Fix Single Handle Kitchen Faucet Leaking From Neck

Are you experiencing a frustrating leak from the neck of your single handle kitchen faucet? Don’t underestimate the significance of this seemingly minor issue.

Leaky faucets may appear harmless, but if left unrepaired, they can lead to more significant and costly problems. In the case of a single handle kitchen faucet leaking from neck, the situation becomes even more crucial as it directly affects one of the most frequently used fixtures in your home. Ignoring the problem can result in potential plumbing damage, increased water consumption, and increased utility bills. Let’s see how to fix the leak from the neck.

How To Identify The Leak From The Neck?

Identify The Leak From The Neck

A leak from the neck of a single handle kitchen faucet can be identified through visible water dripping or pooling around the base of the faucet spout. It may also be accompanied by a continuous or intermittent dripping sound. To confirm the source of the leak, you can perform a simple inspection:

  • Clear the area: Before you begin, make sure the sink area is dry and clear of any items that could block your view or hinder your movements.
  • Observe the base of the faucet spout: Carefully inspect the area where the spout meets the faucet body. Look for any signs of water accumulation, such as moisture, droplets, or water stains.
  • Check for water flow: Watch the area near the spout’s base after turning on the faucet. Water flowing from the joint where the spout attaches to the faucet body is an indication that the neck is leaking.

Potential Causes of The Leak

  1. Loose or worn-out cartridge: The cartridge is a crucial component inside the faucet body that controls the flow of water. Over time, it may become loose, worn-out, or damaged, leading to leaks from the neck.
  2. Damaged O-rings or seals: O-rings and seals provide a watertight seal between different components of the faucet. If these rubber gaskets become deteriorated, cracked, or broken, they can cause water to leak from the neck.
  3. Loose or damaged connections: The connections between the spout and the faucet body, as well as the supply lines, may loosen or develop cracks over time. These loose or damaged connections can result in leaks from the neck.
  4. High water pressure: Excessively high water pressure can put a strain on the faucet components, leading to leaks. This pressure can cause the spout to separate slightly from the faucet body, causing water to leak from the neck.
  5. Faulty installation: Improper installation of the faucet, including incorrect placement or insufficient sealing, can contribute to leaks from the neck. If the faucet was not installed correctly initially, it may develop issues over time.

Step 1: Shut off the Water Supply

Find the water supply valves by the main water line or under the sink. By turning the valves counterclockwise, you can shut off the hot and cold water supplies. To discharge any remaining water pressure, open the faucet.

Step 2: Remove the Handle

Determine the type of faucet handle your single handle kitchen faucet has: lever handle, knob handle, or button handle.

Look for a small screw or set screw securing the handle. Use a screwdriver or Allen wrench to loosen and remove the screw. Gently pull the handle off the faucet stem.

Step 3: Inspect the Cartridge or Valve

Check the cartridge or valve for evidence of deterioration such as cracks, wear, or mineral buildup. Look around the cartridge or valve for a loose or broken rubber seal.

Search for any objects that might be preventing the water from flowing. Consider replacing the cartridge or valve with a compatible replacement part if it has been damaged.

To remove and install the new cartridge/valve, adhere to the manufacturer’s instructions. Make sure the fit is correct and tighten any retaining nuts or screws.

Step 4: Examine the O-ring and Seals

Examine the O-rings and seals surrounding the faucet neck for evidence of wear, cracking, or deformation.

Look for water stains or dampness near the O-rings or seals. Purchase a replacement O-ring or seal that fits the size and model of your faucet. Carefully remove the old O-ring or seal and clean the area. Install the new O-ring or seal, ensuring a tight fit and appropriate alignment.

Step 5: Check the Supply Lines and Connections

Examine the supply lines connected to the faucet for any loose or damaged fittings. Tighten any loose connections using a wrench or pliers.

Look for signs of corrosion or leaks around the connections. If the supply lines are damaged or leaking, consider replacing them with new ones.

Measure the length and diameter of the existing supply lines before purchasing replacements. Follow the manufacturer’s instructions for disconnecting and connecting the new supply lines.

Step 6: Reassemble the Faucet

  • Reverse the steps taken to disassemble the faucet.
  • Place the handle back onto the faucet stem and secure it with the screw or set screw.
  • Ensure the handle is aligned properly and functions smoothly.
