Polybutylene Pipe Replacement in Phoenix
If a home inspector flagged gray plastic pipe, you found “PB2110” printed on a line under a sink, or your house was built between 1978 and the mid-1990s and has leaked more than once, you're on the right page. Polybutylene was used in millions of homes in the U.S. and Canada in those years, and it is no longer accepted by U.S. plumbing codes.
Replacing it is a repipe, and repipes at American Discount Plumbing are done in PEX and backed by a two-year workmanship warranty. Before anything is priced, Pavel Farcas (Paul) checks the pipe. Some gray plastic is PEX, and nobody should pay to replace pipe that is already fine.

“The inspector wrote 'polybutylene' on our report.”
A line item on a sale: the paperwork that starts the clock.
Buyers and sellers both notice that line. InterNACHI, the home inspectors' association, warns that owners of homes with PB might face higher premiums or be denied coverage, and that PB can lower a home's value or keep it on the market longer. Its advice is to replace PB before it fails. The next step is a price for the replacement.
“We've had two leaks in a year, both at fittings.”
Failures at the joints are the pattern this pipe is known for.
The chlorine and chloramine that disinfect city water can break polybutylene and its plastic fittings down over time, and the damage shows first where the pipe is under stress: fittings, sharp bends and kinks.
“I think we have it. How would I know what I am looking at?”
Color and flex narrow it down, and the pipe's printing settles it.
PB is most often gray, sometimes white, silver, black, or blue, and it bends where copper would not. Look at the water heater, under the sinks, and at the main shutoff where the line enters the house. Near fittings and bends, white patches on the plastic are worth noting: that stress whitening generally comes before the material breaks down.
What Polybutylene Replacement Includes
Walls, drywall and older homes
Running new pipe means opening walls and ceilings in places. Drywall repair and paint are not part of our work; we refer you to a drywall contractor you hire directly. In homes built before 1978, we only take on work that leaves painted surfaces undisturbed. If a repair would need a painted wall opened, that part goes to a lead-safe certified contractor you hire directly; we do not perform or arrange it.
What new pipe leaves alone
New pipe does nothing for hard water. The scale on faucets and in water heaters comes from the water itself, and treatment is a separate job on our water treatment page. It also leaves the drains alone: polybutylene was a supply-pipe material, and the drain lines are a separate system.
From the First Look to New Pipe
Read the pipe
We read the markings and fittings at the heater, the sinks, and the main shutoff, then say whether it is polybutylene or something else. If those spots disagree, we keep looking until the picture is clear.
Map the new lines and price them
The fixtures, the routes, and the openings needed all go on the quote.
Replace and switch over
The new lines go in, the water goes back on, and the old lines are taken out of service.

What Polybutylene Replacement Costs in Phoenix
Every fixture the new pipe has to reach adds to the job, so a larger house with more bathrooms takes more pipe and more time. Long runs through an attic or down a long hallway add length, and a compact single-story plan takes less. The quote is written up once we have walked the house. If a visit ends with nothing done, the service fee is $75; go ahead with the repipe, and it does not apply.
On a repipe, veterans and owners aged 55 or more save 15%, and seniors, first responders and those in the military save 10%.
The settlement is closed
A national class-action settlement, Cox v. Shell Oil, once paid for PB leaks and replacements. The court approved it in November 1995 with an initial commitment of 950 million dollars. Its claim filing deadline expired in 2009, so today the cost of replacing polybutylene falls to the owner.
Two Things That Make PB Hard to Spot
Earlier owners fixed part of it
A leaking run or a bathroom was replaced years ago, so some lines are PEX or copper and the rest are still polybutylene.
We map which is which, so the quote covers only what still needs replacing. Receipts from earlier repairs, if you have them, help fill in that map.
New pipe at the heater, old pipe everywhere else
A water heater swap left fresh connections at the tank, so the one spot most people look at is not polybutylene.
The lines under the sinks and at the main shutoff tell the real story, and that is where the old pipe usually hides.

Polybutylene and Phoenix Homes: What Applies Here
Selling a home in Arizona
On the Arizona REALTORS disclosure form, sellers are asked whether they know what their water pipes are made of, and polybutylene is one of the materials it lists. The same form has a question on past or present plumbing problems. Knowing what you have before you list keeps that answer simple, and a buyer's inspector reads the same markings anyway. If the pipe has already been replaced, keep the invoice with your home records, because it answers the question with paperwork.
The line from the meter
Inspectors find PB at the water meter and the main shutoff as well as inside. In Phoenix, the buried line from the meter to the house is the owner's, so if it is PB, the cost of replacing it is too.
If a PB line bursts before it is replaced
Stop the water at the house valve first; our main shutoff page shows where it usually sits and what to do if it refuses to turn. Then call us.
Three Decisions Before You Replace PB
01 When to replace it
Waiting keeps the money in your pocket until the next failure. The catch is that a leak while you are away can run for hours before anyone sees it, and a leak inside a wall or ceiling brings its own repair bill. If you travel for weeks at a time, that risk carries more weight.
02 What your insurer says about it
Ask your carrier two questions before you set a date. The first is whether the policy would pay anything toward replacing the pipe, and only your insurer can answer that, because policies differ. The second is what keeping the pipe costs you in the meantime: InterNACHI, the home inspectors' association, warns that owners of homes with polybutylene might face higher premiums or be denied coverage altogether. Get both answers before you decide on timing, because together they tend to settle it more firmly than the plumbing does.
03 The yard line
If the line from the meter is also PB, replacing it at the same time closes out the material entirely; our main water line page covers that job. If it is another material in good shape, it can stay. Either way, ask for the yard line as its own line item so you can decide on it separately.
Polybutylene Pipe FAQs
Still have a question? Call Pavel (Paul) directly and get a straight answer, no phone tree.
We are plumbers, not water-quality testers. For questions about your drinking water, the Phoenix Water Quality Report and your water provider are the right sources. What we can fix is the leak risk.
Yes, we can repair a failed fitting or section. It is a reasonable choice when a full repipe is already planned, and you need the water back on until then.
It is possible. Sources disagree on exactly when installs stopped, with some citing 1995 and others 1997.
Read the printing on the pipe. PB is commonly stamped as PB2110, and PEX is usually marked with its material type.
New fittings leave the same pipe in the walls, and corrosion from chlorinated water can occur anywhere along the pipe, including stretches far from any joint.
Under a sink, a slow drip or a damp cabinet floor at a fitting. Inside a wall or ceiling, a spreading stain, bubbling paint, or a musty smell. Close the house valve if the water is running and call.
Nobody can tell you how many years your PB has left, and failures do not follow a fixed timeline. The decision comes down to how much risk you are willing to carry.
The disclosure form asks about pipe type; it does not order a replacement. Whether to replace before listing is between you, your agent, and the buyer.
