Can you blow out sprinklers yourself?
Compressor set-up 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 blow out my sprinklers without a compressor?
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.
How many PSI do you need to blow out a 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.
Can I blow out sprinklers through backflow preventer?
Do not blow the system out through a backflow or pump. First blow out the system, then drain the backflow or pump. Do not leave the manual drain valves open after the blow out.
What size compressor do I need to blow out sprinkler system?
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. Most air compressors will list their cubic feet per minute rating on the side of the tank.
Do you need an air compressor to blow out sprinklers?
This is because blowing out your sprinkler system will require an air compressor that can maintain the appropriate pressure (50-80 PSI with 5-6 CFM) for anywhere from 2-5 minutes for each zone of your sprinkler line, when blowing out one zone of your sprinkler lines at a time.
Can you blow out sprinklers with a shop vac?
No, some water there is low risk. The ground will need to freeze at that depth to freeze the water and all the water will need to freeze and not have a place to expand and then enough force to break the pipe. The vacuum created by a shop vac is going to be limited to maximum atmospheric pressure (about 15 psi max).
When should I blowout my sprinklers?
A good rule of thumb is to have your sprinkler system winterized in early fall, but we recommend keeping an eye on the weather, and ensure that your watering system is drained and blown out at least one week prior to the seasons first freeze.

When should I winterize my sprinkler system?
Although you should definitely be thinking about having your system winterized during this time, the rule of thumb is to wait a week before the first hard freeze. The height of winter usually occurs at the beginning or middle of December and that’s when start to notice an extreme temperature drop.
How do you blow out a backflow preventer?
Blowout Quick Tips Shut off water to the irrigation system and drain or prepare to blow out the system. With the air compressor attached to a proper point of connection, use the controller or a remote to cycle through all the valves to evacuate water. Drain the backflow preventer and leave ball valves at a quarter turn.
Can you blow out sprinklers with 6 gallon air compressor?
You need a compressor that has either enough volume or large enough motor to fill your system with pressurized air. A compressor size of 4-6 gallons should be enough.
Is SCFM the same as cfm?
SCFM and CFM are both essential values that indicate the airflow rate in a compressor. SCFM measures this value based on ‘ideal’ temperature and pressure conditions, while CFM measures the ‘actual’ air flow rate. CFM is the recognized value for measuring the airflow rate in the United States.
What kind of compressor do I need to blow out pool lines?
Pretty much any compressor will do the job of blowing out pool plumbing. If you have a compressor, then it should work just fine, and there is no need for you to buy anything else.
What is a fire sprinkler air compressor?
If you have a dry pipe or pre-action fire sprinkler system, you most likely have an air compressor that keeps the air or nitrogen pressurized inside the pipe until a sprinkler head activates, filling the system with water. The air compressor is an integral component to the fire protection system.
How do you clear a clogged sprinkler?
Solution: First make sure to turn of the sprinkler system to avoid incidents. Next you will need to remove all of the sprinkler nozzles and heads. Then turn on the water and let it run until water flows from each head opening to let out any debris inside the sprinkler systems. Then turn the water off again.
Can you blow out sprinklers with small air compressor?
Portable, household air compressors will not have nearly enough power to blow out an irrigation system. Never try to fill up a compressor tank fully then release it all at once to make up for lack of air volume.
How do I manually turn on my sprinkler system?
How do I prepare my sprinkler system for spring?
Dewinterizing Your Sprinkler System Check Your Lawn for Frozen Ground. Before you take the first step toward dewinterizing, you need to make sure your lawn agrees that winter is over. Turn on Your Control Panel. Clean Your Sprinkler Heads. Slowly Open the Main Valve. Check Your Irrigation Zones.
How cold is too cold for sprinklers?
Any temperature below 40℉ is too cold to use sprinklers to water your lawn. Although air temperatures are still above freezing, water droplets clinging to grass blades will be exposed to wind chill or colder nighttime temperatures, which may freeze them solid. This can result in brittle, frozen grass.
