How do repipe plumbers plan a whole-house job in Redmond?
Good repipe plumbers plan the route before they open a single wall. The goal is to run new lines through attics, crawlspaces and closets, so the house needs as few openings as possible.
A typical planning visit covers:
Every fixture, from sinks and showers to hose bibs and the fridge line
The water service coming in from the meter, plus any pressure reducing valve
Access routes through the attic, crawlspace or basement
Problem spots, such as past leaks, pinholes or low-pressure rooms
Redmond's housing stock shapes what we find. Many neighborhoods grew quickly in the 1970s through the 1990s, so pipe problems tend to follow the build era:
Home built | Pipe we often find | Common problem |
Before 1970 | Galvanized steel or early copper | Rust, low pressure, brown water |
Late 1970s to mid-1990s | Polybutylene (gray plastic) | Fittings crack without warning |
1970s to 2000s | Copper | Pinhole leaks, often on hot lines |
Any age | Mixed patches of old and new | Leaks where materials meet |
If your home still has galvanized lines, our guide to galvanized pipe replacement explains why patching rarely lasts.
What does a whole house repipe company replace?
A whole house repipe company replaces every water supply line in the home, from the main shutoff to each fixture. Drain lines are a separate system and usually aren't part of a standard repipe.
Here's what's normally included:
The main line from where water enters the house
All hot and cold supply lines to every fixture
New shutoff valves at sinks and toilets
Water heater connections, hot and cold
Outdoor hose bibs and the fridge or ice maker line
Pressure testing before any wall gets closed
Optional add-ons often make sense at the same time. For example, a new pressure reducing valve protects the new pipe if your street pressure runs high. Likewise, an aging water heater is easier to swap while crews are already on site.
Why do PEX repipe contractors prefer PEX for most Redmond homes?
PEX repipe contractors use PEX because it's flexible, needs fewer fittings and snakes through walls with smaller openings. That usually means a faster job and less drywall repair.
There are different types of PEX, though. People often ask what is the difference between PEX-A and PEX-B. Here's the short version:
Feature | PEX-A | PEX-B |
Flexibility | Most flexible | Stiffer |
Kinks | Can often be repaired with heat | Usually need a fitting to repair |
Typical fittings | Expansion fittings | Crimp or clamp fittings |
Cost | Higher | Lower |
Freeze tolerance | Very good | Good |
Layout matters too. Homeowners also ask what is a home-run PEX manifold system. Instead of one main line branching off to each fixture, a manifold sends a separate line to each fixture from a central hub. As a result, pressure stays steadier when two showers run at once. It also lets you shut off a single fixture from one spot.
Copper still has a place. We use it where pipes are exposed, near water heaters, or where a homeowner simply prefers it.
When does a Redmond repipe need a permit?
A whole-house repipe in Redmond needs a plumbing permit and inspections before the walls are closed. People often ask do you need a permit to repipe a house in Redmond. Yes, because replacing a home's water supply system is plumbing work the city reviews.
The City of Redmond lets contractors apply for residential plumbing permits online through its ePermitting service. Here's how it typically fits into a job:
Permit filed before work starts
Rough-in inspection once new pipe is installed and pressure tested
Walls patched after the inspection passes
Final inspection to close the permit
Skipping the permit can cause problems when you sell the house. So it's worth confirming that your contractor pulls one.

Frequently asked questions
1. What makes a repipe specialist different from a general plumber?
A repipe specialist focuses on repiping jobs exclusively while a general plumber handles a wider variety of repairs and installations. Both trades require certification through the state of Washington, but a specialist should be able to complete repipes faster and anticipate potential problems during the job. A qualified specialist will also do their own permitting work for your protection.
2. What should a repipe quote include before you sign?
Your quote should include the fixtures being repiped, the type of materials used in the installation and whether the cost includes the main water line. Your contract should also specify if the job allows for permits, inspections, drywall patching and a warranty. If painting, water heater servicing and pressure valve adjustments are required in addition to repiping, these should be detailed separately in your contract.
3. How long does a whole house repipe take in a Redmond home?
Most whole house repipes in Redmond take between 2-5 working days to complete. Jobs can take longer because of patching and inspection delays. Repiping homes with crawlspaces and unfinished attics tend to be quicker than slab or finished basement homes.
4. Do the walls have to be opened, and who patches them afterwards?
Some smaller openings are required for fixtures, but a professional company will take care to route the pipes through your attic or crawlspace wherever possible to avoid excessive openings and patching. Patching should be specified in your contract and included in your job description as a complete repiping job, including drywall patching.
5. What warranty should come with a repipe?
Always ask for a written warranty on workmanship from the company performing your repipe and a separate warranty from the manufacturer on the materials used. Many PEX manufacturers offer impressive warranties when their pipes are installed by an approved contractor. Be sure to ask if the warranty covers replacement costs in the event you sell your home and transfer the coverage to the new owner.
6. Can we stay in the house during a repipe?
In most cases, yes. The water is shut off for several hours during the day while the repiping is done, but it is typically turned back on in the evening so that water is available during the night. We will always provide you with specifics for your home.
7. Is polybutylene pipe a reason to repipe?
Polybutylene is one of the leading reasons homeowners turn to repiping services. These pipes have a tendency to crack at the fittings without warning. Polybutylene is considered to be a hazardous material by some insurance companies and can lower the resale value of your home. It is usually less expensive to replace polybutylene pipes before a rupture occurs.
8. Will a repipe improve my water pressure?
If you're experiencing low water pressure, a repipe will most likely correct this issue. Older galvanized water pipes tend to restrict water flow as they age. Newer copper or PEX pipes will provide maximum flow with little or no pressure loss. Water pressure issues can also be caused by the pressure reducing valve or your city water supply, so we'll check those as well.
