Sink Faucet Leaking From Base

When your sink faucet starts leaking from the base, it can be a frustrating and annoying problem. Not only is it a waste of water, but it can also damage your sink and cabinetry if left unchecked. In this article, we'll explore the common causes of a leaking faucet base and provide step-by-step instructions on how to fix it yourself.

Causes of a Leaking Faucet Base

There are several possible causes for a faucet to leak from the base. Some of the most common include:

Loose or damaged O-rings: O-rings are small rubber gaskets that create a watertight seal between the faucet base and the sink. Over time, O-rings can become worn or damaged, which can lead to leaks.
Worn or damaged washer: The washer is a flat rubber or metal disc that sits between the faucet base and the handle. When the handle is turned, the washer presses against the base to create a watertight seal. If the washer becomes worn or damaged, it can allow water to leak.
Loose or damaged packing nut: The packing nut is a large nut that holds the faucet base in place. If the packing nut becomes loose or damaged, it can allow water to leak around the base of the faucet.
Cracked or broken faucet base: In some cases, the faucet base itself can become cracked or broken, which can lead to leaks.

How to Fix a Leaking Faucet Base

Fixing a leaking faucet base is a relatively simple repair that can be completed in a few minutes with the right tools and materials. Here are the steps on how to do it:

Turn off the water supply: Turn off the water supply valves under the sink. These valves are usually located near the base of the faucet.
Remove the faucet handle: Use a wrench or Allen key to remove the handle from the faucet. Be careful not to damage the handle or the faucet.
Loosen the packing nut: Use a wrench to loosen the packing nut that holds the faucet base in place. Be careful not to overtighten the packing nut, as this can damage the faucet.
Remove the faucet base: Once the packing nut is loose, you can remove the faucet base from the sink. Be careful not to damage the O-rings or the washer.
Inspect the O-rings and washer: Inspect the O-rings and washer for any signs of damage or wear. If the O-rings or washer are damaged, they will need to be replaced.
Reinstall the faucet base: Apply a thin layer of plumber's putty to the base of the faucet and reinstall it in the sink. Be sure to align the O-rings and washer correctly.
Tighten the packing nut: Tighten the packing nut until it is snug. Be careful not to overtighten the packing nut.
Reinstall the faucet handle: Reinstall the faucet handle and turn on the water supply valves.

Once you have completed these steps, the leaking faucet base should be fixed. If the leak persists, you may need to call a plumber for further assistance.
