Selecting the right type of pipe is crucial for ensuring a reliable and long-lasting plumbing system. The most commonly used options are PVC, copper and PEX, each offering different benefits depending on the needs of your project.
PVC Pipe
Polyvinyl chloride, or PVC, is a cost-effective and lightweight option, ideal for drainage and waste systems. PVC pipes are easy to install and resistant to corrosion, making them a common choice for residential and commercial plumbing projects. The smooth interior prevents blockages, ensuring consistent water flow.
The main drawback of PVC pipes is their sensitivity to heat, which can cause warping or brittleness over time. Additionally, PVC is unsuitable for outdoor use without UV protection, as prolonged exposure to sunlight can degrade the material.
Copper Pipe
Copper pipe has long been a trusted choice for plumbing due to its strength, durability and resistance to corrosion. They are especially valued for carrying drinking water safely over long periods, as they do not affect water quality. Copper also tolerates extreme temperatures, making it suitable for both hot and cold water systems.
However, copper pipes can be expensive compared to other materials, and they are prone to freezing in cold climates unless properly insulated. They are also a target for theft due to their high scrap value. Despite these drawbacks, copper pipes remain a durable and reliable choice for plumbing systems when installed by professionals.

PEX Pipe
Cross-linked polyethylene or PEX pipes are known for their flexibility and ease of installation. They are resistant to corrosion, rust and scaling and can navigate tight spaces with minimal fittings. PEX is a great choice for both hot- and cold-water systems, and installation is faster as it doesn’t require soldering.
However, PEX pipes are sensitive to UV rays, which can weaken them if exposed to sunlight. They also need to be installed with care in areas prone to freezing temperatures. Despite these limitations, PEX is a flexible, cost-effective and efficient plumbing solution.
