Understanding the Lifespan of Residential Plumbing

While the manufacturer may estimate how long plumbing will last, some factors further affect its lifespan.

Residential plumbing can last for many decades, but it's not forever. The obsolescence of the plumbing systems isn't only based on the possibility of fixtures and pipes breaking but also on how they were made. Their longevity impacts home maintenance and renovation, so it's worth knowing how long the installations may last.

So, here is a closer look at home plumbing lifespans:

Lifespan of different pipe materials

Copper pipes may seem soft but usually last between 50 and 70 years. Galvanized steel pipes have a shorter lifespan, between 20 and 50 years, since they're more prone to corrosion than copper. PVC pipes can last forever unless they sustain physical damage. These pipes are usually installed on drain lines. 

There are also PEX pipes made of cross-linked polyethylene plastic. While the technology is fairly new, the plastic material's flexibility promises higher durability and fewer leaks.

Lead pipes are still found in historical homes and older public waterworks, but they are bad news, as lead is poisonous.

What affects plumbing lifespan?

While the manufacturer may estimate how long plumbing will last, some factors further affect its lifespan. For example, hard water can make the pipes corrode faster than higher-quality water that carries fewer minerals. Furthermore, the installations that see more frequent use will wear out faster than those that are used less often. That means a sink in a high-traffic bathroom may wear out faster than a rarely-used garage sink. 

How to know when the plumbing is aging

After learning how long house plumbing may last and what factors affect that lifespan, residents might become more vigilant about the signs of aging. But what signs show that the plumbing system may be on its last leg? These include water discoloration, frequent clogs, leaks (especially recurring), and low water pressure. Any of these could be signs of corroding pipes or overall plumbing deterioration.

How to increase plumbing lifespan

While nothing can halt the flow of time and the inevitable deterioration of materials that come with it, there are ways to slow down plumbing aging. Check for leaks and corrosions and, if found, react promptly, install water softeners, and flush the system to remove sediment. Smart water monitoring can also expand lifespan by detecting leaks and tracking water usage.

However, if the plumbing is experiencing consistent problems or the house is particularly old, consider plumbing replacement rather than trying to fix or preserve it.
