QUICK TAKE

Leaks account for 9% of household water use, and non-weather water damage is one of the costliest insurance claims in both homes and commercial buildings.

FloLogic’s Ian Greene explains how one smart valve on the main line tackles both, and why insurers, water utilities, and plumbing engineers are starting to require it.

🌱BREAKING GROUND ON BETTER BUILDING

In this episode, Ian Greene makes the case that the most important smart device in a building isn’t the thermostat. It’s the valve on the water line.

[Key Insight #1] One valve protects the whole building

  • What's outdated: Most properties have no leak detection at all. Industry estimates put adoption around 5%, and spot sensors only catch leaks where they happen to sit.

  • The innovation: A flow-based valve installed on the main line, after the meter or a well’s pressure tank. Normal water use starts and stops, while a leak keeps running. When flow lasts longer than normal, FloLogic sends an alert and shuts the water off. Pinpoint floor sensors near washers, toilets, sinks, and ice makers add a second layer.

  • Impact: It catches a leak anywhere in the property and turns a potential “tear down” into a “mop up.” About 1.5% of insured homeowners file a non-weather water damage claim each year, averaging around $15,000.

[Key Insight #2] The leaks your meter can’t see are still waste

  • What's outdated:Running toilets and dripping faucets feel harmless. Many don’t even register on a water meter, and tenants who aren’t sub-metered or homes on wells never see the bill.

  • The innovation: Continuous monitoring through an app makes hidden waste visible so it can be fixed.

  • Impact: Per the 2026 Residential End Uses of Water study Ian cites, leaks are 9% of household water use. A steady 4-ounce-per-minute drip wastes 45 gallons a day, or 16,425 gallons a year.

[Key Insight #3] The market is moving from optional to required

  • What's outdated: Leak detection is usually installed after a disaster, not designed in from the start.

  • The innovation: Pressure is arriving from several directions. Insurers are recommending, discounting, or requiring flow-based valves. The Southern Nevada Water Authority offers rebates. A Texas municipality requires a leak sensor under attic water heaters. Plumbing engineers at the recent ASPE conference are starting to specify it.

  • Impact: Lower premiums, rebates, and more resilient buildings. Water conservation comes along as a built-in bonus.
