How to Install an Outside Faucet With Pex

Installing an outside faucet with Pex might sound like a complex plumbing job, but with the right tools and a little know-how, it’s a DIY project that many homeowners can tackle. Pex tubing, known for its flexibility and durability, makes the process relatively straightforward compared to traditional copper piping. Let’s break down the steps involved in how to install an outside faucet with Pex.

You’ll Need These Tools And Materials

Before you dive into the project, it’s essential to have everything you need on hand. This will save you time and frustration later on. Here’s a checklist:

Pex tubing: The diameter should match the size of your faucet’s inlet.
Pex clamps: These secure the Pex tubing to the copper pipe.
Pex expansion tool: Used to expand the Pex tubing for a tight fit.
Outside faucet: Choose one that suits your needs and style.
Teflon tape: For sealing the faucet threads.
Pipe cutter or hacksaw: To cut the copper pipe to the desired length.
Adjustable wrenches: For tightening connections.
Sandpaper or deburring tool: To smooth the cut edges of the copper pipe.
Plumbing tape: For additional sealing, though not always necessary.
Clamps or hose clamps: For securing hoses to the faucet (if applicable).

Step One: Shutting Off the Water Supply

The very first step in learning how to install an outside faucet with pex involves safety. Before you start tinkering with your plumbing, it’s crucial to turn off the water supply. Locate the shut-off valve for the water line you’ll be working on. Typically, it’s a handle or wheel that you turn clockwise to close. If you’re unsure about the location, consult your home’s plumbing diagram or call a plumber.

Step Two: Prepare the Copper Pipe

The next step involves getting the copper pipe ready for the Pex tubing. You’ll need to cut it to the desired length. A pipe cutter is ideal for clean cuts, but a hacksaw can also work. Once cut, it’s essential to deburr the pipe’s edges. Burrs can cause leaks or damage the Pex tubing. Use sandpaper or a deburring tool to smooth out any rough spots.

Step Three: Insert and Expand the Pex Tubing

Now comes the heart of the project. Slide a Pex clamp onto the tubing before inserting it into the copper pipe. Push the tubing in as far as it will go to ensure a snug fit. Then, comes the expansion process. This is where the Pex expansion tool comes in. Slide the tool over the Pex tubing and the clamp, and according to the tool’s instructions, expand the tubing.

Once expanded, slide the clamp up to the expanded section and tighten securely. This creates a tight seal.

Step Four: Install the Outside Faucet

With the Pex tubing securely in place, it’s time to attach the faucet. Wrap Teflon tape around the faucet threads in a clockwise direction to create a watertight seal. Screw the faucet onto the Pex tubing, using adjustable wrenches to tighten it without overdoing it. Overtightening can damage the faucet or the Pex connection.

Step Five: Reconnect the Water Supply and Test

Slowly turn on the water supply and check for leaks. Tighten any connections that seem loose. Once you’re confident there are no leaks, fully open the faucet and let it run for a few minutes. Keep an eye out for any drips or signs of water escaping.

Must Consider These Factors!

Planning: If you’re installing multiple faucets, plan the layout of the Pex tubing to avoid unnecessary bends and twists.
Frost protection: Consider using frost-proof outside faucets in colder climates to prevent freezing and damage.
Safety first: Always prioritize safety. Wear gloves to protect your hands, and be cautious when working with sharp tools.

Troubleshooting Common Issues with Your New Outside Faucet

While installing an outside faucet with Pex is generally a straightforward process, you might encounter some hiccups. Let’s tackle some common problems and their solutions.

Leaks: The Unwanted Guest

Leaks are the most common issue after installing a new faucet. Here are some potential culprits:

Loose connections: Double-check that all connections, especially the Pex clamps and the faucet itself, are tightened securely. A small leak can quickly turn into a big problem.
Damaged Pex tubing: If the Pex tubing was cut improperly or has been damaged during installation, it might be leaking. Inspect the tubing for any cuts or kinks.
Faulty faucet: In rare cases, the faucet itself might be defective. If you’ve checked all connections and the tubing is intact, the faucet might be the issue.

Frozen Faucets: A Winter Woe

Living in a colder climate means dealing with the threat of frozen pipes. Here’s how to protect your outside faucet:

Insulation: Wrap the faucet with insulation materials like pipe wrap or foam sleeves to prevent freezing.
Drainage: Before the first frost, turn off the water supply to the faucet and open it to drain any remaining water.
Frost-proof faucet: Consider investing in a frost-proof faucet, which has a longer internal pipe that extends below the frost line.

Low Water Pressure: A Frustrating Flow

If you’re experiencing low water pressure from your new faucet, here are some possible causes:

Clogged aerator: The aerator at the faucet’s end can become clogged with mineral deposits. Unscrew it and clean it out.
Partially closed shut-off valve: Make sure the shut-off valve is fully open.
Restrictions in the water supply line: Check for any kinks or obstructions in the Pex tubing or the copper pipe.

Difficulty Expanding Pex Tubing

If you’re struggling to expand the Pex tubing, here are some tips:

Correct tool: Ensure you’re using the right expansion tool for the size of your Pex tubing.
Proper technique: Follow the manufacturer’s instructions for the expansion tool.
Tubing quality: Low-quality Pex tubing might be more difficult to expand. Consider using a reputable brand.

By understanding these common issues and their solutions, you can troubleshoot problems effectively and enjoy your new outside faucet without hassle.

How to Maintain Your Outside Faucet

To keep your outside faucet working smoothly for years to come, follow these maintenance tips:

Regular inspection: Check for leaks, corrosion, or damage during the warmer months.

Winterization: In colder climates, follow the winterization steps mentioned earlier.

Lubrication: Occasionally apply a small amount of lubricant to the faucet handles for smooth operation.

Cleaning: Clean the faucet with mild soap and water to remove dirt and grime.

With proper care and maintenance, your outside faucet will provide reliable service for many seasons.
