Whining kitchen faucet when using sprayer

replace faucet washers and diverter valve part.

first move hose around while spraying does noise change? noise is sometimes from interior of hose vibrating, hoses detoriate over time.

moving hose with hot water spraying should help rule this out

I had a similar problem a few years ago and it turned out to be a swollen gasket at the place where the spray head attached to the hose. The hole in the center of the gasket had closed down so much that the restriction prevented enough flow to fully toggle the diverter valve.

I went through changing the diverter valve before I figured out it was just that damn gasket, enlarged its center hole a bit and things got good again fast.

A dopeslap to the back of the head usually helps. %->
