Step 1: Confirm Whether Your Home Needs a Whole House Repipe
First, look for the tell‑tale signs of failing plumbing. Frequent water stains on ceilings, low water pressure in multiple fixtures, or a sudden rise in your water bill often point to hidden leaks. You can also test for copper corrosion by running a simple visual check on exposed pipe sections in the basement or crawl space.
When in doubt, schedule a professional inspection. A qualified technician can run a pressure test , use a thermal camera, and check for pinhole leaks that are invisible to the naked eye.
Repipe OC offers a free on‑site assessment that includes a full diagnostic report.
If the inspection reveals widespread corrosion, repeated leaks, or old poly‑butylene piping, a whole house repipe is usually the best path forward. Minor issues may be fixed with spot repairs, but those are temporary fixes that often lead to bigger headaches later.
Step 2: Choose the Right Repipe Materials and Scope
The two most common materials for residential repiping are PEX‑A and copper. PEX‑A offers flexibility, freeze‑break resistance, and quick installation, while copper provides proven durability and high temperature tolerance.
Repipe OC sources US‑made Uponor PEX‑A and Rigid L‑type copper, matching the industry’s top recommendations. We match the material to your home’s layout, local code requirements, and budget preferences.
Scope matters, too. A full‑home repipe replaces every branch line, while a partial repipe targets only the most compromised sections. Full repipes eliminate hidden weak points, but they cost more and take longer.
Key Takeaway:Choose US‑made PEX‑A for flexibility and copper for proven longevity; let the scope align with the condition of your existing system.
For older homes with tight wall cavities, we often recommend PEX‑A because its bend radius reduces the need to cut large sections of drywall.
Step 3: Get an On‑Site Estimate, Permits, and a Written Plan
Once you’ve picked a material, the next move is a written proposal. The plan lists every pipe length, fixture, and any required structural work, such as drywall removal. For a clearer overview of the process, review what to expect from a repipe plumber in Orange County .
Repipe OC provides a flat‑rate estimate that includes all labor, materials, permits, and post‑install drywall repair. For help comparing project budgets, see this guide to whole house repipe cost and pricing options . No hidden fees.
Permits are mandatory in Orange County. Your plumber will pull the necessary permits from the local building department and schedule any required inspections.
When the estimate is approved, we lock in a start date. The written plan becomes a checklist that the crew follows to keep the job on schedule.
Permitting requirements and fees can vary by city. Review additional repiping information before work begins.
Step 4: Prepare the Property for Repiping and Installation
Preparation starts with clearing access points. Move furniture away from walls, protect flooring with drop cloths, and seal off the work area with HEPA‑grade dust barriers.
Our crew sets up a temporary water supply so you can still use the kitchen sink while work proceeds in other rooms.
We also take photos of existing fixtures before demolition. This helps us match new pipe runs to the exact locations of sinks, toilets, and appliances.
During demolition, we use low‑vibration tools to minimize disruption to finished spaces.
Pro Tip:Ask the crew to label each pipe segment as it’s installed. Clear labeling speeds up the final inspection.
Watch the video below for a walk‑through of a typical preparation day.
By the end of Day 1, most of the old piping is removed and the new PEX or copper is in place behind the walls.

Step 5: Test, Inspect, Restore, and Protect the New System
After installation, we conduct a pressure test at 150 psi for at least 15 minutes. This verifies that every joint holds and that there are no hidden leaks.
Next, a city inspector reviews the work, checks the permits, and signs off on the final inspection. Only then do we close up the walls.
Our crew restores drywall using the same texture and paint finish as the original surfaces. The result looks as if the walls were never opened.
Finally, we hand you a warranty packet that includes a 25‑year transferable guarantee on both materials and labor. This warranty outlasts the typical 10‑year workmanship coverage offered by many competitors.
