I have a delta 117-dstwithout spray kitchen faucet and it leaks from the base of the spout where it swivels on the base and also from under the sink where the tubing passes through(no damages). And also drips from the nozzle. Only had it for 21/2 years. The earlier faucets were easy to dismantle and repair. Need a answer as soon as possible. Wife needs to use the sink. Can you help me?
