Quality PEX manifolds are considered the norm in modern residential spaces. But this doesn’t inherently make them a good option. So, how long do PEX manifolds last?
The answer is more involved than you’d think.

How Long Do PEX Manifolds Last?
PEX manifolds last between 25 and 50 years, with the company offering a 10-year warranty. PEX fittings and pipes, on the other hand, come with a 25-year warranty. If PEX products are used with other pipes and systems, the warranty may be limited to five years or less.
So, if you’re planning to install a PEX manifold or piping in your acrylic kitchen sinks, the warranty may provide very little protection. It’s important to note that for the terms of the warranty to apply, you may need to hire an authorized party to install the PEX products.
Is Copper Plumbing Better Than PEX Plumbing?
Copper plumbing has been relied upon as a water delivery system for centuries. Ancient Egyptians used copper pipes for plumbing around 2150BC. By the 1940s, most of the developed world used copper plumbing material. In fact, as much as 80% of service lines comprise copper plumbing.
It’s not hard to see why copper is seen as the traditional plumbing choice, and installing copper plumbing is still worth considering today.
Benefits of Copper Plumbing
- Copper pipes last longer than PEX pipes, typically serving their purpose for between 50 and 70 years. In contrast, PEX plumbing can be expected to last between 30 and 50 years.
- Copper is known to be more durable than PEX since it isn’t susceptible to damage by sunlight and rodents. Copper pipes can handle water pressure of up to 1,000 psi and deal with hot and cold conditions just as well as PEX.
- Since copper plumbing is recyclable, it’s more environmentally friendly than PEX plumbing. Additionally, copper plumbing doesn’t have some of the chemicals that PEX pipes do.
Drawbacks of Copper Pipes
- Copper plumbing tends to cost between 58% and 68% more than PEX plumbing.
- Installing copper plumbing for your dual-mount or undermount sinks can be more challenging and requires soldering with a torch to connect fittings.
- Water loses more heat traveling through copper pipes than plastic pipes, leading to increased energy consumption.
Comparing Your Options
Investigating the water quality in your home will give you a better perspective on which plumbing is right for you. If the water is acidic, copper plumbing will degrade faster. But if the water has high chlorine levels, PEX plumbing will wear out quickly.
You must also consider the possibility of frozen pipes and ill-fitting ball valves. If your home is well-insulated, this shouldn’t be a problem. But not every home is built prioritizing insulation. PEX plumbing is the better option if you’re concerned about the pipes freezing.
Conclusion
While PEX manifolds are used to facilitate water distribution and can be expected to last at least 25 years, copper plumbing will serve you for 50 years. But you will also need to pay roughly double the price for copper plumbing and deal with the disadvantages. Weighing out the pros and cons of both plumbing solutions is the best way to find the right one.
