The A2C-SC-WB IntelliFlow(R) washing machine smart water shutoff senses your washing machine’s current flow and immediately shuts off the water supply if an inlet hose bursts. Simply scan the QR code on your IntelliFlow, follow the prompts to register it online and connect it to your local WiFi network to enable real-time text and email alerts. This model comes with a wall box for even easier installation. The IntelliFlow valve only allows water to flow into the washing machine when electric current indicates the machine is in use and automatically closes water inlet valves when a water leak is detected. Including an electrical three-prong outlet to receive a washing machine power cable, wall box, leak sensor, a power cord and a replaceable internal strainer screen. Maximum Pressure: 150psi (10 bar). A burst washing machine hose can discharge 500 gallons of water in one hour, causing catastrophic damage to homes and businesses. Install peace of mind with IntelliFlow.
