In Montana, the change of seasons happens fast. To protect your investment and ensure a lush, green landscape all year long, your sprinkler system requires professional attention at both ends of the season.

At Mann Landscape & Sprinklers, we provide comprehensive seasonal maintenance to help homeowners in Kalispell and the surrounding areas spend less time worrying about their yards and more time enjoying them.

Spring Sprinkler Startups: Get Growing

Our Spring Startup Service Includes:

  • Controlled Re-Pressurization: We slowly introduce water back into the main lines to prevent “water hammer” damage to your pipes and valves.

  • Zone-by-Zone Inspection: We manually test every zone to ensure valves are opening and closing correctly.

  • Head Adjustment & Cleaning: We clear debris from nozzles and adjust spray patterns to ensure water lands on your grass—not your driveway or siding.

  • Controller Programming: We set your watering schedule based on current seasonal needs and check for backup battery health.

  • Leak Detection: A thorough visual inspection for any winter-related breaks or hidden underground leaks.

Fall Sprinkler Blowouts & Winterization

Frozen pipes can lead to malfunctioning valves, burst lines, and cracked backflow preventers. Before the first hard freeze hits the Flathead Valley, it is critical to have all water professionally evacuated from your system.

Why Professional Blowouts Matter: Standard shop vacs or small compressors often lack the volume (CFM) necessary to clear all water from low spots in your lines. We use high-volume, regulated air compressors to safely and effectively “blow out” the entire system.

Our Winterization Process:

  • Main Line Shut-off: We isolate the water source and drain the primary connection points.

  • High-Volume Air Purge: We cycle through each zone until only air is exiting the heads.

  • Backflow Protection: We ensure your backflow assembly is drained and left in the correct position to prevent internal freezing.

  • System Power-Down: We set your controller to “Off” or “Standby” to save energy and protect the electronics through the winter months.

Protect Your Landscape Today

Don’t wait until the first frost or the heat of July to realize your system needs attention. Our maintenance slots fill up quickly during the peak spring and fall weeks.
