How to tell what kind of pipe you have

The older your home, the more likely you’ll have multiple types of pipe in your home. That’s because older homes have likely gone through various repiping repairs that used newer types of piping to replace the old piping.

To see what kind of pipes you have, check for pipes…

  • Under the sink
  • Connecting to your water heater
  • In the attic

Note: If you can’t easily see any pipes, contact a plumber to locate and pipes. Identify your home’s piping.

Below is a table to help you quickly identify what kind of pipe you have:


We have also included some more detail with links to example photos below...

Copper pipes

Copper pipes have a red/brown (like a penny) color. Copper pipe life expectancy is around 50 to 70 years.

However, copper pipes are susceptible to pinhole leaks, which can significantly reduce their lifespan.

PEX pipes

PEX pipes are made of cross-linked polyethylene (plastic) and can come in a variety of colors, including:

  • Red
  • Blue
  • White

PEX pipe lifespan is around 40 to 50 years.

PVC pipes

PVC is a plastic made of polyvinyl chloride. They are generally white in color and have the letters “PVC” stamped on them. PVC pipes can last 100+ years.

CPVC pipes

CPVC (chlorinated polyvinyl-chloride) pipes are similar to PVC, but they’re usually a cream color that turns tan over time. You’ll usually see the letters “CPVC” marked on them. CPVC pipes usually last 50 to 75 years.

Galvanized steel pipes

Galvanized steel water pipes are a gray metal color. You can also tell you have galvanized steel pipes if you hit it with a coin or screwdriver and you hear a metallic clanging sound.

Galvanized steel water pipe life expectancy is 20 to 50 years.

Galvanised steel pipes aren’t used in newer homes. That’s because, in the 1950’s, it was discovered that the internal zinc lining can cause the pipe to rust and wear out quickly, which can carry those unwanted corroded metals into your home’s drinking water.

Lead pipes

Lead pipes are an outdated pipe material used in homes built pre-1930s. They usually last 40 to 50 years. Lead pipes aren’t used in plumbing systems anymore due to the health problems associated with lead exposure.

Lead pipes are usually gray or a metal color, and you can tell you have lead pipes by lightly scraping the pipe with a screwdriver or sharp object to reveal a silver-white color and soft material.

Galvanized and lead pipes look similar, and the scratch-test will yield the same results, but you can tell the difference by doing a magnet test. Galvanized steel will attract a magnet; lead pipes won’t.

So, should I get my pipes replaced?

You SHOULD contact a plumber to replace your pipes if...

Your pipes are close to their life expectancy.
You have galvanized steel or lead pipes (because of the health risks and unreliability of both types of piping).
