What is the life expectancy of PVC once installed?

Author: Laurianne Hegmann  |  Last update: Friday, November 7, 2025

Based on stress regression, slow crack growth and fatigue testing, the service life of PVC pressure pipe should exceed 100 years. The Water Research Foundation reported that 100 years is a conservative estimate for a properly designed and installed PVC pipe.

How many years will PVC pipe last?

The lifespan of PVC pipes is estimated to be around 100 years, though this isn't an exact figure because PVC pipes have only been used in the U.S. since the 1960s. What contributes to a long lifespan, however, is the material's chemical stability and the fact that it is resistant to corrosion.

How often do PVC pipes need to be replaced?

Pipe Material

Regardless of the material, each of these plumbing products have a life span that you should know so you can gauge whether you need an upgrade. Brass, cast iron, and galvanized steel have a life span of 80 to 100 years, copper lasts 70 to 80 years, and PVC piping only survives for 24 to 50 years.

How long does it take for PVC pipe to degrade?

Factors That Affect The Lifespan Of PVC. PVC pipes typically have a lifespan of 100 years.

What is the life expectancy of PVC trim?

PVC trim is known for its long lifespan, often lasting 25 to 50 years or more, depending on the installation and environmental conditions. Its resistance to moisture, rot, insects, and weathering means it can maintain its integrity far longer than traditional wood trim.

Does PVC degrade over time?

Based on stress regression, slow crack growth and fatigue testing, the service life of PVC pressure pipe should exceed 100 years. The Water Research Foundation reported that 100 years is a conservative estimate for a properly designed and installed PVC pipe.

What is one problem that one might have by using PVC trim?

Thermal Expansion

When the PVC gets hot, such as when it sits directly in the sun, the trim will actually expand or grow. If will then shrink again once it cools. This won't damage the trim, but it can cause issues with its bonding to other surfaces. It may also cause the paint on its surface to peel and crack.

How long will schedule 40 PVC last outside?

Schedule 40 PVC pipes generally have a lifespan of 100 years or more when properly installed and maintained. They are highly durable and resistant to damage from weather, chemicals, temperature changes, and pressure changes.

At what temperature does PVC start to degrade?

observed that the degradation of polyvinyl chloride occurs in two steps at 200–380°C and 380–550°C. The first step is associated with the elimination of chlorine, and the second step is related to the degradation of remaining part which decomposes at the same temperature as observed for other plastics.

How do you know if PVC pipe is bad?

Signs that your PVC pipe may be bad include cracks, leaks, discoloration, or a foul odor coming from the pipe.

What is the life expectancy of PVC plastic?

Because PVC is immune to corrosion, a minimum service life of at least 100 years can be expected. This figure is supported by a number of independent studies, as well as the experience of many long-term users of PVC piping systems.

How can I make my PVC pipe last longer?

Maintenance
  1. Use a mild detergent and warm water to clean fittings exposed to dirt and debris.
  2. Apply a small amount of silicone lubricant to the fittings to reduce cracking and prevent wear and tear.
  3. Keep PVC fittings within their recommended temperature range to prevent damage.

When should PVC pipes be replaced?

Copper pipes can last up to 70 years, while PVC (polyvinyl chloride) pipes have a lifespan of around 50-70 years. If pipes at your homes are approaching or have exceeded their expected lifespan, it may be the right time to consider a replacement. Water pressure is an essential aspect of your plumbing system's comfort.

What is the life cycle of PVC pipe?

The energy required to pump water through a pressurized pipe system over the life of the pipe is a significant source of potential environmental impacts. The energy required to pump water through PVC pipe over a 100-year design life remains constant because its smooth walls do not roughen over time.

What deteriorates PVC pipe?

Due to its porous nature, PVC can be damaged by an excess of cement. Conversely, when too little cement is used, it can cause the pipe to leak or break. Any debris, burrs, or other potential residue-causing elements should be eliminated before installation begins.

How long does it take for PVC to deteriorate?

PVC important? Recycling PVC is essential as it can take more than 450 years for PVC to biodegrade if it ends up in landfill. The chemical composition of PVC also means these chemicals can leach into the nearby ground, water, and air.

At what temperature will PVC pipes burst?

As mentioned in the previous section, once the outside temperature drops below freezing (32°F), your pipes are at risk of freezing. However, the chances of damage increase as temperatures drop to 20°F or below.

Does PVC pipe get brittle with age?

Over time, ultraviolet radiation will degrade through the polymer, thereby reducing the flexibility of the material, causing splitting and cracking. With the advent of winter; the temperature drops, PVC becomes more and more brittle.

How often does PVC need to be replaced?

FAQs: How long do PVC pipes by TMT Plus last? TMT Plus PVC pipes are made to last more than 50 years, as they have corrosion-free and high-impact strength properties, ensuring safe drinking water.

What is the best PVC for outdoor use?

CPVC plastic pipes are your best bet when installing water pipes for internal and external (exposed to sunlight) household applications.

Is PVC better than PEX?

PVC and CPVC are more cost-effective than PEX if you price clients by the hour, as they require many fittings secured by clamps cement. PVC and CPVC have more strength and durability than PEX because they are more rigid, making them better suited to outdoor applications where the piping may be subjected to trauma.

Do you nail or screw PVC trim?

Fastening your PVC Trim Boards

When selecting your fasteners, stainless steel screws are the best options because they will never rust and prevent the board from bleeding if the PVC board is unpainted.

What is the problem with PVC plumbing?

PVC piping, like all plastics, becomes stiffer and more brittle with low temperatures. Damage from frozen water within a system is the most common problem associated using PVC for cold temperatures. If the water or liquid does not freeze, expansion does not take place and PVC can be effectively used.

Why is PVC trim so expensive?

Disadvantages of Exterior PVC Trim

Not surprisingly, because of its intrinsic strength, PVC is also the more expensive product when compared to wood.
