Easy fix, shut-off water at under-counter angle valves and water meter, pop-out the blue and red insert located on the front of the handle of the faucet, turn faucet on to relieve pressure, loosen allen screw under red and blue insert, pull handle up, remove nut under handle, remove plastic insert gasket and stem under the nut, notice two rubber gaskets.... remove them and the springs behind them and replace, when putting the insides of the faucet back in pay close attention to the notches and grooves,,,, the parts only go back one way....
It also may be noted that in some states such as Texas, the water is considered "hard" and tends to leave a lot of calcium deposits and buildup which affect the ability of the little black gaskets to seal. Before anyone plainly changes the gaskets, pay attention to any possible buildup that would impinge upon the ability of the gasket to seal. If you do have buildup, just use some Limeaway or Kaboom and get rid of it before you replace the gaskets and springs. You may want to try and just clean away the deposits first and then reassemble before heading to Home Depot for the parts..? Anyway the advice above is very helpful. If you don't know what parts the advice is referring to, just head on over to DeltaFaucet.com and get your model and drawings. They're very simple to understand.
Good news, the repair is very simple and cheap, just a trip to Home Depot. The only part that can cause this faucet to drip is a sealed cartridge that has a life time warranty. Disassemble the faucet and take the cartridge to Home depot, they will replace for free no questions asked. Worked wonderfully for me.
