Pex Piping

Why PEX Piping Is a Game-Changer for Texas Homes!

If you own a home in Texas—whether it’s brand new or you’ve lived there for years—you’ve probably heard the term PEX piping floating around. Maybe your plumber mentioned it during a renovation. Or maybe you saw those colorful red and blue tubes under a sink and wondered, “What is that?”

Well, here’s the good news: PEX is one of the biggest advancements in residential plumbing in decades, and it’s especially great for homes in Texas.

Why? Because it handles our scorching summers, hard water, and even those surprise winter freezes better than old-school copper or PVC.

Let’s break down 10 key facts about PEX piping that every Texas homeowner should know—so you can make smarter decisions about your home’s plumbing.


10 Essential Facts About PEX Piping You Need to Know


1. It’s Super Flexible (No More 90-Degree Fittings!)

Unlike rigid copper or PVC pipes, PEX is flexible—like a garden hose, but stronger. This means it can bend around corners, joists, and studs without needing a bunch of elbows and connectors.
 

Why it matters for you:  Fewer joints = fewer places for leaks to develop. Plus, faster installation means lower labor costs during plumbing repairs or upgrades. 

 

 

2. Resists Scale & Chlorine (Hello, Texas Hard Water!)

If you’re in Central or North Texas, you know the struggle: hard water. It leaves spots on dishes, clogs showerheads, and can destroy metal pipes over time.

PEX doesn’t corrode or build up scale like copper. It’s also resistant to chlorine, which many Texas cities add to their water supply.
Bottom line: PEX lasts longer in our water conditions—and keeps your plumbing flowing smoothly.


3. Handles Freezes Better Than Copper (Yes, Even in Texas!)

Remember Winter Storm Uri in 2021? Many Texas homes suffered burst pipes when temps dropped.

Here’s the good news: PEX can expand when water freezes, then return to shape when it thaws—unlike copper or PVC, which often crack or burst.
 

Important: PEX isn’t freeze-proof—just more forgiving. You should still insulate pipes and keep heat on during cold snaps.

4. Three Types: PEX-A, PEX-B, and PEX-C

Not all PEX is created equal. There are three types, based on how the plastic is cross-linked:

PEX-A – Most flexible, best freeze resistance (made with the Engel method)  

PEX-B – Slightly stiffer, common in big-box stores  

PEX-C – Tightly cross-linked, often thinner wall  
 

For Texas homeowners: PEX-A is ideal for tight spaces and freeze-prone areas, but PEX-B works great for most retrofits.


5. Color-Coded for Hot & Cold (No Guesswork!)

You’ll usually see PEX in red, blue, or white:

- 🔴 Red = Hot water lines  
- 🔵 Blue = Cold water lines  
- ⚪ White or Gray = Can be used for either (just label them!)
 

Pro tip: Use color coding even in repairs—it helps future homeowners (or plumbers) understand your system fast.
 

6. UV Light Will Destroy It (Keep It Indoors!)

PEX breaks down when exposed to sunlight or UV rays. Just 60 days of direct sun can weaken it.
 

Texas tip: Never leave PEX exposed in attics, outdoor lines, or unfinished walls with sunlight. If you must run it outside, protect it with conduit or insulation.


7. Certified for Safe Drinking Water

All PEX used in the U.S. must meet NSF/ANSI Standard 61 for drinking water safety. Look for the certification mark when buying.

No weird plastic taste. No harmful leaching. Just clean, safe water—perfect for your family.


8. Multiple Ways to Connect It (But Tools Matter)

You can join PEX using:
- Crimp rings (copper)
- Clamp (cinch) rings (stainless steel)
- Push-to-connect fittings (like SharkBite)
- Expansion rings (for PEX-A, most secure)
 

For DIYers: Crimp and clamp systems are affordable and reliable with the right tools.


9. Fewer Leak Points = More Peace of Mind

Because PEX is flexible and needs fewer fittings, there are fewer places for leaks to happen. That means fewer water damage risks and lower repair bills down the road.
 

Bonus: Less clutter in tight spaces like under sinks or in utility closets.


10. Built to Last 50+ Years

With proper installation, PEX piping can last over 50 years. That’s longer than most roofs or HVAC systems!

It doesn’t corrode, scale, or degrade easily—making it a smart long-term investment for your Texas home.


PEX-A vs PEX-B vs PEX-C: Which Is Right for You? 

PEX-A - Tight spaces, cold areas - $ - Freeze Resistant - 5 Stars

PEX-B - General repairs, DIY - $$ - Freeze Resistant 3.5 Stars

PEX-C - Straight runs, tight walls - $$ - Freeze Resistant 3 Stars
 

For most Texas homeowners, PEX-B is a solid, cost-effective choice. But if you’re in a freeze-prone area (like North Texas), PEX-A is worth the extra cost.


Common PEX Mistakes Texas Homeowners Make

- ❌ Leaving PEX exposed to sunlight during installation  
- ❌ Using the wrong fittings (e.g., not rated for PEX)  
- ❌ Not supporting pipes every 32 inches (required by code)  
- ❌ Forgetting to flush the system before use (can cause cloudy water)
 

Pro tip: Always follow local plumbing codes—Texas adopts the IPC (International Plumbing Code), but some cities have amendments.


FAQs About PEX Piping
 

Q: Can I install PEX myself? 
A: Yes! With the right tools (cutter, crimper, gauge), DIYers can handle small repairs or upgrades. But for full-home repipes, hire a licensed plumber.
 

Q: Is PEX safe for drinking water?  
A: Yes—only use PEX labeled NSF/ANSI 61. All major brands meet this standard.
 

Q: Can PEX be used for radiant floor heating? 
A: Absolutely! PEX is the #1 choice for radiant heating systems in Texas homes.
 

Q: Does PEX affect water pressure?  
A: Not if sized correctly. PEX has similar flow rates to copper.


Final Thoughts: PEX Is Perfect for Texas Homes

Whether you’re building new, renovating, or just tired of leaky pipes, PEX piping is a smart, durable, and cost-effective choice—especially in Texas.

It handles our hard water, extreme temps, and tight crawlspaces better than traditional materials. And with a lifespan of 50+ years, it’s a true long-term win.

So next time your plumber mentions PEX, you’ll know exactly why it’s the modern standard.
