KINGSTON BRASS KS8105ZX Millennium Pot Filler in Oil Rubbed Bronze - Wall Mounted Kitchen Faucet for Easy Cooking & Filling Pots

As other reviewers have pointed out, screws to knob extenders are too short as included with filler. In order to use extenders in knobs, 2 size #10-24 screws are needed. Cheap and simple to purchase from local home improvement store. My husband was able to install them and the extenders easily, and now pot filler works perfectly without leaking, and is quite luxe looking in kitchen. Lower knob controls valve, should be turned off when filler not in use. Upper knob controls water flow once valve has been opened, allowing user to turn water on and off while switching among pots. Dual knob/valve system supposedly prevents leakage.
