Here’s How to Prepare Your Irrigation System for the Summer!

Getting your irrigation system ready before summer starts is one of the best ways to keep your lawn healthy while avoiding wasted water and expensive repairs. After a long New Hampshire winter, sprinkler systems can develop small leaks, cracked heads, or pressure issues that are easy to miss at first. Taking the time to inspect your system early helps prevent dry spots, overwatering, and higher water bills once the hotter weather arrives. According to the EPA and water conservation studies, as much as 50% of outdoor irrigation water is wasted due to leaks, broken sprinkler heads, overwatering, and poor system maintenance. Let’s avoid these issues!

Start by running each irrigation zone one at a time and watching how the system performs. Look for sprinkler heads spraying sidewalks, leaking valves, uneven coverage, or heads that do not pop up correctly. One easy trick is to place a few empty tuna cans or small containers around the lawn while the system runs. If some containers fill much faster than others, your coverage may need adjustment. This simple test helps beginners quickly spot watering problems like a professional.

Another important step is checking your watering schedule. Many homeowners water too often, which can weaken grass roots and create fungus problems during humid summer weather. Lawns usually respond better to deeper watering a few times per week instead of light daily watering. In New Hampshire summers, watering at night can actually increase the chance of fungal lawn diseases because moisture sits on the grass blades for hours without drying in the morning sun. Early morning is also the best time to run an irrigation system because less water evaporates and the lawn has time to dry before nightfall.

Do not forget to inspect your planting beds and drip irrigation lines as well. Mulch can shift over time and cover emitters or sprinkler heads without homeowners realizing it. Make sure water is reaching shrubs, flowers, and garden areas evenly. A helpful tip is to clean sprinkler nozzles and filters at the start of the season. Dirt and debris can build up over time and reduce performance without being obvious from a distance.

A well maintained irrigation system keeps your landscape healthier, improves water efficiency, and saves money throughout the summer. Most problems are small and easy to fix when caught early. With a simple inspection, a few adjustments, and smarter watering habits, even beginners can keep their irrigation system running like a pro all season long.
