The answer to 'best pipe' is that the best pipe for a home plumbing system depends on the specific application and requirements. Some of the most common and durable pipe materials used in residential plumbing include copper, PEX (cross-linked polyethylene), and PVC (polyvinyl chloride).
Copper pipes are known for their strength, corrosion resistance, and long lifespan, making them a popular choice for water supply lines. PEX pipes are flexible, easy to install, and resistant to freezing, making them a good option for both hot and cold water lines. PVC pipes are lightweight, affordable, and resistant to corrosion, making them a common choice for drain, waste, and vent (DWV) systems.
