Pipe Replacement and Repair in Temecula
When patching stops making sense, repipe once and stop chasing leaks.
A pinhole in a copper line is a repair. Three pinholes in three years is a pattern. In Temecula, where half the homes were built before 1998 and the water is very hard, that pattern shows up a lot.
We repair individual sections, reroute failed lines and repipe entire houses, usually overhead through the attic and walls so nothing under the slab carries pressure anymore.

PEX or copper?
- PEX is flexible, fast to install with fewer fittings in walls, resists scale and freeze damage better, and costs less. It must be kept out of direct sunlight and supported properly in hot attics.
- Type L copper lasts a long time in neutral water, handles heat well and some buyers prefer it. It costs more and is more sensitive to aggressive water and high velocity.
- Most Temecula repipes we price today are PEX, with copper stub-outs at fixtures. Either is code compliant. We price both if you want.
Polybutylene and older materials
Gray polybutylene supply pipe was used in many U.S. homes from about 1978 to 1995. Temecula's late-1980s and early-1990s neighborhoods sit inside that window, so some homes may have it or have had it partially replaced. Polybutylene fittings are known to fail without warning. If you see gray plastic pipe at the water heater or under sinks marked PB2110, have it evaluated.
What a repipe actually involves
We map every fixture, run new main trunk lines through the attic, drop branches down interior walls through small openings, connect each fixture and pressure test the whole system. Drywall openings are patched and ready for paint. Water is off during working hours and back on most evenings. The old lines under the slab are abandoned in place.
While the walls are open is the right time to add a pressure reducing valve if your street pressure is over 80 psi, and new shutoff valves at every fixture.
Time to repipe, not repair
Second slab leak in a few years
The copper under the slab is failing as a system.

Pitting corrosion through the wall of copper pipe.
Inspect other exposed sections for wall loss.
Low pressure everywhere
Scale buildup or failing galvanized sections in older homes.
Pressure test and check the PRV first.

Local factors that matter
Hard water
Scale narrows lines and pairs with pitting.
Pressure
Above 80 psi requires a PRV under the California Plumbing Code.
Hot attics
PEX must be supported and protected from UV and heat sources.
What drives repipe cost
Quoted in writing after a walkthrough.
Number of bathrooms and fixtures
The biggest factor.
Single vs two-story
Two-stories need more wall access.
PEX vs copper
Copper material and labor cost more.
