How to Fix a Leaky Faucet, Canadian Style

A leaky faucet is one of the most common household plumbing issues in Canada. Most leaks are caused by worn internal components and can be fixed in under an hour with basic tools. Left untreated, even a slow drip can waste thousands of litres of water per year and increase your utility bills.

This guide explains how to fix a leaky faucet, step by step, based on the type of faucet in your home.

Why Do Faucets Leak?

Faucets leak when internal sealing components can no longer form a watertight seal. Over time, normal use, water quality, and temperature changes cause parts to wear out or shift.

Common reasons faucets leak include:

• Worn washers and O-rings
  Rubber components harden, crack, or flatten with age, allowing water to pass even when the faucet is closed.
• Cartridge wear or damage
  In cartridge and ceramic disc faucets, internal cartridges can crack or lose alignment, causing a steady drip.
• Mineral buildup from hard water
  Calcium and lime deposits prevent seals from seating properly, especially common in many Canadian municipalities.
• Loose or misaligned components
  Vibration from daily use can loosen internal parts, creating small gaps that lead to leaks.
• Freeze-thaw stress
  In colder climates, temperature fluctuations can accelerate seal failure, particularly in older plumbing systems.

Understanding the cause of the leak helps you choose the correct repair and avoid replacing parts unnecessarily.

💡 Fact: Just one drip per second wastes over 3,000 gallons of water every year, which is a real hit to your water bill.

Tools and Parts You Will Need

• Needle-nose pliers
• Utility knife (for cutting old O-rings)
• Faucet repair kit with washers, O-rings, and cartridges
• Seat wrench (for damaged valve seats)
• Silicone grease or plumber’s grease (always apply plumber’s grease to seals)
• Towels and a small bucket to catch water
• A rag or sink stopper to prevent losing small parts down the drain

Parts are readily available from plumbing suppliers and retailers such as Home Depot.

Step 1: Shut Off the Water Supply

Before starting any faucet repair:

• Turn off the hot and cold shut-off valves under the sink
• Open the faucet to relieve pressure
• Place a towel or plug in the drain to prevent losing small parts

If there are no local shut-off valves, turn off the main water supply to the house.

Step 2: Identify Your Faucet Type

Most Canadian homes use one of these four faucet types. Correct identification is critical before buying parts.

👉 PRO TIP: Take old faucet parts to your local hardware store to match exact replacement parts.

Compression Faucet

• Two separate handles (hot and cold)
• Common in older homes
• Leak cause: worn rubber washer or O-ring

Cartridge Faucet

• One handle that moves up/down and side-to-side
• Leak cause: worn cartridge or seals

Ball Faucet

• Single handle with a rounded internal ball
• Leak cause: worn cam, springs, or ball assembly

Ceramic Disc Faucet

• Smooth handle movement
• Leak cause: damaged seals or cracked disc cartridge

Step 3: Fix the Leak by Faucet Type

Compression Faucet Repair

Cause: Worn washer or O-ring

Steps:

1. Remove the handle and valve stem
2. Replace the rubber washer at the base
3. Replace the O-ring if cracked or brittle
4. Reassemble and tighten snugly, not overtight

This is the simplest faucet repair and often costs only a few dollars.

Cartridge Faucet Repair

Cause: Worn or cracked cartridge

Steps:

1. Remove the handle and retaining clip
2. Pull out the cartridge
3. Install an identical replacement cartridge
4. Reassemble and test

Tip: Bring the old cartridge to the store to ensure a correct match.

Ball Faucet Repair

Cause: Worn seals or springs

Steps:

1. Remove the handle and ball assembly
2. Replace the cam, springs, and seals using a repair kit
3. Reinstall the ball and handle carefully

Ball faucets have more internal components and require extra care during reassembly.

Ceramic Disc Faucet Repair

Cause: Dirty seals or damaged ceramic disc

Steps:

1. Remove the handle and cartridge
2. Clean mineral buildup from seals
3. Replace seals or the full cartridge if cracked

Ceramic disc faucets last longer but replacement parts cost more than other types.

Step 4: Turn Water Back On and Test

• Slowly turn the shut-off valves back on
• Open the faucet fully
• Check for leaks around the handle and spout

If the faucet still drips, the valve seat or faucet body may be damaged.

When to Call a Plumber

Call a licensed plumber if:

• The faucet body is cracked
• The leak continues after replacing parts
• Shut-off valves are seized or leaking
• You cannot identify the faucet type

In some cases, replacing the entire faucet is more practical than repeated repairs.

Conclusion

Fixing a dripping faucet isn’t just about saving money; it’s about reducing water waste and preventing long-term damage. With the right tools and a little patience, you can repair most faucet leaks yourself.
