When repiping beats another repair
Repiping is replacing all or most of a home's water supply lines with new pipe. It is the answer when the pipe itself is the problem, so fixing one leak just moves the next leak somewhere else.
The usual signs are a pattern rather than a single event: several slab leaks, pinholes in copper in different rooms, or original polybutylene pipe that insurers and inspectors flag.
A repipe is a big project, but it is finished in days in most homes. New lines are run through walls and ceilings rather than under the slab, which also removes the risk of future slab leaks in the old lines.
Repipes in Surprise are permitted through the City of Surprise, and many requests come from the older parts of town near Bell Road and Kingswood Parke. Across Maricopa County, homes of that age are reaching the point where lines fail in more than one spot.
Signs your home may need a repipe
One of these alone may not be enough. Two or more usually is.
| Sign | What it suggests |
|---|---|
| More than one slab leak. | Buried lines are wearing out along their length. |
| Pinhole leaks in different rooms. | Copper is corroding throughout the system. |
| Gray polybutylene pipe | A material known for failing with age. |
| Rusty or discolored water | Corroding galvanized pipe in older homes. |
| Low pressure throughout the house. | Scale or corrosion narrowing old pipe. |
PEX or copper?
Both are approved materials under the IPC. Each has trade-offs.
Cross-linked polyethylene
PEX is flexible, so it can be routed through walls and ceilings with fewer fittings and less drywall opened. It resists scale and handles expansion well.
It must be kept out of direct sunlight, which matters for any line in an exposed location.
Good fit when
Most whole-home repipes
Usually faster to install and lower in cost.
Type L or M copper
Copper is durable and long-proven, and some owners prefer it. It costs more in material and labor.
In aggressive water it can develop pinholes over time, so water chemistry is part of the decision.
Good fit when
Owner preference or matching existing lines
Heavier and slower to install than PEX.
What to do to get ready for a repipe
Preparation shortens the job and protects your home.
- Clear access to walls. Move furniture and wall hangings where lines will be run.
- Plan for water outages. Water is off for parts of the job. Ask for the schedule.
- Ask about patching. Confirm whether drywall patching and paint are included.
- Confirm the permit. A whole-home repipe generally needs a city permit and inspection.
- Protect valuables. Cover furniture and electronics in rooms where drywall will be opened.
What changes the cost of a repipe
Repipes are quoted free after a walkthrough of the house.
| Cost factor | How it moves the price |
|---|---|
| Size of the home | More bathrooms and fixtures mean more pipe and labor. |
| Material | Copper costs more than PEX in both material and labor. |
| Routing | Single-story homes with attic access are usually simpler to route. |
| Drywall repair | Patching and paint add to the total if included. |
| Permits | A city permit and inspection add fees and time. |
Insurance and repiping
Insurance rarely pays for repiping, since it is considered an upgrade. Some insurers require replacing polybutylene before writing a policy.

Repiping questions we hear

No. Repiping routes new lines through walls and ceilings, so the old under-slab lines are abandoned in place.
