According to the EPA, even just one drip per second adds up to the equivalent of 180 showers per year. One easy temporary fix for this kind of leak you can try while you wait on a plumber is replacing your aerator, located right inside the faucet. You can pretty easily replace the aerator with a towel and wrench.

If you’re lucky, you can fix your leaking faucet by simply tightening the nut under the handle. Don’t crank it hard, though. If snugging it up doesn’t solve the problem, turn off the water and remove the nut to repair the faucet.
