Using your Brizo Allaria 13 - inch Wall Mount Shower Arm and Flange is a breeze. First, find a suitable spot on your bathroom wall. Use the 1/2 - inch NPT threads to securely mount the shower arm and flange. Once installed, attach your showerhead. When using, simply turn on the water and enjoy the optimal water flow and coverage provided by the 13 - inch length. For maintenance, regularly wipe the fixture with a soft, damp cloth to keep it clean. Avoid using abrasive cleaners as they can damage the brass finish. If you notice any signs of corrosion or damage, contact Brizo's customer service. Remember, this shower arm and flange pair well with other Allaria Bath Collection items, so feel free to mix and match to create your dream bathroom.
