Using your Brizo Allaria Widespread Lavatory Faucet is a breeze. Just turn the handles you've chosen (which you ordered separately) to control the water flow and temperature. To conserve water, remember that the faucet is equipped with water - efficient technology, so you can use it without worry. When it comes to installation, make sure your deck is up to 3 inches thick and you have a 3 - hole setup, suitable for 6 to 16 - inch installations. And don't forget to order the drain separately, as it's not included. For maintenance, wipe the faucet regularly with a soft cloth to keep it looking its best. Since it's made of high - quality brass, it's durable, but avoid using abrasive cleaners that could damage the finish. This faucet meets California energy standards, so you're using an efficient and reliable product.
