Our Delta kitchen faucet has been dripping for weeks..er, months. Each drip is the resounding echo of money going down the drain. It is also environmentally irresponsible. Our fix was to put a sponge under the drip so the sink would quit imitating a bass drum. I dreaded replacing the washers but finally decided to do it only to find that mineralization had frozen the screw which holds the hand to the faucet so tightly that I thought I’d break the handle getting it off. I soaked it in vinegar for days and, eventually, it broke free. That’s when I discovered you cannot replace the washers. Delta uses a cartridge which you can from Amazon for $20 or HomeDepot for $25ish. When I went to HomeDepot, the kind salesperson suggested that I contact Delta because they warranty these things. Sure enough, I called Delta today and in under 3 minutes a free replacement cartridge is on its way. In 7-10 days, our drip will be repaired. I cannot believe I put this repair off so long!
