Signs You Need to Repipe

Discolored water at multiple faucets, frequent pinhole leaks, visible corrosion on exposed pipes, and noticeably low water pressure are strong indicators that repiping is overdue.

The Repiping Process

A crew maps existing plumbing, opens access points in walls and ceilings, runs new PEX or copper to every fixture, connects everything, pressure-tests the system, and patches wall openings.

PEX Manifold vs. Trunk-and-Branch

Manifold (home-run) systems use individual lines from a central manifold to each fixture—better pressure balance but more tubing. Trunk-and-branch uses shared main lines with tees.

Frequently Asked Questions

When is repiping necessary?

Repipe if you have galvanized, polybutylene, or lead pipes, or if you experience frequent leaks, low pressure, and rusty water throughout the house.

PEX or copper?

PEX is 40-60% cheaper, faster to install, and resistant to freezing. Copper lasts longer and has a proven 50+ year track record.

How much wall damage should I expect?

Plumbers make small access holes at fixture locations and along pipe routes. Patching and painting are usually included or quoted separately.

Can I stay in the house during repiping?

Usually yes. Water is typically off during work hours (8-10 hours/day) but restored each evening.

Does repiping increase home value?

Yes. New plumbing eliminates a major concern for buyers and can add $5,000-$15,000 in perceived value.
