When you need to transfer water for construction or maintenance projects, a water pump will do the job. They’re great for people who need to regularly clean pools and hot tubs. Farmers and ranchers use water-transfer pumps for irrigation. People with ponds and streams often use pumps to move recycled water to sprinkle lawns or crops. Boat owners use water pumps to keep their hulls free and clear of water. And homeowners use water pumps to clean gutters, irrigate gardens, and empty flooded basements.
