1. Repipe OC (Our Top Pick) — Full‑service copper repiping in Orange County

 Repipe OC handles residential and commercial whole‑home repipes from inspection to final patching. The crew maps pipe routes, protects your home with tarps, and pulls out old lines before installing new copper or PEX. Every job ships with a 25‑year transferable warranty that covers parts and labor, a rarity in the market.

Homeowners love the one‑stop approach: you get a free on‑site estimate, city‑permit handling, and 24/7 emergency support. The larger crew can finish most homes in one to two days, and many quotes include drywall repair so you avoid surprise add‑ons.

One downside is the higher hourly rate that comes with the full‑service package, and the service area focuses on the 949 ZIP region. If you live outside that zone you’ll need another provider.

Pro Tip:Schedule your free on‑site estimate early in the week; crews often have open slots for faster start dates.

2. Type L Copper — A thicker‑wall choice for long‑term ownership

Type L copper has a medium wall thickness that balances cost and durability. It typically lasts 50‑100+ years when water chemistry stays neutral and pressure stays moderate.

Research shows that thicker walls give a safety margin in acidic or high‑pressure systems. In Orange County, where water hardness averages 13 grains per gallon, the extra wall helps resist pinhole leaks that softer pipes suffer.

The material costs about $8‑$21 per foot, making it pricier than PEX but cheaper than the ultra‑thick K‑type. Installation takes longer because each joint must be soldered, which adds labor hours.

For homes that value a classic look and plan to stay put for decades, Type L offers a solid middle ground.

3. Type M Copper — A lighter‑wall option where conditions allow

Type M copper features a thinner wall, which cuts material cost but also reduces life expectancy to around 40‑60 years under typical conditions.

In areas with soft water and low acidity, the thinner wall can still perform well. However, Orange County’s hard water can accelerate corrosion, so you may see leaks sooner than with Type L.

The lower price point makes Type M attractive for budget‑focused projects, especially when the repipe includes many hidden runs where future access is limited.

One risk is that thin‑walled joints can fatigue faster under temperature swings, leading to early failures in hot‑water loops.

4. PEX‑A and PEX‑B Alternatives — Flexible options when copper is not the best fit

PEX‑A uses the Engel cross‑linking method, giving the highest flexibility and burst resistance. PEX‑B, made with the silane method, is slightly stiffer but costs a bit less.

Both run 30‑50% cheaper than copper per linear foot and install up to three times faster because they snake through walls without soldered joints. In Orange County’s hard‑water environment, PEX doesn’t corrode, making it a low‑maintenance choice.

The main drawback is that PEX can’t be left exposed to UV light and isn’t as heat‑resistant as copper for long runs near water heaters.

Many homeowners adopt a hybrid system: copper for exposed hot‑water lines and PEX‑A for in‑wall branches. That gives you copper’s heat tolerance where you need it and PEX’s flexibility elsewhere.

FAQ: Repiping With Copper Pipes

How long does copper piping actually last?

Copper pipes typically last 50‑70 years, though the exact figure depends on pipe type, water chemistry, and installation quality.

Is copper better than PEX for hard water?

Copper can corrode faster in hard water, especially if the pH is low; PEX does not react to minerals, so it usually holds up better in Orange County’s hard‑water conditions.

What does a 25‑year warranty cover?

Repipe OC’s warranty covers both parts and labor for 25 years, transferable to new owners, and includes city‑inspection fees and drywall repair.

Do I need a permit for a full repipe?

Yes, Orange County requires a plumbing permit for any whole‑home repipe; Repipe OC handles the paperwork and schedules the city inspection for you.

Can I mix copper and PEX in the same house?

Mixing is common: copper for exposed hot‑water runs and PEX for hidden in‑wall branches gives you durability where it matters and flexibility elsewhere.

How much will a copper repipe cost?

Costs range from $8 to $14 per square foot installed, depending on home size, access difficulty, and material grade. Financing options can spread the payment over months.
