Water Leaks Are a Bigger Problem Than You May Realize

Did you know many Orange County cities have begun fining residents who fail to repair a home water leak within 48 hours? Such a quick turnaround may seem unrealistic, especially for notorious slab leaks.

Yet the average Orange County home wastes up to 10,000 gallons of water a year — half the volume of a backyard swimming pool.

Wasting water through leaks isn’t just a money and resource problem; damage from water leaks is the second most common home insurance claim. Slab leaks, or leaks in your concrete slab foundation, can be devastating. They can ruin your home’s foundation, cause rampant black mold infestation, make your home unlivable for months at a stretch, and cost tens of thousands of dollars to repair.

Worse, some insurance companies may not cover slab leaks. “Slow leaks” are often considered the homeowner’s sole responsibility. You could be on your own — forced to move out or take out a home loan to cover the repair.

Smart Leak Detection with Moen Flo

But what if we told you there’s a simple and affordable way to keep your water bill low and detect even a pinhole leak anywhere in your plumbing system — before it causes significant damage?

We’re talking about a smart water leak detector, a Wi-Fi-enabled device that attaches to your plumbing and monitors water use in your home — including tiny increases in water use or activity in your pipes due to pinhole leaks.

The best of the breed is the Moen Flo Smart Water Monitor & Shutoff. In this blog, we’ll talk about leak detectors in general, and then specifically about the Moen Flo.

Why Automatic Shut-Off Matters in a Water Leak Detector

An inline home water leak detector monitors water flow through a pipeline. That’s useful, but you’re tied to the device. You’ll have to check it often and manually shut down the water to your house if you suspect a problem.

Can you do this within 48 hours, as your city mandates? And what if you’re on a vacation or business trip? You may return to a house flood and not just a leak.

But a smart water leak detector with automatic shut-off turns off the water supply to your home when it perceives a leak. Completely.

It measures gallon usage through an internal mechanical turbine or ultrasonic wave. After a learning period of about a week, it can distinguish everyday water use from any variation, which may indicate a leak.

With an unexpected jump in water use, it shuts off the main water valve to your home. Damage and repair costs stay at a minimum.

How a Smart Water Leak Detector Works

  1. The inline water leak detector is installed on the main water line for your house.
  2. It must also be close enough to an electrical outlet to plug in.
  3. It takes 7-10 days to understand your patterns of water use. Automatic shut-off may be ineffective without this learning period.
  4. Most new inline water detectors connect to Wi-Fi. Their apps give you real-time alerts on your water use. You can set up the water shut-off limit and configure settings for home and away water use.
  5. Many inline water leak detectors also monitor water temperatures and alert you when pipes are close to freezing.

Benefits of a Smart Leak Detector

A leaky faucet can waste 3,000 gallons of water in a year.

According to the EPA, “The average family can waste 180 gallons per week, or 9,400 gallons of water annually, from household leaks. That’s equivalent to the amount of water needed to wash more than 300 loads of laundry. Household leaks can waste approximately nearly 900 billion gallons of water annually nationwide.”

  • Water damage is the second most common home insurance claim.
  • Many Orange County cities now issue fines if leaks aren’t fixed within 48 hours.
  • Upfront investment in a smart water leak detector will pay for itself over the appliance’s life.

Benefits include:

  • Automatic shutoff in case of leak, including slab leaks
  • Lower insurance premiums
  • Ability to control water flow from an app
  • Insight into your daily water use
