Why do you need an air compressor to blow out sprinkler systems?

Most people don’t consider winterizing a sprinkler system as a part of their home maintenance. The importance of winterizing a lawn irrigation system can’t be ignored. During the winter months, water tends to freeze. As a result, the water pipeline begins to burst or crack. And, this is the main reason why you need an air compressor to blow out sprinkler systems effectively.

It is always good to inspect your sprinkler system during the winter season. And, use the time to replace or repair the entire system. However, installing a new sprinkler system is not a cost-effective solution. Rather, you can buy a new air compressor. Also, you can work with the equipment by yourself and don’t need a professional to handle the same.

How to choose the right air compressor?

With lots of options available on the market, it is challenging to find out the right air compressor for your sprinkler system. However, you should buy a heavy-duty and portable model. And, that will fulfill your needs. Here are some factors that you should consider when buying an air compressor.

  • Tank size

It is unwise to choose a large tank that comes along with smaller pipes. Hence, make sure that the tank size is prominent and it has a long pipe. Smaller compressors might perform a great job if the equipment has big lines. Therefore, before narrowing down your choice for a model, take enough time to research the tank and its features.

  • Kinds of motor

Air compressors come with lots of motor types and each of them has its benefits. However, the most commonly used is the single-phase induction motor system. It is effective and works wonders for many tasks. But if you are looking for that extra power, a dual-motor system should be your choice.

  • Horsepower

PSI is the unit of measurement used to denote the horsepower of air compressors. Hence, the more PSI, the more it gets easier to blow out sprinklers during the winter season. While PSI mostly depends on the size of the pipes, 60 to 90 PSI should be enough for an air compressor.

  • Portability

It is wise to look out for an air compressor that is easy to transport from one place to another. That way, you aren’t stuck with using the equipment within a certain area of your farm or home. So, try to look out for lightweight models that are easy to move around. In short, a model with transportation wheels is what you need to find out.

  • Accessibility

You should look out for an air compressor that has a large outlet and inlet. That way, you can attach tools and accessories with ease. Also, you want a device where you can easily use the air pressure gauges to know how much air is left in the tank. Besides, it should have indicator lights. As a result, you can know when to refill the tank.

  • Decibel rating

Avoid buying an air compressor that produces a loud noise. And, this becomes important if you are living in residential areas. A low decibel rating means that the equipment won’t be producing a lot of noise. Furthermore, quiet units are a better option for extended periods. And, it saves your ears from damage as well.

Useful tips on how to blow out a sprinkler system with an air compressor:

Knowing about the compressor specs is critical before you perform a sprinkler blowout. However, implementing the project effectively is equally important. Here are some useful tips that you can follow for a successful sprinkler blowout using an air compressor.

  • Getting started

Before you get started with the process, prepare the whole sprinkler system for the blowout. Shut down the main water supply that runs through the sprinkler system. Moreover, close the additional valves that you can find on the backflow preventer. As such, the compressed air won’t flow through the backflow.

  • Make the connection

After you are done preparing the system, it’s time to connect the compressor to the blowout port located on the sprinkler line. However, you may need an additional adaptor if the water line doesn’t have an air compressor fitting. While some models come with this piece, they are hard to find at local hardware stores. Moreover, the adaptors include couplings that secure the connection. And, they are readily available as well.

  • Engage the compressor

After charging the air compressor, apply air to the sprinklers slowly. Make sure that it doesn’t exceed the recommended PSI for the sprinkler piping. Also, you can disengage the blowout port valve slowly. Wear suitable eye gear when engaging the compressor. When you are performing a complete blowout, the compressor is likely to target different zones of the sprinkler system.

  • Before disconnecting the compressor

When you are blowing out sprinklers in a certain zone, ensure that you are engaging the compressor for a specific amount of time. As such, it will clear the water out of the section. And, you can tell that by watching the sprinkler heads. Once you notice air escaping through the sprinkler heads, the line has no water. In general, it takes about 3 to 5 minutes per zone.
