Using your Brizo Kintsu Single - Handle Lavatory Faucet is easy. Just turn the single handle to adjust the water temperature and flow. When installing, make sure your sink has a single hole and the deck thickness is up to 3 inches. Remember, the drain needs to be ordered separately. For maintenance, wipe the faucet regularly with a soft, damp cloth to keep it looking shiny. Avoid using abrasive cleaners as they can scratch the high - quality brass finish. The ceramic cartridge is durable, but if you notice any issues with the water flow or operation, it's best to contact a professional plumber. You can choose between the 1.5 GPM and 1.2 GPM models based on your water usage needs, both offering a splash - free experience.
