PEX vs Copper, and Why Some Plumbing Pipes Are White
PEX vs copper comes down to flexibility and fittings: PEX is plastic tubing that bends around corners, copper is rigid metal joined with solder. The white or cream pipe you see is usually CPVC for water or PVC for drains.

What you’re seeing in this video
Three jobs, three pipe types. A SwiftPro tech with long hair runs a length of copper past a home bar. Copper is the rigid, orange-brown metal line that's been the standard for decades.
A second tech in a SwiftPro cap works at a manifold, a brass bar with a row of valves, with PEX lines running off it. PEX is the flexible plastic tubing, often red for hot and blue for cold, that runs from one central spot to each fixture.
The last shot shows CPVC pipe in an open wall chase. CPVC is the cream-colored plastic rated for hot and cold water. Bright white PVC looks similar but belongs on drains and vents.
Why it matters in your house
- Don't judge a pipe by color alone. White in a wall could be CPVC supply or PVC drain, and the printing on the side tells you which.
- PEX has fewer joints behind the wall, and every joint you skip is one less place to leak. Copper handles heat and sunlight better, so it's often used right at the water heater.
- Adding a fixture? Match what's there or use a proper transition fitting. Mixing materials with the wrong connector is a common source of slow leaks.
Is PEX better than copper for a house?
Neither wins everywhere. PEX installs faster, bends around framing with fewer fittings and handles freezing better. Copper lasts a long time, stands up to heat and doesn't mind sunlight. Plenty of houses end up with both: copper near the water heater, PEX out to the fixtures. Water chemistry and what's already in your walls usually decide it.
