Both hot & cold water has no pressure. The kitchen and bathroom are on the same floor in fact right next to each other and the bathroom sink is fine. Please advise:confused:

Shut of your main or the stop cocks under the kitchen sink. Remove the aerator from the spout and inspect it for debris. Remove the faucet stem/valve and also inspect and flush. A friend helping might be a good idea for the next step. With the stem removed, place a towel over the opening and have the friend very briefly open and close the syop cock or main to flush out more junk.
