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 feet of 1/4 inch tubing, regulating valve, faucet fitting and a Y valve. Place it in your birdbath and connect to your outside faucet and the moving water will attract the birds.
