What is the main purpose of a booster pump illustrated in a residential plumbing system using a RAFSUN booster pump to increase water pressure and flow rate. The image shows a technician adjusting a booster pump with a pressure tank and gauges, while household water outlets such as a shower and kitchen faucet deliver strong, consistent water flow. This demonstrates how a booster pump solves low water pressure problems by elevating insufficient pressure to a stable level, improving daily comfort, system performance, and water supply reliability throughout the home.
