Kitchen faucett both cold and hot makes a high pitch sound when turned on. Any ideas what the cause could be?

Need more info Brand and model number of the faucet, is it single handle or two handle, Thanks.

In general terms, its usually caused by worn washers, o rings or whatever. It's exaborated by pipes that are not fastened properly.

KeepItSimpleStupid is correct, if you tell us the brand and the model number we will tell you how to replace the washers, thanks.
