No one told you about all the twists and turns you’d encounter as a homeowner. Certainly, you never gave much thought to faucet cartridges—and that’s assuming you’ve heard the term faucet cartridge before!
Yet, here we are, so here’s what you need to know.
Having reliable faucets in your home is largely dependent upon what’s called the faucet cartridge. It’s found inside the handle of the faucets located in places like your sink, tub, or shower. Most importantly is the fact that it controls things like water flow and temperature, ensuring that hot and cold water get mixed correctly.
Sounds like an important job, right?
So, while a faucet cartridge is a little-known and incredibly small component of faucets, you can understand why you’d want to learn how to maintain it, how to know when it’s time to replace it, and maybe even some DIY repair tips.
So, let’s discuss!
Maintaining Your Faucet Cartridge
Now that you know a faucet cartridge exists, let’s discuss how you can take care of it. Regular maintenance can help extend the life of your faucet cartridge. This also helps to keep your faucets working smoothly. Here are a few things homeowners can do to maintain faucet cartridges:
Cleaning: Hard water is known to leave mineral deposits on cartridges, affecting performance. Soaking the cartridge in a vinegar solution or wiping it down can help prevent buildup.
Lubrication: Silicone-based lubricants applied to moving parts can keep handles turning smoothly.
Check for Wear and Tear: Over time, rubber seals and O-rings can wear out. Regular inspections help catch problems before leaks or drips develop.
When Should You Change a Faucet Cartridge?
Regular maintenance of your faucet cartridge can help you protect it, although there’s also something to be said for its timely replacement. Look out for these common warning signs that a faucet cartridge may need to be examined by a plumber or possibly replaced:
Leaky faucets or persistent drips: Over time, cartridges can simply wear out. This is especially true of the rubber seals and O-rings. So if you notice persistent dripping, it could relate back to your faucet cartridge—but not always!
Difficulty turning the handle or adjusting temperature: Does your faucet handle feel stiff, resistant, or uneven? This could be a sign that the cartridge may be corroded or worn.
Inconsistent water pressure or temperature fluctuations: Sudden changes in the flow of your water or its temperature can point to a malfunctioning cartridge.
Strange noises or resistance when using the faucet: Grinding, squeaking, or unusual sounds can indicate the cartridge is struggling and needs attention.
Addressing these issues early may help prevent damage to valves, fixtures, or surrounding pipes. Additionally, taking the time to recognize if the problem you’re having is related to your faucet cartridge may help you save money in the long run.

Remove and Replace: Pull out the old cartridge and carefully install the new one, making sure it’s properly aligned.
Reassemble and Test: Put the handle back on, turn the water supply back on, and check that the faucet operates smoothly without leaks.
