When your tall kitchen faucet spray attachment isn't working, the problem is usually caused by mineral deposits in the kitchen faucet head sprayer. Remove the sprayer and soak it in a solution composed of 50% vinegar and 50% water for several hours. Another common cause is a kinked hose under the sink. Single handle kitchen faucet repair. Check to be sure the hose doesn't kink when the sprayer is pulled out to be used.
