What to Do When You have a Leaky or Dripping Faucet

A leaky or dripping faucet is more than just an annoyance—it can waste gallons of water per day and drive up your utility bills. If left unchecked, small leaks can lead to bigger plumbing problems down the road. Understanding the causes of a dripping faucet and knowing when to DIY or call a professional can save you time, money, and frustration.

Common Causes of a Leaky or Dripping Faucet

If you’re dealing with a leaky or dripping faucet, it’s important to identify the cause. Here are the most common reasons:

1. Worn-Out Washers and O-Rings

The washer and O-ring create a seal that prevents water from leaking. Over time, they can wear out, causing the faucet to drip.

2. Corroded Valve Seat

The valve seat connects the faucet to the spout. Corrosion and mineral buildup can prevent it from sealing properly, leading to leaks.

3. High Water Pressure

Excessive water pressure can force water through small openings, even when the faucet is turned off.

4. Loose or Damaged Parts

With frequent use, faucet components can loosen or break, leading to persistent dripping.

5. Worn-Out Cartridge

If you have a cartridge faucet, the internal cartridge may be damaged, leading to leaks even when the faucet is shut off.

How to Fix a Leaky or Dripping Faucet

If you’re comfortable with DIY repairs, follow these steps:

Step 1: Turn Off the Water Supply

Before making any repairs, shut off the water supply to the faucet. Look under the sink for the shutoff valves and turn them clockwise.

Step 2: Disassemble the Faucet

Use a screwdriver and wrench to carefully remove the faucet handle and access the internal parts.

Step 3: Inspect and Replace Parts

If the washer or O-ring is worn out, replace it with a new one.
If you notice corrosion on the valve seat, clean it with vinegar and a brush.
If the cartridge is damaged, replace it with a matching part.

Step 4: Reassemble and Test

Put the faucet back together, turn the water supply back on, and check for leaks.

When to Call a Professional Plumber for a Leaky or Dripping Faucet

While minor leaks can often be fixed at home, some issues require professional help. Call a plumber if:

The leak persists after replacing washers and seals.
There’s visible corrosion or damage to the faucet body.
Your home has high water pressure causing multiple leaks.
You’re unsure about disassembling your faucet.

Preventing a Future Leaky or Dripping Faucet

To avoid future issues with a leaky or dripping faucet, follow these preventive measures:

Regular Maintenance: Clean and inspect faucets for signs of wear.
Avoid Over-Tightening: Turning the handle too tightly can wear out components faster.
Check Water Pressure: If you suspect high water pressure, have a professional assess it.
