What is the difference between plumbing and repiping?

Plumbing is the overall term for a building's water supply, drain, and gas systems, while repiping specifically means replacing all or most of the existing water supply pipes, usually because of corrosion, leaks, or outdated materials like galvanized steel or polybutylene. Repiping is one specific plumbing project among many. Arrow Plumbing performs full repiping projects for homes throughout the Houston, Texas area.

Is repiping a house worth it in Houston, TX?

Repiping is often worth it for homes with recurring leaks, low water pressure, or rusty water caused by aging galvanized or polybutylene pipes, since it addresses the root cause instead of patching one leak after another. Homes showing these signs across multiple fixtures rather than in just one spot are the strongest candidates. Arrow Plumbing evaluates whether a repair or full repipe makes more sense for homeowners in Houston, Texas.

How is repiping done?

Repiping involves removing old water supply lines and installing new pipe, usually copper or PEX, routed through walls, floors, or attics with minimal drywall cutting when possible, then reconnecting all fixtures and testing for leaks before closing up access points. The job is typically completed in stages to keep some water running each day. Arrow Plumbing repipes homes throughout the Houston, Texas area using this process.

What pipe materials are typically used for a home repipe?

Copper and PEX are the two most common materials used for a home repipe, with copper offering long-term durability and PEX offering flexibility that makes it faster to install through tight spaces and less prone to bursting in freezing conditions. The right choice often depends on the home's layout, budget, and local code preferences. Arrow Plumbing recommends the pipe material best suited to each home during a repiping project in Houston, Texas.

Does repiping lower insurance in Harris County?

Repiping can sometimes lower homeowners insurance premiums because insurers view homes with new copper or PEX pipe as a lower risk for water damage claims than homes with old galvanized or polybutylene pipe, though the discount and eligibility depend on the insurance carrier. Homeowners should check with their insurer directly. Arrow Plumbing provides repiping documentation homeowners can share with insurers in Harris County, Texas.

How long should a repipe take?

A whole-house repipe typically takes 2 to 5 days depending on the home's size, number of bathrooms, and whether walls need to be opened for pipe access, with water shut off for only part of each day. Larger or multi-story homes take longer. Arrow Plumbing schedules repiping projects to minimize disruption for homeowners in the Houston, Texas area.

How much wall or ceiling damage does a repipe typically cause?

A repipe typically requires some access points cut into walls or ceilings to reach existing pipe runs, though experienced plumbers plan the route to minimize the number and size of these openings whenever possible. Homes with an accessible attic or crawl space usually need less wall cutting than homes without one. Arrow Plumbing plans repiping routes to limit drywall damage for homeowners throughout Houston, Texas.

How does a homeowner know if a repipe is needed instead of individual pipe repairs?

A repipe is typically the better option once a home has experienced leaks in multiple locations, shows discolored water throughout the house rather than at just one fixture, or has pipe made of an outdated material like galvanized steel or polybutylene that is known to fail broadly over time. A single isolated leak in an otherwise sound system usually just needs a spot repair instead. Arrow Plumbing assesses whole-home pipe condition to determine whether a repipe is the right call for homeowners in Houston, Texas.

How to Tell Your Home’s Pipes Are Past Saving

A few clear signs tend to show up when a home’s plumbing has reached the end of its useful life. Discolored or rusty water, especially right after the water’s been off for a while, often points to corroding galvanized pipe. Frequent pinhole leaks in different locations suggest the pipe material itself is failing rather than one isolated bad section. Noticeably reduced water pressure throughout the house, not just at one fixture, can mean mineral buildup has narrowed pipes across the entire system. When repairs start happening every few months instead of every few years, that pattern alone is usually a sign that patching individual leaks no longer makes financial sense.

We’ve talked with homeowners who spent thousands of dollars over a year or two chasing individual pipe leaks throughout an older home, only to end up needing a full repipe anyway once the pattern became clear. Recognizing that pattern earlier, rather than treating each leak as an isolated incident, often saves money in the long run and avoids the water damage that can come from a leak going undetected inside a wall.

Galvanized and Polybutylene: The Two Pipe Types We Replace Most

Two pipe materials account for the vast majority of the repiping work we do. Galvanized steel pipe, common in homes built before the 1960s, corrodes from the inside out over decades, gradually narrowing the interior diameter and eventually developing leaks as rust eats through the pipe wall. Polybutylene, used in home construction primarily during the 1980s and early 1990s, has a well-documented tendency to become brittle and fail, particularly at fittings, often without much warning. Homeowners with either material in their home are generally better served planning a proactive repipe rather than waiting for a failure that could cause significant water damage.
