Is your irrigation system outdated (5+ years) or constantly needing repairs? It sounds like your system may be in need of an update.

At Sentry Irrigation we only use the latest advanced parts when performing repairs and upgrades to irrigation systems.

In some systems, a part may be working, but its performance is poor due to age which then causes water leakage or uneven water distribution.

Or, it may be that a part was never installed on your system. In that case, it is best to review and replace all outdated parts with the newest technology. This approach will save you money in the long run by eliminating water waste and costly repair bills due to frequently breaking parts.

A thorough upgrade of your irrigation system will also restore your system’s ability to properly and efficiently distribute water to prevent landscape issues like fungus or leaf burn.


Perhaps your system installation contractor didn’t install a rain sensor, or a spray head needs to be moved due to landscape changes. In this case, you need some add-on or system change work. Missing components or outdated watering layouts can cost you more than you think and should be taken care of as soon as possible to keep your landscape in great shape and to save you money.
