Drip... drip... drip. That persistent sound from a leaking faucet isn't just annoying; it's a sign of a plumbing issue and can waste a surprising amount of water over time. If you're a Vancouver homeowner wondering "Why is my tap dripping?", you're not alone. Fortunately, many common causes are straightforward to understand and sometimes even fix yourself. This post breaks down the usual culprits behind that relentless drip and helps you decide on the best course of action.
Why Is My Tap Dripping? The Quick Answer
A dripping tap in Vancouver is most often caused by worn-out internal components like rubber washers, O-rings, or cartridges inside the faucet handle. Sometimes, excessive water pressure in your home's plumbing or a corroded valve seat (where the washer seals) can also be the underlying issue.
Unpacking the Common Causes of a Leaking Faucet in Vancouver
Let's dive deeper into the specific reasons why your faucet might be dripping:
1. Worn-Out Washer (Compression Faucets)
This is one of the most frequent causes, especially in older faucet types (compression faucets, often with two separate handles for hot and cold).
- How it Works: A rubber washer presses against a valve seat each time you turn the tap on, controlling water flow.
- Why it Fails: Constant friction and pressure wear down the washer over time. Eventually, it doesn't create a perfect seal, allowing water to drip through. Mineral buildup, sometimes a factor with Vancouver's water, can accelerate this wear.
- The Fix: Replacing the washer is often a simple DIY task (more on that below).
2. Damaged O-Ring (Especially Cartridge Faucets)
Many modern faucets, particularly single-handle mixer taps (cartridge faucets), use an O-ring.
- How it Works: This small rubber ring creates a seal, often around the base of the spout or within the cartridge mechanism.
- Why it Fails: Like washers, O-rings can wear out, crack, or become loose over time, leading to drips, often around the handle base.
- The Fix: Replacing an O-ring can sometimes be DIY, but accessing it might require disassembling parts of the faucet handle.
3. Faulty Cartridge (Cartridge Faucets)
Single-handle lever faucets typically use a cartridge – a self-contained valve mechanism.
- How it Works: This cartridge controls both water flow and temperature mixing.
- Why it Fails: The internal seals or the plastic body of the cartridge itself can crack or wear out, causing drips.
- The Fix: The entire cartridge usually needs replacing. While possible for DIY, getting the exact replacement cartridge can be tricky.
4. Corroded Valve Seat
- How it Works: The valve seat is the metal part inside the faucet body that the washer presses against to stop water flow.
- Why it Fails: Water sediments and mineral buildup can corrode the valve seat over time, creating an uneven surface that the washer can't seal properly against, leading to persistent drips even with a new washer.
- The Fix: Cleaning the valve seat might work temporarily, but often it needs to be refaced with a special tool or the entire faucet might need replacement. This usually requires a plumber.
5. High Water Pressure
- How it Works: Your home has a standard water pressure range.
- Why it Fails: If the water pressure is too high, it puts extra strain on washers, cartridges, and pipes. This can force water past seals, causing drips (and potentially more serious leaks elsewhere). Older homes in some Vancouver neighbourhoods might experience pressure fluctuations.
- The Fix: Requires testing your home's water pressure and potentially installing or adjusting a pressure reducing valve (PRV). This is definitely a job for a qualified plumber.
DIY Fix or Call a Vancouver Plumber?
Before attempting any repair, always turn off the water supply to the faucet using the shut-off valves typically located under the sink. If there are no shut-off valves, you'll need to turn off the main water supply to your house.
Consider DIY If:
- You have a simple compression faucet and suspect a worn washer.
- You are comfortable identifying faucet parts and using basic tools (screwdriver, adjustable wrench).
- You can easily find the correct replacement part (washer, O-ring).
Call a Licensed Vancouver Plumber If:
- You're unsure about the cause of the drip.
- You have a cartridge faucet and aren't confident replacing the cartridge.
- You suspect high water pressure or a corroded valve seat.
- You can't turn off the water supply to the faucet.
- You've tried a DIY fix, and the tap is still dripping.
- You're worried about causing further damage.
Don't Ignore That Drip!
While seemingly minor, a dripping tap can:
- Waste Significant Water: Even a slow drip adds up gallons over weeks and months, impacting your utility bill and the environment.
- Cause Stains: Constant moisture can stain your sink basin over time.
- Indicate Bigger Problems: Sometimes, a drip is an early warning sign of high water pressure or other plumbing issues.
- Be Incredibly Annoying: Let's face it, the sound alone is reason enough to fix it!

Conclusion: Stopping the Drip in Your Vancouver Home
A dripping tap is a common household nuisance in Vancouver, but understanding the likely causes – worn washers, O-rings, cartridges, corroded valve seats, or high water pressure – empowers you to address it. Simple fixes like replacing a washer might be within your DIY capabilities, but don't hesitate to call a professional for more complex issues or if you're uncertain. Fixing that leak promptly saves water, money, and restores peace and quiet to your home.
If you're unsure about tackling the repair yourself or suspect a more complicated issue, it's always best to consult a qualified and licensed Vancouver plumber.
