When Should You Schedule a Sprinkler Blowout in the Treasure Valley?

The best time to schedule a sprinkler blowout in the Treasure Valley is early-to-mid October. Many homeowners wait until the first freezing night appears in the forecast, but by then most sprinkler companies are already booked out.

For most homes in Nampa, Boise, Meridian, Eagle, Kuna, Star, and Middleton, October is the blowout month. Caldwell can see frost earlier, so Caldwell homeowners should be especially careful about waiting too long. If your water is supplied by a city pressure irrigation system or irrigation district, the seasonal shutoff can also shorten your window.

Nampa Pressure Irrigation and Blowouts

Nampa sprinkler blowouts need to be handled correctly because many homes are connected to city pressure irrigation or irrigation district water. The City of Nampa has reminded customers and contractors not to operate city irrigation valves when blowing out sprinkler lines. The city valve is not the same thing as your private sprinkler shutoff.

Beeline works on the private side of the sprinkler system. We shut down and blow out the homeowner side of the system without relying on city owned valves. If you are not sure where your private shutoff, backflow or blowout connection is located. We can help identify it during the service visit.

Can I Blow Out My Own Sprinklers?

Some homeowners try to blow out their sprinkler system with a small garage compressor. The problem is that most small compressors can build pressure but do not have enough air volume to keep water moving through long sprinkler lines. That can leave water trapped in low spots, long laterals, manifolds or the backflow device.

The other mistake is using too much pressure. High pressure can damage sprinkler heads, rotor seals, valve parts and fittings. A proper blowout is about controlled air volume, not just blasting the system as hard as possible.

If your system has multiple zones, a backflow device, long runs, slopes, drip zones or an unclear shutoff setup. It is usually better to schedule a professional sprinkler blowout. You can also visit our sprinkler troubleshooting center if you are trying to diagnose issues before or after the season.
