Water Still Dripping After Shut Off Valve Key Takeaways

  • Dripping water after shutting off the valve can waste water and money.
  • Common causes of a dripping faucet include a damaged cartridge, broken washers, water pressure issues, a malfunctioning O-ring, or a deteriorated valve seat.
  • You can fix a leaky faucet yourself by following step-by-step instructions.
  • Knowing the different types of faucets will help you understand how to disassemble and repair them if needed.
  • If you’re unable to fix the issue yourself, it’s best to seek professional faucet and plumbing installation services.

Causes of Leaky Faucets

Leaky faucets can be frustrating, wasteful, and expensive. Understanding the causes of leaky faucets is essential to effectively fix them. Here are the main five causes:

  1. A Damaged Cartridge
  2. Broken Washers
  3. Water Pressure
  4. Malfunctioning O-Ring
  5. Deteriorated Valve Seat

Let’s explore each cause in more detail.

A Damaged Cartridge

A damaged cartridge is a common cause of leaks in cartridge-style faucets. The cartridge controls the flow of water, and when it becomes damaged, it can lead to dripping or constant flow. Replacing the cartridge is usually the solution to fix this issue.

Broken Washers

Washers are found in compression-style faucets and can wear out over time. When washers become worn or damaged, they can cause leaks. Replacing the washer can usually resolve the problem and stop the faucet from dripping.

Water Pressure

High water pressure can put excessive strain on your faucet, leading to leaks. If your faucet is constantly dripping even after replacing the cartridge or washer, water pressure may be the culprit. Consider installing a pressure regulator to reduce the water pressure and prevent further leaks.

Malfunctioning O-Ring

An O-ring is a small rubber ring found in cartridge-style faucets that helps create a watertight seal. When the O-ring becomes worn or damaged, it can cause leaks. Replacing the O-ring is usually the solution to fix this type of leak.

Deteriorated Valve Seat

The valve seat is the connection point between the faucet and the spout. Over time, the valve seat can deteriorate due to corrosion, leading to leaks. Contacting a professional plumber to inspect and replace the corroded valve seat is recommended to properly fix this issue.

By understanding the causes of leaky faucets, you can diagnose the problem and take the necessary steps to fix it. Whether it’s replacing a damaged cartridge, washer, or O-ring, or addressing high water pressure or a deteriorated valve seat, resolving leaky faucets will help you save water, money, and prevent further damage.

How to Fix a Leaky Faucet

If you notice that your faucet is leaking, don’t worry – you can tackle the problem yourself and save money on repairs. By following these simple steps, you’ll be able to fix a leaky faucet in no time.

Step 1: Deactivate the Water

The first step in fixing a leaky faucet is to deactivate the water supply. Locate the fixture shutoff valves below the sink and turn the handles clockwise to shut off the water. If your faucet doesn’t have shutoff valves, turn off the main water supply for the house.

Step 2: Disassemble the Faucet Handles

To access the inner components of the faucet, you’ll need to disassemble the handles. Depending on the type of faucet, you may need to use a hex key or Allen wrench to remove the handle, or pry off the top screw cover and loosen the screw underneath.

Step 3: Inspect and Replace Damaged Parts

Once you have removed the handle, inspect the various parts of the faucet for any signs of damage or wear. Common culprits include worn-out washers or O-rings, a corroded valve seat, or a faulty cartridge. Replace any damaged parts with new ones to ensure a proper seal.

Step 4: Sanitize and Reassemble

After replacing the damaged parts, it’s important to sanitize the valves and clean any debris or buildup. This will help prevent future leaks and ensure the smooth operation of your faucet. Once the valves are clean, reassemble the faucet handles, turn the water line back on, and run both hot and cold water to check for any leaks.

By following these steps and understanding the common causes of faucet leaks, you’ll be able to fix a leaky faucet on your own. However, if you’re unable to resolve the issue or if you need assistance with any other plumbing problems, it’s always best to contact a professional plumber for help.

Types of Faucets

When it comes to faucets, there are four common types that you should be familiar with. Understanding the different types of faucets can help you with disassembly and repairs if needed. Here are the four types:

  1. Cartridge Faucets: These faucets use a cartridge to control the flow of water. They are known for their smooth and easy operation.
  2. Disc Faucets: Disc faucets have two ceramic discs that control the flow of water. They are highly durable and offer precise temperature and volume control.
  3. Ball Faucets: Ball faucets have a single handle that controls both the temperature and the flow of water. The handle sits on top of a ball-shaped cap, which is responsible for regulating the water.
  4. Compression Washer Faucets: These traditional faucets have separate hot and cold handles, which are turned to control the temperature. They feature washers that create a seal when the handles are tightened.

Each type of faucet has its own unique design and mechanism, so it’s important to identify the type of faucet you have before attempting any repairs. This will ensure that you have the right tools and knowledge to fix the issue properly.

Shut Off the Water

The first step in fixing a dripping faucet is to shut off the water supply. This will prevent any further water from flowing into the faucet and allow you to work on it without any risk of flooding or water damage. To shut off the water, follow these steps:

  1. Locate the fixture shutoff valves: Look for the shutoff valves below the sink. These are usually small valves connected to the water pipes leading to the faucet.
  2. Turn off the valves: Using a clockwise motion, turn the handles of the shutoff valves. This will close the valves and stop the flow of water to the faucet.

If your faucet doesn’t have any shutoff valves, you will need to turn off the main water supply for the house. This is usually located near the water meter or in the basement. Turn the main valve clockwise to shut off the water supply to your entire home.

By shutting off the water supply, you can safely proceed with the next steps of fixing your dripping faucet.

Remove the Handle

Before you can fix your leaky faucet, you’ll need to remove the handle. The method for removing the handle will depend on the type of faucet you have. For faucets with a hex key or Allen wrench, you’ll need to locate the set screw on the handle and use the appropriate tool to loosen and remove it. If your faucet has a top screw cover, pry it off gently to reveal the screw underneath. Loosen and remove this screw to detach the handle. Be sure to keep track of any small parts or screws as you remove the handle.

If you’re unsure about how to remove the handle or encounter any difficulties, consult the manufacturer’s instructions or consider reaching out to a professional plumber for assistance.

Types of Faucet Handles

There are several types of faucet handles, and each requires a different removal method. Here are the most common types:

  • Hex key or Allen wrench: Look for a set screw on the handle, usually located on the underside or the back. Loosen and remove the screw to detach the handle.
  • Top screw cover: Some handles have a decorative top cover that conceals the screw underneath. Carefully pry off the cover to access the screw and remove it.
  • Knob-style: Knob handles typically have a base that screws on or off. Hold the base firmly and twist counterclockwise to remove it.
  • Lever handle: Lever handles often have a small setscrew on the side or back. Loosen and remove the screw, then slide the handle off the stem.

Remember to exercise caution when removing the handle to avoid causing any damage to the faucet or injuring yourself. Take your time and follow the appropriate steps for your specific faucet type.

Handle TypeRemoval Method
Hex key or Allen wrenchLoosen and remove the set screw on the handle
Top screw coverPry off the cover to access and remove the screw
Knob-styleHold the base and twist counterclockwise to remove
Lever handleLoosen and remove the setscrew, then slide off the handle

Once you have successfully removed the handle, you can proceed with the next steps to fix your leaky faucet.

Remove the Cartridge or Stem

If you’ve followed the previous steps and still have a dripping faucet, it’s time to remove the faulty cartridge or stem. This is a crucial step in the repair process, as the cartridge or stem is responsible for controlling the flow of water.

To remove the cartridge or stem, begin by locating the packing nut, which secures the part in place. Use a wrench to loosen the packing nut, turning it counterclockwise. Be careful not to apply too much force, as you don’t want to damage the surrounding components.

Once the packing nut is loosened, gently pull the cartridge or stem out of the assembly. You may need to wiggle it back and forth to release it completely. Take note of its orientation and position, as this will be important when installing the new cartridge or stem later on.

Inspect for Damage

While you have the cartridge or stem removed, take a moment to inspect it for any signs of damage or wear. Look for cracks, chips, or deterioration in the plastic or rubber components. If you notice any issues, it’s best to replace the cartridge or stem entirely with a new one to ensure a proper fix.

However, if the cartridge or stem appears to be in good condition, you can proceed with cleaning it thoroughly. Use a soft brush or cloth to remove any debris or buildup that may be causing the leak. This will help to improve the performance and longevity of the cartridge or stem.

Common Issues with Cartridges and StemsPossible Solutions

By removing the faulty cartridge or stem, you’re one step closer to fixing your leaky faucet. Once you’ve completed this step, you can proceed with installing the new cartridge or stem, as outlined in the next section.

Install New Cartridge

Once you have identified the type of cartridge or stem you need for your faucet, it’s time to install the new one. But before you begin, make sure to clean the area around the handle and parts to ensure a proper fit.

Begin by inserting the new cartridge or stem into the faucet assembly. Take care to align it correctly so that it fits snugly. You may need to use a wrench to tighten the packing nut gently, ensuring that the cartridge is securely in place.

Once the new cartridge is installed, it’s time to reassemble the faucet. Follow the steps in reverse order, ensuring that each component is properly aligned and attached. Take your time to ensure a tight fit to prevent any future leaks.

Once the faucet is reassembled, it’s time to turn the water line back on and check for any leaks. Run both hot and cold water to ensure everything is functioning properly. If you notice any leaks, double-check the cartridge installation and make any necessary adjustments.

By following these steps, you can successfully install a new cartridge in your faucet and eliminate those stubborn leaks. Remember, if you’re unsure or uncomfortable with the installation process, it’s always best to contact a professional plumber for assistance.

Reattach Faucet Handle

After installing the new cartridge or stem in your leaking faucet, it’s time to reattach the faucet handle. This step will ensure that your faucet is properly secured and functioning correctly. Here’s a simple guide on how to reattach the faucet handle:

  1. Locate the opening on top of the faucet handle.
  2. Align the opening with the valve stem.
  3. Slide the faucet handle back onto the valve stem.
  4. Make sure the handle is securely in place and aligned properly.
  5. If necessary, tighten any screws or fasteners that hold the handle in place.
  6. Once the handle is reattached, turn the water line back on.
  7. Run both hot and cold water to check for any leaks.

By following these steps, you can successfully reattach the faucet handle and complete the repair process. Remember to double-check for any leaks after turning the water back on. If you notice any leaks or continue to experience dripping water, it may be necessary to seek professional assistance from a plumber.

Remember, a properly functioning faucet can save you money and prevent unnecessary water waste. Taking the time to fix a leaking faucet can have a positive impact on both your wallet and the environment.

Cause #1: A Worn-out Washer or O-ring

One of the most common causes of a leaky faucet is a worn-out washer or O-ring. These small components can deteriorate over time due to regular use and can cause water to seep through the faucet. Compression-style faucets typically have washers, while cartridge-style faucets are equipped with O-rings.

To fix this issue, you will need to disassemble the faucet and replace the worn-out washer or O-ring. It is important to note that different faucets may require different types of washers or O-rings, so make sure to identify the correct replacement parts before proceeding.

Here is a step-by-step guide to fixing a leaky faucet caused by a worn-out washer or O-ring:

  1. Turn off the water supply by shutting off the fixture shutoff valves located below the sink, or by turning off the main water supply for the house if there are no shutoff valves.
  2. Remove the faucet handle using the appropriate tool, such as a hex key or Allen wrench.
  3. Locate the washer or O-ring inside the faucet assembly and carefully remove it.
  4. Take the old washer or O-ring to a hardware store to find an exact replacement.
  5. Clean the area around the handle and parts before installing the new washer or O-ring.
  6. Insert the new washer or O-ring, ensuring it is properly aligned.
  7. Reattach the faucet handle and turn on the water supply to check for any leaks.

By replacing the worn-out washer or O-ring, you can effectively fix a leaky faucet and prevent further water wastage. However, if you are unsure about the type of faucet or have difficulty with the repair process, it is recommended to seek the assistance of a professional plumber.

Cause #2: A Corroded Valve Seat

A corroded valve seat is another common cause of a leaking faucet. Over time, the constant exposure to water can cause corrosion to build up on the valve seat, leading to leaks. This problem is often seen in older faucets or those with hard water deposits. When the valve seat becomes corroded, it no longer forms a tight seal with the washer, allowing water to flow through and drip from the faucet.

To fix a corroded valve seat, it is recommended to contact a plumber. They have the expertise and tools to inspect the extent of the corrosion and replace the valve seat if necessary. Attempting to repair or replace the valve seat yourself may cause further damage to the faucet, resulting in more extensive repairs.

By addressing the issue of a corroded valve seat promptly, you can prevent further water wastage and potential damage to your faucet. A professional plumber will ensure that the new valve seat is installed properly, restoring your faucet’s functionality and preventing any future leaks.

Cause #3: A Faulty Cartridge

Another common cause of a leaky faucet is a faulty cartridge. Some bathtub faucets use cartridges to control the flow of water. Over time, these cartridges can degrade and develop leaks, resulting in dripping water even when the faucet is turned off. If you suspect that a faulty cartridge is the cause of your leaky faucet, it’s best to contact a professional plumber to replace or repair it.

A faulty cartridge can be a complex issue to fix, especially if you’re not familiar with faucet repair. A plumber will have the necessary expertise and tools to identify the specific problem with the cartridge and provide an appropriate solution. They may need to disassemble the faucet, remove the old cartridge, and install a new one. By relying on a professional, you can ensure that the faulty cartridge is effectively addressed, and your faucet functions properly once again.

Remember, attempting to fix a faulty cartridge on your own without the necessary knowledge and experience can lead to further damage or even exacerbate the leak. It’s always better to entrust the repair to a qualified professional to avoid any complications and ensure a successful resolution.
