Why Las Vegas Homes Built Before 1995 Need a Plumbing Check

You bought your home in a nice Las Vegas neighborhood. The house looks great. The roof is fine. The AC works. Everything seems solid. But there is something hiding behind your walls that could cost you tens of thousands of dollars, and you probably have no idea it is there.

If your home was built before 1995, there is a very good chance your plumbing is a ticking time bomb. Not because anyone did anything wrong when the house was built. The materials they used back then were considered perfectly fine at the time. We just know better now.

The problem is that most homeowners do not find out about this until water is pouring out from under their floor. By then, the damage is done. Here is what you need to know before that happens to you.

The Three Pipe Types That Are Failing Across Las Vegas

Polybutylene (Gray Plastic Pipes)

If your home was built between the late 1970s and mid-1990s, you might have polybutylene pipes. They are gray, flexible, and they were installed in millions of homes across the country. The problem is that the chlorine in our water supply eats away at this material from the inside. The pipe looks fine on the outside, but it is getting weaker every day.

These pipes have been the subject of a massive class action lawsuit. They are no longer manufactured. And when they fail, they do not just drip. They burst.

Copper Pipes

Copper was the gold standard for decades. But in Las Vegas, our extremely hard water is brutal on copper. The minerals eat tiny holes in the pipe walls, creating what plumbers call "pinhole leaks." These leaks are small enough that you might not notice them for months, but they are slowly soaking your walls, your foundation, and your subfloor.

If your copper pipes are 25 to 30 years old, they are in the danger zone. And replacing copper with more copper is not the answer.

Galvanized Steel Pipes

These are the oldest pipes you will find in Las Vegas homes, typically in houses built before the 1970s. They rust from the inside out, slowly choking off your water flow. If you have noticed your water pressure getting weaker over the years, or if your water has a brown or yellow tint, galvanized pipes are likely the reason.

Why This Matters Right Now

Here is the part that really hurts. If your old pipes cause a slab leak or a major water event, your insurance company may not cover it. Many insurers in Nevada are now classifying old polybutylene and corroded copper pipes as "worn out" and denying claims. They will say the pipes were bound to fail and that it is your responsibility to maintain them.

That means you could be stuck paying for the plumbing repair, the water damage restoration, the mold remediation, and the foundation repair all out of pocket. We have seen these bills reach $50,000 or more.

What You Can Do About It

The good news is that this is a completely solvable problem. A whole house repipe replaces all of your old, failing pipes with modern PEX-A, a flexible plastic pipe that is built to handle Las Vegas water. It does not corrode, it does not scale up, and it does not burst.

The process takes about 3 to 5 days, including the city inspection. And the cost is a fraction of what you would pay to deal with a catastrophic pipe failure after the fact.

If you are not sure what kind of pipes you have, that is okay. Most homeowners do not know. That is exactly why we offer free plumbing inspections. We will come out, look at your system, and tell you honestly what we find.
