Ugh. My kitchen sprayer stopped working. I heard and audible crunch one afternoon and it suddenly stopped spraying, but when I turn on the water the unit still drips. I assumed the plastic piece that compresses the coil inside the sprayer handle had broken, so I bought a universal replacement kit. It installed fine, but it didn't work. When I removed the NEW sprayer unit and turned on the water, the line drips a tiny bit. I'm sort of stumped. There's no obvious markings on the faucet set to tell me who the manufacturer is, and there's no obvious way to "get in there" and see if anything's gunked up... It's a single faucet with a knob on either side for hot and cold water. Thoughts?
