Final Thoughts

Copper pipes are still a fantastic choice, especially for long-term durability, but they come at a price. If you’re dealing with underground plumbing or high-pressure lines, Type K or L is your best bet. If you’re on a budget, Type M will get the job done. But if you’re open to modern alternatives, PEX might save you some serious cash.
