A professional spring startup runs $85 to $175 for most Spokane homes as of 2026, depending on system size and how many heads need adjustment. The usual window is April 15 to May 15, after the last hard freeze. Repairs found during startup are billed separately.

What a startup covers
We open the main valve slowly, power up and program the controller, run each zone, check the backflow assembly, and adjust heads so the water lands on lawn instead of the driveway. Cracked heads, split fittings and a freeze-damaged backflow body show up now, not in July.
Spring is also a natural time for the yearly backflow test, since the assembly is being pressurized again.
How it works
- Get on the schedule. Mid-April to mid-May, after the last hard freeze.
- We bring it up slowly. Main valve, controller, every zone, the backflow assembly.
- Green all summer. Heads aimed, schedule set for Spokane's dry summer.
