Without water pumps, achieving a modern, convenient, stable, and pressurized tap water supply would be nearly impossible. Water pumps play a key role in energy conversion and water transport for domestic supply. They resolve the contradiction between the natural tendency of water to flow downward and the human need for water to reach elevated locations with sufficient pressure. As core equipment, they ensure the convenience, comfort, and safety of daily water use. Selecting appropriate pump types and specifications, along with proper installation and maintenance, is essential to ensure the reliability and efficiency of domestic water systems.​
