Using this Mica shower mixer is easy. First, make sure your water supply is turned on. Then, simply adjust the handles to get your desired water temperature and pressure. When using, don't force the handles too hard as it may cause damage. As for maintenance, clean the mixer regularly with a mild soap and a soft cloth to keep it looking good. Avoid using abrasive cleaners as they can scratch the brushed gun metal finish. If you notice any leaks, turn off the water supply right away and check the connections. If the problem persists, contact a professional plumber.
