Using your Brizo Invari Widespread Lavatory Faucet is easy. First, make sure the handles are properly installed (you'll need to order them separately). Turn the handles to control the water flow and temperature. For smooth operation, don't use excessive force when turning the handles. When it comes to maintenance, clean the faucet regularly with a mild soap and a soft cloth. Avoid using abrasive cleaners as they can scratch the solid brass surface. Check the ceramic cartridge from time to time. If you notice any leaks, it might be a sign that the cartridge needs to be replaced. Also, make sure the metal pop - up drain is clear of debris to keep the water draining smoothly.
