Copper vs. PEX: Choosing Repipe Material
Two materials dominate residential repipes, and both are good. Here's how they actually compare, so you can choose with confidence.

Call (562) 245-5416 Request ServiceIs PEX pipe safe for drinking water?
Yes. PEX pipe used in U.S. homes is certified to NSF/ANSI 61 for drinking-water safety, the same standard applied to other approved plumbing materials. An independent product certification mark on the pipe tells you it passed.
Does copper pipe really last longer than PEX?
Copper has a long, proven track record of decades of service, while PEX is newer but has performed well for over thirty years in real installations. In Lakewood-area homes, water chemistry matters more than the material's reputation, aggressive or acidic water attacks copper, while PEX resists corrosion entirely.
Will PEX burst like my old pipes did?
No repipe material is indestructible, but PEX handles pressure surges and minor ground movement better than rigid pipe because it flexes instead of cracking. It still needs a pressure regulator if your home's water pressure runs high.
Can you repipe just part of a house with PEX?
Yes, partial repipes and hybrid systems are common, copper-to-PEX transitions use approved fittings. But if your whole system is aging galvanized or corroded copper, a full repipe usually makes more sense than patching sections one at a time.
Which should I pick for my Lakewood-area home?
Both are solid choices. PEX usually wins on corrosion resistance, installation speed, and flexibility through tight walls; copper wins when you want a rigid, time-tested metal system. Call (562) 245-5416 and we'll look at your current piping and water conditions before recommending one.
When the choice is a full repipe, our whole-house repiping service handles the complete swap; for a single failing copper run, copper pipe repair may be all you need. Either way, check the standard behind the material: PEX used in U.S. homes is certified to the NSF/ANSI 61 drinking-water standard from NSF International, and the U.S. EPA’s drinking-water guidance explains how water quality rules apply to home plumbing.
Get the right material for your water. We'll inspect your current pipes, check your water conditions, and recommend copper, PEX, or a hybrid, with the reasoning explained in plain words.

Is PEX pipe approved by plumbing codes in California?
Yes, PEX is an approved plumbing material under the California Plumbing Code when it is installed to the code's requirements, using approved fittings and methods. Local permit rules can still vary, so a permitted repipe follows the code edition your city enforces and the manufacturer's installation instructions for that pipe.
Does PEX change how drinking water tastes?
Most homeowners notice no taste difference after switching to PEX, and the material is certified for drinking-water contact. A faint plastic taste can appear in brand-new lines and usually fades after the system is flushed and used for a few days. Persistent taste or odor problems deserve a separate check of the water supply itself.
Can PEX be used outdoors or in direct sunlight?
PEX is designed for indoor use and breaks down under prolonged ultraviolet exposure, so it should not run outdoors in direct sunlight. Exterior or exposed sections call for a material suited to the weather, such as copper, with proper insulation and protection. Inside walls and ceilings, away from sunlight, PEX performs as intended.
