Using your Brizo Invari widespread lavatory faucet is easy. First, make sure the handles are installed properly as they need to be ordered separately. Turn the handles to adjust the water temperature and flow. The ceramic cartridge ensures smooth operation. For installation, it's a 3 - hole setup suitable for decks up to 3' thick, and you have a 6 - 16' installation range for flexibility. The included metal pop - up drain helps with water drainage. When it comes to maintenance, wipe the faucet regularly with a soft cloth to keep it looking shiny. Since it's made of durable brass, it should last a long time. Remember, it's CEC certified, so use it knowing you're conserving water. If you notice any issues, contact the authorized retailer or Brizo's customer service.
