Partial vs Full Repipe: Which Is Right for Your Home?

When plumbing issues arise, homeowners often ask:

Can I just replace part of the system instead of the whole thing?

The answer depends on the condition of your pipes.

What Is a Partial Repipe?

A partial repipe replaces only sections of piping that have failed or are accessible.

This may include:

One bathroom branch
A kitchen line
A localized leak repair section

Partial repipes are typically appropriate when:

The plumbing system is relatively new
Corrosion is isolated
Failure is limited to one area

A full repipe replaces all hot and cold water supply lines throughout the home.

This is usually recommended when:

Galvanized pipes are original and over 40 years old
Multiple leaks have occurred
Pressure is declining system-wide
Corrosion is widespread

If your home shows multiple warning signs, review:
How Do I Know If My House Needs Repiping?

If you are fixing new leaks every year, partial replacement may simply delay full replacement.

Repeated spot repairs can:

Increase long-term cost
Create inconsistent pipe materials
Extend disruption over multiple years

Partial Repipe
Lower upfront cost
Potential for future failures

Full Repipe
Higher initial investment
Long-term reliability
System-wide reset
