What temperature should you blow out sprinklers?
To avoid any possibility of damage, sprinkler lines need to be drained prior to temperatures dipping below 32 degrees Fahrenheit. Failing to winterize a sprinkler system before a hard freeze (air temperature is below 0 degrees Fahrenheit) can lead to expensive and time-consuming repair costs.
How cold is too cold for sprinklers?
Sprinkler pipes and other components are at risk of freezing and breaking when temperatures drop below 32 degrees Fahrenheit. Immediate damage can occur to exposed pipes and sprinkler equipment with the first freeze of winter.
Can a pancake compressor blow out sprinklers?
When it comes to sprinkler winterizing, one of the most commonly asked questions goes as follows — can I use my air compressor to blow out my sprinklers? If you have an air compressor with a cubic foot per minute rating in the range of 80 cfm to 100 cfm, the answer is yes.
How big of a compressor do I need to blow out sprinklers?
To properly blow out a sprinkler system, your air compressor needs to provide at least 20 cubic feet per minute. Most irrigation professionals recommend using at least 50 cubic feet per minute.
Should you run sprinklers in winter?
One reason why we recommend running your sprinkler system during the winter is that your plants still need moisture. Overwatering your lawn can also lead to a plethora of problems including fungus, root rot, and plant disease. Plant roots should always be searching for their next meal.
Will pipes freeze at 31 degrees?
Water freezes at 32 degrees Fahrenheit, but indoor pipes are somewhat protected from outdoor temperature extremes, even in unheated areas of the house like in the attic or garage. As a general rule, temperatures outside must drop to at least 20 degrees or lower to cause pipes to freeze.
What time of year should you stop watering your lawn?
You should not completely stop watering your lawn in the fall until the ground freezes. After the ground freezes, it would be pointless to water grass because the frozen ground would act as a barrier, blocking the water’s path to the roots.
Can I blowout my sprinklers myself?
With a basic quick-connect coupling, you can use your air compressor to clear water from your sprinkler system for the winter. Just be aware that even the largest home compressor isn’t powerful enough to blow out the entire system at once. But you can probably blow it out zone by zone.
How do I winterize my sprinklers without an air compressor?
Draining Sprinklers on a Slope
You can winterize a sprinkler system without an air compressor if all of your irrigation lines are buried at a slight downhill slope. Simply shut off the main water supply to your system and open the drain valves at the end of each zone.
Can I blow out my own sprinkler system?
Air pressure is important, but in order to blow out an irrigation system, you also have to pay attention to the volume. High pressure and low volume won’t get the job done. You want high volume and low pressure to eliminate damage and completely blow out your sprinklers.
How much does it cost to blow out sprinkler system?
Summary: Average Cost to Blow Out Your Irrigation System
Most homeowners will spend between $75 and $250 to have their sprinkler system winterized by a professional. The national average reported cost is $81. The minimum cost a homeowner paid was $40 while the maximum reported cost was $250.
How much psi do I need to winterize my sprinkler system?
Air pressure must not exceed 50 pounds per square inch (psi) during the blow out procedure. A pressure-regulating valve must be used to avoid over pressurization of the system. Air volume should be high and air pressure low.
How big of an air compressor do I need?
As a guideline, air compressors meant for powering tools fall in the 30 to 140 CFM range. Air compressors with lower CFM ratings are meant for passenger tire inflation, while higher CFM air compressors are designed for industrial applications.
