Fixing a Dripping Single Handle Kitchen Faucet: A Step-by-Step Guide to Repairing Your Faucet Leak

A dripping single handle kitchen faucet is not only annoying but can also waste a significant amount of water. Before diving into repairs, it’s essential to identify the cause of the drip. Most often, the issue lies with the cartridge, O-ring, or seals. In this guide, we will walk you through a straightforward process to fix your faucet.

Identifying the Problem

Begin by observing the faucet while it's in use. If the drip occurs only when the faucet is turned on, the cartridge is likely the culprit. If it drips when off, you may need to check the O-ring or seals.

Required Tools and Materials

Gather the following tools: adjustable wrench, screwdriver, replacement cartridge or O-ring set, and plumbers' grease. Having everything ready will streamline the repair process.

Steps to Fix the Dripping Faucet

1. **Turn Off the Water Supply**: Locate the shut-off valves under the sink and turn them off.

2. **Remove the Faucet Handle**: Use a screwdriver to remove the screw holding the handle in place. Gently lift the handle off.

3. **Access the Cartridge**: Depending on your faucet's design, you may need to remove a retaining nut to pull out the cartridge.

4. **Replace the Cartridge or O-ring**: If the cartridge appears worn, replace it with a new one. If the O-ring is damaged, replace this part instead. Apply plumbers' grease to the new parts to ensure a good seal.

5. **Reassemble the Faucet**: Carefully put everything back together in the reverse order of disassembly. Make sure all parts are secure but avoid over-tightening.

6. **Turn on the Water Supply and Test**: Finally, turn the water supply back on and check for leaks. If everything is sealed properly, the dripping should have stopped.

When to Call a Professional

If you’ve followed these steps and the faucet is still dripping, it may be time to consult a plumbing professional. Persistent leaks can indicate underlying issues with your plumbing that require expert intervention.

Regular Maintenance Tips

To prevent future leaks, regularly check your faucet for signs of wear. Cleaning aerators and ensuring the faucet is properly lubricated can extend its lifespan.
