Signs the supply lines are near the end
One leak is a repair. A pattern of leaks is a message from the pipes. These are the signs plumbers look for before suggesting a repipe.
Repeated pinhole leaks
A second or third leak in a different spot suggests the whole run is thinning.
Low pressure at several fixtures
Mineral buildup inside old pipes narrows the opening, so flow drops everywhere.
Brown or rusty water
Corroding steel pipe sheds rust, especially after water sits overnight.
Blue-green stains on copper
Corrosion on the outside of a copper line shows the metal is breaking down.
Rising water bills
Hidden leaks under floors or in walls can run unnoticed for months.
A single hidden leak is a different problem, and our leak detection service finds it before anyone cuts into a wall.
Repair a leak or repipe the house
The right answer depends on how many leaks there have been and how old the pipe is. This table is a fair starting point.
| Situation | Repair the leak | Repipe |
|---|---|---|
| First leak in a newer system | Usually enough | Rarely needed. |
| Second or third pinhole leak | Buys some time | Worth pricing. |
| Low pressure at every fixture | Does not fix it | Often the cure. |
| Rusty water from the tap | Does not fix it | Often the cure. |
| Slab leak with failing pipe elsewhere | May be one of several | Reroute or replace. |
Dixon water, pipe material and permit rules
Source type: City of Dixon water quality report and permit handouts.The City of Dixon's 2024 water quality report lists total hardness averaging 163 parts per million, with pressure between 52 and 62 pounds per square inch. Hard water leaves scale inside pipes over the years, and constant pressure keeps a small defect leaking day and night.
The City of Dixon's permit handouts treat replacing a concealed pipe with new pipe as work that needs a permit, unlike a simple leak repair. For supply lines below a building, the handouts call for Type L copper, and copper under a slab must have no joints. Plastic is not allowed for water supply in that location.
For pipe inside walls and attics, the City of Dixon Building Division confirms which materials are accepted and whether an inspection is needed. A plumber who pulls the permit handles that contact for you.
A repipe follows the California Plumbing Code, which is based on the Uniform Plumbing Code (UPC). The City of Dixon's handout cites section 604.1 for supply pipe material, and the Building Division inspects the new lines.
What to do before the repipe crew arrives
A repipe goes faster and safer when the house is ready. Do these things the day before.
- Clear the paths to closets, the attic hatch and the water heater.
- Move furniture and valuables away from walls that may be opened.
- Cover floors and belongings, since drywall dust travels.
- Plan for water to be off for part of each day.
- Keep children and pets out of the work area.
- Do not run water or appliances while the crew has lines open.
Pinhole leaks again?
Describe where the leaks have been and how old the house is. A same-day appointment is offered when available.
How a repipe is done
A repipe starts with a walkthrough. The plumber locates the main shutoff, counts fixtures and decides where new lines can run with the least wall damage. In many homes, access holes are cut at the ceiling or in closets, and the lines are routed through attics and crawlspaces.
Water is shut off while the new lines are installed and connected, then tested under pressure. Drywall repair is a separate trade, so ask what is included in the quote. A partial repipe replaces only the failing run, such as the kitchen and bathroom branch lines, and can be a good middle path.
What to ask before approving a repipe
A repipe is a large job, so the quote should answer a few questions in writing.
- Which pipe material will be used and why.
- Whether the quote includes the permit and inspection.
- How many access holes are expected and who repairs them.
- How long the water will be off each day.
- What warranty applies to the work.
California law requires a contractor license for work of $1,000 or more in labor and materials. You can check a license at cslb.ca.gov or by calling 800-321-2752.
What changes the price of repiping
Repipe prices vary a lot between homes. The plumber walks the house before giving a number.
Insurance rarely pays to repipe an aging system, but it may cover water damage from a sudden burst. Ask your agent before work starts and keep photos.
For your real number, call (916) 312-0578 and tell the dispatcher the age of the house and how many leaks there have been.

We quote repipes across Dixon and in Vacaville and Davis. If a failed line is flooding a room right now, burst pipe repair is the faster path, and a repipe can follow once the water is under control.
Repiping questions from Dixon homeowners
Count the leaks and check the pressure. A single leak in an otherwise healthy system is a repair. Several pinholes, low pressure and rusty water point to the whole system aging.
The City of Dixon's handouts list replacing a concealed pipe with new pipe as work that needs a permit. Your plumber can pull it and schedule the inspection.
Often yes, but water is off for part of each day. Ask for a schedule so you can plan around it.
If the cause is scale or corrosion inside the old lines, yes. If the cause is a failing pressure regulator or a partly closed valve, a cheaper repair may solve it.
