Our kitchen sink makes this loud somewhat high pitched annoying sound whenever I turn it on. Sometimes the water doesn't flow out, it sometimes glops out as if there is way too much water trying to come out at once. Once in a while I can turn the flow down or move the spout around and it will temporarily fix the problem for a few minutes. I have replaced the entire faucet and sprayer but I still have the problem. Any suggestions? Thanks in advance.
