Why Do Faucets Leak?

Why Do Faucets Leak?

Leaky faucets are one of the most common household plumbing issues. They may start as a small annoyance—a pesky drip-drip-drip—but over time, they can waste significant amounts of water and even increase your utility bills. Whether you’re a seasoned plumber or a homeowner looking for answers, understanding the reasons behind a leaky faucet is essential for timely fixes and preventing bigger problems down the road.

Common Causes of a Leaky Faucet

Here are some of the most common reasons faucets start to leak:

1. Worn-out Washers or O-rings

One of the most frequent culprits of a faucet leak is a worn-out washer or O-ring. Over time, the constant friction and pressure can degrade these small yet crucial components. When they weaken or crack, water may begin seeping through the faucet, causing that unwanted drip.

Pro Tip: Replacing washers and O-rings is a cost-effective fix that homeowners can often handle themselves.

2. Corrosion in the Valve Seat

The valve seat is what connects the faucet to the spout. Corrosion can occur over time due to water sediments or mineral buildup, compromising its seal and leading to leaks.

Regular cleaning and maintenance can help prevent valve seat wear. If the corrosion is severe, replacing the valve seat might be necessary.

3. Loose or Damaged Parts

Any loose or deteriorated components like screws or seals within the faucet can also cause leaks. Moving parts are subject to wear and tear over time, loosening connections or causing small gaps that allow water to escape.

4. Water Pressure Issues

If your faucet only leaks at specific times, like at night or after using other water systems in your house, then fluctuating water pressure could be the problem. High water pressure might result in dripping when the water has nowhere to go but through a small, unintended gap.

5. Cartridge Issues

Modern faucets, especially those with two handles, use cartridges to control water flow. Wear and tear on these cartridges can result in leaks, as they may no longer properly regulate the water movement.

Quick Fix: Replacing the faulty cartridge is typically an easy and inexpensive repair.

6. Mineral Deposits

Hard water can lead to mineral deposits around faucet components. Over time, these deposits can interfere with the smooth operation of the faucet, potentially causing leaks.

Preventive Maintenance: Installing a water softener can help reduce mineral buildup and prolong the life of your plumbing fixtures.

7. Aging Faucets

Ultimately, faucets, like any other household fixture, have a limited lifespan. With prolonged use, the wear on the internal components may lead to persistent leaks. If your faucet is decades old, it may be time to consider a replacement.

Why Is Fixing a Leaky Faucet Important?

Ignoring a leaky faucet is never a good idea. Here’s why you should address them promptly:

Water Waste: A faucet dripping once per second can waste over 3,000 gallons of water annually! This isn’t just bad for your wallet but also for the environment.
Higher Utility Bills: The more water wasted, the higher your water bill.
Potential Damage: Over time, the constant dripping could lead to water staining and damage to sinks or countertops.

When to Call a Professional at A Rescue Rooter

While some people may try to fix a leaky faucet themselves, it’s important to know when to call a professional plumber. Here are some signs that you should hire a pro:

Persistent Leaks: If the faucet continues to leak even after being fixed, this could be a sign of a larger underlying issue.
Older Faucets: As faucets age, they become more prone to leaks and other issues. A professional plumber can assess whether it's time for a replacement.
Complicated Repairs: Some faucet repairs require specialized tools or knowledge that only professionals possess.

Having regular maintenance checks by a professional plumber can also help prevent future leaks and extend the lifespan of your

While some minor leaks can be fixed with a few basic tools, it’s always best to call in a professional plumber for bigger or more complex issues. Here are some signs that you should seek help from a professional:

Multiple Leaks: If you have multiple faucets leaking throughout your home, it could indicate a larger plumbing issue that needs to be addressed.
Noisy Pipes: If your pipes are banging or making unusual noises when using the faucet, this is another sign of a larger problem and should be checked by a professional.
Low Water Pressure: A leaky faucet can also lead to low water pressure.

While some faucet repairs are DIY-friendly, others may require professional expertise. If you’ve tried to fix the problem and the leak persists or worsens, it’s time to call in the experts.

The Water Pressure at Home is Dropping

By Robbie Balla • April 28, 2025

Low water pressure is more than just an inconvenience—it can be a sign of a deeper plumbing issue. Whether you’re brushing your teeth, running the dishwasher, or trying to enjoy a relaxing shower, reduced water pressure disrupts your daily routines and could point to hidden problems in your home’s plumbing system. But how do you know when it’s time to call a professional plumber? Here’s a detailed guide to help homeowners and plumbers decide the right course of action when the water pressure starts to drop. Common Causes of Low Water Pressure Mineral Build-up in Pipes Over time, mineral deposits from hard water can accumulate inside your plumbing pipes, reducing the flow of water. Areas with hard water are particularly prone to this problem, and once it starts, it tends to worsen if left unaddressed. Leaky Pipes A hidden leak in your plumbing system can drastically reduce water pressure. Not only does this waste water (and increase your bill), but it can also cause significant property damage if not handled quickly. Clogged Fixtures Sometimes, the issue lies in your faucets or showerheads. Dirt, debris, or limescale can clog fixtures, reducing the water flow. While this is often something you can fix yourself, it’s important to rule out more serious causes. Faulty Pressure Regulator If your water pressure is fluctuating or uniformly low, the pressure regulator might be faulty. This part ensures your water pressure remains at a safe, functional level, so any issues with it need immediate attention. Main Water Line Problems Sometimes, low water pressure originates outside your home. Damage to your main water line, aging utility infrastructure, or municipal water supply issues can affect overall pressure. When Should You Call A Rescue Rooter While some causes of low water pressure are simple enough to tackle on your own, others require the expertise of a professional. Here are some scenarios when calling a plumber—like Rescue Rooter in Southern Ontario—is your best bet: 1. You Can’t Find the Source of the Problem If you’ve checked for clogged fixtures, leaks, or a failing pressure regulator and can’t identify the issue, it’s time to call in the pros. A professional plumber has the tools and experience to diagnose the root cause quickly. 2. You Suspect a Hidden Leak Water leaks aren’t always obvious; they may occur behind walls, under floors, or in your outdoor plumbing. If your water pressure is dropping and you notice damp patches, unexplained water bills, or musty odors, a plumber should investigate immediately. 3. The Entire Home is Affected If the water pressure is low throughout the house (not just in one or two fixtures), this could be a sign of a larger issue, such as a damaged main water line or a problem with your pressure regulator. 4. There’s a Sudden and Significant Drop A sudden drop in water pressure can indicate a burst pipe or other significant damage. This requires immediate attention to prevent further harm to your home. 5.
