Why Faucets Drip: Common Causes
Before attempting any leaky faucet repair, it’s important to understand what’s causing the problem. Most drips are linked to worn-out or damaged internal parts, such as:
- Worn washers or seals – Over time, rubber washers harden, crack, or lose their shape.
- Loose or damaged O-rings – These create a seal in the handle and spout but can wear out from constant use.
- Corroded valve seats – Mineral buildup or corrosion prevents a tight seal, allowing water to drip.
- Faulty cartridges – Found in modern faucets, a failing cartridge often results in steady dripping.
By identifying the cause, you’ll save time and know exactly what needs replacing.
Types of Faucets and How to Fix Them
Not all faucets are built the same. Knowing your faucet type will determine the right repair approach. The four main designs include:
1. Compression Faucets
- Common in older homes, featuring separate hot and cold handles.
- Drips usually result from worn seat washers.
How to fix: Replace the rubber washer and O-ring, and apply plumber’s grease for smoother operation.
2. Cartridge Faucets
- Easy to identify by their single handle and smooth operation.
- A bad cartridge or O-ring often causes the drip.
How to fix: Remove the handle, pull out the old cartridge, and replace it with a matching part.
3. Ceramic Disk Faucets
- Known for durability and found in newer kitchens.
- Drips often occur due to worn neoprene seals.
How to fix: Replace the seals, clean mineral deposits with vinegar, and reassemble carefully.
4. Ball-Type Faucets
- Found in many kitchens, containing multiple parts.
- Leaks can come from springs, seats, or worn internal components.
How to fix: Use a faucet repair kit to replace springs, seats, and worn seals in one go.

Steps to Prepare Before Repair
To make your fix leaky faucet project easier, prepare your workspace properly:
- Shut off the water supply under the sink.
- Plug the drain to prevent small parts from falling in.
- Gather tools – screwdriver, wrench, pliers, and plumber’s grease.
- Lay out parts in order as you disassemble.
- Buy replacement parts (washers, cartridges, or O-rings) before starting.
Good preparation saves time and ensures you don’t damage the faucet further.
Tips for a Successful Faucet Repair
- Apply plumber’s grease to all moving parts for longevity.
- Avoid overtightening screws or nuts, which can cause cracks.
- Clean components thoroughly before reinstalling.
- Test the faucet by slowly turning the water back on to check for leaks.
- If drips continue, the seat or valve may be corroded and require replacement.
When to Call a Professional
While many homeowners can fix a leaky faucet on their own, some situations require expert help:
- You can’t identify the cause of the drip.
- The faucet body is cracked or badly corroded.
- Repairs fail to stop the leak.
- Complex faucets (like ball-type) feel overwhelming.
A licensed plumber will ensure the repair is done quickly and safely—and can recommend upgrades if your faucet is outdated.
