Copper: The Undisputed Classic

Copper has been the gold standard in plumbing for decades. Known for its exceptional durability and resistance to corrosion, copper pipes can last anywhere from 50 to 70 years when properly installed. Because copper is a metal, it’s strong, resistant to UV rays, and can handle high temperatures and pressures.

Another major advantage of copper is that it’s naturally biostatic, meaning it discourages the growth of bacteria. It’s also a recyclable, environmentally friendly material.

However, copper does have some drawbacks. It’s one of the most expensive pipe materials on the market, both in terms of material and installation costs. Copper pipes also require soldering, which means professional installation is a must. In addition, copper can corrode over time in areas with highly acidic water, leading to pinhole leaks or discoloration.

Best for: Homeowners who value long-term reliability and are willing to invest in premium materials for decades of dependable performance.

PVC: The Budget-Friendly Option

Polyvinyl chloride (PVC) pipes are a popular choice for cold-water lines and drain lines. Lightweight, easy to install, and resistant to rust and corrosion, PVC is one of the most affordable piping options available. Its smooth interior helps maintain good water flow, and it’s not prone to buildup or scaling like metal pipes can be.

Because of its low cost, PVC is often used for main water lines running underground. It’s also resistant to chemical damage, making it suitable for various applications beyond plumbing.

That said, PVC isn’t ideal for every situation. It can’t withstand high temperatures, so it’s not suitable for hot water lines. It can also become brittle over time, especially when exposed to direct sunlight or freezing temperatures. Repairs and replacements can be more difficult since PVC is rigid and requires cutting and gluing to modify.

Best for: Homeowners looking for a cost-effective solution for cold-water supply lines or underground installations.

PEX: Renowned For Flexibility

Cross-linked polyethylene (PEX) has quickly become one of the most popular plumbing materials in modern homes. Its flexibility allows it to bend around corners and through walls with minimal fittings, reducing the risk of leaks. PEX is resistant to corrosion, mineral buildup, and freezing, making it an excellent choice for both hot and cold water lines.

Another big advantage of PEX is its ease of installation. Because it doesn’t require soldering or glue, it’s faster and cheaper to install than copper or PVC as long as you hire a local plumbing repair service. PEX is also quieter because water flow through PEX pipes produces less noise and vibration compared to rigid materials.

However, PEX isn’t without its downsides. It can’t be exposed to direct sunlight for long periods, as UV rays can degrade the material. While highly durable indoors, it’s not the best option for exterior or above-ground plumbing.

Best for: Homeowners seeking an affordable, flexible, and long-lasting plumbing solution that performs well in most environments.
