SoCal Repipes Homeowner Guide
Whole House Repipe Checklist: What to Know Before Repiping Your Home
Planning a whole house repipe involves more than choosing new pipes. Homeowners should understand what is being replaced, which fixtures are included, whether PEX A or Copper Type L will be installed, where access openings may be needed, how the new piping will be routed, what restoration is included, and what should be checked before the project is considered complete.
Use this whole house repipe checklist before accepting a proposal.
A complete written repipe estimate should clearly identify the piping material, fixtures and appliances being connected, routing, access areas, pressure testing, permits when applicable, wall restoration responsibilities, exclusions, warranty information, and total project scope.
Before Getting a Quote
Information to Gather Before a Whole House Repipe Estimate
The more information available before the estimate, the easier it is to identify the appropriate repipe scope. A contractor should still inspect the property, but homeowners can prepare basic information about the plumbing system and problems they have experienced.
Written Repipe Proposal
What Should Be Included in a Whole House Repipe Quote?
A whole house repipe proposal should clearly explain what the contractor is installing and what the homeowner is purchasing. Avoid relying only on a total price without understanding the actual plumbing scope.
New Pipe Material
The proposal should identify whether the new water distribution system will use PEX A, Copper Type L, or another approved piping material.
Fixtures Included
The estimate should identify the plumbing fixtures, appliances and exterior connections receiving new hot or cold water lines.
Starting Point
Confirm where the repipe begins and whether the water service from the meter to the house is included or excluded.
Pipe Routing
Discuss whether new piping will be routed through walls, ceilings, attic areas, crawl spaces, garages or other accessible locations.
Testing
The new plumbing system should be tested after installation and connections should be checked before completion.
Restoration
The contract should clearly identify whether drywall patching, texture, primer, paint or other finish work is included.

Choosing Repipe Material
PEX A vs Copper Type L Before Repiping
SoCal Repipes offers both PEX A and Copper Type L whole house water repiping. Both can provide a reliable plumbing system when properly planned and installed. The better option depends on the home, accessibility, routing, exposure, budget and homeowner preference.
PEX A Repiping
PEX A is flexible cross-linked polyethylene water piping. Its flexibility can allow efficient routing through accessible walls, ceilings, attics and other areas while reducing the number of directional fittings required in certain layouts.
- Flexible water distribution piping
- Does not corrode like metal piping
- Efficient routing in many residential layouts
- Common option for complete whole house repiping
- Must be protected from unsuitable exposure
Copper Type L Repiping
Copper Type L is a rigid metal plumbing material selected by homeowners who prefer traditional copper water distribution piping.
- Rigid copper water piping
- Long-established plumbing material
- Often selected for certain exposed piping areas
- Directional changes generally require fittings
- Material and labor cost may be higher than PEX
| Comparison | PEX A | Copper Type L |
|---|---|---|
| Material | Flexible cross-linked polyethylene | Rigid copper tubing |
| Corrosion | Does not rust like metal piping | Water chemistry and conditions can affect copper over time |
| Routing | Flexible routing can reduce fittings | Directional changes normally require fittings |
| Installation | Efficient in many residential layouts | Installation can require additional labor depending on access |
| Cost | Often more cost-effective for a complete residential repipe | Material and installation costs are commonly higher |
Before Signing a Contract
Questions to Ask a Whole House Repipe Contractor
A homeowner should understand the entire project before work begins. These questions can help identify differences between repipe proposals that may look similar based only on price.
Access and Restoration
Ask What Happens to Walls and Ceilings During the Repipe
Whole house repiping generally requires access openings where new piping needs to pass through walls or ceilings and where fixture connections must be made.
A well-planned repipe uses accessible areas whenever practical, including attics, garages, crawl spaces, closets and ceilings, to reduce unnecessary openings.
Drywall Access
Confirm how many openings are expected and which areas of the property are most likely to require access.
Drywall Patching
Ask whether drywall patching is included and what level of restoration is provided.
Texture and Paint
Do not assume texture, primer or painting is included unless it is specifically stated in the written agreement.
Specialty Finishes
Tile, stone, cabinets, wallpaper, custom finishes and other materials may require separate restoration arrangements.
Compare the Complete Scope
Do Not Compare Repipe Prices Without Comparing What Is Included
Two whole house repipe estimates can have very different prices because they include different materials, fixture counts, restoration work or plumbing upgrades.
A lower estimate is not automatically a better value if important items are excluded.
Fixture Count
More bathrooms and plumbing fixtures require additional pipe, fittings and labor.
PEX or Copper
The selected material has a significant effect on project material and labor costs.
Home Layout
Property size, multiple floors, attics, crawl spaces and slab construction affect routing.
Wall Restoration
Drywall, texture, primer and painting can affect the final project cost.
Permits
Applicable permit and inspection requirements should be identified before work begins.
Additional Systems
Drain, sewer, gas, water main and remodeling work should not be confused with a standard water repipe.
Before Installation Day
How to Prepare Your House for Repiping
Preparing accessible plumbing areas before the crew arrives can make installation more efficient and reduce delays during the project.
Before the Project Is Complete
Whole House Repipe Final Inspection Checklist
After the new piping has been installed, the system should be tested and the included plumbing fixtures checked for proper operation.
Repair or Repipe?
Signs You Should Consider a Whole House Repipe
One isolated leak does not necessarily mean a house needs a complete repipe. A whole house repipe becomes more important to evaluate when the plumbing system is experiencing repeated failures.
Repeated Pinhole Leaks
Leaks appearing in different areas may indicate deterioration throughout the water piping system.
Recurring Slab Leaks
Multiple under-slab water leaks can make rerouting vulnerable piping worth evaluating.
Low Water Pressure
Restricted, deteriorated or improperly sized water lines can reduce usable water flow.
Discolored Water
Rust-colored or discolored water may be associated with aging metal piping.
Older Plumbing Materials
Galvanized steel, polybutylene and aging copper should be evaluated when problems become frequent.
Constant Pipe Repairs
Repeated repairs in different locations can make complete system replacement more practical.

Homeowner Questions
Whole House Repipe Checklist FAQs
What should I ask before getting a whole house repipe?
Ask which piping material will be used, which fixtures are included, where the new piping begins, how pipes will be routed, what wall access is required, whether permits and inspections are included, what restoration is provided and what warranty applies.
What should be included in a repipe estimate?
A written estimate should clearly identify the pipe material, plumbing fixtures being connected, routing, access requirements, testing, permits when applicable, restoration responsibilities, exclusions and project price.
Should I choose PEX A or copper for my repipe?
Both materials can be appropriate when correctly installed. PEX A provides flexible routing and corrosion resistance, while Copper Type L is a traditional rigid metal piping option. The appropriate choice depends on the property, routing, exposure, budget and homeowner preference.
Does a whole house repipe include drain pipes?
Not automatically. A standard whole house water repipe replaces pressurized hot and cold water piping. Drain, vent, sewer and gas piping are separate systems unless specifically included in the project.
Are walls opened during a whole house repipe?
Access openings are normally required where piping must be routed or connected. Accessible attics, garages, crawl spaces, closets and ceilings may be used when practical to reduce unnecessary openings.
How should I prepare my home before repiping?
Clear items from beneath sinks, provide access to closets, attic openings, crawl spaces and utility areas, protect valuables near planned access locations and confirm expected water shutoff periods before installation.
How long does a whole house repipe take?
Many residential water repipes can be completed in approximately one to two working days. Larger homes, difficult access, copper installation, permits, inspections or additional plumbing work can require more time.
What should I check after a whole house repipe?
Verify that the new system has been tested, included fixtures have proper hot and cold water service, connections are leak free, applicable inspections are complete and restoration included in the project has been finished.
