If you notice water leaking out from the base of your gold faucets kitchen, the most common problem is a worn O-ring. In addition to the worn out o-ring, mineral deposits can also prevent the faucet from working properly. To fix the leak, you can install a new O-ring on the stem of the faucet. For single-handle faucets, you can replace the O-ring by inserting it into the stem. If you've ever replaced an O-ring, you know how important it is to maintain the water flow in your kitchen.
