Repiping & Whole-Home Pipe Replacement in Meridian, ID
Repiping means replacing the water supply pipes inside your home, the lines that carry water from where it enters the house to each faucet, toilet, and appliance. It is different from water line repair, which deals with the buried service line from the meter.
A repipe is a planned project, not an emergency. We offer free estimates and walk through your home's pipe material and condition before recommending anything.
My water is rusty and the pressure keeps dropping. Is it my pipes?
Often it is. Galvanized steel pipe rusts from the inside, and the buildup narrows the pipe until only a trickle gets through. Rust flakes also break loose and tint the water, especially after the water has sat overnight.
Repeated pinhole leaks in copper pipe tell a similar story. When the pipe is failing in several places, fixing leaks one at a time costs more over a few years than replacing the system once.
Galvanized supply lines are most common in the 1950s to 1970s homes of Garden City, where repipes are a regular recommendation.
Galvanized service lines often fail at the same time as the pipes inside, so it is worth having the water line from the meter checked during a repipe estimate.
Galvanized pipe is most common in Ada County's older neighborhoods, such as Old Town Meridian near Main Street.
Pipe materials and what they mean for your home
The age of a Meridian home is a strong clue to what is inside its walls.
| Material | Common era | Outlook |
|---|---|---|
| Galvanized steel | Homes built before about 1970, mostly Old Town | Near end of life, restricts flow, rusts. |
| Polybutylene (gray plastic) | Late 1970s to mid-1990s | Known to fail at fittings, often replaced proactively. |
| Copper | 1970s through 1990s and later | Long-lived, can develop pinholes with age. |
| CPVC | 1990s and 2000s | Can turn brittle with age and heat. |
| PEX | Mid-1990s to today | Current standard, flexible and freeze tolerant. |
General patterns by era. Your home's piping is confirmed on site.
If you see gray plastic pipe stamped PB near your water heater or under sinks, that is polybutylene. It deserves a professional look even if it is not leaking yet.
Signs it is time to repipe
One of these alone may be fixable. Several together usually mean repiping is the better investment.
- Low pressure at several fixtures, not just one.
- Brown or rusty water, especially first thing in the morning.
- Two or more pinhole leaks in the past couple of years.
- Galvanized or polybutylene pipe anywhere in the home.
- Corroded or crusted fittings visible under sinks or in the crawl space.
If the problem might be one leak rather than the whole system, our leak detection service can confirm it before you commit to a repipe.
PEX or copper for a Meridian repipe
Most repipes today use PEX. It bends around framing, needs fewer fittings, and handles freezing better than rigid pipe, which matters in homes with plumbing running through crawl spaces. It also costs less to install than copper.
Copper remains a solid choice and some homeowners prefer it. It is more expensive and takes longer to install. Both are allowed under the Idaho State Plumbing Code, which builds on the Uniform Plumbing Code (UPC).
Whichever you choose, the new system should include accessible shutoff valves at each fixture and a main shutoff that is easy to reach, since the crawl space is where many Meridian mains are located.
How a repipe gets done
In a home over a crawl space, much of the new piping can run underneath, with short runs up into walls at each fixture. That keeps drywall openings small. Homes on a slab or with plumbing in upstairs walls may need more access holes.
Most single-family repipes take a few days. Water is usually restored each evening so the house stays livable. After the new system is pressure tested and inspected, wall openings are patched.
Repiping is permitted work. Inside Meridian city limits, the permit and inspection run through Meridian Building Services.
What determines the cost of repiping
Repiping costs vary mainly with the size of the house and access to the pipes.
- Number of bathrooms, fixtures, and total pipe length.
- PEX or copper.
- Crawl space access versus slab or finished walls.
- Drywall patching and finish work included in the scope.
- Permit and inspection.

Repiping questions
How long does it take to repipe a house?
Most single-family homes take a few days. Water is usually back on each evening.
Will you have to tear out all my walls?
No. In crawl space homes much of the piping runs underneath. Openings are kept small and patched afterward.
Is PEX safe for drinking water?
Yes. PEX is approved for potable water under the plumbing code and is the most common repipe material today.
Do I need to repipe if I have polybutylene?
It is not required, but polybutylene has a history of failing at fittings. Many owners replace it before it leaks.
Is repiping the same as replacing the water line?
No. Repiping replaces pipes inside the house. The water service line runs underground from the meter to the house.
Do you offer free estimates for repiping?
Yes. Repiping is planned work, and estimates are free.
