Both the hot and cold come out of the same place and flow through a grit screen or aereator just before the water reaches your hands or drinking cup. Try a pair of pliers softened with a paper towel to unscrew, rinse, clean the grit, and replace the screen. The pressure in the line is pressing against the cloddes screen and grit, to cause a delay.
: My 4-year old kitchen faucet has had low water pressure (both hot and cold) for several months. Now, when I turn off the water (either hot or cold - it is a two-handle model), it continues to run for a second or two before stopping. It's like it has a delay on it. Any suggestions on the problem/problems? Thanks!
