A dripping or leaking faucet is a common plumbing issue that wastes water, increases utility bills, and can lead to long-term damage if not addressed promptly. Fortunately, fixing a leaking faucet is often a straightforward task requiring basic tools and minimal expense.
Common Causes of Faucet Leaks
1. Worn-Out Washers or O-Rings:
• Constant use can wear down these rubber components, causing water to seep through.
2. Damaged Valve Seats:
• Corrosion or wear in the valve seat can prevent a proper seal.
3. Loose or Worn Faucet Parts:
• Screws, nuts, or other components may loosen over time, leading to leaks.
4. High Water Pressure:
• Excessive water pressure can force water through seals, causing drips.
5. Faulty Cartridges or Seals:
• In cartridge faucets, worn or damaged cartridges may allow water to leak.
6. Aging or Corrosion:
• Older faucets or those exposed to hard water may develop internal corrosion, leading to leaks.
Types of Faucets and Their Leaks
1. Compression Faucets:
• Use rubber washers to seal water flow; leaks are often caused by worn washers or O-rings.
2. Cartridge Faucets:
• Have a cartridge mechanism; leaks occur due to worn cartridges or seals.
3. Ball Faucets:
• Use a ball-and-socket design; leaks may result from worn seals or springs.
4. Ceramic Disk Faucets:
• Feature a ceramic cartridge; leaks may arise from worn seals or damaged cartridges.
Steps to Fix a Dripping or Leaking Faucet
1. Turn Off the Water Supply:
• Locate and close the shutoff valves under the sink to stop water flow.
• Open the faucet to drain any remaining water.
2. Determine the Faucet Type:
• Identify whether the faucet is compression, cartridge, ball, or ceramic disk to ensure proper repair steps.
3. Disassemble the Faucet:
• Use an adjustable wrench or screwdriver to remove the handle and expose the internal components.
• Place small parts in a secure location to avoid losing them.
4. Inspect and Replace Worn Parts:
• Washers and O-Rings:
• Check for wear or damage; replace with exact-sized components.
• Cartridge or Disk:
• Remove and inspect the cartridge or ceramic disk; replace if worn or damaged.
• Valve Seat:
• If corroded, clean with a valve seat grinder or replace entirely.
5. Reassemble the Faucet:
• Reattach all components securely, ensuring they are properly aligned.
6. Turn the Water Back On:
• Slowly open the shutoff valves and test the faucet for leaks.
• Check for smooth operation and ensure no water drips from the spout or handle.
Preventing Faucet Leaks
1. Use Moderate Water Pressure:
• Avoid setting water pressure too high to reduce strain on faucet components.
2. Perform Regular Maintenance:
• Periodically check and replace washers, O-rings, and cartridges to prevent wear.
3. Clean Faucets Regularly:
• Remove mineral buildup with vinegar or a descaling solution to maintain smooth operation.
4. Install Quality Fixtures:
• Choose durable, high-quality faucets to minimize the risk of leaks.
When to Replace the Faucet
• If the faucet is outdated or severely corroded.
• If replacement parts are no longer available or cost-prohibitive.
• To upgrade to a water-efficient or modern design.
When to Call a Professional
• If the leak persists after replacing components.
• For faucets connected to complex plumbing systems or inaccessible locations.
• To ensure proper installation of a new faucet.
Cost of Repairs or Replacement
• DIY Repairs:
• $5–$20 for washers, O-rings, or cartridges.
• $20–$50 for a faucet repair kit.
• Professional Repairs:
• $75–$200 for labor and parts, depending on the complexity.
• New Faucet Installation:
• $100–$500+ for a new faucet and installation.
