To repair a leaky kitchen faucet in a mobile home, gather necessary tools and materials. If the leak is caused by a loose handle, tighten the screws. For a leaky valve, replace the washer. If the leak is from the stem, replace the stem assembly. If the aerator is clogged, remove and clean it. For more complex repairs, refer to a licensed plumber or use online resources for assistance. Remember to turn off the water supply and take safety precautions like wearing safety glasses.
