Buying Guide

Your Current System

There are several considerations to keep in mind when looking for the best air compressors for blowing out sprinklers.

Your goal should be to read up on your current sprinkler system and match the air compressor to the recommended specifications of your sprinkler manufacturer.

You want the compressor you use to not damage your system or not be compatible with it.

PSI and CFM

Some of the main things to consider are the size, PSI, and CFM of the air compressor in question. CFM, or air volume, is highly relevant due to needing to have enough power to blow air through pipes.

PSI is a rating of how much pressure or stress can be used at any given moment. You need a strong PSI, but not an excessive amount, to blow out sprinkler lines.

Size

The size of your sprinkler blowout compressor will determine the capacity of the machine. If it is too small, you will find yourself recharging it too many times while completing your winterization project.

But also bear in mind that an air compressor that is terribly large and weighs a lot will be harder to transport around a property to the sprinkler hookups.

Noise Level

Other elements to look for in an air compressor to blow out sprinkler system are the noise level, maintenance requirements, and convenience.

Because you will be using it for extended periods of time to blow out water lines, you want a relatively quiet air compressor.

Many brands have quiet designs that do not put out more than 60 or 70 decibels. Check for something that indicates indoor use because those models will be quieter.

Maintenance

You should also know what type of maintenance is involved with the air compressor for sprinkler blowout you pick. Some options are designed to be oil-free.

You will not have to change oil or worry about a mess with those compressors.

Convenience

Convenience is also a major factor in an air compressor. Look for lightweight designs for easy mobility and other convenient features.

For example, a corded air compressor would ideally come with storage space for the cord.

Safety

Finally, take into account safety when purchasing an air compressor to blow out the sprinkler system. Many models have electric-powered motors, which are strong and not as messy as gas-powered.

However, electricity near water can be dangerous if you do not take precautions. Be aware of where your hook-up is located and how close the air compressor will be to the spraying sprinkler heads during a blowout.

What Size Air Compressor Do You Need for Blowing a Sprinkler Line?

If you select an air compressor that is too small, you may not be able to efficiently blow out your sprinkler lines.

An air compressor to blow out a sprinkler system generally has to be capable of working without needing to recharge.

Small-sized tanks, such as those between 1 and 5 gallons, take a long time to recharge once emptied. You need at least a 10-gallon tank to ensure that the air compressor can keep up with the demands of blowing out the sprinkler lines.

A larger air compressor will be heavier to move around. If you plan to take the compressor around your property, you might need one with better mobility.

Large air compressors, however, often come equipped with wheels. In the end, you should consider the size of the sprinkler system you need to blow out. The gallon capacity of an air compressor is just one aspect that you need to consider.

What Does an Air Compressor Require in Terms of PSI for Blowing Out Sprinklers?

The best air compressor will have a pressure regulator that lets you set the PSI rating. Depending on the size and type of pipes in your sprinkler system, you should set this regulator between 50 and 80 PSI.

80 PSI is a good mark for rigid PVC pipes, while less pressure is good for flexible pipes. For example, use 50 PSI for flexible black polyethylene pipes.

PSI, or pound-force per square inch, is a measure of the amount of pressure being applied in a period of time. Higher PSI in an air compressor means that it can provide more force.

Look for air compressors that have a high PSI so that you can drain all the water from the lines efficiently. You should be careful to not put too much stress on your sprinkler system, which can damage the pipes, valves, and heads.

How Many CFM Does an Air Compressor Need to Blow Out your Sprinkler System?

CFM stands for cubic feet per minute. This measure tells you the flow rate of the air compressor or the amount of air it produces at a given pressure level. Put in plain terms, this is the air volume.

Look out for a sprinkler blowout compressor that provides at least 20 CFM. This is the minimum amount of air volume to blowout sprinkler systems. Check your system to see the pipe size.

Larger lines will naturally need more air volume than smaller lines. The air volume in cubic feet per minute can be found on the tank of the compressor.

A good rule to follow for an air compressor for sprinkler blowout is that the larger the pipe diameter, the high the CFM you will need.

You can also get away with lower CFM ratings if you choose to work zone by zone on your sprinkler system. Clearing out smaller zones only requires about 6 CFM.

The Importance of Winterizing your Sprinkler System

A sprinkler system for your home is a major investment for your property. You spend a lot of money on installation and materials so that you can water your lawn effectively throughout the spring and summer.

The effect of harsh winters on your sprinkler system’s pipes is probably something you do not want to mess around with after the spring thaw. Winterizing your sprinkler system is the only option to prevent costly repairs.

You cannot afford to neglect your sprinkler system, especially before winter. While you are winterizing other aspects of your home at the end of each fall, plan a time to use an air compressor for blowing out water lines. The result of not winterizing your sprinkler lines will be burst pipes and a significant repair bill in the springtime.

Owning an air compressor of your own is a great way to get a jump on winterizing your irrigation systems. An air compressor to blow out sprinkler system can help you drain your water lines before the first winter freeze.

Avoid the headache of a frozen sprinkler system and all the burst pipes, damaged valves, and broken sprinkler heads that come with it.

How to Winterize a Sprinkler System?

The air blowout method, which uses a sprinkler blowout compressor, is a tried and true way to winterize your sprinkler system. Professionals recommend this method as an effective and safe way to prevent freezing pipes.

Once you have purchased a high-quality air compressor for sprinkler blowout, you are ready to get started. Check out our step-by-step guide to see how it is done.

Step 1: Shut the Water Off

First, you will locate turn off the water to the system at the main valve. This valve is often situated by your home’s water meter. You need to shut off any backflow valves, too.

Step 2: Turn the Automatic Timer Off

A system that has an automatic timer needs to be turned off. You can either shut it off completely or put it on a “rain mode.” This setting turns off the timer, but will not get rid of your programmed timers.

Step 3: Hook Up the Air Compressor to the Sprinkler System

To winterize with the blowout method, you need to hook up an air compressor to the sprinkler system directly. If your compressor did not come with an adaptor, you will need to purchase one from a hardware store.

You should also start with a fully charged sprinkler blowout compressor. You should also wear eye protection at all times while using a powerful air compressor to blow out the sprinkler system.

Step 4: Apply Air Slowly

As you start up the air compressor, apply air slowly to the system. Pay attention to the recommended PSI rating for your particular sprinkler piping and do not exceed that PSI.

Step 5: Spend Time Blowing Air Into Lines

The compressor needs to be engaged for enough time to completely clear the water out of the pipes. Most sprinkler systems will need to be cleared zone by zone, so expect to spend 2 to 5 minutes per zone.

The most important step of winterizing your sprinkler system is using the sprinkler blowout compressor to drain the water. Even after turning the water off at the main valve, there will be water leftover from previous use. Getting this water out is essential to keeping your system functioning season after season.

Electric vs Gas: Which is Right for your Sprinkling System?

You can choose an air compressor for sprinkler blowout that is powered by an electric or a gas motor. Both options offer advantages and disadvantages.

Electric motors may limit your project because you need to have a 120-volt electricity source nearby. Blowing out sprinkler systems involves a lot of water spraying everywhere. Take precautions before using an air compressor for blowing out water lines that have an electric motor.

Gas motors are not limited by the length of their extension cord. You can bring a gas-powered motor almost anywhere on your property.

The right air compressor for a sprinkler blowout system may be one with gas power because it is less dangerous and offers more mobility.
