It's not much to look at, but the battery powered H2Orb from AquaOne Technologies is one of those devices that can prevent disasters from going from bad to downright, "empty your bank account" worse. The H2Orb senses toilet overflows and water leaks, sounding an alarm when either happens and automatically shuts off the water when disaster strikes.
The H2Orb is an electronic water valve that attaches directly to the water valve behind the toilet. The system is designed with a dual sensing system that will not only eliminate toilet bowl overflows, but will detect any type of water leak. A single float sensor hangs inside the toilet tank and monitors for toilet leaks 24 hours a day. When a leak happens, the H2Orb will shut off the water and alert the user of the leak with an audible alarm as will as an icon displayed on the integrated LCD screen. A second sensor can be attached under the toilet seat that senses a potential overflow and shuts off the water supply to the tank. No more water, no possibility of an overflow and no water on the floor.
The whole system operates on a single 3V lithium battery. The easily replacable coin cell battery lasts for an estimated 5 years with an average use of 20 flushes per day. (Battery life may be more or less depending on the number of overflow and/or tank leaks it prevents).
Considering a leaky toilet uses up to 200 gallons of water per day, the equivalent of 10 full loads of laundry, totaling up to 73,000 gallons of water per year (according to California Urban Water Conservation Council), we're convinced the device would be a water wise tech addition to any household. The only problem is AquaOne Technologies's site is one big mess without any clear price and requires a phone call to place an order, a not so online savvy situation if you ask us.
