Using this shower/bath wall mixer is easy. Just grab the pin handle to turn the water on or off and adjust the temperature to your liking. When installing, make sure to follow the instructions in the installation accessories package. For maintenance, wipe it regularly with a soft cloth to keep the polished chrome and matte black finish looking great. Avoid using abrasive cleaners as they may damage the surface. And always check for any signs of leakage periodically to ensure long - term smooth operation.
