Using your Black Mica Shower Mixer is easy. Simply turn the handles to adjust the water temperature and flow according to your preference. For the best performance, make sure the water supply valves are fully open. When not in use, turn off the mixer properly to avoid leaks. To keep it in good condition, clean it regularly with a mild soap and a soft cloth. Avoid using abrasive cleaners as they may damage the finish. If you notice any issues like leaks or reduced water flow, check the connections and call a professional if needed.
