3 Steps to Fix a Leaky Faucet in 2026 (and When to Call a Plumber)

A dripping faucet may seem like a small annoyance, but it adds up quickly and can have a major impact on your wallet as well as potentially lead to avoidable damage. 

According to the Environmental Protection Agency (EPA), a single leaky faucet can waste more than 3,000 gallons of water per year. That’s enough to raise your utility bills and put unnecessary stress on your plumbing system.

The good news? 

Most leaky faucets can be fixed with some basic tools and a little know-how. Still, if the issue goes beyond a worn washer or O-ring, it’s best to contact a licensed plumber like Graybill Service Group for lasting results.

Below, we’ll walk through three simple steps for the DIYer in you to stop a leaky faucet. Plus, in the case that things don’t go as planned, we’ll look at a few tips on when it’s time to call in the pros.

Step 1: Identify the Type of Faucet

The first step is knowing what you’re working with. You can’t do the job right if you don’t have the right information at hand. Before you take on the task of fixing your leaking faucet, it’s important to identify the type of faucet. 

• Compression Faucets – Found in many older homes. They have two handles (hot and cold) and use rubber washers to seal water flow.
  
• Washerless Faucets – Common in newer homes. They use cartridges, discs, or ball mechanisms instead of washers. Usually, these feature a single handle.
  

Why this matters: The type of faucet determines what parts may need repair. In other words, a faucet is not just a faucet. It’s important to understand which one you’re working on before you jump in.  A compression faucet often requires washer replacement, while washerless models may need a new cartridge or disc.

Step 2: Gather Tools & Replacement Parts

Once you know your faucet type, get the right tools ready. You wouldn’t bring a golf club to a baseball game, right? Same goes with fixing a leaky faucet. You need the right tools to get the job done right. 

Before you get started, make sure you have these tools in your toolbox ready to go. 

• Adjustable wrench
• Pliers
• Screwdrivers
• Penetrating lubricant (like WD-40)
• Towels or rags
• Replacement parts (O-rings, washers, or cartridges specific to your faucet)

Pro Tip: If your faucet has been dripping for weeks, check the O-ring first. These rubber seals wear down and are one of the most common causes of leaks. Be sure to match replacements to your faucet brand and model for the best fit.

For homeowners in Lancaster and Chester County, Graybill’s plumbing repair services can quickly source and install the right parts so you don’t have to worry about compatibility.

Step 3: Inspect for Other Causes

If swapping out the O-ring doesn’t fix the drip, look deeper. There may be other underlying issues causing the leak. These are three of the most common ones we come across when working with our customers.

• Worn Washers: Rubber washers can deteriorate over time, especially in compression faucets.
• Corroded Valve Seats: These metal components connect the faucet to the spout and can wear out with constant water exposure.
• Loose Connections: Check all fittings and connections for tightness—but don’t over-tighten, as that can cause damage.

Sometimes fixing a washerless faucet may involve cleaning clogged valves instead of replacing parts. If you’re unsure, it’s safer (and faster) to let a pro handle it.

Smart Faucets & Water-Saving Upgrades in 2026

One of the biggest changes we’ve seen happening in the plumbing industry in recent years is the growth of smart plumbing technology. Many homeowners are now choosing to replace older fixtures with smart faucets that feature touchless operation, built-in leak detection, and automatic shut-off.

These upgrades not only make kitchens and bathrooms more convenient but also help conserve water, a top priority as sustainability continues to be a focus in 2025, and provide proactive monitoring before problems become too big. Some smart faucets can even connect to your phone, alerting you if a leak is detected and tracking your water usage in real time.

Pro Tip: If your faucet is older and continues to leak despite repairs, upgrading to a smart, water-efficient model may save you more money in the long run than repeated fixes. Ask Graybill Service Group about faucet replacement options that balance performance, style, and water conservation.

Is Fixing a Leaky Faucet Difficult?
