Water Leak Detection Services

Mercury is partnering with the leading providers of smart water loss prevention technology, Flo by Moen and Flume, AND subsidizing part of the upfront costs for their signature smart water leak detection devices. Mercury will also provide discounts on homeowners insurance at enrollment for using the Flo by Moen device and will keep the discount going as long as it is active. Though Mercury does not currently offer a policy discount for Flume, you will save on the device cost with an instant rebate from Mercury.

Mercury’s smart home insurance is aimed at better protecting homeowners like you from the leading cause of damage to a property – water leaks! Due to water loss, homeowners lose access to their kitchens or bathrooms and, in some cases, be forced to move out of their home entirely for months, but Mercury wants to help prevent that from happening. As a bonus to getting a tremendous deal on smart home water detection products, you’ll also be saving money on insurance and quite possibly, your water bill, too!*

*This program is open to California single-family homeowners with a current Mercury homeowners policy. Both programs have limited quantities and will be handled on a first come/first served basis.

Currently, a discount on insurance is available only for Flo by Moen.


Mercury knows that no two homes or homeowners are alike and that’s why options are great! Mercury is subsidizing the cost for Flo by Moen or a Flume 2 device, you pick which is best for your home.

Flume app on a smartphone screen

Flume 2 works with virtually any water meter and is easily self-installed in minutes. Flume’s app allows users 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, both inside and outside of the home. To date the use of Flume products have resulted in lower water bills and the avoidance of potential catastrophic property damage due to leaks.

Though Mercury does not currently offer a policy discount for Flume, you can purchase your Flume for just $50 (plus tax and shipping) after a $99 instant rebate from Mercury. By purchasing through Mercury’s partner program with Flume, after the device is installed at your home, Flume will rebate an additional $25 back to you, bringing the net cost down to $25 (plus tax and shipping)!
