With the handle removed, use an adjustable wrench to loosen and unscrew the large retaining nut that holds the cartridge in place. Turn it counter-clockwise. Once the nut is removed, use a pair of channel-lock pliers to firmly grip the stem of the white plastic cartridge and pull it straight up and out of the faucet body. Finally, insert the Allen key into the faucet body to hook and remove the small rubber washer (seat) and the spring underneath it.

Goal: Remove the old internal components of the faucet valve.

FAQs

How difficult is replacing an outdoor faucet for a beginner, and how long should I expect it to take?

This project is rated as 'beginner' difficulty, making it suitable for those new to DIY plumbing. With proper preparation and the right tools, it typically takes about 4 hours. Most of the time involves careful disconnection, preparation, and leak testing.

What are the most critical safety precautions I need to take before starting this project?

The most crucial step is to shut off the main water supply to your house and drain the lines before beginning. This prevents accidental flooding. Always wear safety glasses and gloves to protect against debris, tools slipping, or contact with old pipes.

What specific tools and materials are essential for this faucet replacement, especially for a stubborn old unit?

Beyond basic tools, you'll definitely need two sturdy pipe wrenches (like the RIDGID 31305 and TradesPro 830914) to safely remove the old faucet without twisting internal pipes. Penetrating oil (Blaster PB) is critical for seized connections, and Teflon tape along with pipe thread sealant (Hercules Real-Tuff) are essential for leak-free installation.

Why is installing a 'frost-proof' faucet recommended, and are there different types or considerations for them?

Frost-proof faucets are highly recommended because they prevent water from freezing and bursting the pipe inside your wall during cold weather, saving you from costly repairs. They come in various lengths, so measure the thickness of your exterior wall to ensure you select one that extends far enough into your house for proper function and drainage.
