    Repiping Guide

    Water Service Line vs. Indoor Repiping

    The pipe that brings water to your home and the pipes that distribute it inside are two different systems. Knowing where one ends and the other begins clarifies scope and responsibility.

    A water service line runs from the meter to the home; indoor repiping replaces distribution piping inside. They're separate scopes with different boundaries — and responsibility for the service line can vary.

    The Water Service Line

    The water service line is the pipe that runs from the utility meter to where water enters your home. It's underground and outside the living space. Replacing it involves excavation from the meter to the entry point.

    Responsibility for this line often splits at the meter, but the exact boundary can vary by locality. Confirm the boundary for your property before assuming which portion is yours to address.

    Indoor Repiping

    Indoor repiping replaces the piping that distributes water inside the home — the lines that run to fixtures, bathrooms, and appliances. This work is inside the living space and involves wall, ceiling, or floor access.

    Because it's a different system with different access, indoor repiping is a separate scope from the service line, even if both need attention.

    Why the Distinction Matters

    • Different access: underground vs inside the home
    • Different responsibility boundaries for the service line
    • Separate scopes, even if both need work
    • Confirm the meter boundary for your property

    Unsure Which Scope You Need?

    An assessment can clarify whether the issue is the service line, indoor piping, or both — and where the boundaries fall.
