The Sprayer head on my kitchen sink broke, so I went to the store and purchased a new sprayer head. I have replaced these before in other houses, so I didn't think I would have a problem. However, I ended up with 2 problems. When I turn the water on with the faucet, it feels like there is a vacuum for a second and the faucet jerks before the water comes out. At the same time the sprayer head leaks slightly. I have removed the sprayer head several times thinking I had something not screwed on tight, but have not been able to fix the problem. Any help would be appreciated. Dori
