How to Measure a Faucet Cartridge

When dealing with leaky faucets or improper water flow, identifying and measuring the faucet cartridge is an essential first step in the repair process. The cartridge is a crucial component within the faucet that regulates water flow and temperature. Knowing how to accurately measure it ensures you can find the correct replacement part, saving time and preventing further issues.

How to Measure a Faucet Cartridge

This guide on how to measure a faucet cartridge will walk you through the process of measuring a faucet cartridge with clear, step-by-step instructions.

Why Measuring a Faucet Cartridge is Important?

Measuring a faucet cartridge is crucial for maintaining the proper functionality of your faucet. An incorrectly sized or incompatible cartridge can result in leaks, poor water pressure, and difficulty in controlling water temperature. By taking the time to measure your faucet cartridge accurately, you can avoid the frustration of purchasing the wrong replacement part.

Additionally, ensuring the correct fit extends the lifespan of your faucet, prevents unnecessary water waste, and saves money on future repairs. Accurate measurements simplify the replacement process, making it an essential step for a smooth and effective fix.

Needed Materials

  • Ruler or Caliper
  • Pen and Paper for Note-taking
  • Replacement Cartridge (Make Sure to Purchase the Correct Size and Model)
  • Adjustable Wrench or Pliers (Depending on the Type of Faucet)

8 Steps on How to Measure a Faucet Cartridge

Step 1: Turn Off the Water Supply 

Before beginning any work on your faucet, locate the water supply valves under the sink and turn them off completely.

Turn Off the Water Supply

This will prevent any water from flowing while you remove and measure the cartridge. If you cannot locate the valves or if the faucet continues to drip, shut off the main water supply to your home to ensure no interruptions occur during the process. Once the water is shut off, open the faucet to release any remaining pressure.

Step 2: Remove the Handle 

To access the faucet cartridge, you will need to remove the handle. Start by locating the screw that secures the handle in place. This is often hidden beneath a decorative cap, which can be gently pried off using a flathead screwdriver or similar tool. Once the screw is exposed, use the appropriate screwdriver or hex key to unscrew it carefully.

After the screw is removed, gently pull the handle off the faucet. If the handle is stuck, apply light pressure or wiggle it back and forth until it loosens. Be cautious not to apply excessive force to avoid damaging the components.

Step 3: Take Out Cartridge Retaining Clip 

Once the handle has been removed, you will see the cartridge secured in place by a retaining clip. Use a pair of needle-nose pliers or a flathead screwdriver to carefully remove the retaining clip.

Take care to avoid bending or damaging the clip, as it will need to be reinstalled later. Set the clip aside in a safe place to ensure it does not get lost. This step is crucial for accessing and removing the cartridge properly.

Step 4: Pull Out Cartridge 

With the retaining clip removed, you can now pull out the cartridge from the faucet assembly. Grip the cartridge firmly with your hand or use pliers if it is stuck due to sediment or mineral buildup. Gently wiggle the cartridge back and forth while pulling to loosen it.

Take care not to use excessive force, as this can damage the cartridge or the faucet body. Once the cartridge is free, inspect it for wear or buildup before proceeding to the next step.

Step 5: Inspect and Clean Cartridge 

With the cartridge removed, carefully inspect it for signs of damage, wear, or mineral deposits. Look for cracks, worn-out seals, or other defects that may affect the faucet’s performance. If the cartridge is still in good condition, proceed to clean it. 

To clean the cartridge, use a soft-bristle brush and warm, soapy water to remove any dirt or buildup. For stubborn mineral deposits, soak the cartridge in a solution of white vinegar and water for 15-30 minutes, then gently scrub the affected areas. Rinse the cartridge thoroughly with clean water and dry it with a soft cloth before reinstalling or replacing it.

Step 6: Replace Cartridge

Once the cartridge has been cleaned and dried, or if you have a new replacement cartridge ready, reinstall it into the faucet. Carefully align the cartridge with the corresponding slots or grooves in the faucet body to ensure a proper fit. Press it firmly into place, making sure it is seated evenly and securely.

After positioning the cartridge, reattach any retaining clips or screws to hold it in place. Finally, reassemble the faucet by reinstalling the handle or other components, and ensure everything is tightened properly for optimal performance.

Step 7: Reattach Handle

Once the cartridge is secured, align the handle with the faucet stem. Slide the handle onto the stem, ensuring it fits snugly and aligns correctly. Secure the handle in place by tightening the screw, if applicable, using a screwdriver or hex key.

Finally, check the handle’s movement to make sure it operates smoothly and adjusts the water flow without resistance.

Step 8: Turn Water Supply Back On 

Once everything is back in place, turn the water supply back on by turning the shut-off valve counterclockwise. Check for any leaks and make sure the faucet is functioning properly before using it again.
