Mercury Insurance Water Leak Detection Program Aims to Save Water and Money for California Homeowners during Historic Drought

In partnership with Flume, Mercury will provide homeowner policyholders with a smart home device and discount that will help prevent water waste and monitor water usage

LOS ANGELES, March 10, 2022 /PRNewswire/ -- Mercury Insurance (NYSE: MCY) announced it will be subsidizing the cost of smart home water monitoring devices from Flume, providing California homeowner policyholders a way to track their water usage and prevent costly leaks. This water leak detection program is designed to help homeowners save water and money during the ongoing drought.

"Small leaks in your home's pipes and irrigation system can result in an incredible amount of wasted water," said Mercury Insurance Product Manager for California, Adam Bakonis. "Water leaks are preventable and the key is catching them early to minimize the damage. This is achievable through our partnership with the Flume, a simple water leak detection device homeowners install that can discover large, small and in some cases, hidden leaks."

On average, more than 40% of a home's premium in California is attributable to the risk of water damage. Due to a water loss, homeowners may lose access to their kitchens or bathrooms and, in some cases, have to move out entirely for months. 

Mitigating Damage with Water Leak Detection Services

Installing the Flume system will help mitigate water loss before severe damage to the home can occur. Flume works with virtually any water meter and is easily self-installed in minutes. Along with the corresponding app, users are able to view and monitor indoor and outdoor water use from anywhere, at any time. This increased visibility provides complete home protection by catching and alerting users of leaks as they happen, inside and outside of the home. The use of Flume products can result in lower water bills and the avoidance of potentially catastrophic property damage due to leaks.

"Ten months after installing a Flume device, one of our policyholders was out of town when a leak notice was triggered. They called a friend and asked them to check on the home," said Bakonis. "A supply line ruptured and flooded the first floor. Though there was damage, the loss would have been worse if the leak had not been discovered until the person returned home. A significant amount of additional water would have escaped if mitigation efforts started late, making a potential impact over a larger area which could have resulted in the removal of more materials and potentially more disruption for the insured."

Flume digitizes 4.9 million gallons of water per day, and insights from the smart water detection device has found that:

  • More than 34% of Flume users find a leak within one week of installation of the device
  • More than 70% of all Flume users find a leak over time
  • Flume customers reduce water consumption by at least 10% year over year after installation
  • 66% of Flume users are able to reduce their water bill
  • 80% of Flume users were more aware of their water use after installing Flume and stated that Flume changed their water behavior

After a $99 instant rebate from Mercury, policyholders will pay just $50 at checkout (plus tax and shipping) and they will be eligible to receive an additional rebate of $25 after installing Flume. This brings the net cost down to $25 (plus tax and shipping).

Benefits of Water Leak Detection Programs

Following are key benefits from Mercury's water leak detection program:

The territory and age of a home are primary factors for susceptibility to water leaks

During the past decade, Californians have seen their home values increase at a historic rate. According to the real estate industry trade publication, "Realtor Magazine," the median California home value is projected to grow to more than $1 million by September 20301. The current and future investments of many homeowners, however, may be at risk. When selling a home, water leak damage must be disclosed to potential buyers. California's aging homes are a leading cause of concern as Mercury, one of the largest carriers in the Golden State to offer a water leak detection device discount, reports nearly 50% of single-family homes it insures in California are more than 50 years old, with Southern California skewing the oldest (75% of Los Angeles County; and 55% of Orange County). However, Mercury advises homeowners that water leaks begin to occur well before the half century mark.  

California's ongoing drought is a motivating factor to take action

Slow dripping faucets or irrigation systems only heighten the seriousness of California's ongoing drought. While many believe their home water supply system is leak-free, the average household's leaks can account for nearly 10,000 gallons of water wasted every year, and 10% of homes have leaks that waste 90 gallons or more per day, according to the EPA2. Some California water districts are offering rebates for the installation of water leak detection and shutoff devices3. "Our program, combined with California water district rebates, means some homeowners may be eligible for rebates that would cover the entire cost of these devices and their installation. Not only is our program good for the environment, but leaky faucets getting the attention they deserve will save homeowners money on their water bill and insurance," said Bakonis.

Flume offers 24/7 monitoring, leak alerts, and usage data that allows users to understand exactly where their water is going, indoors and out, and compare water usage and savings with neighbors.

Mercury Insurance has a broad array of optional coverages to protect against exposures faced by today's homeowners, including Home Systems Protection, Service Line Protection, Identity Management Services and Home Cyber Protection. Mercury's water leak detection program is available at or by contacting a Mercury agent.
