Using your Brizo Kintsu Widespread Lavatory Faucet is easy. Just turn on the water as you would with any regular faucet. Since the handles are ordered separately, make sure to install them properly before use. When it comes to the drain, you'll need to order it separately and install it according to your sink's requirements. For maintenance, wipe the faucet with a soft, damp cloth regularly to keep it looking shiny. Avoid using abrasive cleaners as they can damage the solid brass finish. Also, since it's CEC Certified, it's already designed to meet environmental standards, but try to be mindful of water usage to make the most of its water - saving features. If you notice any issues with the smooth operation, it might be related to the ceramic cartridge, and you may want to contact a professional for inspection.
