What insurance actually wants in Ontario
Carriers are increasingly asking whether a home has automatic leak shut-off before quoting, and several apply a discount when the answer is yes.
Water damage claims are expensive and preventable, which is why a device that shuts the main off on its own is worth real money to a carrier. Ask your agent directly whether they credit an automatic water shut-off valve — most in San Bernardino County do, and the discount often covers a meaningful share of the install over a few years.
We provide the make, model and install details in writing so you have something to send your agent.
What Flo by Moen does
It sits on your main water line and measures pressure, flow and temperature continuously. It runs a nightly micro-leak test that finds drips as small as a drop a minute — the kind you never hear.
When it sees a pattern that looks like a burst line or a fixture left running, it closes the main valve itself and pushes an alert to your phone. You can also shut the house off from the app from anywhere.
It also reports daily water use, which is how a lot of customers first spot an irrigation leak or a running toilet.
Why homes in Ontario are at risk
Older north Ontario homes often have cast iron drains that scale shut, while the new south-end tracts mostly need warranty-adjacent fixture and pressure work.
Cast iron drain failure: Scaled or cracked cast iron backs up repeatedly. We camera it and quote lining or replacement honestly.
We install throughout Downtown Ontario, Euclid Avenue corridor, Ontario Ranch and the rest of Ontario (91758, 91761, 91762, 91764).
How the install works
We install it on the main line just past the house shut-off, then pressure-test and run the system's own diagnostic before we leave.
Typical install is a half day. We handle the plumbing, the Wi-Fi pairing, the app setup and the alert thresholds so it does not nuisance-trip on a long shower or a sprinkler cycle.
We are licensed (CSLB #1146179) and pull permits where Ontario requires them. Pricing is quoted up front before any work starts.
Pairing it with the rest of your plumbing
A shut-off valve limits damage; it does not fix the underlying cause. If your pressure runs above 80 psi, or your supply lines are original galvanized or aging copper, we usually recommend addressing that at the same visit.
We can test pressure, fit a regulator, replace old angle stops and braided supply lines, and flush your water heater while we are on site.
Ontario questions we get
Does my insurance really require a shut-off device in Ontario?
It depends on your carrier and your claim history. Many carriers offer a discount, and some now require an automatic shut-off device on higher-value homes or after a prior water damage claim. Check with your agent — we will supply the paperwork they ask for.
How much does Flo by Moen installation cost?
We quote up front after seeing where your main line runs. Cost depends on access, pipe size and whether a shut-off or pressure regulator needs replacing at the same time. Call 626-386-9105 for a number specific to your Ontario home.
Will it shut my water off by mistake?
We set the thresholds around how your household actually uses water during setup, so normal showers, laundry and irrigation do not trigger it. You can also override or reopen the valve from the app instantly.
Does it work without Wi-Fi?
The leak detection and automatic shut-off keep working. You lose the phone alerts and remote control until the connection is back.
How fast can you install one in Ontario?
Roughly 15 minutes south of Upland.
