I am buying a house and the water pressure out of the kitchen sink is less than anywhere else in the house (even the same level). I was told by the builder that is because of the type of kitchen faucet (it is a Moen combination faucet and sprayer..not sure of type). He told me the only way to have the pressure the same was by replacing the faucet with one without the sprayer. Is this true and why would this be? I want to make sure he is telling me the correct information
