That repetitive drip…drip…drip sound from your faucet isn't just annoying—it can waste hundreds of gallons of water a year and cost you real money. Whether it’s a slow leak or a steady stream, a dripping faucet is usually a sign that something inside needs attention.

In this post, we’ll break down:

• What causes a dripping faucet
  

• Common reasons behind leaks
  

• How to fix it yourself
  

• When it’s time to call a professional
  
  

Let’s dive in.

What Causes a Dripping Faucet?

A faucet may start dripping due to one or more internal components wearing out, becoming loose, or getting clogged. Faucets are made up of several small parts—cartridges, washers, O-rings, and seals—that regulate the flow of water.

Over time, wear and tear, water pressure issues, or sediment buildup can cause these parts to malfunction. The result? Water sneaks past when it shouldn’t, creating that all-too-familiar leak.

Common Reasons for Faucet Leaks

1. Worn-Out Washer

Older compression faucets rely on a rubber washer that tightens against a valve seat to stop the water flow. Over years of twisting the handles open and shut, friction and pressure wear the washer down. A hardened or cracked washer won’t seal properly, so water escapes around the spout even when the tap is off.
Fix: Turn off the water supply, remove the faucet handle, and replace the washer with a new one of the same size. Washers are inexpensive and easy to find at any hardware store. Regular replacement keeps older faucets leak-free and saves water.

2. Damaged Cartridge

Cartridge faucets—common in newer kitchens and bathrooms—use a precision part called a cartridge to regulate flow and temperature. Inside, small rubber seals and springs maintain tight control. When these seals deteriorate or the cartridge cracks, water seeps through even with the handle closed.
Fix: Remove the handle and retaining clip, pull out the old cartridge, and insert a replacement. It’s best to bring the old part to the store for a perfect match. If you notice uneven water flow or dripping even after replacing it, check for mineral buildup inside the valve housing.

3. O-Ring Problems

O-rings are tiny but essential for leak prevention. They sit between moving parts, such as the faucet body and handle stem, keeping water contained under pressure. Over time, they can dry out, flatten, or loosen—especially in homes with hard water. This causes leaks at the base of the faucet or where the handle meets the fixture.
Fix: Take apart the faucet handle and inspect each O-ring. Replace any that appear brittle or misshapen. Apply a bit of plumber’s grease when installing new ones to extend their life and prevent future leaks.

4. Corroded Valve Seat

The valve seat forms the seal between the faucet and the spout—an area constantly exposed to water. When minerals and sediment accumulate, they corrode the metal and create tiny gaps that let water escape. A slow drip from the spout, even after replacing washers or cartridges, often points to this issue.
Fix: Clean the valve seat using white vinegar and a soft brush to dissolve mineral deposits. If corrosion is extensive, the valve seat may need to be professionally resurfaced or replaced to restore a watertight seal.

5. High Water Pressure

High water pressure can seem like a luxury—strong showers and fast-filling sinks—but it also stresses plumbing components. Excess pressure can push water past washers, cartridges, and O-rings, causing small but frequent leaks. You might notice drips that come and go, especially at night when municipal pressure rises.
Fix: Check your home’s water pressure with a simple gauge (available at hardware stores). Ideal pressure is between 40–60 psi. If it’s higher, install a pressure-reducing valve (PRV) on your main line. This not only stops faucet leaks but also protects your plumbing system and appliances from damage.

How to Fix a Dripping Faucet Yourself

If you’re handy with a screwdriver and can follow instructions, you might be able to stop the leak yourself. Here's how to approach it:

🧰 Tools You’ll Need:

• Adjustable wrench
  

• Screwdrivers (flat-head and Phillips)
  

• Replacement parts (washer, cartridge, or O-ring depending on faucet type)
  

• Plumber’s grease
  

• Rag or towel
  

• Bucket or bowl (to catch water)
  
  

🔧 Step-by-Step Instructions:

Turn Off the Water Supply
Look under the sink and shut off both hot and cold water valves.

Plug the Drain
Use a sink stopper or towel to prevent small parts from falling into the drain.

Disassemble the Faucet
Remove the handle and take note of how the internal parts are arranged (take a photo if needed). Identify whether it’s a cartridge, ball, disk, or compression faucet.

Inspect and Replace the Faulty Parts
Look for obvious signs of wear: cracked cartridges, flattened washers, broken O-rings. Take the part to a hardware store to get an exact match.

Apply Plumber’s Grease
Lubricate the new parts slightly before reassembling to ensure a smooth fit and prevent leaks.

Reassemble and Test
Put everything back together, turn the water supply on, and test the faucet for drips.

Knowing When It’s Time to Call a Pro

While a dripping faucet might seem like an easy fix, there are times when calling a professional plumber is the smarter (and safer) option. If you're unsure what type of faucet you’re dealing with, or if you've tried replacing parts and the leak continues, it's likely time to bring in an expert.

Visible corrosion, hard water buildup, or a faulty valve seat can indicate bigger plumbing issues that require experience and proper tools. Faucets that are old or rusted may also need complete replacement. And if you’re seeing water leaking under the sink, behind walls, or anywhere it shouldn't be—don't wait.
