Using your Brizo Invari tub filler is easy. Just turn the single handle to adjust the water temperature and flow according to your preference. When using it, make sure the water pressure is at a normal level to avoid splashing. For maintenance, clean the tub filler regularly with a soft cloth and mild soap. Avoid using abrasive cleaners as they can damage the finish. If you notice any leaks or problems, contact a professional plumber right away. With proper care, your tub filler will keep looking great and working well for years.
