My sink runs fine, my sink sprayer runs fine, however, the head is loose and whenever I try to use it or sometimes even when I turn the water on, the head pops right off and water goes everywhere. Is there any way that I can secure it to the hose? Or do I need to replace it? If I have to replace it than will I have to replace the whole system or just the head? Please help, I can't do dishes with water spraying all over the place.
