The faucet is about 13 years old. Whenever I turn either the hot or cold handles, the water comes out at a lower rate than usual. However, I can increase the rate of flow by giving the side sprayer a quick squirt and stopping. Why would altering the water's path for a moment do this? Is the side sprayer defective since the pressure is building up inside its line instead of letting it go to the faucet?
