Copper vs. PEX vs. PVC: Which Pipes Are Best for Repiping?

If your home is from the last millennium and still has its original plumbing, then chances are it’s due for repiping. In that case, you ought to know about your options.

In this brief article brought to you by Mr. Rooter Plumbing, we share our two cents on what every homeowner should know about copper versus PEX versus PVC.

Copper Pipes: The Time-Tested Standard

Copper has been, ironically, the gold standard for residential plumbing for over 70 years. Properly installed, copper plumbing can last for 50 years or more. In addition to longevity, copper pipes are known for:

• Reliability: Resistant to UV damage and won’t become brittle over time.
• Heat Resistance: Handles high temperatures and pressure well.
• Naturally antimicrobial: Copper discourages bacterial growth inside pipes.
• Environmentally friendly: Fully recyclable and contains no synthetic chemicals.

With that said, copper is the more expensive material compared to PEX and PVC. The installation is also more time- and skill-intensive as it requires soldering.

All in all, copper remains ideal for visible plumbing, water heaters, and areas exposed to sunlight or heat. It’s also preferable for homeowners who want long-lasting plumbing with minimal maintenance needs.

PEX Pipes: The Modern Favorite

PEX, with stands for cross-linked polyethylene, is the flexible plastic piping that’s become the go-to choice for most modern plumbing installations. Homeowners appreciate its low cost and any plumber will tell you they love that PEX is highly adaptable and easy to install – even in tight spaces.

The flexible nature of PEX makes it easy to bend around corners (without fittings, which are likely to leak), and it also reduces the risk of bursting since PEX expands slightly when frozen. The material even reduces “water hammer” noise from sudden pressure changes.

The bad news is that PEX is awfully UV sensitive, so it should NOT be installed in direct sunlight. In rare cases, rodents can even chew through exposed PEX. Finally, some municipalities have limitations or require specific fittings.

All things considered, we like that flexible PEX can be snaked through walls with minimal demolition. It’s also highly efficient for pipe repair, since new sections can be quickly connected with crimp or push-fit fittings.

PVC Pipes: The Dependable Drainers

Polyvinyl chloride, or PVC, is a rigid plastic pipe used primarily for drain, waste, and vent systems. That is, PVC is not typically used for hot water supply. It’s extremely common in both residential and commercial buildings due to its durability and low cost. It’s corrosion-proof and minimizes clog-risk thanks to its smooth interior.

To be clear, PVC is not the right material for pressurized water supply, but it’s great for drain pipe repair and replacements. PVC is ideal for drainage lines, vent systems, and sewer pipes. In Florida homes, it’s often used beneath slabs or as part of septic and wastewater systems.

Choosing the Right Material

The right choice depends on your home’s needs, local water conditions, and budget – as well as building codes, local regulations, etc. A licensed plumber can evaluate these factors and help you choose the right material for your job.
