How to Tell if a Faucet Cartridge is Bad

A faulty faucet cartridge can cause a variety of issues, from drips and leaks to problems with water pressure and temperature control. Identifying whether the cartridge is the source of your faucet troubles is crucial for maintaining your plumbing system and avoiding more significant water damage.

How to Tell if a Faucet Cartridge is Bad

By understanding the signs of a bad faucet cartridge, you can quickly address the problem and ensure your faucet operates smoothly and efficiently. In this blogpost on how to tell if a faucet cartridge is bad, we’ll discuss the common symptoms of a faulty faucet cartridge and how to troubleshoot them.

What is a Faucet Cartridge?

Before we dive into identifying a bad faucet cartridge, let’s first understand what it is and how it works. A faucet cartridge is a small cylinder-shaped valve that controls the flow of water in your faucet. It sits inside the handle and connects to the spout, allowing you to turn on or off water and adjust temperature and pressure.

There are two types of faucet cartridges: compression cartridges and ceramic disk cartridges. Compression cartridges use rubber washers to seal the water flow, while ceramic disk cartridges use ceramic plates to control the flow. Both types can malfunction, leading to issues with your faucet.

Common Signs of a Bad Faucet Cartridge

Dripping or Leaking Faucet

One of the most common signs of a bad faucet cartridge is a dripping or leaking faucet. If you notice water continuing to drip from the spout even after the faucet has been turned off, the cartridge could be worn out or damaged. This issue typically arises because the seals inside the cartridge are no longer effectively containing the water flow, leading to continuous leakage. Dripping faucets not only wastes water but can also lead to higher utility bills and potential water damage over time. To address this problem, you may need to replace the faulty cartridge to restore proper function and prevent further leaks.

Most Common Signs of a Bad Faucet Cartridge

Low Water Pressure

Another sign of a bad faucet cartridge is low water pressure. If you turn on your faucet and notice that the water is only trickling out, it could be due to a faulty cartridge. Over time, buildup such as mineral deposits, can clog the small openings in the cartridge, limiting the flow of water. Cleaning or replacing the cartridge should restore proper water pressure.

Inconsistent Water Temperature

If your faucet’s hot and cold water mix is inconsistent, this could also indicate a problem with the faucet cartridge. A malfunctioning cartridge may not be able to properly regulate the temperature of the water flowing through it, causing fluctuations from hot to cold. This issue can be frustrating when trying to find just the right temperature for washing dishes or taking a shower. Replacing the faulty cartridge can help restore consistent water temperature control.

11 Step-by-step Guides on How to Tell if a Faucet Cartridge is Bad

Step 1: Turn Off the Water Supply

First, you’ll need to turn off the water supply to your faucet by closing the shut-off valves under the sink. This will prevent any water from flowing while you work on the cartridge. The shut-off valves are typically located on the pipes leading to the faucet. You may need to use pliers to turn them. It’s also a good idea to close the drain stopper in your sink to prevent any small parts from falling down the drain.

Step 2: Remove the Faucet Handle

Next, you’ll need to remove the faucet handle. This can usually be done by unscrewing a small screw at the base of the handle with a screwdriver or an Allen wrench. You may also need to use a handle puller if the handle is stuck. Although it may vary depending on the faucet model, most handles can be removed by lifting them straight up.

Step 3: Remove the Cartridge Retaining Clip

Once you’ve removed the handle, you’ll see a cartridge retaining clip or nut holding the cartridge in place. Use pliers to remove this clip or nut and set it aside. It’s crucial to remember the order of any parts you remove so that you can reassemble them correctly later. You may also need to use a cartridge puller if the cartridge is stuck in place.

Step 4: Pull Out the Cartridge

With the retaining clip or nut removed, gently pull out the cartridge from its housing using pliers. If it’s difficult to remove, you may need to use a cartridge puller tool specifically designed for this purpose. Be careful not to damage any other parts of your faucet during this step. It’s also helpful to take a photo of the cartridge before removing it so that you can compare it to the new one when replacing it.

Step 5: Inspect the Cartridge

Once you’ve removed the cartridge, inspect it for any signs of wear or damage. Look for cracks, tears, or mineral buildup that may be affecting its function. If you notice any issues, it’s a clear indicator that the cartridge needs to be replaced. There may also be a model number or brand name on the cartridge, which can help you find a suitable replacement.

Step 6: Check for Proper Water Flow

While the cartridge is out, turn on the water supply and see if water flows freely through the housing where the cartridge sits. If there are any obstructions or clogs in this area, it could also affect your faucet’s performance and indicate a faulty cartridge. You can use a small brush or toothbrush to clean any buildup in this area before reassembling.

Step 7: Replace with New Cartridge

If your inspection reveals that the cartridge is indeed faulty, it’s time to replace it with a new one. Make sure to purchase the correct type of cartridge for your faucet model and follow the manufacturer’s instructions for proper installation. It’s always a good idea to read the instructions beforehand, as some cartridges may require specific steps for replacement.

Step 8: Reassemble the Faucet

Once you’ve installed the new cartridge, carefully reassemble the faucet in reverse order. Remember to put back any retaining clips or nuts and secure them tightly. Double-check that all parts are in their correct positions before turning on the water supply again. But before doing so, it’s also a good idea to flush out the faucet by running water for a few minutes to remove any debris or air from the lines.

Step 9: Test for Leaks

With everything reassembled, turn on the water supply and test your faucet for any leaks. If there are no longer drips or leaks from the spout, then your problem has been solved! However, if you still notice leaks, it may indicate another issue with your faucet that will need to be addressed. The best course of action in this case would be to contact a professional plumber for further assistance. It’s always better to be safe than sorry.

Step 10: Clean and Maintain

To prevent future issues with your faucet cartridge, make sure to regularly clean and maintain it. This includes removing any buildup or debris from the cartridge and its housing. You can also use vinegar or a specialized cleaner to remove mineral deposits. You can also opt to install a water softener if you have hard water, which can prevent mineral buildup in your faucet and other plumbing fixtures.

Step 11: Seek Professional Help

If you are unsure about how to proceed or if you encounter any complications during the process, it’s best to seek professional help from a plumber. They have the knowledge and tools necessary to safely and effectively replace your faucet cartridge. It may cost a bit more, but it’s better than causing further damage to your faucet or creating a bigger problem for yourself. Plus, you’ll have peace of mind knowing that the job has been done correctly. 

Following these 11 steps on how to tell if a faucet cartridge is bad can help you determine if your faucet cartridge is the source of any issues with your faucet and guide you through the process of replacing it.
