I live in a two story house with two bathrooms, one upstairs and one down. From time to time the kitchen faucet will just stop giving water. We can turn on all the other faucets and they give water just fine. Most the time if we turn on the bathtub faucet or the washing machine then the kitchen faucet will begin giving water again. I tried that today but got no response from the kitchen faucet at all. Can anyone help?
