Decide whether repiping is the answer
Repiping is for failing pipe, not a single leak. A string of leaks, rusty water, falling pressure, or a pipe material known to fail are the usual triggers. If you are not sure, leak detection can show whether the problem is local or spread through the system.
Step by step through a repipe
Inspect and plan
The plumber identifies the pipe material, counts fixtures, and maps routes through the basement, attic, and walls.
Set the scope and permit
You agree on the scope, including which fixtures and valves are replaced, and the permit is arranged.
Open access points
Small holes are cut in drywall where lines must pass, usually near fixtures and in closets.
Run new pipe
New lines are pulled or run to each fixture, tied to the main shutoff and the water heater.
Test and patch
The system is pressure tested, and holes are patched ready for paint.
PEX versus copper
| Question | PEX | Copper |
|---|---|---|
| Speed of installation | Faster, fewer fittings | Slower, more soldering |
| Freeze tolerance | Better, it can expand slightly | Can split when frozen |
| Track record | Decades of use, newer than copper | Very long track record |
| Wall openings | Smaller, flexible pipe | Larger, rigid pipe |
| Material cost | Typically lower | Typically higher |
Both are code-approved for supply plumbing. PEX has become the common choice for whole-house repipes because it is quicker and needs fewer openings. Copper is still chosen for exposed runs and by owners who prefer it. Your plumber explains what fits your layout.

Living through a repipe
- Expect the water off for several hours each day for a few days.
- Plan for drywall dust and furniture moved from work areas.
- Ask about a temporary water source for the day, such as a hose bib line.
- Paint and wall finishing are usually a separate step from the plumbing.
- Keep pets and children away from open walls and tools.
For a short repair after a single leak, burst pipe repair may be enough. For a full system, the repiping page describes the service in more detail.
Questions to ask a plumber before a repipe
- What material do you recommend for my layout, and why?
- How many access holes do you expect and where?
- Will the water heater connections and shutoffs be replaced too?
- Who handles the permit and inspection?
- Is drywall patching included, and who paints?
- What does the written warranty cover?
Get the answers in writing. A repipe is a large project, and vague scope is the main cause of disputes. If two quotes differ widely, compare what each includes before comparing the totals.
Signs a repipe went well
Water pressure should be even at every fixture, with no noises in the walls when you turn a tap on or off. The water should run clear after the first flush. Walk through the house with the plumber and open every faucet before they leave, because a missed fixture is easy to fix on the day and harder a month later.
Who operates the street valve
According to the City of Forest Lake Water Department, the curb stop at the street is operated by city staff only. Do not count on it to stop water in an emergency, and close the main valve inside your home instead.
Forest Lake and lead service lines
The City of Forest Lake publishes a lead service line inventory. Its 2023 inventory lists 408 lead services, 46 galvanized services requiring replacement, and 3,895 non-lead lines, with no unknowns. The city points residents to the Lead Inventory Tracking Tool at the University of Minnesota to look up an address.
A repipe replaces the pipes inside your house, and the city is responsible for the water main and the line to the curb stop, while the part beyond is the customer's. If your service line is lead or galvanized, plan the replacement together with the interior work so the ground is opened once. Homeowners in Hugo and Wyoming should ask their own city for a service line inventory.
Questions Forest Lake Homeowners Ask
Usually not. A repipe covers the pipes inside the house. The service line from the street is a separate job, and in Forest Lake the city is responsible up to the curb stop.
The city publishes a lead service line inventory and points to the University of Minnesota Lead Inventory Tracking Tool. A plumber can also identify the material.
A typical house takes a few days. Larger homes or ones with difficult access take longer.
Most people stay home, but the water is off for part of each day. Plan around it.
Usually not for worn pipe. Damage from a sudden burst may be covered.
Often yes if the old pipe was corroded and restricted. New pipe of the right size restores full flow, though low pressure from the street would not change.
