A well-maintained sprinkler system keeps your lawn green and healthy while using water efficiently. A neglected system wastes water, creates dry spots and soggy areas, and eventually breaks down with expensive repair bills. Seasonal maintenance takes minimal effort and saves significant money over the life of your system.

Spring Startup

After a long winter, your irrigation system needs a careful startup to avoid damage. Never just turn the system on at full pressure after months of dormancy. Air trapped in the lines can cause pressure surges that crack pipes and blow out sprinkler heads.

Start by slowly opening the main water valve, allowing pressure to build gradually over several minutes. Then run each zone manually for a few minutes while you walk the yard and inspect every sprinkler head. Look for heads that are not popping up, heads that are spraying in the wrong direction, heads that are broken or cracked, and any areas where water is bubbling up from underground, indicating a broken pipe.

Check the controller settings. Winter power outages may have reset your programming. Set appropriate spring watering schedules, which typically means two to three days per week in the early morning hours. Morning watering between 4 AM and 8 AM minimizes evaporation and reduces the risk of fungal disease.

Professional spring startups cost $75 to $125 and include system pressurization, head inspection, controller programming, and a basic system test. For homeowners who are not comfortable doing this themselves, it is money well spent.

Summer Optimization

Summer is when your sprinkler system works hardest and when inefficiencies cost the most. A system that wastes 20 percent of its water during peak summer months can add $30 to $60 per month to your water bill.

Adjust your watering schedule as temperatures and rainfall change. Most lawns need one to one and a half inches of water per week. Place a rain gauge or a tuna can in your yard to measure how much water your system delivers in a typical cycle. You may be surprised to find you are overwatering some zones and underwatering others.

Check for head-to-head coverage, which means each sprinkler head's spray pattern should reach the adjacent head. Gaps in coverage create dry spots, while overlapping too much wastes water. Adjust head arc and radius as needed.

Replace clogged nozzles promptly. Mineral buildup and debris can restrict flow and create uneven spray patterns. Replacement nozzles cost $2 to $5 each, and swapping them takes less than a minute per head.

Consider adding a smart controller if you do not already have one. Smart controllers like Rachio or Hunter Hydrawise connect to weather data and automatically adjust watering based on temperature, rainfall, wind, and soil moisture. They typically reduce water usage by 20 to 50 percent compared to traditional timers, and they cost $150 to $300 installed.

Fall Preparation

As temperatures cool and your lawn's water needs decrease, gradually reduce watering frequency. Continue running the system until the first hard frost, but cut back to once or twice per week.

Fall is the ideal time to address any repairs you have been putting off. Replacing broken heads, fixing leaking valves, and repairing damaged pipes are all easier and less urgent before winter arrives.

Winterization

In any climate where temperatures regularly drop below freezing, winterizing your sprinkler system is essential. Water left in the pipes, valves, and heads will freeze, expand, and crack components, leading to expensive spring repairs.

Professional winterization, commonly called a blowout, uses compressed air to force all water out of the system. The process takes 30 to 60 minutes and costs $75 to $150 for most residential systems. This is one maintenance task that is strongly recommended to leave to a professional, as improper blowout technique can damage components.
