The Helix Water District has rolled out a new smart leak detector rebate program. Helix and Sweetwater Authority customers can get a rebate of up to $100 when they purchase a smart leak detector. The detectors sync to smartphones, allowing customers to monitor water use 24/7 via smartphone and the devices notify customers of leaks and water consumption amounts. There are two types of smart leak detectors: plumbed devices and external devices, according to Helix. Plumbed devices are plumbed into your existing water lines. Most of these devices can automatically shut the water off at their point of installation, or allow you to shut your water off remotely, in case of a leak.
