The answer to 'which is better water line or' is that there is no single 'better' option, as the choice between water lines and water pipes depends on your specific needs and situation. Water lines and water pipes both have their own advantages and disadvantages that should be carefully considered.
Water lines, which are typically made of copper or plastic, are generally more durable and have a longer lifespan than water pipes. They are also less prone to leaks and are easier to maintain. Water pipes, on the other hand, are often made of galvanized steel or PVC and can be more vulnerable to corrosion and damage over time. However, water pipes may be a more cost-effective option, especially for smaller home projects.
