Copper vs Flex vs Stainless: Choosing the Right Water Heater Connections

The pipes connecting your water heater affect leak risk and water quality. Here is how the options compare.

Commercial water heaters installed in a mechanical room for a Sacramento-area business - Copper vs Flex vs Stainless: Choosing the Right Water Heater Connections

Key takeaways

  • Copper with lead-free solder is durable and safe for drinking water.
  • Stainless steel flex lines resist corrosion and ease future service.
  • Avoid mixing metals without dielectric protection.

Old galvanized connections rust from the inside, restrict flow and can discolor your water. New installations deserve better.

Copper with lead-free solder

Rigid copper is long-lasting and clean. We use lead-free solder that meets drinking water standards.

Stainless steel flex connectors

Flexible, corrosion-resistant and easy to service, which makes them a great choice for seismic movement.

Rust-resistant piping

Replacing corroded galvanized nipples with corrosion-resistant fittings prevents leaks and rusty water.
