How to winterize sprinkler system Rain Bird

You cannot keep the sprinkler system wide-open on the ground during the freezing winter. If you live in an area where the temperature tends to go below zero during the winter, winterization to your sprinkler system becomes a must.

If you have installed a Rain Bird sprinkler system on your lawn, this article will help you winterize your sprinkler system with decent proficiency. We will try to be specific enough with our process so that you don't become bored going through the process.

This simple DIY process does not require any professional knowledge. Everyone with a primary knowledge of pop up sprinkler systems and components will be able to complete the process with proper guidelines.

And this article is going to be the guideline to winterize your Rain Bird sprinkler system-

How to winterize sprinkler system Rain Bird

There are three different methods you may follow to winterize your Rain Bird sprinkler system. The process depends according to the type of system you have. Some draining systems require you to use advanced tools, whereas many others may allow you to complete the draining without any additional tools. The three processes we will follow to winterize our sprinkler system are-

  • Manual draining.
  • Automatic Draining.
  • Blow out Draining.

Before we start discussing each and every step, here are some of the precautions everyone should maintain to winterize a sprinkler system-

Precautions

  • The first precautionary step you need to take to winterize any sprinkler system is turning off the water supply. C’mon! You cannot keep the water flow intact while winterizing the sprinkler system.
  •  Some sprinkler systems do use a water timer to control the water flow. If you are using such a sprinkler system, turn off the time before starting the winterization process.
  • Use eye protection goggles to protect your eyes from physical damage. If you remove the drain cap or pressure valve before removing the pressure, it can cause serious damage to your eye.

Step one: Manual draining

  • The first step of draining the water manually is opening the control valve of the sprinkler system from the timer. You can do the task manually or electrically. Removing the control valve will allow the sprinkler system to reduce pressure on the mainline.
  • While opening the valve, you need to be super careful. Do not try to open the valve too fast. It may cause the system to drain the pressure at a rapid speed, making the system vulnerable.
  • You need to repeat the same process again and again according to the number of all manual drives.

Step two: Automatic draining

  • If your sprinkler system has an automatic drain valve, you have to face less trouble to complete the process.
  •  You just need to shut off the drain valves to let the system do the draining on itself.
  • Once the drain valve is off, the automatic function will remove water from the system without any interventions.

Step three: Blow out draining

You can complete these step by following two different methods. The first step is doing the process by activating the sprinkler control valves from the timer. On the other hand, the next step is b activating the valves manually.  Here are the procedures-

Blow out draining through activating the control valves from the timer

  • You will require a compressor hose to the work.
  • First of all, you will need to relieve the air pressure by activating a circuit from the timer.  We recommend using the furthest distance to activate the circuit.
  • After that, install the compressor hose to the blowout adapter.
  • You need to reduce the psi level of the pressure regulating valve. The Rain Bird recommends you set the pressure to 50psi.
  • Now turn on the compressor to start the blowing method. You should not blow any circuit for more than 2 minutes. It can deteriorate the condition.
  • Remember that turning off the timer during this process may cause a blunder. Be very specific about your process.
  • You may drain a circuit twice to ensure a perfect blowout. 
  • Once you have done blowing out all the zones, keep one zone on before shutting down the compressor.
  • After that, remove the compressor from the system and turn off the timer to keep your sprinkler system in hibernation.

Blow out draining by activating the valves manually

  • You need to relieve the water pressure from the system before attaching the compressor hose. Open the manual shutoff handle slowly from any one of the control valves. After that, connect the compression hose to the blow out adapter. 
  • After that, set the pressure to 50psi to ensure safe water draining.
  • You need to do the blowing out one by one. Turn on the exact station you want to blow out first.
  • The condition remains safe for this section, too. You should not drain a circuit for more than two minutes.
  • Once you have done winterizing the first station, move to the second one.  Once you have moved to the next station, turn off the previous circuit properly.
  • After draining all the compartments, turn the compression hose off to remove it from the system.

Final words

Winterization of the sprinkler system prevents damage and deterioration during the winter. If you prefer irrigation on your lawn or yards, a sprinkler system always comes as a handy tool. Winter is a barren month, forcing everyone to remain in hibernation. If you don't ensure good protection to your sprinkler system during winter, it would not provide the same functionality during the next spring. Doing the winterization process is a simple job anyone can do with proper knowledge. You just need the proper instruction and guidelines to complete the process.
