You can find it with a flashlight. Look beside the water heater in the garage, under the kitchen sink, or near the main shutoff. You may see gray plastic pipe stamped "PB2110." In a house built a few years later, the pipe might be orange or blue and printed with "Kitec" or "IPEX." Either one changes the conversation in a Green Valley sale. Neither one has a settlement fund behind it anymore.
That last part is the real story for buyers and sellers in Green Valley right now. Both pipe types once had class-action money attached. Those claim windows have closed. So the cost of original problem pipe now sits with whoever holds the deed, and in a sale it gets passed back and forth through negotiation.
The money that used to cover this is gone
Polybutylene was the subject of the Cox v. Shell settlement. Public Justice describes it as offering at least $1.103 billion in relief, with a claim deadline of May 1, 2009. The settlement administrator's FAQ says it was a nationwide settlement for qualifying systems installed between January 1, 1978 and July 31, 1995. Recovery depended on a qualifying leak.
Kitec was a Southern Nevada story in particular. In 2008 the Las Vegas Sun reported a tentative $90 million settlement in a class action covering at least 34,000 Southern Nevada homeowners. The Sun said Kitec was used in local residential construction from 1995 to 2006. In 2009 the Las Vegas Review-Journal reported that Del Webb/Coventry separately agreed to pay $27.2 million to 6,617 homeowners, on top of the IPEX settlement. The official Kitec settlement site lists the claim deadline as January 9, 2020. Its July 9, 2025 update reports that settlement payments have been issued.
For a home changing hands this fall, there's no third party left to call. If original pipe fails after closing, the new owner pays. A seller with a documented repipe has taken that risk off the table for the buyer. That's why the paper trail on a Green Valley home can be worth more at the negotiating table than its square footage suggests.
Green Valley's build waves line up with the pipe eras
Green Valley's first homes opened in 1978. A Henderson plumbing company, Active Plumbing, breaks the area's construction into three rough waves. Put those waves next to the pipe timelines and the overlap is plain to see.
| Build wave, per a local plumber | Approximate build years | Pipe era it overlaps |
|---|---|---|
| Early Green Valley core, near Green Valley Parkway and Sunset | 1978 to 1988 | Polybutylene, made for home plumbing from 1978 to mid-1995 |
| Green Valley Ranch expansion | 1994 to 2007 | Tail end of polybutylene, then Kitec, used locally from 1995 to 2006 |
| The District and later infill | 2004 to 2010 | Overlaps the last years of Kitec use |
InterNACHI, the inspector association, dates polybutylene production for household plumbing from 1978 to mid-1995 and estimates it went into as many as 10 million U.S. homes. That's a national figure, not a Las Vegas count. Nobody has published an independent count of Green Valley homes with either pipe. What exists is contractor experience. The Henderson plumber says some late-1980s and early-1990s Green Valley homes have polybutylene. Its Kitec article names Green Valley among the areas where it finds Kitec, especially in homes built between 1995 and 2007.
So a build year tells you what to look for, not what's actually there. A home's age alone can't tell you what remains after a partial or full repipe. The build year is where your questions start.
Henderson's water speeds up the clock
Every Green Valley home, whatever its pipe, runs on very hard water. The City of Henderson's 2026 water quality report puts tap-water hardness at typically 304 parts per million, or 18 grains per gallon, which it classifies as "very hard." The report covers results from January 1 through December 31, 2025.
That hardness was at the center of the Kitec fight. The Sun reported that brass Kitec fittings corrode as zinc leaches out and builds up inside the pipe, restricting flow until the pipe breaks. IPEX recalled the brass fittings in 2005 but denied liability, arguing that Southern Nevada's hard water caused the failures. Local plumbers say the same minerals leave scale inside older copper and galvanized lines. They also link Green Valley's older galvanized pipe to rusty water and falling pressure.
Why polybutylene fails is still argued. InterNACHI points to disinfectants in the water weakening the pipe wall. Local plumbing material puts more weight on joints and fittings. For a buyer, the cause matters less than the consequence. Both explanations put the risk inside the pipe or at its connections, where you can't see it.
A clean inspection doesn't settle it
InterNACHI notes that a standard visual home inspection can't detect internal deterioration. It also says polybutylene can remain at fittings even where the visible plumbing is copper. Polybutylene isn't always gray, either. InterNACHI lists gray, silver, black, white and blue, sometimes printed with "PB2110." Kitec tends to show up as orange, blue or gray pipe labeled Kitec, IPEX, PlumbBetter or KERR, often near the water heater or a manifold.
Copper at the water heater tells you what one stretch of pipe is made of, so the evidence for the rest of the system has to come from the home's records.
Building the paper trail on a specific house
These steps use public tools, and both sides of a deal can run them before the inspection contingency gets tight.
- Confirm the build year. The Clark County Assessor's Real Property Records search lets you look up a parcel by address, parcel number, owner or subdivision. The Assessor notes that its city field reflects the parcel's legal boundary, not its mailing city.
- Search Henderson's permit history, not the county's. Green Valley is inside the City of Henderson, and Henderson's Building and Fire Safety department keeps permit records by address for public access. Its DSC Online portal covers permits, plans, inspections and licenses. The city's construction terms reference says a plumbing permit is required for new plumbing and larger changes to existing plumbing. A finaled plumbing permit at the address is the strongest evidence a seller can offer that a repipe happened.
- Look where pipe shows. Check the water heater, under every sink, and at the meter or main shutoff, and look for printed labels.
- Read the seller's disclosure closely. Nevada's Seller's Real Property Disclosure form, revised 6/1/2023, asks about plumbing, heating and cooling, roof, water supply and other material conditions. It requires any "yes" answer to be explained. Under NRS 113.130, the seller must complete the form and serve it at least 10 days before conveyance, with listed exceptions. The form asks about known conditions. A seller's knowledge is not a pipe survey.
While you're in the permit records, check two more era-related items. A Henderson HVAC company says many older Green Valley homes still have original systems running on R-22 refrigerant, which it calls past their service life and increasingly expensive to recharge. A Las Vegas inspection company notes that concrete roof tiles can last 40 to 50 years or more, but the underlayment beneath them wears out sooner. It suggests asking for re-lay history because a standard inspection can't certify what's hidden under the tile.
Call the insurer before you count on the deal
Pipe material can show up again at the insurance step, which a financed buyer can't skip. Nevada's Division of Insurance says insurers weigh risk factors including a home's age, and that mortgage lenders may require homeowners coverage. Its consumer guidance doesn't set any polybutylene-specific rule. A Las Vegas home inspection firm reports that some carriers charge higher premiums, add exclusions or decline coverage for homes with polybutylene. That varies by carrier, so get a quote on the specific address with the plumbing disclosed while you still have time to respond.
For sellers, the math works the other way. If a repipe was permitted, save the paperwork and offer it up front. For an early-core or Green Valley Ranch home, that one document answers the question every informed buyer is about to ask.
On price, the same Henderson plumber estimates a whole-home repipe at roughly $4,000 to $15,000, depending on the home. Treat that as one contractor's range, and get bids on the actual house before building it into an offer or a credit.

Quick answers
Can I still file a polybutylene or Kitec settlement claim? No. The Cox v. Shell claim deadline was May 1, 2009, and the Kitec deadline was January 9, 2020.
Does a 1990s build year mean the house has problem pipe? No. It tells you which material to look for. The pipe may have been partly or fully replaced since then, which is why Henderson permit records matter more than the build year.
Does a newer Green Valley home avoid all of this? Not necessarily. The Kitec era in Southern Nevada ran from 1995 to 2006, which overlaps Green Valley Ranch construction.
Whether you're pricing a Green Valley home you've owned since the 1990s or writing an offer on one, the plumbing history affects both the negotiation and the financing.
