Hidden water and pipe trouble

Repiping and Whole-Home Pipe Replacement in Fountain Hills

Repiping swaps the supply pipes inside the house for new ones. Repiping becomes sensible once leaks keep turning up in new locations and patching each one no longer pays.

Ask for a written scope that shows where pipe will run and which walls will open.

Signs repiping is on the table

  • Repeat pinhole leaksA new leak appears each time the last one is fixed.
  • Discolored or flaky waterRust-brown or sandy water points to corroding pipe.
  • Low pressure everywhereMineral buildup narrows older pipe from the inside.

What repiping means

Repiping replaces the water supply lines that feed every sink, shower, toilet and appliance. It does not usually include the drain lines, which carry waste out of the house.

The new pipe is typically PEX or copper. PEX flexes around corners with fewer joints, whereas copper has decades of use behind it and tolerates heat well. Your contractor can explain which suits the house.

When to repipe instead of patching

One leak in a sound system is a patch. Several leaks in a few years, or a leak in pipe that looks pitted along its whole length, point to failure across the system.

Some homes built in the late 1970s through the mid 1990s used polybutylene supply pipe, which is known for failing at fittings. A plumber can check whether yours is a candidate.

Cost

What shapes a repipe quote

Whole-house pricing varies widely. These factors explain most of the differences between bids.

  • 1House size. A house with extra bathrooms and fixtures has more pipe and more joints to connect.
  • 2Pipe material. PEX and copper have different material costs and install methods.
  • 3Access. A single-story home with an attic is easier than a multilevel house with finished ceilings.
  • 4Wall repair. Drywall and paint can be included or left to you.

Compare bids by scope, not by total alone. A lower number that excludes patching may not be lower in the end.

In Fountain Hills

Older pipe and mineral-rich water

Fountain Hills was established in 1970, so many homes have pipe that has carried hard water for decades. EPCOR is the supplier, and a public summary of its data lists about 5.3 grains per gallon.

Minerals build up inside pipe and clog aerators and valves. A softener helps protect new plumbing, so ask about water treatment when planning a repipe.

How the work proceeds

Water is shut off, new pipe is routed through the attic or wall cavities and old lines are disconnected. Next the fixtures are reconnected, and the whole system gets a pressure test while the walls are still open.

Most repipes take a few days for a typical house, though the timeline depends on size and access. Plan for periods without water, and ask when each one will happen.

Walls, patching and living at home

Routing through the attic limits wall cuts, but some access holes are unavoidable. Agree in advance who patches and paints. Some contractors leave rough drywall repair to you.

Expect dust and noise. Cover furniture, clear closets that hold plumbing access and protect floors along the work path.

Alternatives to consider

Partial repiping replaces only the worst section, such as a slab-bound line. It costs less, though other sections of old pipe remain.

Coatings are sometimes offered for drain pipe, rarely for supply pipe. Ask what a method has done in homes like yours before agreeing to it.

Signs

Reasons homeowners look at repiping

A pattern of problems is the clue.

  • 1Repeated pinhole leaks. Several in a short span.
  • 2Rusty or brown water. Steel pipe corroding inside.
  • 3Low pressure everywhere. Scale narrowing old pipe.
  • 4Visible green corrosion on copper. Pipes thinning from the outside.
  • 5Brittle plastic that cracks. Aged fittings and pipe.

Repair, replace or repipe?

One leak is a repair. Two or three in a year suggest the system is wearing out. Cutting in new sections can work for a while, but each opening costs money and floor or wall repair.

A repipe replaces most of the supply pipe in one project. It ends the cycle and restores pressure, though it is the largest option. Compare it with a spot repair using the plumber's quote.

Galvanized steel and old polybutylene are common candidates. Ask what is in your house. A plumber can identify the material at an exposed section.

What the project involves

Crews cut small access holes in walls, run new pipe, test it and patch the openings. Water is off for a period during the work. Ask how long and whether a temporary supply is available.

Trenchless methods apply to the buried line, not the pipes in the walls. The water line page covers that option.

Cost depends on house size, access and pipe material, and a written quote should come before work.

Common questions

Repiping questions

The main warning signs are repeated pinhole leaks, discolored water, weak flow throughout the house and pipe types with a bad record, polybutylene among them. An inspection by a plumber will give you a professional opinion.

A typical house takes a few days, though size and access change the timeline. Ask for a schedule that shows when the water will be off.

Some openings are needed, but routing through the attic and closets limits them. Ask how many access holes to expect and who repairs them.

Both work well. PEX is flexible and quick to install, and copper is traditional and durable. Ask your contractor which they recommend for your house and why.

Planned repiping is scheduled ahead, but a failing line that is flooding the house is a night or weekend call. Close the main valve, then phone the line and say what happened.

Repeated leaks, rusty water and low pressure together point to it. One leak alone usually does not.

Duration varies with square footage and how easily the walls open. Request a schedule along with the quote.

Crews use small openings and patch them. The amount of patching depends on how the pipes run.

It is steel coated with zinc. The coating wears, the inside rusts and flow drops. Replacement is the usual fix.

Yes. A partial repipe, such as one bathroom branch, can make sense when only part of the system is failing.

Tired of fixing one leak after another?

Call and describe the history of leaks. The dispatcher can arrange a contractor who will look over the entire system.
