When should I consider replacing my pipes?

You should consider pipe replacement if you notice frequent leaks, discolored water, low water pressure, or if your plumbing system is over 30–50 years old. Aging materials like galvanized steel or lead should be replaced immediately.

What types of pipes are best for home plumbing?

• PEX: Flexible, affordable, and great for most modern homes.
• Copper: Durable and long-lasting, but more expensive.
