Once installed the water flow is slow at first. I would recommend filling 2-3 glasses with water from the door spout and pouring it out. After that the flow rate evened out.[Note]: Before purchasing, please confirm that your refrigerator has been installed with built-in Filtration and connected with the refrigerator.
