Using this shower set is easy. First, connect the single hose to the appropriate water source. You can adjust the water flow and temperature to your preference. The overhead shower head provides a wide - spread water coverage, while the handheld shower spray allows you to target specific areas. When using the handheld spray, hold it at a comfortable angle. For maintenance, regularly clean the shower head and spray nozzles with a mild cleaner to prevent clogging. Avoid using abrasive materials that could scratch the brushed nickel finish. Also, check the connections periodically to ensure there are no leaks. If you have any issues with the water flow or the set doesn't seem to be working properly, refer to the WELS certification information or contact customer support.
