Mastering PEX Plumbing


Welcome to Dovis Plumbing, where we're excited to dive into the world of PEX piping! PEX, or cross-linked polyethylene, has revolutionized the plumbing industry with its flexibility, affordability, and ease of installation. In this comprehensive guide, we'll cover everything you need to know about your homes PEX plumbing in Cooper City, from its advantage over traditional materials to installation tips and tricks. Let's get started!

What is PEX Piping?

PEX piping is a flexible plastic tubing used for residential and commercial plumbing applications. Unlike rigid materials like copper or PVC, PEX can bend and flex, making it ideal for tight spaces and complex installations. Its affordability and ease of installation have made it a popular choice for plumbing professionals and DIY enthusiasts alike.

Advantages of PEX Over Copper

PEX piping offers several advantages over traditional copper pipes:

Cost: PEX is significantly cheaper than copper, making it a cost-effective option for plumbing projects.

Installation: PEX installs much faster than copper, thanks to its flexibility and ease of use. Whether you're running a main line or connecting fixtures, PEX fittings are quicker to install than soldering copper.

Corrosion Resistance: Unlike copper, PEX is resistant to corrosion, making it an excellent choice for areas with acidic water.

PEX vs. CPVC: Making the Right Choice

While both PEX and CPVC are viable options for plumbing, PEX offers several advantages:

Ease of Installation: PEX requires no glue, making installation cleaner and easier.

Freeze Resistance: PEX is less likely to burst if it freezes compared to CPVC.

Flexibility: PEX is more flexible and available in longer lengths, making it easier to fish through walls during remodeling projects.

Special Tools for PEX Plumbing

When working with PEX piping, you'll need a few special tools:

Crimp Rings: Used to secure fittings to PEX tubing, crimp rings require a crimp ring tool for installation.

Cinch Clamps: Similar to crimp rings, cinch clamps are another option for securing fittings and require a cinch clamp tool.

Tubing Cutter: A scissors-like cutter is used to cut PEX tubing to length.

Connecting PEX to Existing Plumbing

Connecting PEX fittings to existing plumbing is straightforward:

Stab-In Tee: Cut out a section of plumbing pipe and insert a stab-in tee for a quick and easy connection.

Soldered Tee: Solder in a tee and a PEX supply adapter, then connect the PEX tubing using your chosen method.

Using Manifolds with PEX

While not required, manifolds offer several advantages for PEX plumbing:

Simplified Installation: Manifolds streamline plumbing runs and reduce potential leaks by eliminating the need for multiple fittings.

Faster Installation: With a manifold system, you can run a separate PEX tube to each fixture, making installation quick and efficient.

Meeting Code Requirements

Before starting your PEX plumbing project, be sure to check local code requirements with your plumbing inspector.

Color Coding and Tubing Grades

PEX tubing is available in red and blue colors to distinguish hot and cold lines. Additionally, there are three grades of PEX tubing: PEX-A, PEX-B, and PEX-C, with PEX-A being slightly more flexible.

Reliability of PEX

PEX piping has a proven track record of reliability, with thousands of leak-free installations worldwide. Most issues with PEX systems are due to installation errors rather than the tubing itself.

Handling Freezing Conditions

While PEX is less likely to burst than rigid piping, it's still important to protect it from freezing temperatures. Proper insulation and installation techniques can help prevent damage in freezing conditions.

Disassembly and Repair

In the event of a mistake or repair, PEX fittings can be easily disassembled using the appropriate tools. Cut off crimp rings or cinch clamps, remove the tubing, and replace as needed.


With its flexibility, affordability, and ease of installation, PEX piping is a game-changer in the world of plumbing. Whether you're tackling a small repair or a major renovation, PEX offers unmatched versatility and reliability. Contact us at 954-504-6628 to learn more!
