Hi Elizabeth, Thank you for your question. To make your repair you will need to first remove the handle. Place the palm on your hand on top of the handle , push down and turn counter-clockwise. This should remove the top portion of the handle. Once this cover is off you will see a screw, remove this screw and the handle will come off. Underneath the handle is the bonnet nut that holds in the stem assembly and a seat and spring in place. Once the bonnet nut is removed you can replace the RP1740 stem assembly and RP4993 seats and springs to stop the leak. I have attached a parts breakdown of a similar faucet model below to help you with the repair.
