Winter is the time of the year when people take precautionary measures to protect their outdoor equipment or property from the damaging effects of harsh weather. This is particularly true for those who are residing in the northern area where the weather is significantly colder than other parts of the country.
Some outdoor equipment is placed indoors or in the garage to protect them from the harmful effects of freezing weather. But some stuff cannot be detached and must remain in places such as lawn sprinkler systems and drip irrigation for landscapes. Both of them must be protected against freezing. But is it possible if they must remain exposed to strong weather conditions?
In this article, we will be focusing on the lawn sprinkler system and the most common ways to protect it from any cold weather condition.
Read on the following procedures that you can do by yourself on how to blow out your sprinkler system:
- Find the main switch button of your water sprinkler system and turn it off. This is to ensure that the water will no longer flow in the sprinkler. You may find the master shut off valve in the basement, utility room, or outdoor shed. The location varies depending on the type of system you have and how it was built.
- Drain the water from the sprinkler system, manually. Open the hose bib to lessen the pressure flowing through your system’s pipes. Drain the water running from the pipers in a large bucket. Just keep in mind that the water will shoot because of the pressure in the pipes, and you are most likely to get wet.
- Buy an air compressor from any of your local hardware stores, or if you don’t want to buy one, you can rent it from your local equipment rental yard. Charge the compressor to 60 pounds per square inch, as experts recommended. Most compressors have the maximum capacity to charge up to 120 pounds per square inch. But don’t charge your air compressor at that level, as too much pressure can cause damage to your sprinkler system.
- Once your compressor is sufficiently charged, connect it to the hose bib. Make sure that the compressor is switched off while doing this. When attaching your compressor to the hose bib, make sure to get creative in securing a seal because most of the time, the air compressor and the hose bib’s fittings don’t exactly match.
- Switch on the air compressor and empty the hoses. Begin with the farthest area from you and work your way to the nearest. Keep the air compressor working for at least two minutes in every zone. The water will sprinkle from the system as you do this. You’re done with the process once you’re finished with the nearest zone.
- Disconnect the air compressor from the hose bib and keep everything in proper places.
This can be a simple job if you are used to taking care of lawns and sprinkler systems. If this is your first time doing this task, be careful with handling the equipment like an air compressor. Always read the manual instructions before operating.
