We have a Moen kitchen sink pull-out faucet, and when the water is turned on it leaks from #1 and #2 in the photos. When the water is turned off it stops leaking from #2, but continues to drip from #1 until the water left in that area clears out. The water seem to be originating from #3, near or from the clamp/washer thing that #3 is pointing at. Can anyone help me fix this?
