The startup and shut down of your irrigation system for the season. This is to include the labor and compressor (for fall shut down) for the season. In the spring (startup) it includes charging the system up and going through each zone to make sure heads are working properly, (popping p, rotating, covering areas that each head is supposed to cover and setting controller). If repairs are necessary there will be additional charges for labor and materials. In the fall we will come in and turn off the main water source, remove back flow and blow out each zone individually. Normally start up and shut down takes about 3 hours at the current hourly rate.
