As a master plumber serving Dallas and the surrounding areas for decades, I’ve worked with just about every type of pipe material you can think of—copper, cast iron, galvanized steel, and yes, plastic. Over the years, plastic pipework has become increasingly popular in residential plumbing systems, and for good reason. But like anything, it comes with both benefits and drawbacks.
In this blog, I’ll walk you through what Dallas homeowners need to know about plastic plumbing pipes, including their types, pros and cons, typical pricing, and when it makes sense to go plastic over metal.
What Is Plastic Pipework?
Plastic pipework refers to plumbing pipes made from PVC (polyvinyl chloride), CPVC (chlorinated polyvinyl chloride), PEX (cross-linked polyethylene), or ABS (acrylonitrile butadiene styrene). Each of these materials has its own ideal use case depending on the project—whether it’s drainage, supply lines, or repiping an entire house.
Types of Plastic Pipes Used in Dallas Homes
PVC: Commonly used for drain, waste, and vent (DWV) systems.
CPVC: Similar to PVC, but rated for hot water lines.
PEX: Flexible, durable, and ideal for water supply lines.
ABS: Black plastic pipe typically used for drainage and vent systems.
In Dallas, we most commonly use PEX and PVC for residential installations and repairs due to their durability and cost-effectiveness.
Pros of Plastic Plumbing Pipes
Affordability
Plastic pipes are significantly less expensive than copper or other metal pipes. For budget-conscious homeowners in Dallas, this can make a big difference—especially in large projects like whole-home repiping.
Corrosion-Resistant
Unlike metal pipes, plastic won’t rust or corrode over time. That’s a big plus here in North Texas, where water quality can vary by neighborhood and mineral content can take a toll on older metal systems.
Flexible Installation
Especially with PEX piping, installation is faster and easier thanks to its flexibility. That means fewer fittings, faster labor, and less disruption to your home.
Energy Efficient
Plastic pipes are better insulators than metal. PEX in particular retains heat well, helping improve energy efficiency in your hot water delivery system.
Quiet Operation
Plastic pipes tend to be quieter than metal ones. You’re less likely to hear loud bangs or “water hammer” noises from behind your walls.
Cons of Plastic Pipework
Lower Heat Resistance
While CPVC and PEX can handle hot water, they still have lower heat tolerances compared to copper. That can be a concern for homeowners with high-heat applications.
UV Sensitivity
PEX and PVC pipes degrade when exposed to sunlight, so they’re not suitable for outdoor or exposed installations unless properly shielded.
Shorter Lifespan Compared to Copper
While plastic pipes can last 40–50 years, copper can often last even longer when properly maintained. That said, copper is also more expensive and more prone to theft.
Potential for Chemical Leaching
There’s some debate over chemical leaching from plastic pipes, particularly in high-heat water. While modern plastic piping is certified safe, some homeowners still prefer metal for drinking water lines.
How Much Does Plastic Pipework Cost in Dallas?
Here’s a ballpark idea of what you might expect to pay for plastic pipe installations in the Dallas area:
PEX repiping a 2-bathroom home: $2,500 – $4,000
PVC drain replacement: $2,500 – $7,000 depending on length and access
Spot repairs or small additions: $300 – $1,000
Of course, these are general ranges. Factors like wall access, crawl space vs. slab foundation, and permit requirements will all affect the final cost. At Total Plumbing, we always provide upfront pricing with no hidden fees.
FAQs: What Dallas Homeowners Ask Us About Plastic Plumbing
Is PEX pipe better than copper?
It depends. For many Dallas homes, PEX offers a reliable, cost-effective alternative to copper. It’s easier to install, resists corrosion, and performs well in both hot and cold weather.
How long do plastic pipes last in Texas homes?
PEX and PVC typically last 40 to 50 years. Proper installation and protection from UV exposure are key to maximizing lifespan.
Can you mix plastic and copper pipe?
Yes—but it needs to be done correctly using approved fittings and transition joints to avoid galvanic corrosion or leaks.
Is plastic pipe safe for drinking water?
Absolutely. Modern PEX and CPVC pipes are NSF-certified for potable water and are widely used in new construction across the country.
