Hi Nancy, Thank you for your question. You will want to replace the stem asembly, seats, and springs on your model P299628LF-BN to stop the drip. The handles are attached with a set screw found on the side of the handle base under the lever portion of the handle. A 3/32 allen wrench will unscrew thw set screw and the handle can be lifted off the faucet. Here is a link to the owners manual for your model which includes the parts breakdown to help you with your repair. http://www.peerlessfaucet.com/customer-support/find-repair-parts/documentation/p299628lf-bn.html?document=mi&documentIndex=0#viewDocument Thanks, Dave
