Moen Flo: Our Master Plumbers Review

You’re interested in installing a smart water shutoff in your home. Maybe you read about the insurance discounts you can get- or a big leak ruined your favorite couch while you were on vacation with the family.

Our team reviewed the Moen Flo Smart Water Monitor & Shutoff alongside other leading smart shutoff brands. Overall, we recommend the Flo for specific buyers who want an easy learning phase and simple, user-friendly app experience. Its large leak detection is strong, but lack of location specifics and a plastic turbine are causes for concern.

We spent 16 hours researching the Moen Flo. We joined the Moen Flo dealer network for further product insights, and we interviewed Jason M. Pond of Swingle Collins & Associates for an expert insurance perspective. 

We’ll discuss the core features the Moen Flo provides. We’ll cover the pros and cons that matter to real users in their everyday lives, as well as the cost to own and maintain the system.

Why You Should Read This Moen Flo Review

At Mother, our licensed plumbers see more smart water shutoff products than most homeowners ever do. We install them weekly, repair them when needed, and replace the ones that don’t hold up over time. 

Our regular use and working knowledge of automatic smart water monitoring systems gives us a clear view of which products and features work- and which ones don’t.

Then, we tell you what we learned in simple terms anyone can understand.

Why trust Mother’s product reviews?

We’re a plumbing service. We write reviews to earn business, not just to be nice.

It’s in our best interest to write great reviews and recommend the best plumbing products possible. It keeps our customers happy, their homes efficient, and saves everyone time.

Moen Flo Smart Water Monitor & Shutoff: The Bottom Line

If you’re a first-time smart shutoff buyer who wants a very simple app and alert calls instead of texts, then the Moen Flo Smart Water Monitor & Shutoff is a solid contender for your home smart water assistant.

Flo is the easiest to learn smart shutoff at its price point, and appeals to buyers who value a simple app experience and learning phase (the first week, where your Flo learns how your household normally uses water). 

Tech-driven power users may prefer the more detailed reporting and small leak detection of the Phyn Plus 2nd Gen model.

Here’s a quick overview of things that mattered to homeowners in our review process:

Setup: Hire a licensed plumber with working knowledge of Moen Flo products to handle critical install steps on your water line, especially the soldering portion

Learning phase: Flo’s learning phase takes roughly one week- this is several weeks shorter than competing brands like Phyn Plus. You won’t get the same deep insights as Phyn- but if you’re looking for speed over complexity, it’s a much faster learning process.

Performance: Flo is proficient at detecting catastrophic water leaks and major unusual water usage in your home. It claims the ability to detect leaks as small as one drop per minute. Flo uses a plastic turbine- this internal moving part is prone to damage from hard water and sediment.

App: The Moen Smart Water app is the easiest smart water monitoring app to use, period. You won’t get the depth of reporting that Phyn offers- but Phyn’s app is far more complex to learn for most people. App resets are also pretty simple.

Price: The list price for Moen Flo is most comparable to the Phyn Plus 2nd Generation, making them natural competitors in the space. There is no mandatory subscription to use Flo- but certain features (live support and enhanced data) are paywalled for $5/month in the FloProtect plan.

Warranty: Flo offers a 1-year limited warranty, with the option to extend to five years for $5/month through the FloProtect plan.

Recommendation: Flo is a more than competent product for homeowners concerned about leak damage who don’t want to learn a complex app or bother with detailed reporting. Be sure your insurance carrier offers incentives for installation- Flo isn’t as popular with insurers as Phyn Plus.

Stats and Analysis: Moen Flo Smart Water Monitor & Shutoff

Let’s start with the basics. How does Flo by Moen work? Does installing Moen Flo products lower your insurance premium? And what are real industry experts (our Master Plumbers and others) saying about it?

Moen Flo: product features

Insurance discounts and rebates available

These 7 major insurance providers currently offer discounts and rebates for homeowners who install Moen Flo Smart Water Monitor & Shutoff devices:

• Travelers
• Chubb
• Liberty Mutual
• Nationwide
• Farmers Insurance
• American Family Insurance
• Amica

We asked Jason M. Pond of Swingle Collins for his expertise for two reasons. He’s a “Best in Dallas” personal risk advisor for 14 consecutive years. As a risk assessment expert- and someone who’s lived through his own water damage claim- he knows first-hand what carriers are looking for in a smart water system.

“As part of a water claim, if the company will pay for a portion of the parts and installation/labor,” Jason states. “Check with your home insurance company and see if installing a leak defense system will offer you a policy credit.”

Flo checks an important box for insurers- a whole-home monitoring system.

“Typically, insurers favor whole-house, flow-based automatic water shut-off devices that are installed at the main water supply line entering the property,” Jason continues. “These systems often include advanced technology that detects unusual water flow or pressure changes, triggering alarms and sending real-time alerts via text or email.”

Moen Flo currently has good insurance discount and installation rebate options with 7 major providers. It does lag behind Phyn Plus (15 companies).

Flo by Moen water rebates

Some municipalities and water companies offer rebates for homeowners who install Moen Flo products. The most notable examples are in California through the California Water Efficiency Partnership (CalWEP).

Moen Flo buyers should search for “flow monitor rebates” and “smart water monitor rebates” through their local water providers.

Expert recognition and studies

A LexisNexis Risk Solutions study found homes with Moen Flo reduced the frequency of paid water damage claims by 96% vs. homes with no flow monitoring device.

In 2021, Consumer Reports ranked Moen Flo the best professionally installed water leak detector system, noting its wireless leak sensors and built-in flow sensor.

Our Master Plumber talks about Moen Flo

We spoke to our Responsible Master Plumber, Steven Smith, about his hands-on experience with the Flo Smart Water Monitor and Shutoff. Steven is the head of our Mother Modern Plumbing team, which is a part of the Moen Flo dealer network.

Steven says a majority of consumer happiness with Flo is due to good customer experience through the app and robocall leak alerts.

“They spent a lot of time engineering the app,” Steven explains.

Installation of the Moen Flo is straightforward for licensed plumbers, especially those with Flo-specific training from the manufacturer. Steven cites his experience with the Moen Flo dealer network as a benefit.

Ultimately, Steven does prefer Phyn Plus as a comprehensive flow monitoring system for homeowners concerned about water damage and leaks. He cites some insurance industry concerns about Flo’s ability to detect smaller leaks that cause gradual damage over time.

“There are some known issues with the Moen Flo in terms of not registering a small water leak,” Steven says. “They may or may not have corrected those issues- but because of them, some insurance companies accept it less as a whole home water shutoff.”

What It’s Like to Live With Moen Flo Products

It’s just as important to find out what customers who own smart shutoff think about their purchase. Most homeowners who call us about the Moen Flo do so during the learning phase, with questions about early false alarms. We get very few questions about the app.

We also read 68 customer reviews of the product that we judged to be real (no bots, paid reviews or fake reviews).

Here’s what people are saying about the Moen Flo Smart Water Monitor & Shutoff.

Real-world pros and cons of ownership

Our team sought out feedback from Moen Flo owners that offered brand-specific insights. This allows you to see the unique benefits of Flo compared to other smart shutoff devices.

Pros of the Moen Flo Smart Water Monitor & Shutoff:

• No third-party valve. Some smart water monitors require you to buy a separate valve to physically turn the water off. Flo offers monitoring, detection and the valve.
• Simple learning phase. Flo takes one week to learn your household water habits (vs. 1,000 hours for the Phyn Plus). Depth of reporting isn’t as great, but you do get the same detection of catastrophic leak events.
• Easy-to-use app. Scared of smart tech and complex apps? The Moen Smart Water app was the easiest to learn for our new shutoff customers.
• Robocall leak alerts. Customers like the automatic call feature- Flo sends a robocall when it detects a leak, rather than an “easier to ignore” push notification.
• Good smart alarm compatibility. Flo pairs with Alarm.com and Nice security monitoring systems- great if you want your alarm company to react to potential leak events.
• What you need is in the box. Connection fittings, O-rings, installation spacer, power adapter- it’s all there when you open your Moen Flo.
• Optional extended coverage. For $5/month, the FloProtect plan extends your warranty to five years and offers $5,000 coverage toward your home’s insurance deductible in case of water damage. (This plan also has negative “paywall” aspects.)
• Good customer support. The customer service line is open 55 hours a week, Monday-Friday. That’s 10 more hours a week than Phyn customer service. Owners state the Moen reps are friendly and patient. 

Cons of the Moen Flo Smart Water Monitor & Shutoff:

• Plastic turbine = more repairs. Flo operates with an internal plastic turbine (vs. Phyn’s ultrasonic flow sensors). This internal moving part is more likely to cause repairs.
• Misses some small leaks. Flo’s going to catch catastrophic leak events- but it may miss that slow, persistent drip behind your toilet.
• Less overall insurance adoption. Insurance agencies lean towards installation discounts and benefits for Phyn Plus (15 agencies) over Flo (7)*. Make sure your insurer offers incentives for Moen Flo before installing.
• One-year limited warranty. Other competing products offer a stronger warranty- in particular, Phyn Plus 2nd Generation devices have a 2-year warranty.
• Reporting isn’t highly specific. You’ll get an alert for unusual water usage, but there’s no specific information as to which supply line or fixture is the issue.
• Small paywall. Live support and enhanced water usage data are part of the FloProtect plan, which costs an extra $5/month.

What real homeowners say about Flo by Moen

Here are three helpful reviews from homeowners who installed the Flo Smart Water Monitor and Shutoff on their water line. Their insights range from installation to learning phase, fixture specificity to app usage:

⭐⭐⭐⭐⭐”Bought this and had it installed . Works perfectly after it went through the learning process. My sprinklers came on before it was properly programmed and shut my main off which is good, shows me that it’s working. After the 7 days of learning it is working perfectly. Highly recommended.” – Owner via Home Depot

⭐⭐⭐⭐ “Pros: It is nice to turn the water valve off remotely, especially for me, since the water valve is in a crawlspace… Cons: Very expensive. It doesn't seem to adequately detect what fixture is being used. It just says "toilet" or "faucet" for 99% of usage….Overall I'm happy with it for the remote control alone.” – Owner via Home Depot

⭐⭐⭐ “This is a good app with one fatal flaw: it only allows one phone number and email address for notifications. A family member, neighbor, etc. will not receive email or text alerts…it would be nice for them to get alerts without needing the app.” – Raul B. via Google Play

We reviewed internal service data from customer calls alongside vetted online reviews. These are the 3 most common critiques about Moen Flo:

1. Are sensors a must? Many users, especially on Reddit, state that purchasing several add-on water sensors is necessary for optimal performance.
2. Some missing specifics. Owners like the reporting, but want more concrete information. You’ll find out there’s a leak, but not the specific sink, appliance or supply line where it’s happening.
3. FloProtect gets mixed reviews. The ability to extend your warranty is great, but some homeowners dislike live customer support and extra water data living behind a paywall.

Purchase and Installation Costs

In this section, we’ll cover the true overall cost of Flo by Moen devices- not just the purchase price, but the cost to install the product. 

How much does Flo by Moen cost?

As of this publication, Moen’s website lists the Flo Smart Water Monitor and Shutoff at $649.99. We found the product at Home Depot for between $520-$550.

Moen offers the Smart Water Shutoff as a solo product for $449.99. A 3-pack of smart leak detectors and 25’ extension cable are also sold separately.

How much does it cost to install Flo by Moen?

This data varies from region to region, but it generally costs between $3,100-$5,100 to get the Flo Smart Water Monitor and Shutoff installed. In these instances, the cost of purchase is included in the total installation.

Here are the four core drivers of Flo by Moen  installation costs:

1. Do you need to trench or excavate to move your existing water line?
2. Do you need to run new electrical for the device?
3. Do you already have a shut-off valve inside your home?
4. Does your water line need to be rerouted to accommodate the device?

Why you need a licensed plumber to install Flo by Moen

Most insurance companies want your rebate or discount submission to include proof of installation by a licensed plumber- the bill, your plumber’s name and license number. This goes double for Flo, as it’s installed on the main water line and involves soldering.

Improper installation that causes product damage, defects or even slight modifications voids the entire limited warranty.

Moen Flo’s Smart Water Shutoff Manual recommends that only “authorized service providers” provide maintenance and repair under warranty terms.

Flo by Moen: Our Plumbers’ Conclusions

The ideal customer for the Flo Smart Water Monitor and Shutoff is a homeowner who values simple user experience and respects the Moen brand. The tradeoff: some paywalled enhanced features, slightly less-detailed reporting and less overall adoption by insurance providers.

The plastic turbine inside Flo causes some repair and replacement issues, as does the battery pack. If you need to call customer service, they’re open longer and viewed as more pleasant on the phone.

While Flo doesn’t top our list of best smart water monitors for most homeowners, it certainly provides the security and peace of mind of a quality smart shutoff product. Overall, our Master Plumbers rate it 2nd best at its price point, behind the Phyn Plus.
