How Long Do Underground Pipes Last?

Open-trenched view of underground pipe lines

The lifespan of underground pipes varies significantly. Conditions factoring into the longevity of any underground product include use, soil conditions, and the type of material used. Besides that, the quality of installation and maintenance also matter. Below, we take a close look at the various factors that affect underground pipe longevity.

Corrosion and Chemical Damages

Cast iron pipes and PVC are materials known for their durability. Their weak point is the risk of corrosion. Cast iron can last about 100 years with the correct maintenance. Eventually, corrosion will damage it. PVC has a 50-year lifespan, but corrosion and chemical damage are problems. This is of particular concern when users frequently flush corrosive drain cleaners and similar substances through the pipes.

Cracking and Root Intrusions

Concrete pipes also have the potential to last for a century. However, here, the installation expertise of the technicians will be tested. Shifts in soil stability and errors will result in cracks over time. Clay is known for its longevity, measured in centuries. Corrosion is no problem. What eventually leads to leaks and cracks is the intrusion of tree roots.

Consider 50-Year Approximate Lifespans

Two of the best materials we have found are copper and HDPE (high-density polyethylene). Both can resist corrosion, intrusive tree roots, and environmental conditions. They have a good track record of weathering local soil conditions, water chemistry, and the presence of aggressive elements in the ground.

Of course, a regular inspection and maintenance schedule will ensure that these underground pipes reach their whole anticipated lifespan. While customers frequently wait until they experience water discoloration, reduced water pressure, or the presence of sinkholes in the yard, we gladly come out and perform routine maintenance even if everything is fine.
