My zipper won work. Whats wrong?
Most zipper problems are Slider problems. This is the piece that moves up and down and actually opens and closes the zipper. Usually, when this wears out, the zipper opens after you close it. Sometimes you can crimp the slider with pliers temporarily making the zipper work. But, what you really need is a new slider because the old one has worn out. This can happen over time or if sand or grit get in the zipper and wear it out. Replacing a slider is not hard. A zipper only needs to be replaced if the teeth or coils are damaged. Replacing a zipper is not an easy task and should only be attempted by a qualified stitching engineer.
