End-of-Season Sprinkler Checkup for Den…

Late summer is one of the best times to check your sprinkler system. By now, your irrigation system has been working hard for months, and small problems are usually easier to spot. Dry patches, leaks, weak zones, and timer issues can all show up after heavy seasonal use.

For homeowners in Denver, Greeley, and nearby areas, an end-of-season sprinkler checkup can help prevent water waste now and make future seasonal maintenance easier.

Why Late Summer Is a Smart Time for a Sprinkler Check

Many homeowners wait until something breaks before calling for sprinkler repair. But by late summer, your system may already be showing warning signs.

A sprinkler checkup can help identify:

Leaking heads or underground lines
Uneven sprinkler coverage
Sprinklers watering sidewalks or driveways
Weak pressure in one or more zones
Broken or clogged nozzles
Timer settings that are no longer efficient
Drip irrigation issues in planting beds

Finding these problems before the season changes can help protect your lawn and landscape.

Look for Dry Spots and Overspray

Dry spots often mean one section of the lawn is not getting enough water. Overspray means water is going somewhere it should not, like the sidewalk, driveway, fence, or street.

Both problems waste resources. One leaves your lawn stressed, and the other sends water away from the plants that need it.

Common causes include:

Tilted sprinkler heads
Clogged nozzles
Poor head spacing
Low pressure
Blocked spray patterns
Leaks in the zone

Calaway Sprinklers can adjust sprinkler heads, repair damaged parts, and improve coverage so each zone works more efficiently.

Watch for Leaks Before They Get Worse

A small leak can turn into a bigger repair if it goes unnoticed. Leaks may also reduce pressure in the rest of the system, making it harder for sprinklers to water evenly.

Signs of a sprinkler leak include:

Soggy grass
Water bubbling from the ground
Mud around sprinkler heads
Standing water in valve boxes
A zone that will not shut off fully
Higher water use without an obvious reason

Leak repair is one of the most important services for protecting both your lawn and your water bill.

Check the Timer or Controller

Your sprinkler timer controls when and how long your system runs. If it is outdated, confusing, or programmed incorrectly, your lawn may receive too much or too little water.

Late summer is a good time to check:

Start times
Run times
Zone schedules
Rain delay settings
Battery backup
Manual operation
Seasonal adjustments

A timer replacement may be helpful if your current controller is hard to use or no longer reliable.

Do Not Forget Drip Irrigation

If your yard has shrubs, trees, garden beds, or xeriscape areas, drip irrigation should also be inspected. Drip lines can clog, shift, leak, or stop delivering water evenly.

Look for:

Dry plants near working drip lines
Exposed tubing
Cracked emitters
Water pooling in beds
Lines pulled out of place by pets, tools, or foot traffic

Drip irrigation works best when it is maintained and matched to the plants it supports.

Conclusion

An end-of-season sprinkler checkup helps Denver and Greeley homeowners catch irrigation problems before they lead to more water waste, lawn stress, or future repairs. By checking coverage, leaks, timers, and drip systems now, you can keep your yard healthier and your system more reliable.
