We all know how important it is to have a well-watered lawn – it’s the foundation of a healthy landscape! But did you know that your sprinkler wire plays a big role in keeping your irrigation system running smoothly?

Just like any other type of electrical wiring, over time, sprinkler wire can go bad due to weather conditions, exposure to sunlight and water, or even pests chewing through it.

While the lifespan of sprinkler wire can vary depending on a number of factors, with proper care and maintenance, you can extend the life of your wire and prevent it from going bad.

Read on to learn more about the lifespan of sprinkler wire and how you can prevent it from going bad.

The Lifespan of Sprinkler Wire

Sprinkler wire, like most electrical wiring, can definitely go bad over time. The lifespan of the electric wire can be impacted by both outdoor and indoor weather conditions, making it especially vulnerable to wear and tear.

Underground wires are particularly susceptible to damage from burrowing animals or root intrusion. In fact, one study found that nearly 50% of all underground cables were damaged by rodents!

How often should you replace your sprinkler wire?

A good rule of thumb is to replace the wire every five years or so. This will help ensure that your system is running efficiently and that there are no weak spots in the wire that could lead to problems down the road.

When replacing the wire, be sure to use gaskets when connecting the sprinklers and nearby watering valves – this will help reduce the risk of corrosion or other damage occurring.

Additionally, make sure that the new wire is properly buried below ground level to protect it from potential damage.


Sprinkler wire is an essential component of any lawn irrigation system – but it doesn’t last forever! Over time, exposure to weather conditions, sunlight, water, or even pests can cause sprinkler wires to go bad.

However, by replacing the wire every five years and taking steps to protect it from damage, you can extend the life of your sprinkler wire and keep your irrigation system running smoothly for years to come.
