Over time garden hoses may develop tears and cracks or spring leaks. Ultraviolet light from the sun also plays a big role in weakening the integrity of the hose. Frequently, the damage is most observed near the end of the hose where the fittings are. Rather than throw the hose out, you can repair its end to make it like new. You may even get several more seasons out of your hose before it needs to be replaced.
Measure the inside diameter of your garden hose to ensure you use the correct garden hose repair fitting. The inside diameter will be either 5/8 or 3/4 inch.
Take a utility knife and cut through the garden hose a few inches before the damaged portion of the hose. Ensure the cut is clean and straight.
Slide the hose clamp over the cut end of the garden hose and slide it several inches up the hose to move it out of the way for the time being.
Push the cut end of the garden hose over the barbed end of the hose repair fitting. Twist the hose as you push, if you have a hard time pushing the hose over the barb. Ensure you use the right repair fitting for the end you are repairing--either male or female.
Slide the hose clamp over the portion of the fitting that is inside the hose. Tighten with a screwdriver to clamp the hose tightly to the barb.
