Using your PAVIA shower set is easy. First, connect the adjustable wall connector to your water supply. Then attach the brass rail with the bracket securely to the wall. Next, connect the 1.5mm PVC shower hose to the handheld shower head and the rail. You're ready to enjoy a refreshing shower. When using, keep in mind to handle the handheld shower head gently to avoid damage. For maintenance, regularly wipe the brushed nickel finish with a soft, dry cloth to keep it shiny. If there's any blockage in the shower head, soak it in a mild vinegar solution for a few hours and then rinse thoroughly. This will help maintain the water flow and the overall performance of your shower set.
