1. Worn-out O-ring

The O-ring is a small rubber ring that sits at the base of the faucet spout. It creates a seal that prevents water from leaking out. Over time, the O-ring can wear out or damage, causing leaks.

2. Loose or damaged valve seat

The valve seat is a small, circular disc inside the faucet. It is responsible for controlling the flow of water. If the valve seat is loose or damaged, it can cause water to leak out around the base of the faucet.

3. Worn-out cartridge

The cartridge is a small device that controls water flow. If the cartridge becomes worn out, it can cause leaks.

4. Improper installation

If the faucet is not installed correctly, it can cause leaks. This can happen if the faucet is not tightened properly or if the installation is not done by a professional plumber.

5. High water pressure

High water pressure can cause faucets to leak. If the water pressure is too high, it can cause the faucet to leak around the base.

6. Mineral deposits

Mineral deposits can accumulate in the faucet over time, especially in areas with hard water. These deposits can cause the faucet to leak by blocking the flow of water or by causing the valve or cartridge to become stuck. Regular cleaning with white vinegar and maintenance can help prevent mineral buildup and prolong the life of the faucet.

How to Fix a Leaky American Standard Faucet

Step 1: Turn off the Water Supply

Before beginning any repairs, turn off the water supply to the American Standard faucet. First, locate the shutoff valve under the sink or behind the wall. Turn the valve clockwise until the water supply is completely shut off. This crucial step will prevent water damage and ensure no water flows when you begin taking apart the faucet.

Step 2: Remove the Faucet Handle

Remove the handle from the faucet by lifting up the decorative cap, if there is one, and unscrewing the handle screw. Gently lift the handle off. The screw that holds the handle in place is usually located under the handle or the cap, so be sure to check both places. If the handle is stuck, use a handle puller to remove it or tap gently with a hammer to loosen it.

Step 3: Remove the Cartridge Retainer Clip

Once the handle is removed, locate the cartridge retainer clip and remove it. This clip keeps the cartridge securely in place. Most models have a U-shaped clip that sits on top of the cartridge. Gently pry it away with a flathead screwdriver or pliers, and then lift the cartridge out of the faucet body.

Step 4: Replace the O-Rings

The O-rings on the cartridge are usually the cause of leaks, so check them carefully for any cracks or damage. If they are worn or damaged, replace them with new O-rings. Before replacing them, lubricate them with silicone grease so they fit nicely in their slots.

Step 5: Reassemble the Faucet

Once the O-rings have been replaced, it’s time to put the faucet back together. Reinsert the cartridge back into the faucet body, ensuring it is properly aligned. Then, replace the cartridge retainer clip you removed in Step 3.

Step 6: Test the Faucet

After putting the faucet back together, testing it to ensure it works properly is important. Turn on the water supply and turn on the faucet. Check for leaks around the faucet and below the sink. If the faucet still leaks, double-check that you have properly replaced the O-rings or call a professional plumber.

What If the faucet still leaks after replacing the O-ring seals?

  1. Turn off the water supply to the faucet. Look for the shutoff valves under the sink and turn them clockwise until fully closed.
  2. Remove the handle from the faucet. This can usually be done by prying off the cap on top of the handle with a flathead screwdriver and then unscrewing the handle screw.
  3. Remove the retaining clip or nut that holds the cartridge in place. This will vary depending on the type of faucet you have. Some cartridges are held in place with a retaining clip, while others use a threaded retaining nut. Use pliers or an adjustable wrench to remove the clip or nut.
  4. Pull the cartridge out of the faucet body with pliers. Some cartridges may be difficult to remove and require some wiggling and to pull to loosen them from the faucet body.
  5. Take the old cartridge to a hardware store or plumbing supply store to purchase a replacement. Make sure to get a cartridge that matches the make and model of your faucet.
  6. Insert the new cartridge into the faucet body. Make sure that it is oriented correctly and fits snugly into the faucet body. Replace the retaining clip or nut to hold the cartridge in place.
  7. Reassemble the faucet by reversing the steps taken to disassemble it. Replace the handle and screw it back into place. If there is a cap on top of the handle, snap it back into place.
  8. Turn on the water supply and test the faucet for leaks. Turn the shutoff valves under the sink counterclockwise to open them and allow water to flow to the faucet. Turn on the faucet and check for any leaks around the base or handle.

Why does my American Standard faucet still leak after replacing the cartridge?

There are a number of reasons why an American Standard faucet might still leak even after replacing the cartridge. For starters, it’s possible that the cartridge was not the root cause of the issue, to begin with. Factors like water quality, faucet age, and cartridge type can all play a role in determining how well the faucet performs.

Another potential culprit is a worn seal between the valve seat and cartridge. This can cause the spout to leak and may require the purchase of American Standard faucet parts that are specifically designed to fit your particular model. By replacing the seal, you can effectively address the root cause of the problem.

It’s also possible that the faucet housing itself has sustained damage, such as a scratch or gouge, that is preventing the new cartridge from sealing properly. In this case, it may be necessary to clean out any excess material and carefully inspect the housing for any signs of damage. By doing so, you can ensure that the new cartridge is able to function properly and prevent any further leaks from occurring.

If you’ve tried all of these approaches and the faucet still continues to leak, it may be time to seek out the help of a professional plumber. With their expertise, they can help you identify and address the root cause of the problem once and for all, ensuring that your American Standard faucet is in proper working order.


In conclusion, fixing leaky American Standard kitchen faucets is a simple process. Turning off the water supply is a critical first step to prevent water damage. Removing the faucet handle, retainer clip, and cartridge allows access to the O-rings that often cause leaks, and replacing them can extend the life of your faucet.

Lubricating the O-rings ensures they work smoothly in their slots. Finally, testing the faucet confirms that the leak is fixed, providing peace of mind that the faucet will operate correctly for many years to come.
