Using your Brizo Levoir Single - Handle Lavatory Faucet is easy. Simply turn the single handle to adjust the water temperature and flow. You can get the perfect water flow with a smooth 1.2 GPM, thanks to the hidden laminar flow stream straightener. When installing, make sure the deck thickness is no more than 3 inches as it's designed for single - hole installation. For maintenance, clean the faucet regularly with a soft cloth and mild soap. Avoid using abrasive cleaners as they may damage the high - quality brass finish. The included metal pop - up drain also needs occasional cleaning to prevent clogs. With proper care, your faucet will last a long time and keep your bathroom looking great.
