In regions where low temperatures during winter is expected, the yearly cycle of blowouts is necessary. A homeowner need to be knowledgeable about winterizing an irrigation system and about the different type of sprinkler system installed. Good maintenance and care before winter arrives will prevent all the trouble over damages seals, pipe ruptures and cracked valves. Damages due to an inappropriate sprinkler winterization are costly to fix and will need a large area of the landscape to be excavated to find and fix the problem. Due the possible risk involved with blowouts, it’s better to let Sprinkler Bros specialists handle it.
Most irrigation systems have either an automatic or manual drain valve and have underground sloping pipes. They are used to let gravity drain the water out of the pipes. But over time, the piping in sprinkler systems will shift and sink making the drain valves useless. They will eventually cause water to accumulate inside the pipes where the ground has shifted. Any water still remaining in the pipes will freeze during low temperatures and cause severe pipe ruptures and damaged sprinkler heads.
Here at Sprinkler Bros, we guarantee the efficiency of our sprinkler systems and that means that all the pipes and valves are not buried deep enough under the ground for protection against cold temperatures. To ensure proper sprinkler winterization and to remove all the water from the irrigation system, a proper blowout must be done using compressed air. We perform the following steps to winterize a sprinkler system.
1. We will first turn off the water both inside and outside to make sure that your main controller and sprinkler system are shut off correctly.
2. Compressed air is the ideal way to make sure that all the water is removed from the valves and the pipes. We will use an air compressor to blow out each section of your sprinkler system.
3. If we find any problems that need repairs, then we will recommend either temporary repairs to be completed until the spring or more immediate “fixes”.
4. After we disconnect the air compressor, we will ensure that all the backflow prevention valves are open halfway to the open position during winter.
5. Last step would be to adjust the controller to operate in hibernation mode meaning minimum cycle to ensure the solenoid valves from becoming stuck in the closed or open positions.
