Repiping means replacing the supply lines that carry water through your walls, floors and ceilings. Most Eden Prairie homeowners start asking about it after a second or third leak in the same house, when patching stops making sense. This page walks through the signs, the materials, the trade-offs between a whole-house and a partial job, and what the work involves. Our 24/7 dispatch line is there if a pipe fails before the project is scheduled.
Signs your supply pipes are due
A single leak does not mean new pipe. A pattern does. Look for pinhole leaks that keep reappearing on different runs, water that comes out brown or orange after sitting, pressure that is weak at every fixture, and visible green or white crust on pipe joints.
Signs a repipe is worth pricing
Repeat pinhole leaks
Two or more leaks on separate runs in a short time suggest the pipe wall is thinning everywhere.
Discolored water
Rusty or brown water at the tap, especially the first draw in the morning, can point to corroding steel pipe.
Low pressure throughout
Every fixture runs weak, which can mean mineral buildup inside the pipe.
Old galvanized pipe
Gray steel pipe with threaded joints is at the end of its life.
Polybutylene pipe
Gray or blue flexible plastic installed in some homes from the late 1970s through the mid-1990s has a poor record.
What Eden Prairie homes tend to have
The City says most Eden Prairie homes date from the 1970s onward, with a few older farm-era buildings. So galvanized steel is rare here except in older buildings, and many houses carry copper from that era or PEX from a later remodel. The bigger local question is polybutylene, since some homes from the late 1970s through the mid-1990s were piped with it.
Older buildings can still carry old runs. The Eden Prairie Historical Society says the brick Cummins-Phipps-Grill House, built in 1879 to 1880, did not get its first bathroom until 1946, which is a reminder that an old building can hold several generations of plumbing in one wall. If your home is older, expect mixed materials and plan for surprises.
Choosing a pipe material
| Material | Strengths | Trade-offs |
|---|---|---|
| PEX | Flexible, fewer fittings, quieter, easier to route through finished walls | Not for outdoor sun exposure and needs correct fittings |
| Copper | Long record, rigid, handles heat well | Labor-heavy, can pit in aggressive water and costs more in materials |
| CPVC | Rigid plastic, cheap, simple joining | More brittle with age and heat, less common for new work |
No material is perfect. PEX is the most common choice for repipes because it threads through walls with fewer cuts. Copper is a fair choice when you want metal throughout, and CPVC is mostly seen in budget projects. We talk through your house, your access and your preferences before choosing.
Lead and water quality
Homeowners sometimes ask if repiping will fix lead. The City says no homes in Eden Prairie have tested positive for lead or copper in drinking water (0 of 30 tested sites over the action levels in its 2020 report).
It adds that lead usually enters water inside the home through lead solder or brass fixtures, and that most homes were built after code safeguards were in place. If you are worried, test your tap and ask the City for its water quality report before spending on pipe.
Talk to a dispatcher about repiping
Dispatch answers 24/7 and books same-day appointments when one is open.
Whole-house or partial repipe
A whole-house repipe replaces every hot and cold supply line from the main to each fixture. It makes sense when failures are spread across the house, when the pipe is a known problem type, or when walls are open for a remodel. A partial repipe replaces one branch, such as the kitchen and half bath, and fits when the damage is limited and the rest of the pipe is sound.
The honest trade-off is access. A partial job is smaller and cheaper now, but it can leave older pipe in the walls to fail later. When one branch has failed twice, ask for a pressure test on the rest before deciding. Leak detection can map which lines are leaking before you commit.
Access, drywall and the water-off schedule
Most repipes open small access holes at each fixture and along the run, not whole walls. We run new lines through the same chases where possible, and patching is usually limited to drywall holes. Painting and finish work are other trades.
Water is off while lines are cut and joined, and a whole-house job normally means the water is off for part of each work day, with a plan to restore it in the evening. We tell you the plan before starting, so you can fill containers and schedule showers.
Permits and inspections
Whether a given repipe needs a permit varies, and the rules are set by the City and the Minnesota Plumbing Code (Minnesota Rules chapter 4714). The City's Building Inspections Division issues the Sewer and Water Permit, and the form lists inspections such as rough-in, final, meter and air test. Ask the Eden Prairie building department what applies to your job.
What drives the cost of repiping
Cost depends on house size, how many fixtures sit on the lines and how much wall has to be opened. We give you a clear price before work starts.
Homeowner insurance often covers sudden burst or accidental discharge but usually not gradual leaks or wear, and a repipe done only because pipe is old is generally not covered. Ask your insurer before the work starts. Want your real number for your house? Call (952) 866-9120 and we will quote the job before work starts.
We repipe homes across Eden Prairie, including the 55344, 55346 and 55347 ZIP codes, and nearby Hopkins addresses. If a pipe has already split, start with burst pipe repair. For pressure from the street side, see water line repair, and for added fixtures plumbing installation covers the connections.
New supply piping must meet the Minnesota Plumbing Code, Minnesota Rules chapter 4714, which sets the state standards for approved pipe materials and installation.
Repiping questions in Eden Prairie
A single leak in sound pipe is a repair. Repeat leaks on different runs, discolored water or pipe known to fail, such as polybutylene, point toward replacement. A pressure test of the rest of the system helps you decide.
The City says most homes date from the 1970s onward, so galvanized is rare except in older buildings. If your house is old, check any gray threaded steel you can see near the water heater.
PEX is easier to route and has fewer joints, while copper is rigid and has a long record. The best choice depends on your walls, your budget and your preference.
The City reports no tested sites above lead or copper action levels, and says lead usually comes from solder or brass fixtures inside the home. A repipe replaces the pipe and solder, but test your tap first.
It depends on house size and access, but water is typically off for part of each work day. We plan the schedule with you ahead of time.
It varies by job. Ask the Eden Prairie building department, which issues the Sewer and Water Permit and sets inspections.
What to check before you call
Walk through the house and note every leak, stain and weak fixture. Find the water heater and meter and look at the pipe type near them. Photograph any gray or blue flexible pipe, take note of your home's age and list which rooms you plan to remodel.
