How to Replace a Kitchen Faucet Cartridge: A DIY Guide for Courtice Homeowners

Not every plumbing issue needs a professional. Sometimes, with the right part and a little guidance, you can fix it yourself, like a leaky or stiff kitchen faucet. Often, the culprit is just a worn-out cartridge. Replacing it is easier than you think, and it can save you time, money, and a whole lot of dripping frustration.

We carry cartridges and kitchen faucet replacements from top brands like Riobel, Rohl, Kalia, Aqua Design, Rubinet, and Blanco. So if you're in Courtice and ready to tackle a quick DIY fix, this guide will walk you through it, step by step.

What You’ll Need Before You Start

Before beginning the replacement process, gather your necessary tools and materials to ensure a smooth and enjoyable experience. You'll want to have a few basic tools on hand: an adjustable wrench, both flathead and Phillips screwdrivers, an Allen key (usually provided with the faucet kit), needle-nose pliers, and a clean cloth for wiping things down. Having a cartridge puller can be helpful if the old cartridge is stubborn, but it’s not always necessary. Most importantly, you’ll need the correct replacement cartridge for your faucet model, which can be found at Plumbing & Parts Home Centre’s extensive showroom. Turning off your water supply and having a small bucket or towel handy to catch any drips will also save you from messes.

Step-by-Step: How to Replace Your Kitchen Faucet Cartridge

1.     First things first, shut off the water supply. You can use the valves under your sink or, if needed, the main shutoff. Then, turn on the faucet to release any leftover water and pressure in the line.

2.     Next, remove the handle. Most faucets have a small set screw, sometimes hidden under a decorative cap or tucked along the side. Use an Allen key or screwdriver (depending on your model) to loosen it, then carefully lift the handle off. No need to force anything, take your time.

3.     With the handle off, you’ll spot the cartridge cover or a retaining nut holding everything in place. Grab your adjustable wrench, or use your hands if it’s loose enough, and carefully unscrew it. Set it aside somewhere safe; you’ll need it when putting everything back together.

4.     Carefully pull out the old cartridge; sometimes it slides out easily, but if it’s stuck, use needle-nose pliers or a cartridge puller to coax it free gently. Take note of the cartridge’s orientation and any tabs or grooves that help it fit securely; this will be important when installing the new one.

5.     Before installing the new cartridge, use a damp cloth to clean the inside of the faucet body; any mineral buildup or debris can compromise the seal. Some brands also suggest adding a bit of silicone-based plumber’s grease to the cartridge to keep things moving smoothly and extend its lifespan.

6.     Once prepped, align the cartridge with the notches or tabs inside the faucet, and press it in firmly until it’s fully seated.

7.     Put the retaining nut or cartridge cover back on and tighten it snugly, but avoid over-tightening, as this could cause cracking.

8.     Reattach the faucet handle, secure the set screw, and reattach any decorative caps. Now turn the water supply back on and give your faucet a test run. Check for leaks and ensure everything is working smoothly. If all’s good, you’ve just handled a DIY fix like a pro!
