Watts 0004640 Wash Machiner
The Watts 0004640 (Model A2C-M1 IntelliFlow) is a necessary upgrade for any residential laundry setup seeking to mitigate the risk of catastrophic water damage from burst inlet hoses. This automatic washing machine shutoff valve utilizes an advanced electronic control system that monitors the current flow of the appliance. By sensing when the washing machine is in a cycle, the A2C-M1 automatically opens the hot and cold water supplies, ensuring pressure is only present when required. Once the cycle finishes and current drops, the unit de-pressurizes the hoses by closing the valves immediately. For added protection, the included floor-mounted leak sensor triggers an instantaneous shutdown if moisture is detected near the base of the machine. Designed for 1/2 inch sweat connection installations, this unit supports a maximum pressure of 150 psi and handles up to 15 amperes, making it a reliable choice for professional contractors installing flood prevention systems.
Key Benefits
- Smart Current Sensing: Automatically detects the washing machine’s operational state to manage water flow without manual intervention.
- Leak Detection: Includes a dedicated floor sensor that closes valves the moment water is detected to prevent flooding.
- Hose Pressure Relief: Minimizes wear on flexible rubber or braided steel hoses by keeping them de-pressurized when the machine is not in use.
- High Compatibility: Features 1/2 inch sweat inlets and a replaceable internal strainer screen to protect the mechanical components from debris.
- Safe Operation: UL listed and designed for 120V/60Hz standard 15A circuits.
Common Questions
Does this work with 240V stacked laundry units?
The base A2C-M1 is designed for 120V appliances. For 240V or 220V units, you must use the optional A2-IntelliTimer accessory to bridge the electrical signal.
Where should the leak sensor be placed?
For maximum effectiveness, the water sensor should be placed on the floor directly behind or underneath the washing machine where water would first accumulate during a leak.
Can I use this for other appliances like a dishwasher?
No, this device is specifically calibrated for the current draw profiles of washing machines. Using it for other appliances is not recommended by the manufacturer.
