This device, typically a small plastic disc with a precisely sized hole, controls the rate at which water enters the appliance. It’s usually located at the end of the fill hose, either where it connects to the water supply or the washing machine itself. A common example is a small plastic disc with a calibrated orifice installed within the water supply hose.
By limiting water flow, this component reduces water consumption per cycle, contributing to lower utility bills and environmental conservation. This regulated intake also allows the machine to fill at an optimal rate, preventing overflows and potential damage. Historically, older machines often used larger volumes of water; this device’s widespread adoption aligns with modern efficiency standards and growing awareness of water scarcity. This regulated flow can also improve detergent dissolution and distribution, potentially enhancing wash performance.
