Using your Eric Ceiling Shower Arm is easy. First, make sure to turn off the water supply before installation. Then, attach the shower arm to the ceiling fitting tightly. Once installed, turn the water back on and check for any leaks. When using, you can adjust the water flow as you like. For maintenance, clean the shower arm regularly with a mild soap and water solution. Avoid using abrasive cleaners as they can damage the black finish. If you notice any issues like low water pressure or leaks, check the connections first. If the problem persists, it's best to contact a professional plumber.
