A leaky faucet might seem like a small annoyance, but over time, those steady drips can waste hundreds of litres of water and raise your utility bills. In many BC homes, leaky faucets are among the most common plumbing issues—and fortunately, they’re often easy to fix when you understand the root causes.
This guide explains the common causes of leaky faucets, how to stop them, and when it’s time to call in a professional.
Why Fixing Leaky Faucets Matters
Even a small leak can make a big impact. A faucet dripping once per second can waste over 3,000 litres of water each year. Beyond the environmental cost, leaks can damage fixtures, promote mould growth, and cause mineral buildup in your plumbing system.
Fixing a leaky faucet promptly saves water, reduces long-term damage, and keeps your home running efficiently.
The Common Causes of Leaky Faucets
Understanding what’s behind your leaky faucet is the first step to solving the problem. Here are the most frequent causes homeowners encounter:
1. Worn-Out Washer
The washer inside your faucet forms a seal to stop water flow when the tap is turned off. Over time, this washer can become worn, stiff, or cracked due to friction and pressure. Once it loses its shape, water starts to drip even when the handle is tightly closed.
Solution: Replace the washer with a new one that matches your faucet model. Always turn off the water supply before disassembling the faucet.
2. Damaged O-Ring
An O-ring is a small rubber ring that holds the faucet handle in place and prevents leaks. If it wears out or loosens, you might notice water seeping from the handle area.
Solution: Replace the damaged O-ring with a new one. This is a simple, inexpensive fix that can often be done in minutes.
3. Corroded Valve Seat
The valve seat connects the faucet to the spout. When water minerals build up or corrosion develops, it can cause leaks around the base of the faucet.
Solution: Clean or replace the valve seat. Using a seat wrench and proper cleaning tools can help remove buildup and restore the seal.
4. High Water Pressure
While strong water pressure is nice for showers, it can stress your plumbing system. When pressure is too high, it can force water through small openings or cracks, causing leaks in faucets and pipes.
Solution: Check your water pressure using a pressure gauge. If it’s above 80 psi, contact a licensed plumber to install a pressure regulator. You can find reliable professionals at Home Services BC.
5. Worn Cartridge or Ceramic Disc
Modern faucets often use cartridges or ceramic discs instead of traditional washers. Over time, these parts can wear out or become clogged with sediment, leading to drips and inconsistent water flow.
Solution: Replace the cartridge or disc based on your faucet’s make and model. Regular cleaning can also prevent sediment buildup.
6. Loose or Worn Parts
Frequent use can loosen screws, nuts, and seals within the faucet assembly. When these parts no longer fit tightly, small leaks can appear around the handle or spout.
Solution: Tighten any loose parts carefully, avoiding over-tightening, which can cause further damage. Replace worn-out components as needed.
How to Fix a Leaky Faucet: Step-by-Step Guide
Before you start any repair, turn off the main water supply and plug the drain to avoid losing small parts. Here’s a basic guide to fixing a standard faucet:
- Identify the Type of Faucet – Determine if it’s a compression, cartridge, ball, or ceramic disc faucet.
- Disassemble the Faucet – Use an adjustable wrench or screwdriver to remove the handle and stem.
- Inspect and Replace Damaged Parts – Look for worn washers, O-rings, or cartridges and replace them with new ones.
- Clean Mineral Deposits – Use vinegar or a descaling solution to clean buildup inside the valve seat.
- Reassemble the Faucet – Put the parts back together securely.
- Turn the Water Back On – Slowly open the valve and test the faucet for leaks.
If the faucet still drips, you may need professional assistance.
Preventing Future Faucet Leaks
Once your faucet is fixed, regular maintenance helps prevent future problems. Here are some simple ways to keep leaks from returning:
- Avoid turning faucets off too tightly.
- Clean aerators and spouts monthly to remove mineral deposits.
- Check for small leaks regularly and fix them right away.
- Have your water pressure tested annually.

Regular maintenance not only extends the life of your faucets but also ensures your plumbing system runs smoothly year-round.
