So I discovered a puddle underneath my kitchen sink. The drain looks fine. It appears as if the leak is emanating from somewhere in the faucet enclosure. Look at all of the rust. When I run the faucet there is a very slow drip that runs down the flexible metal hose. Water drips off of the weight. Should I look to replace a washer or just replace the whole assembly. Moen? So much for "buy it for life".
