How to Fix a Leaky Faucet

If you’re dealing with a pesky, persistent leaky faucet, knowing “How to Fix a Leaky Faucet” can save you both money and frustration. Fixing a leaky faucet is a common household repair that doesn’t require advanced plumbing skills. Usually, the issue is caused by a worn-out washer or O-ring, which can be easily replaced. In this guide, we’ll walk you through the basic steps to troubleshoot and repair your leaky faucet, helping you regain control over your water bill and enjoy a peaceful night’s sleep without the constant drip, drip, drip.

Identifying the Type of Kitchen Faucet

The initial action in rectifying a dripping faucet involves determining your faucet type. There are three primary types of single lever faucets you may encounter in your kitchen: rotary ball, cartridge-style, and ceramic disc faucets.

Rotary ball faucets, or ball faucets, are characterized by a single handle mounted atop a rounded cap on the spout. Cartridge-style faucets, on the other hand, feature two handles for hot and cold water, each equipped with a faucet cartridge valve. Ceramic disc faucets are a modern alternative to cartridge faucets, operated by a single lever that controls the water flow through ceramic discs inside the cartridge. Among these types, the ceramic disk faucet stands out for its durability and efficiency, thanks in part to its valve body design.

To identify your faucet type, examine the handle and spout design. Here are some key indicators:

  1. Single handle on a rounded cap: rotary ball faucet
  2. Two separate handles for hot and cold water: cartridge-style faucet
  3. Single lever controlling water flow: ceramic disc faucet

Essential Tools and Materials

Tools and materials needed to repair a kitchen faucet, such as an Allen wrench, o-rings, and a replacement retainer ring

Before embarking on the repair journey, amassing all required tools and materials becomes paramount for a seamless and victorious project. For most faucet repairs, you’ll need:

  • an adjustable wrench
  • a crescent wrench
  • a flathead screwdriver
  • slip-joint pliers with duct tape-covered jaws (for removing a leaky cartridge faucet)

When it comes to replacement parts, you have a choice between purchasing individual seals and washers or opting for a faucet repair kit from your local hardware store. For ceramic disc faucets, you may need to acquire a replacement disc cartridge if the existing one is damaged.

White vinegar can be used to remove mineral deposits from faucet parts. A soft scouring pad is also helpful in making the task easier and faster. With all your tools and materials at hand, you’re now ready to tackle that pesky faucet leak.

Locating the Leak Source

Prior to initiating any repairs, it is imperative to disconnect the water supply to the problematic faucet, either by turning off the hot and cold fixture shutoff valves or closing the main water supply if the individual valves are stuck. To prevent small parts from falling into the drain during the repair process, place strainer baskets or rags over the sink drain holes.

To locate the source of the faucet leak, follow these steps:

  1. Inspect the faucet handle to see if it is loose or damaged.
  2. Check the valve seat for any signs of wear or corrosion.
  3. Examine the spout for any cracks or leaks.
  4. Sequentially shut off the water supply valves to determine if the leak stops.

Once you’ve identified the source of the leak, you can proceed with the appropriate repair steps based on your faucet type.

Fixing Rotary Ball Faucet Leaks

Suppose you’re dealing with a rotary ball faucet, begin by taking off the handle, cap, and rotary ball. Next, replace the seat washer, which is responsible for rectifying the leaky faucet. Before installing the new washer, coat it with plumber’s grease to ensure smooth operation.

After replacing the seat washer, reassemble the faucet, ensuring all components are securely in place. Test the faucet to ensure the leak has been resolved. If the leak persists, you may need to inspect other parts of the faucet for damage or wear.

Repairing Cartridge-Style Faucet Leaks

In case of cartridge-style faucets, initiate the process by taking out the Allen screw and metal handle adapter with the aid of a spanner cap and slip-joint pliers. If the cartridge is difficult to remove, you may need to use a cartridge-pulling tool for additional force.

Once the cartridge is removed, follow these steps to clean and inspect it.

  1. Clean any mineral buildup using distilled white vinegar and a scouring pad or rag.
  2. Inspect the cartridge for damage.
  3. Replace the O-rings or the entire cartridge if necessary.

When reassembling the faucet, ensure the cartridge is inverted and the rubber seals are properly installed. Test the faucet to confirm the leak is resolved.

  2. Inspect the cartridge for damage, such as cracked discs or worn rubber seals.
  3. If the seals are the issue, replace them.

After replacing the O-rings, reassemble the faucet, making sure all components are securely in place. Test the faucet to confirm the leak is resolved.

Cleaning and Maintenance Tips

For warding off future leaks and extending your faucet’s lifespan, ensure routine cleaning and maintenance of your faucet components. Here are some steps to follow.

  1. Use vinegar to remove mineral deposits that may cause leaks or damage to the faucet parts.
  2. Regularly inspect your faucet components for any signs of wear or damage.
  3. Replace any worn or damaged components as needed.

By following these steps to fix a leaky faucet, you can keep your faucet in good condition and prevent leaks.

When completing repairs on an older ceramic disc faucet, it’s advised to leave the faucet open as water is turned back on, allowing any trapped air in the lines to be released. Proper cleaning and maintenance can save you time, money, and frustration in the long run.

Common Faucet Leak Troubleshooting

Even with your utmost diligence, you might run into some hurdles while trying to fix faucet leaks. If your faucet continues to drip water only during certain times or when the handles are moved in a particular manner, the home’s water pressure could be the source of the problem. Adjusting the water pressure may resolve the issue.

If the water flow through the faucet is slow, unscrew the aerator and clean it out to improve water flow. Additionally, if any components of your faucet are aged or impaired, it’s recommended to replace them to prevent future leaks.

Lastly, removing mineral deposits from faucet parts can be achieved by soaking them in vinegar. Regular cleaning and maintenance will help prevent future leaks and keep your faucet in top condition.

When to Call a Professional Plumber

Though numerous leaking faucet issues can be handled with a bit of DIY expertise, certain situations warrant the intervention of a professional plumber. If the leak persists despite your best efforts, or if the faucet requires extensive repairs, don’t hesitate to seek professional help. A skilled plumber can quickly diagnose and resolve the issue, saving you time and frustration.

Additionally, if you’re unsure of the location of your water main, it’s advisable to enlist the services of a professional plumber to help you identify and shut off the water supply before attempting any repairs.
