Patch Again or Replace Everything
Whole house repiping in Mission Viejo, CA replaces the water supply lines throughout the house. It is a big job, so it is worth being sure. A single failed joint is a repair. Several failures in different spots point to the pipe.
| Sign | What it suggests | Next step |
|---|---|---|
| Second or third pinhole leak in a few years | The pipe wall is thinning along its length | Inspect, then discuss repiping |
| Green or white crust on copper | Corrosion is active on the outside | Check nearby sections |
| Rusty or brown water from hot taps | Corrosion inside older steel pipe | Test and inspect the line |
| Low pressure at several fixtures | Mineral scale narrowing the pipe | Test and inspect the line |
| Repeated leaks in the same area | A localized failure, such as a rubbing or a bad joint | A reroute may be enough |
Not every older house needs a repipe. The best way to decide is to see the pipe, test the pressure and review the repair history.
Pinholes in Orange County Copper
Orange County has a documented history with pinhole leaks in copper. In Ladera Ranch a settlement reached in 2015 covered hundreds of homes built between 2003 and 2013, according to ABC7. Plaintiffs blamed chloramine and sulfites in the water for pitting the pipe from the inside, and the builder disputed that the pipe was defective.
Moulton Niguel's 2022 report says its water is disinfected with chloramine and near 16 grains per gallon in hardness. Neither fact proves a problem in your pipe. They are reasons to take repeat leaks in copper seriously and to ask a plumber to inspect the rest of the line.
For a single leak, see burst pipe repair. For a hidden leak with no visible source, see leak detection.
Copper or PEX
Both are common supply pipe materials. Copper is rigid, soldered or brazed and has a long record. PEX is flexible plastic tubing that connects with fittings and can run through walls with fewer joints.
| Question | Copper | PEX |
|---|---|---|
| Installation | More cutting and joining, and more open wall time | Often fewer joints and less wall opening |
| Water chemistry | Reacts with some water, which can cause pitting | Does not corrode, but has its own handling rules |
| Heat and sunlight | Handles both | Not for outdoor or sun-exposed runs |
| Repair later | Soldering in a wall can be tight | Fittings can be quicker to replace |
No material is right for every house. Ask the plumber why a material fits your house and what the alternatives would mean.
What the Work Looks Like
Plan the routes
The plumber maps the new supply lines from the main to each fixture and marks the access points.
Open and replace
Small openings are cut in drywall. New pipe is run and connected, and the old lines are capped or removed.
Test and close
The system is pressure tested before any wall is closed. Drywall patches are made, and painting is a separate step.
Expect the water to be off for part of each working day, and expect dust. Ask how long the house will be without water and where patched walls will be, because drywall finish is often done by another trade.
Cost Factors
- Number of fixtures and the length of piping.
- House size, number of stories and slab or crawl space.
- Pipe material and fittings.
- How much drywall is opened and who repairs it.
- A permit and inspection, which repiping typically requires.
Insurance rarely pays for a repipe, though it may cover the water damage from a sudden leak. Read the policy and ask before work.
