How do you fix one slow running faucet which worked perfectly before but not after a new water heater was installed and all other faucets work fine?
Check the screen in the end of the neck. Very often rust and sediment are dislodged when the water system is shut off. If not that then possible in the valves themselves. Depending on the age of the pipes you might have to clear them several times. You can take the valves out and VERY slowly open the shut off valves just enough to let water come out of the top of the faucet. This should flush out anything that may be loose in the line.
