PEX Piping Installation in Norwalk & La Mirada
PEX (cross-linked polyethylene) piping has become the standard replacement material for aging copper and galvanized water lines. It resists corrosion, handles freeze-thaw cycles better than rigid pipe, requires fewer joints, and costs significantly less than copper. For homeowners dealing with pinhole leaks, low water pressure, or discolored water from old pipes, PEX repiping solves the problem for decades.
Our plumbers install PEX using manifold systems that give you individual shut-off control at every fixture. This means you can isolate a single sink or toilet for repair without shutting off water to the entire house. We have repiped hundreds of homes throughout Norwalk, La Mirada, and surrounding cities using PEX, and we stand behind every installation.
Our PEX Piping Process
System Design
We map your existing plumbing layout and design the new PEX system with a central manifold. Each fixture gets a dedicated home run line, which maximizes pressure and provides individual control.
Old Pipe Removal
We remove old copper or galvanized lines section by section, working room by room to minimize disruption. In many cases, old lines can be abandoned in place if removal would cause excessive wall damage.
PEX Installation
New PEX lines are run from the manifold to each fixture using crimp or expansion fittings. PEX flexibility allows routing through tight spaces that rigid pipe cannot reach, reducing the number of wall openings needed.
Testing & Restoration
We pressure test the entire system at 80 PSI for a sustained period before closing walls. All drywall patches are textured to match, and we clean up completely before leaving.
We serve Norwalk, La Mirada, and 20 surrounding Southern California cities. Learn more about all our plumbing services or call 562-219-4085 for same-day service.
