The subtle “drip, drip” of a dripper is a visual magnet to any bird. When they see the ripples across the surface of your birdbath, they are drawn to it and stay a while! Each dripper comes with our exclusive custom dripper valve that regulates the flow of water from your outdoor faucet or a recirculating pump. Just one drip per second, one pint of water per hour, turns your birdbath into an attractive gathering place for your feathered friends. In areas where water conservation is critical, consider a Water Timer to turn the dripper on and off automatically. Comes with 50′ of tubing, regulating valve, faucet fitting, and a Y valve.
