Got a Letter From Your Insurance Company?
Letters use phrases like "water leak detection device," "automatic water shutoff," or "smart shut-off valve." In most cases, they want a device on your main water line that watches water use and shuts off the supply when it sees a major leak.
We install Flo by Moen and many other automatic shut-off devices. To get it right the first time, have this ready when you call or book:
- The insurance letter or email, and your carrier's name
- The exact device or features they require
- Any deadline on your renewal notice
- Whether you're on city water or a private well

What It Protects Against, and What It Doesn't
A smart shut-off valve is great protection, but it isn't magic. Here's the honest version.
Leaks after the device
- Burst pipes and failed supply lines
- Running toilets and abnormal fixture use
- Washer, dishwasher, and fridge line leaks
- Water heater leaks
- Leaks while you're away from home
Not covered
- Roof leaks and rain intrusion
- Groundwater, flooding, and stormwater
- Sewer backups and sump overflow
- Leaks on the supply side, before the device
- A device that's bypassed or not set up

What We Check Before Installing
Insurance letters make it sound simple. The plumbing details decide whether the device actually protects your home.
Pipe size & material
So the device and fittings match your plumbing.
Location & access
The best spot on the main line, with room to service it later.
Power & Wi-Fi
Most smart devices need both for alerts and remote control.
Pressure & extras
Regulators, filters, and older piping can change the plan.
Already bought a device? We can install many customer-supplied shut-off valves when they fit your plumbing and your insurance requirement.
On a Well? We Do Those Too.
Plenty of Northern California homes run on private wells, with pressure tanks, booster pumps, and filters. Shut-off valves usually work fine on them, but the layout needs a closer look.
- Sediment protection. Moen's Flo specs call for a fine-mesh wye strainer when the device sits ahead of filtration on well water. We plan for it.
- Pressure tank layout. The device goes where it protects your home's actual water path.
- Power & Wi-Fi reach. Trickier near pump houses and outdoor equipment.
- Fire suppression systems. Reviewed so the device never interferes with them.

- Moen's insurance verification letter, available in the Flo app once the device is online
- App setup help to get the device connected

A Burst Line Doesn't Wait Until You're Home
Most of the water damage we see didn't start as a disaster. It was a supply line under a sink or a fitting behind the washer that let go while the family was at work or away for the weekend. By the time anyone walked in, the floors were soaked.
That's exactly what these devices are for, and it's why so many insurance companies are asking for them now. When we install one, we put it where it actually protects your home, help you get it connected, and hand you the paperwork your insurance company wants. One price before we start.

Automatic Shut-Off Valve Questions, Answered
Insurance letters, Flo by Moen, wells, and what it costs. Straight answers here.
Why is my homeowners insurance asking for an automatic water shut-off valve?
Insurance carriers are trying to reduce large water damage claims from burst pipes, failed supply lines, appliance leaks, and leaks that happen while no one is home. Requirements vary by carrier, home, location, and policy. If your insurance company sent a letter, confirm the exact device features and documentation they require before installation.
What is an automatic water shut-off valve?
It is a whole-home leak detection device installed on the main water line. It monitors water flow and pressure, alerts you through an app when it sees unusual use, and can automatically shut off the water when it detects certain leak conditions. That is different from a basic leak sensor, which only alerts when water reaches it.
Does Flo by Moen meet homeowners insurance requirements?
Flo by Moen is one of the most commonly requested devices, but each carrier decides which devices and documentation satisfy its policy. Earl's Plumbing installs Flo by Moen, helps with app setup, and provides proof of purchase and installation on company letterhead with CSLB #772565. Moen also offers an insurance verification letter through the Flo app.
Can you install a shut-off device I already bought?
Yes. Earl's Plumbing can install many customer-supplied automatic shut-off devices when they fit the home's plumbing and the insurance requirement. Before installing, we verify pipe size, device size, fittings, location, power, Wi-Fi, pressure, and existing valves so the device protects the home the way it should.
Will a smart water shut-off valve lower my insurance premium?
It may. Some carriers offer discounts for water flow detection and shut-off devices, and some require them for certain homes, but eligibility and discounts vary by insurance company, policy, and device. Ask your agent before installation so you know which device and documentation they want.
Can automatic shut-off valves be installed on homes with wells?
Usually, yes, but the layout needs a closer look. Well systems may have a pressure tank, booster pump, filtration, or sediment. Moen's Flo specifications call for a fine-mesh wye strainer when the device must go ahead of filtration on well water, so we review filtration, power, Wi-Fi, and placement before recommending an install.
Will an automatic shut-off valve stop every kind of water damage?
No. A whole-home shut-off device helps with leaks and unusual flow after the device, like burst pipes, running fixtures, and failed appliance or water heater lines. It does not protect against roof leaks, groundwater, exterior flooding, sewer backups, or leaks on the supply side before the device.
How much does automatic shut-off valve installation cost?
It depends on the device, pipe size and material, where the main line is, and whether power, filtration, or plumbing changes are needed. We look at your setup, explain your options, and give you one upfront price before we start. There's no service call fee, and online customers get $25 off.
