Hello, I need some help, please. My kitchen faucet has very low pressure when either hot or cold is turned on, but high pressure if the sprayer is on -- why? What is wrong, what do I need to do to fix it? Thanks for your help... :confused:

Tell us the brand and the model number of your faucet, if the sprayer is separate from the faucet spout, remove the Aerator see the Image below, turn on both hot and cold see if the flow is good if is clean the Aerator install and check, Good luck.
