There is no one size fits all answer to this question as the best type of pipe for your home plumbing system will depend on a variety of factors. However, some of the most popular types of pipes used in residential applications include PVC, PEX, and copper. Each type has its own advantages and disadvantages, so it is important to consider your budget, local climate conditions, and any other specific requirements when making a decision. In new construction, consult with your engineer of record to find the best solution for your house. For example, PVC pipes are typically less expensive than copper or PEX and are easier to install, while copper is more durable and may be the best choice for cold climates.
