Here’s a step by step guide to fixing a loose kitchen faucet:

Step 1:  Turn off the water supply:

To fix a loose kitchen faucet, you will need to turn off the water supply.  If you don’t do this, you may damage your pipes or flood your home.  Make sure to turn off the water at the main supply valve, then open up all of your faucets and let them drip until they’re all empty.

Step 2:  Take off the handle and stem assembly:

Remove the handle and stem assembly with a screwdriver or wrench.  Once this is removed, you’ll be able to see the mounting nut and washer that may be causing your leaky faucet.

Step 3:  Loosen the mounting nut If the washer is worn out or damaged, take it out and replace it with a new one. If there isn’t any visible damage, try loosening up the mounting nut. If the nut is too tight, it may be the cause of your leak.  If this doesn’t work, move on to Step 4.

Step 4:  Replace the stem assembly:

If your stem assembly is worn out or damaged, you will need to replace it. Some stem assemblies can be replaced by simply unscrewing them from the faucet body.  Other assemblies require you to remove a retaining nut first. To get a replacement part for your faucet, take off the handle and call up your local hardware store or go online and search for a replacement part for your specific model of faucet.
