Best Choices for Repiping New Construction Homes

New homes need fresh plumbing that will last decades. In Orange County, the right repiping choice can add years of peace of mind. Below are the five top options, plus a quick checklist to help you decide.

1. Repipe OC (Our Top Pick) — Full‑service repiping with a 25‑year warranty

 Repipe OC handles every step of a whole‑home repipe, from inspection to final city sign‑off. The crew pulls out old lines, installs premium piping, and patches walls so the work is invisible. Homeowners love the 25‑year transferable warranty that covers both parts and labor, a guarantee you rarely find elsewhere.

Because the company works across all Orange County neighborhoods, Laguna Niguel, Irvine, Newport Beach, and more, it knows local code requirements inside out. That means fewer delays and smoother inspections. Repipe OC also offers 24/7 emergency support, so a burst pipe won’t keep you up at night.

We back this pick with data: only 27 % of pipe‑material listings include a warranty, yet Repipe OC provides a full 25‑year term. That transparency gap makes it the safest bet for new‑build owners.

Pro Tip:Schedule a free on‑site estimate early in the build phase to lock in the warranty before the home is occupied.

2. PEX — Flexible, future‑proof piping for modern homes

PEX (cross‑linked polyethylene) is a flexible plastic that resists corrosion and can bend around obstacles. It works for both hot and cold water, and its installation time is shorter than copper.

The material boasts a lifespan of 30, 50 years and many manufacturers back it with a 25‑year warranty, matching Repipe OC’s own guarantee. Its flexibility means fewer joints, which reduces leak points.

Homeowners who want a low‑maintenance system often choose PEX because it handles temperature swings without cracking. It’s also approved by most plumbing codes for new construction.

One downside: PEX can’t be used outdoors where UV exposure is high, so exterior runs still need copper or another UV‑stable material.

3. Copper — Classic durability for premium installations

Copper has been the gold standard for plumbing for centuries. It handles hot water well and tolerates high pressure.

According to Wikipedia , copper pipes can last 50, 70 years when properly maintained. Repipe OC often pairs copper for visible runs, such as under sinks, where aesthetics matter.

The material’s antimicrobial properties keep water clean, and it works outdoors without UV concerns. It also meets all local code requirements for new homes.

The trade‑off is cost: copper is pricier than PEX and takes longer to install because each joint must be soldered.

 Best PEX Repipe Parts & Labor Warranty notes that many homeowners combine copper stub‑outs with PEX for interior runs, getting the best of both worlds.

4. PVC (Schedule 40) — Affordable, reliable drainage solution

PVC Schedule 40 is the go‑to material for waste and vent lines. It’s light, cheap, and easy to cut and glue.

Its lifespan ranges from 20 to 100 years, depending on installation quality. For new construction, PVC offers a quick way to meet code for soil and waste lines.

Because the pipe is rigid, it resists crushing under soil pressure, making it ideal for buried drainage. A limitation is that PVC can’t handle hot water above 140 °F, so it stays limited to drain and vent applications.

5. HDPE — Heavy‑duty buried mains for long‑term performance

High‑density polyethylene (HDPE) is used for underground mains and large‑diameter runs. It’s flexible enough to bend around obstacles yet strong enough to handle high pressure.

The material can last 50 years or more and is resistant to chemicals, making it a solid choice for new‑build foundations.

Installation uses fusion welding, which creates a smooth joint that won’t leak. This method also speeds up large‑scale projects.

HDPE isn’t suitable for interior finish lines because it’s harder to cut and connect in tight spaces. It shines in the buried portion of a plumbing system.

How to Choose Checklist

• Identify the main use: hot water, cold water, or drainage.

• Check local code requirements for the material.

• Match the lifespan to your ownership horizon.

• Balance upfront cost against long‑term maintenance.

• Prefer a provider that offers a transferable warranty.
