Why PEX
PEX vs Copper
See why PEX is the modern standard for residential and commercial water supply piping.
No More Pinhole Leaks - PEX Repiping
Key Benefit

No More Pinhole Leaks

Copper corrodes from the inside out, creating pinhole leaks. PEX is corrosion-resistant and virtually leak-proof at joints.

Quiet Operation - PEX Repiping
Quality of Life

Quiet Operation

No more water hammer or pipe noise. PEX flexes instead of vibrating, eliminating the banging sounds copper makes.

200+ Year Material - PEX Repiping
Long Term

200+ Year Material

PEX material is rated to last over 200 years. It won't corrode, pit, or scale like copper does over time.

Faster Installation - PEX Repiping
Minimal Disruption

Faster Installation

PEX is flexible and requires fewer connections than rigid copper. Most whole-home repipes complete in 1-2 days.

Cost Effective - PEX Repiping
Save Money

Cost Effective

PEX material and installation costs less than copper. Lower material cost, faster labor, fewer fittings.

✦ See the Difference With Your Own Eyes
Corroded Iron. Blue Epoxy Liner. Same Pipe.

These are real pipes pulled from Orange County properties. The corroded cast iron on the outside — that's what's under your building right now. The smooth blue liner on the inside — that's what CIPP delivers. No digging. No replacement. Just a new pipe inside your old one.

The Process
How CIPP Pipe Lining Works
From inspection to warranty — here's what happens when you call LoMonaco Coast for trenchless pipe rehabilitation.
01
📹

Camera Inspection

HD camera survey maps your entire pipe system. We identify every crack, root, offset, and defect. Full video report included.

02
🌊

Hydro Jet Cleaning

High-pressure water (up to 4,000 PSI) clears roots, grease, scale, and debris. Pipes are prepped clean for the liner.

03
🔧

CIPP Liner Install

NuFlow epoxy-saturated liner is pulled into place inside the existing pipe. UV or ambient cure creates a new pipe-within-a-pipe. No digging.

04
✅

Final Inspection

Post-cure camera inspection verifies 100% coverage. You get a video of the finished liner plus a 50+ year warranty.

"One of the most professional if not THE most professional contractor my wife and I have ever dealt with. From start to finish we were kept in the loop and they stayed true to everything they communicated to us. He sent in a team of eight guys who just swarmed over the house and got it done. It was poetry in motion!"

FAQ
PEX Repiping FAQ
Common questions about pex repiping services.
What is PEX piping?
PEX (cross-linked polyethylene) is a flexible plastic piping material used for water supply lines. It's the modern replacement for copper, offering superior durability, flexibility, and corrosion resistance.
How do I know if I need a repipe?
Signs you need repiping include pinhole leaks, discolored water, low water pressure, recurring pipe repairs, visible corrosion on exposed pipes, and your home being 25+ years old with original copper.
How long does a whole-house repipe take?
Most residential repipes are completed in 1-2 days. We work efficiently to minimize disruption — you'll have running water back the same day in most cases.
Is PEX better than copper?
For most applications, yes. PEX is more flexible, resists corrosion, handles freezing better (it expands instead of bursting), costs less, installs faster, and lasts longer. Copper is still used in some commercial applications.
Will repiping damage my walls?
We make small, strategic access points and patch everything when finished. Our goal is minimal cosmetic impact. Most homeowners are surprised at how clean the process is.
Do you repipe commercial buildings?
Yes. We handle multi-unit residential, hotels, and commercial water supply repiping. Call (949) 933-3871 to discuss your project scope.
