Plumbing Hack: The Ultimate Guide to PEX Pipe Faucet Connections

Connecting PEX pipe to an outside faucet is a relatively simple task that can be completed with the right tools and materials. PEX pipe is a flexible, durable, and corrosion-resistant material that is ideal for outdoor plumbing applications. In this comprehensive guide, we will provide step-by-step instructions on how to connect PEX pipe to an outside faucet, ensuring a leak-proof and long-lasting connection.

Materials You’ll Need

• PEX pipe (1/2-inch or 3/4-inch diameter)
• Outside faucet
• PEX crimp tool
• PEX crimp rings
• PEX cutter
• Teflon tape
• Adjustable wrench
• Hacksaw

Step-by-Step Instructions

1. Shut Off the Water Supply

Before you begin, shut off the water supply to the outside faucet. This will prevent water from spraying out when you disconnect the old faucet.

2. Remove the Old Faucet

Use an adjustable wrench to loosen the nuts that hold the old faucet in place. Once the nuts are loose, pull the faucet straight out of the wall.

3. Clean the Threads

Use a wire brush to clean the threads on the water supply pipe. This will remove any dirt or debris that could interfere with the new connection.

4. Wrap the Threads with Teflon Tape

Apply a few wraps of Teflon tape to the threads of the water supply pipe. This will help to create a watertight seal.

5. Cut the PEX Pipe

Measure and cut the PEX pipe to the desired length. The length will vary depending on the distance between the water supply pipe and the outside faucet.

6. Insert the PEX Pipe into the Fitting

Insert the cut end of the PEX pipe into the PEX crimp fitting. Make sure that the pipe is fully inserted into the fitting.

7. Crimp the PEX Fitting

Use the PEX crimp tool to crimp the PEX crimp ring onto the fitting. The crimp ring should be crimped in two places, 180 degrees apart.

8. Connect the PEX Pipe to the Outside Faucet

Thread the PEX pipe onto the outside faucet. Hand-tighten the connection as much as possible.

9. Turn on the Water Supply

Turn on the water supply to the outside faucet and check for leaks. If there are any leaks, tighten the connection further using an adjustable wrench.

Troubleshooting Tips

• If you have difficulty inserting the PEX pipe into the fitting, try using a lubricant such as dish soap or vegetable oil.
• If the PEX crimp ring does not crimp properly, use a new crimp ring and try again.
• If you have a leak at the connection between the PEX pipe and the outside faucet, try tightening the connection further. If the leak persists, you may need to replace the PEX pipe or the outside faucet.

Quick Answers to Your FAQs

1. What size PEX pipe should I use?

For most outdoor plumbing applications, 1/2-inch or 3/4-inch diameter PEX pipe is sufficient.

2. How do I prevent the PEX pipe from freezing?

Insulate the PEX pipe with foam insulation or heat tape to prevent it from freezing in cold climates.

3. Can I use PEX pipe for both hot and cold water?

Yes, PEX pipe can be used for both hot and cold water applications.

4. How long will a PEX pipe connection last?

With proper installation and maintenance, a PEX pipe connection can last for 25 years or more.

5. What is the best way to cut PEX pipe?

Use a PEX cutter or a hacksaw to cut PEX pipe. A hacksaw will provide a cleaner cut, but a PEX cutter is faster and easier to use.

6. How do I know if a PEX crimp ring is crimped properly?

A properly crimped PEX crimp ring will have two evenly spaced indentations around the circumference of the ring.

7. What is the difference between PEX-A, PEX-B, and PEX-C?

PEX-A, PEX-B, and PEX-C are different types of PEX pipe. PEX-A is the most flexible and expensive type, while PEX-C is the least flexible and least expensive type. PEX-B is a good compromise between flexibility and cost.

8. Can I use PEX pipe for underground applications?

Yes, PEX pipe can be used for underground applications if it is properly buried and protected from damage.

9. How do I repair a leak in a PEX pipe?

Small leaks in PEX pipe can be repaired using a PEX repair clamp. Larger leaks may require replacing the damaged section of pipe.

10. How do I prevent PEX pipe from kinking?

Use a PEX bender to bend PEX pipe around corners. Avoid bending the pipe too sharply, as this can weaken the pipe.
