. The short case for it: you’re protecting your home while you’re away, and 1 in 4 insurance claims are water-related. A system that monitors your usage habits, alerts you instantly, and can shut off your water automatically is a meaningful upgrade to any home — especially in an older Santa Cruz neighborhood where pipes have some years on them.

It’s not the most glamorous home improvement. But when it catches a slow leak under a sink before it ruins your cabinets and subfloor, you’ll be glad it was there.
