Smart Water Shutoff Systems

The water damage that never happens.

A burst supply line does not wait for someone to be home. It lets go at full street pressure, on its own schedule, and the bill is decided by how long it runs before anyone notices. A smart water shutoff ends that gamble. We install and configure Moen Flo and Phyn monitors on the main line: professionally mounted, paired to your phone, and proven with a live shutoff test before we leave. From then on, your plumbing watches itself.

Why Smart Shutoff

A flood is just a leak nobody caught in time.

Here is the version of this story we never want told about your house. A supply line or a corroded fitting lets go on a Friday afternoon, the family is at the coast until Sunday, and clean water runs at full pressure into the laundry room for two days. Nobody was careless. The house simply had no way to say anything, and what should have been a mop-up became new floors, new drywall, and weeks of dehumidifiers.

A smart water monitor closes that gap. Mounted on the main line, it measures every drop moving into the house: how much, how fast, at what pressure. Within days it has learned your household’s rhythm, morning showers to evening dishwasher. When flow shows up that does not fit the pattern, it pushes an alert to your phone. When the flow looks like a failure, it closes the valve on its own, with nobody awake, home, or anywhere near the shutoff.

The quieter benefit is what these systems find below the threshold of human attention. Automated pressure tests catch drip-rate leaks and pinholes months before they would ever show as a stain. Most Portland homes still have nothing like this on the main, which is why we made smart water shutoff installation a featured service instead of a special order: it is the rare upgrade whose entire job is making sure you never need our bigger ones.

It learns your household

The first days are school. Showers, laundry, irrigation, the teenager’s twenty-minute rinse: the system builds a profile of normal so it can recognize wrong.

It catches micro-leaks

Automated pressure checks flag drip leaks and pinholes long before they announce themselves through a ceiling.

It closes the valve itself

Burst-scale flow triggers an automatic shutoff at the main within moments, no app open, no one home.

It keeps you in the loop

Alerts, usage dashboards, and remote shutoff live on your phone, so you can close the water from the coast or the couch.

Two Systems, Compared

Moen Flo or Phyn? Both earn the wall space.

We are not going to steer you toward the unit with the better margin, because we install both and would put either one in our own home. Moen Flo and Phyn Plus reach the same destination by different roads: one reads the water directly, the other reads the pressure waves the water makes. Here is the comparison we walk through at the kitchen table, minus the spec-sheet fog.

What matters	Moen Flo	Phyn Plus
How it watches	Measures flow, pressure, and water temperature directly and continuously on the main line.	Samples pressure waves at very high frequency and learns the distinct signature of each fixture.
How it finds slow leaks	Runs automatic health tests, usually overnight, that can surface drip-rate leaks.	Runs automated plumbing checks that watch for the telltale pressure decay of pinhole leaks.
When a burst hits	Closes its built-in shutoff valve automatically and sends the alert to your phone.	The same instinct: automatic shutoff at the main, with the details waiting in the app.
The app	Companion phone app with usage dashboards, away mode, alerts, and remote shutoff.	Phyn app, with a fixture-level picture of where the water in your house actually goes.
Growing the system	Pairs with Moen’s wireless leak detectors for point protection under sinks and beside the water heater.	Designed to deliver whole-home coverage from the single unit on the main.
Pedigree	Backed by Moen, a fixture name your house probably already carries somewhere.	Built by a team with deep piping roots, and the plumbing-first design shows.

The Panda Install

Installed on the main, proven before we leave.

Both manufacturers put these units in the same place for a reason: on the main supply line, just downstream of your shutoff valve, where every fixture in the house sits behind them. Getting one there is plumbing, not gadgetry. The unit has to match your pipe size and material, sit in the correct orientation with the straight run its sensors need, and mount solidly enough that years of vibration never loosen a fitting. A device whose whole job is preventing leaks should never be installed in a way that could cause one.

So we treat it as journeyman work. We confirm your service size on a short video call before the visit, bring the correct unit and fittings, make proper connections, and leave you a serviceable installation with isolation you can actually reach. And if the pipe feeding the house is on its last legs, the smartest sequence is one project: pair the monitor with a main water line replacement and let it start life reading brand-new pipe.

Then comes the part that separates an install from a working system. We join the unit to your Wi-Fi, create your account, pair every phone in the house, set the alert behavior with you, and finish with a live shutoff test you watch happen. You should not have to commission your own leak protection from a support article, and with us you never will.

Sized and confirmed

A quick video call verifies your pipe size, material, and shutoff location, so the truck arrives with the right unit and fittings.

Mounted to manufacturer spec

Correct orientation, the required straight run, solid support, and clean connections that protect both the readings and the warranty.

Paired and configured

Wi-Fi joined, accounts created, phones paired, and alert settings tuned to the way your household actually runs.

Proven before we pack up

We trigger a test shutoff and you watch the valve close. The job ends with you knowing it works, not hoping it does.

Worth Two Phone Calls

Your insurance carrier already likes this idea.

Water damage is one of the most common claims in American homeownership, and insurers have noticed that houses with automatic shutoff devices generate fewer of them. Many carriers now offer premium discounts for a professionally installed smart water shutoff. We will not quote you a number, because every carrier writes its own rules, and the honest answer lives one five-minute call away at your agent’s desk.

The second call worth making is to us, about timing. A smart shutoff pairs naturally with the bigger projects on this site. A new water heater is the classic moment to add one, because a failing tank is one of the most common ways a house floods itself. And if you are already investing in a whole-house repipe, a monitor on the main is the least expensive protection your brand-new plumbing will ever get.

Ask your carrier, not the internet

Discounts for automatic shutoff devices vary by insurer, policy, and state, so we refuse to invent a percentage. Call your agent, ask what a professionally installed Moen Flo or Phyn does for your premium, and we will provide the installation records your carrier wants to see.

One visit, two upgrades

Adding a smart water shutoff during a water heater replacement, a repipe, or a main line project takes far less time than a stand-alone appointment. Tell us you want it on the same quote and we will price the combination exactly, in writing.

Good Questions

Smart shutoff questions, answered plainly.

Does a smart shutoff still work if my Wi-Fi goes down?

The protection lives on the device, not in the cloud. Both Moen Flo and Phyn keep monitoring flow and pressure locally, and both can still close the valve on their own if they detect a burst while your internet is out. What you lose without Wi-Fi is the remote layer: phone alerts, the app dashboard, and the ability to shut the water off from somewhere else. Once the connection returns, the device syncs itself back up.

Will it false-alarm every time I water the lawn or fill a bathtub?

Not once it knows you. Both systems spend their first stretch in a learning mode, building a profile of what normal looks like in your house, and a long steady draw like irrigation or a tub fill becomes part of that profile. Early on you may get a few check-in alerts that take one tap to confirm; that is the system learning, not failing. Both apps also let you set home and away modes and tune sensitivity, and we configure those settings with you during the install.

Should I pick Moen Flo or Phyn?

We install both and would defend either choice, so the recommendation comes down to your house and your habits. Moen Flo makes sense if you want add-on wireless leak detectors in specific rooms or already live in Moen’s smart ecosystem. Phyn appeals if you want fixture-level insight into your water use from a single unit on the main. Bring the question to your free consultation and you will get a straight answer for your specific plumbing, not a coin flip.

Can renters or condo owners install one?

Sometimes, and it is worth checking before you fall in love with the idea. The unit installs on the main supply line, so a single-family home or townhome with its own shutoff is straightforward. A condo comes down to access: a unit with its own dedicated, reachable supply line can usually take one, while a main that is shared or buried in a common wall rules out a whole-unit shutoff, though point leak sensors can still help. Renters need the owner’s written approval, since this is a permanent plumbing modification. Send us a photo of your shutoff or hop on a quick video call and we will tell you where your place lands.
