How Can I Stop A Leaky Delta Sink Faucet?
Delta faucets have replaceable parts under the handle you need to remove the handle, you will need an allen wrench of correct size pull the handle off next you need to unscrew the cap surrounding the stem that the handle attaches to use a wrench(I’d wrap a towel around the cap so you don’t scratch the chrome) under this is a plastic and rubber gasket over a stainless stem remove these and there will be two black rubber gaskets on springs where the hot & cold water enter I’d use the allen wrench to pop these out—these are what are causing the leak you should be able to buy these replacement parts at you local home improvement store or local Delta wholesaler when installing these new pieces, align them on the allen wrench so you can guide them into there respective holes they then need to be pressed down so the the rubber caps are tight on the springs and not sticking up to far (check the old ones for reference before removing them) then install the stainless stem, it will have a slot
