Using this Brizo Beauclere Sensori Volume Control Trim with Lever Handle is easy. First, make sure you've ordered the rough separately as required. The rough can fit different wall thicknesses, and the RP100304 can extend the installation depth. When installing, follow the standard bathroom shower installation procedures. To use, simply turn the lever handle to adjust the volume of the shower components. You can control each part independently without the need for a diverter. For maintenance, regularly wipe the trim with a soft, damp cloth to keep it clean. Avoid using abrasive cleaners as they may damage the finish. If you notice any leaks or malfunctions, contact a professional plumber right away.
