What Is a Smart Water Shutoff?
A smart water shutoff installs on your home’s main water line — before the pipes branch off to your kitchen, bathrooms, and appliances. It monitors water flow 24/7 and uses flow algorithms to detect abnormal patterns like a burst pipe, running toilet, or slow leak behind a wall.
When it detects a problem, it automatically shuts off the water to your entire home and sends a smartphone alert. You can also shut off your water remotely through the app — useful when you’re traveling or notice something odd. Installation requires a 110v outlet nearby and a Wi-Fi connection in range of your main line, usually in the garage or utility room.
- The leak detection device itself — we source and supply it
- Main line installation with bypass valves for easy reset
- 110v power hookup to a nearby outlet
- Wi-Fi connection and app configuration
- Full system test and pressure verification before we leave
- Walkthrough so you know how to use the app and reset if needed
Why Install a Smart Shutoff?
Insurance Requirement
State Farm now requires leak detection devices to maintain homeowner’s coverage in many California zip codes — and other major insurers are following. This isn’t optional if you carry coverage with them. Check out our deep dive on why State Farm is requiring smart water shutoffs for more details. We install to the specifications insurers require so your documentation is clean.
- State Farm mandates these in many CA zip codes
- Other insurers are adopting the same requirement
- We document the install for your insurance file
- Non-compliance = risk of policy cancellation
Don’t risk losing your coverage
Prevent Catastrophic Damage
Water damage is the #1 cause of homeowner’s insurance claims. A slow leak behind a wall, a failed water heater, or a burst pipe while you’re away can cause tens of thousands in structural damage. A smart shutoff stops the water within seconds of detecting an anomaly — before the damage compounds.
- Detects burst pipes, slow leaks, and running toilets
- Automatic shutoff — no human action required
- Smartphone alert sent the moment something is detected
- Daily water usage data helps spot hidden leaks early
Stops damage before it compounds
Peace of Mind
Whether you’re at work, traveling, or just asleep — your water is monitored. San Francisco homes deal with aging pipes and high water pressure spikes. Marin homes face mineral-rich water that accelerates corrosion. Either way, a smart shutoff means a small problem never becomes a disaster.
- Monitor and shut off water remotely from anywhere
- Works even when you’re on vacation or traveling
- App shows real-time flow and consumption data
- 10-15 year device lifespan with minimal maintenance
Your home is protected 24/7
What to Know Before You Schedule
Straightforward install — here’s what affects your timeline and cost.
Cost Depends on Your Main Line Size
Most installations run $1,500–$2,000 all-in. The main variable is your water line diameter — larger lines require larger valve bodies, which cost more. We assess this during scheduling so there are no surprises on install day.
You Need a 110v Outlet and Wi-Fi Near Your Main Line
The device needs power and connectivity at the installation point — typically your garage or where the water line enters your home. If there’s no outlet nearby, we can help coordinate an electrician. Most homes already have both.
Water Will Be Off for a Few Hours
We briefly shut off water to your home during installation — usually a few hours total. We work efficiently and let you know the exact window when scheduling. Plan for a half-day to full-day depending on your setup.
We Check Your Whole System While We’re There
Unlike a device-only installer, we look at your pressure, inspect your main line condition, and flag anything else that warrants attention. This is included — most of the time there’s nothing to report, but occasionally we catch a slow leak or corrosion that would have been a bigger problem later.
Leak Detection by Location
San Francisco
SF’s high water pressure — often 130+ PSI — dramatically increases leak risk, especially if you have a closed-loop system with a check valve. We test your pressure and install the right device for your home’s water system.

Novato & Marin County
Marin’s hard water and aging Eichler pipe systems create unique leak risk. We understand the local conditions and common failure points in Marin homes.

Leak Detection Questions
Why does my insurance require a leak detection device?
Water damage is one of the most expensive claims insurers deal with — often exceeding $50,000 in a major event. Leak detection devices prevent catastrophic damage by shutting off water automatically. State Farm has made them a requirement in many California markets, and other insurers are following. Many insurers also offer premium discounts of 8–12% for qualifying installations. It’s cheaper for everyone when the claim never happens.
What happens if I don’t install one?
If State Farm requires it and you don’t comply, they can decline to renew your policy. Other insurers are moving in the same direction. Check your specific policy letter for the deadline — if you’ve been notified, the timeline is usually 30-90 days. We can often schedule within a week.
Will I lose water during installation?
Yes, temporarily. We shut off the main to install the valve assembly — typically a 2-4 hour window. We coordinate the timing with you when scheduling. Water is restored and tested before we leave.
What if it shuts off by mistake?
False alarms are rare, but when they do happen it’s simple to handle. We install bypass valves alongside the unit so you can restore water immediately and investigate. The app also lets you override remotely. Better a false alarm than waking up to a flooded house.
Does it require Wi-Fi?
Yes — the device connects to your home Wi-Fi to transmit alerts and allow remote control through the app. The installation point (typically the garage) needs to be within Wi-Fi range. Most modern home routers cover this without issue, but if your garage is marginal, a Wi-Fi extender is a simple fix.
Can I install it myself?
Technically yes, but insurers often require licensed plumber installation to satisfy coverage requirements. Beyond compliance, professional installation ensures correct valve sizing for your line, proper pressure verification, and a complete system test. We also check your plumbing while on-site — something a DIY install misses.
How long do these devices last?
Most smart shutoff devices last 10-15 years with minimal maintenance. The valve actuator is the component that ages — we recommend a functional test annually, which takes about 5 minutes through the app. Device replacement is significantly cheaper than the initial install since the plumbing work is already done.
Do you install these in both San Francisco and Marin County?
Yes — we serve all of San Francisco and Marin County including Novato, San Rafael, Mill Valley, Tiburon, and surrounding areas. Eichler homes in Lucas Valley and Terra Linda are a particularly good candidate — their aging in-slab radiant pipes make leak monitoring especially valuable. We also install commercial-grade leak detection systems for multifamily buildings and HOAs.
