A leaky garden hose wastes water and creates sloppy puddles where you don't want them. You don't have to throw out your hose when a simple repair will stop the leak. To prevent damage to water hoses, always roll them up when they're not in use. Avoid running over a hose with your vehicle or a garden tractor. In cold weather, allow the hose to warm and thaw before you attempt to roll it up. Store hoses inside in winter.
Cut out the damaged section of hose. With the box blade or knife, slice straight down through all layers of the hose on both sides of the damage. For a pin-hole leak, cut out at least 1 inch of hose.
Slip a hose clamp onto each cut end of the hose.
Insert one end of your hose repair connector in the end of each section of hose. Wiggle the plastic tube back and forth to seat it firmly in the hose.
Tighten the hose clamps with the screwdriver.
