When Should a Sprinkler System Be Winterized to Prevent Freeze Damage in Colorado?

End of October (Usually)

As you know the weather in the Boulder and Fort Collins area is unpredictable. Our recommendation is to have the system ready for winter before October 25th; however, this date can vary depending on the seasonal temperatures. Some seasons we have had hard freezes as early as the first week of October and other seasons our first hard freeze is around Thanksgiving.

Schedule Early!

Our schedule is very full around October 10-October 25th so schedule your sprinkler blowout for your Boulder or Fort Collins area home early!

What if a Sudden Freeze is Coming?

Hard freezes come and go. If you know how to drain the basement pipe, the backflow preventer also known as the vacuum breaker, and how to drain the valves then this can be done before a sudden freeze to prevent damage to the sprinkler system.

Do You Need to be Home for the Sprinkler System Winterization?

Drain Your Own Basement Piple!

You DO NOT Need to Be Home

This depends on whether you are comfortable draining the water from your basement pipe by yourself. If you know how to shut off the water to the sprinkler system and drain the basement pipe, you do not need to be home for us to blow out your sprinkler system. We will operate each sprinkler zone using the valves in the green valve boxes, and we usually do not need access to the sprinkler clock.

Learn How To Drain The Basement Pipe of Your Sprinkler System

If you, the homeowner, can drain the basement pipe properly, then our sprinkler technician will not need to meet up with you to be able to blow out the sprinkler system. We will be able to blow out the sprinkler system using the valve boxes and we will not need access to the basement.

Step-by-Step Instructions

We Will Do it for You BUT…You Will Need To Be Home if You Want Us To Do it For You!

These sprinkler system arrival times have a 1-2 time window so you will not need to wait around all day.

You might enjoy the fact that you don’t have to be home for the sprinkler blowout or you might want to be home. Either way, we can help make sure that your sprinkler system will work properly when you start it up the following spring.
