How Often Should You Replace Your Lawn Sprinkler System?

How long is the life expectancy of the average sprinkler system? This system can last up to 20 years, but you’ll likely experience minor breakdowns every 3-10 year, depending on how much you invest in the quality of your sprinkler system. You should also be sure to inspect your sprinkler system as least once a year.

Common Solutions to Fix a Sprinkler System

The cost to replace your sprinkler system can run upwards of $100. When the seasons change for colder weather, be sure you turn the water valve off to the outside. This is a common problem that can cause issues with water pressure and breakage along the lines.

When you try to identify the problem with your sprinkler, it may come down to components in individual zones, or the problem could be with a more central component. These are the usual components of a sprinkler system:

  • The Water Meter
  • The Backflow Prevention Device
  • The Valve Box
  • The Controller
  • The Sprinkler Heads

The most common problems are minor and involve the sprinkler heads. Unlike the most important mechanical components of your sprinkler system, the heads are exposed and can easily be tampered with.

Turn your sprinklers off and take these steps to check for minor problems:

  1. Check for clogs in the filter or nozzle of your sprinkler heads. Dirt can easily get trapped here, so use tweezers to clear clogs.
  2. Check for leaks around the sprinkler heads. A cap may be loose or there could be damage from unusual pressure on the sprinkler head, such as from a lawn mower.

If you do find the sprinkler head needs replacing, be sure you find the correct size for the piece as not to over-water or under-water your lawn.
