A leak that would have soaked your floors becomes a puddle you wipe up with a towel
Most leaks start small — a supply line behind a toilet, a hose behind the washer — and run for hours before anyone’s home to notice. In your house, that story goes differently: water touches a sensor, your main line shuts itself off, and your phone gets the alert — whether you’re home, at work, or on vacation. Even the leaks you can’t see, inside a wall or under the slab, get flagged by a valve that notices water moving when nothing’s on. Installed in one visit by the Southern California contractor who rebuilds water-damaged homes every day.
100% free, no obligation. 60 minutes. You get a written Home Water Risk Report™ and a printed Emergency Water Action Plan™ whether you buy anything or not.
The Real Cost of a Small Leak
A small leak isn't the disaster. The water-damage claim is.
Most water damage starts with a leak the size of a pinhole. By the time it's found, the real cost isn't the leak — it's everything that comes after.
Your home gets torn apart
Wet drywall, flooring, cabinets, and baseboards may need to be removed before reconstruction can even begin.
Daily life gets disrupted
Kitchens and bathrooms can become unusable, drying equipment runs around the clock, and some families have to temporarily relocate.
Insurance doesn't remove every cost
Deductibles, coverage limits, depreciation, matching disputes, and approval delays can still land on the homeowner.
Repairs can take weeks or months
Mitigation, estimates, approvals, materials, and multiple trades all add time before your home is whole again.
A second loss may threaten insurability
Claim history can affect premiums, deductibles, eligibility, or renewal — depending on the carrier and policy.
Every one of these traces back to one thing: a leak nobody caught in time. The good news is that the most catastrophic failures are also the most preventable.
Why We're Different
We repair water damage every day. This is the system we install to prevent it.
You can buy a leak sensor online. You can have a plumber bolt a shutoff valve onto your main line and leave. Neither of those is what we do — and the difference is everything.
A DIY device or a plumber-installed valve
- A box you set up yourself, or a valve someone installs and walks away from.
- Sends an alert to your phone — and then you're on your own.
- No one stands behind what happens next.
- It's a product.
M. Fitts Whole Home Water Protection
- Designed, installed, and finished by a licensed installer — backed by the contractor who rebuilds water-damaged homes.
- NSF-certified automatic shutoff + whole-home leak sensors + cabinet protection, finished to a construction standard — not a gadget bolted to a pipe.
- The automatic local shutoff works even without WiFi or power.
- Optional professional monitoring through Water Protection Plus, so your protection doesn't depend only on you catching a notification.
- And the part no device company can offer: if your home ever needs water-damage repairs, you already know the contractor to call.
Simple From Start to Finish
Protecting Your Home Is Simple
Assess
We inspect the main water line, water pressure, common failure points, and the areas where sensors will provide the most protection.
Design & Install
We confirm an all-in price, install the automatic shutoff and sensors, set up the app, test the system, and finish the installation area properly.
Protect
Your system watches for leaks and can automatically close the main water supply. Monitor it yourself for free, or add Water Protection Plus.

🤝 One Call, Start to Finish
Assessment, install, and — if your home ever needs water-damage repairs — the reconstruction. The same trusted local Inland Empire team.
"We had a water leak at our home. This requires a wall of our house to be rebuilt along with a shower and much of our garage and bathroom. Matt and his team took great care to do the work properly and kept us informed with perfect communication. Things went so well we will be working with them again for some remodel work soon."
"We chose M. Fitts Construction from three bidders offered by Realm, construction management company. M. Fitts provided the best proposal and we are very pleased with the work."
"I had a very positive experience with this company. They were very professional and detailed. I love their work. They brought my vision to life!"
Comes With Every Install
Our Promise: Never Face Water Damage Alone
No system can promise that water will never escape or that damage can never occur. We can promise to install your protection correctly, stand behind our workmanship, and be the contractor you can call if your home ever needs water-damage repairs.
If damage ever occurs, you already know who to call
If water damage occurs, M. Fitts Construction can inspect the construction damage, document the repair scope, prepare a detailed construction estimate, communicate about the construction work, and rebuild the affected areas. The homeowner remains responsible for the insurance claim and coverage decisions unless they separately retain an appropriately licensed insurance professional.
Workmanship: if our installation workmanship is defective, we will make the installation right in accordance with our written workmanship warranty.
The Walkout Test
Every install ends the same way: with you watching.
Before we leave, we touch water to a leak sensor and you watch the system fire — sensor to hub to valve — until your home’s water shuts off, live, on your own phone.
No fine print. The test either passes in front of you, or the install isn’t finished.

It’s not just waiting for a leak
The FlowSmart valve is an ultrasonic water meter and a shutoff in one unit — which means it’s working every day, not just on the worst day:
We rebuild these homes. Here’s the math nobody shows you.
M. Fitts Construction has spent years rebuilding Inland Empire homes after water losses. Even for a homeowner with good insurance, here’s what a supply-line failure typically costs out of pocket:
The average non-weather water damage claim runs about $14,000 — that's the size of the claim your insurer processes, not the check you write. What you actually pay is the deductible, the plumbing repair that caused it, the full rebuild if the claim is denied, and the higher premiums that follow a paid claim — plus weeks of living in a house being dried out. Against that, whole-home protection is about $2,000 for a 4-bed, 3-bath home — one price, no subscription required. Phone alerts and app control are included free for as long as you own it.
You May Not Pay Full Price
Your insurer or water agency may offer savings
Discounts and rebates depend on the installed equipment, insurance carrier, policy, local water agency, available funding, and current program rules. We help you check potential eligibility and provide installation documentation. Your insurer and water agency make the final eligibility and payment decisions.
A possible insurance discount
Some California carriers, including Mercury, describe premium discounts for qualifying leak-detection or automatic-shutoff devices, with actual savings varying by carrier and policy. Your insurer confirms the amount; we provide the proof of installation.
A possible water-agency rebate
SoCal Water$mart currently describes rebates starting at $100 for qualifying flow-monitoring devices, with eligibility varying by agency, model, and available funding. We'll help you check whether your home qualifies.
We help with the steps
We help identify the program, provide the installation documentation, and assist with the application steps. Final eligibility and payment are decided by your insurer and water agency.
Discounts and rebates vary by carrier, policy, device model, and water agency, and rebate funding is limited. We don't guarantee eligibility for any specific rebate or discount; your insurer and water district confirm the exact amounts.
Your Free Assessment
Start with the free assessment
A licensed contractor evaluates the visible water-supply risks in your home, checks water pressure, identifies likely sensor locations, reviews the main-line installation area, and prepares a practical protection plan. There is no obligation to purchase an installation.
What the assessment includes
Book your assessment and you keep all of this — whether you hire us or not:
- A visible-risk inspection of the common failure points in your home.
- A written Home Water Risk Report™ — findings, photos, and a custom protection plan.
- A printed Emergency Water Action Plan™ — what to do the moment water happens — and we find and label your main shutoff.
- An installed-price recommendation and a check for potential insurer/water-agency savings.
- Washing-machine hoses
- Angle stops under sinks & toilets
- Toilet supply lines & fill valves
- Water heater, T&P valve & drip pan
- Dishwasher & fridge/ice-maker lines
- Under-sink connections & P-traps
- Main shutoff valve (we label it)
- Water pressure & regulator
- Hose bibs & visible pipe condition
- Sump pump (where applicable)
The assessment is visual and noninvasive. It identifies visible risk factors and protection opportunities but does not guarantee that plumbing components will not fail, and does not detect concealed defects inside walls, floors, or underground. It is not an engineering, code, or certification inspection.

Common Questions
Questions homeowners ask
How much does installation usually cost?
Most 4-bed, 3-bath homes are about $2,000 installed — that's 12 sensors, one of them free. A typical 2-bath home is about $1,850. Essential — the shutoff, hub, and flow monitoring without room sensors — is $1,450. We count your exact number together at the free assessment, so you have your final price before any work begins. City permit and inspection are included.
Do I need a monthly subscription?
No. The system includes a free app for self-monitoring with no subscription required. Water Protection Plus is an optional membership if you'd like professional monitoring and member benefits.
Will the system work if my Wi-Fi or power goes out?
Yes. The automatic local shutoff is designed to work without WiFi, internet, or power — that's the primary protection. App alerts and remote features need connectivity, but the valve can still close on a detected leak on its own.
Does this guarantee I'll never have water damage?
No. No system can promise that water will never escape or that damage can never occur. What it does is detect leaks early and shut off the main supply automatically to help limit the amount of water released and reduce the severity of a loss.
Can the system reduce my insurance premium?
It may. Some California carriers describe discounts for qualifying leak-detection or automatic-shutoff devices, but eligibility and the amount vary by carrier and policy. Your insurer makes the final decision; we provide the installation documentation.
How many sensors does my home need?
It depends on your home's layout and the water sources you want to protect. We recommend a sensor count at your free assessment and confirm it with you before installing.
Does my water agency offer a rebate?
Possibly. SoCal Water$mart currently describes rebates starting at $100 for qualifying flow-monitoring devices, subject to agency, model, and available funding. We'll help you check eligibility.
What happens if my main water line is difficult to access?
We'll assess it in person. Unusual access, underground or in-wall runs, or a failing existing shutoff may require additional work, which we quote before starting so there are no surprises.
How long does installation take?
Most standard installations are completed in a single visit. Your assessment will confirm the expected time for your home.
Who installs the system?
A licensed installer — our own M. Fitts Construction team (CSLB #1098070), with a licensed plumber brought in when a job calls for one. Either way, we design the system, finish the install to a construction standard, and run the Walkout Test before we leave — never a drop-shipped kit.
What does the free assessment include?
A visible-risk inspection, water-pressure check, main-shutoff identification and labeling, recommended shutoff and sensor placement, a written Water Risk Report and Emergency Water Action Plan, an installed-price recommendation, and a savings check. It's visual and noninvasive, with no obligation.
What is Water Protection Plus?
An optional membership ($15/month or $150/year) that adds professional dashboard monitoring with a defined notification procedure, an annual system health check and plumbing inspection (one scheduled visit per membership year), member repair and remodel pricing, and priority reconstruction scheduling. It is not an emergency-response or guaranteed-dispatch service.
What about water from the roof, drain, sewer, fire sprinkler, pool, or irrigation?
The system protects your home's domestic water supply — the water that flows through your main line. It cannot stop water from sources not controlled by that main valve, such as roof leaks, drain or sewer backups, fire-sprinkler systems, pools, and outdoor irrigation, which usually tees off before the house valve — unless you add the irrigation protection add-on, which puts its own FlowSmart shutoff and leak detection on your sprinkler line (see “It's not just waiting for a leak” above).
The best water-damage repair is the one you never need
Protect your home, your belongings, and your peace of mind — before a small leak becomes a big problem.
