Using your Mica 3 - Way Filter Sink Mixer is easy. First, connect it to your 1/4 inch hose filter kit. Then turn on the water as you normally would. You'll start getting purified water right away. When it comes to maintenance, regularly check the connections to make sure there are no leaks. Although it's lead - free and made of high - quality materials, avoid using abrasive cleaners as they might damage the finish. If you notice a change in water flow or quality, it could be time to check the filter (not included). For any warranty - related questions, refer to the downloaded Warranty Guide.
