Do I need to drain my sprinkler system for winter?
It’s not enough just to keep water from flowing into the system; you also need to drain out the water that’s already in there. This is the biggest and most time-consuming step in the process, but it’s absolutely vital. There are three main methods of drainage depending on what type of sprinkler system you have.
How do I drain my sprinkler system for winter?
If you have manual drain irrigation, follow these steps: Shut off the water supply to the system. Then, look for the manual valves at the ends and low points of the piping. Open all the valves and drain the water from the system. Make sure you also drain the backflow device.
How do I know if my sprinkler system is self draining?
Depending on the type of drain valve your system utilizes, draining could be truly automatic, or it could be manual, requiring that you pull a few levers to get things moving. One way to tell if your system is manual-draining is if your sprinkler heads have check valves on them.
Should I drain my sprinkler system?
To avoid any possibility of damage, sprinkler lines need to be drained prior to temperatures dipping below 32 degrees Fahrenheit. Failing to winterize a sprinkler system before a hard freeze (air temperature is below 0 degrees Fahrenheit) can lead to expensive and time-consuming repair costs.
Should sprinkler valves be open or closed?
Make sure the sprinkler valve is closed, unless it’s the valve farthest from the main water source. You’ll want to leave this valve open and remove the sprinkler nozzle to allow air to escape when you turn on the water.
How cold is too cold for sprinklers?
While you may be eager to get your lawn back to its pristine green state, it is important to remember that temperatures of 32 degrees Fahrenheit or lower put your sprinkler system at risk of freezing.
How do I turn off and drain my sprinkler system?
Automatic Drain Valves Turn off the water supply by closing the main valve to the sprinkler system. As pressure inside the system falls, it will drain water automatically. Open the drain cap between the main valve and the backflow device. Lift each sprinkler head to drain out any residual water.
What position should sprinkler valves be in?
There should be two, usually blue handled, ball valves (one on the side closest to the house and one on the side going to the irrigation system). Both should start in the closed position (perpendicular to the pipe).
How do I know if my sprinkler valves are open?
Turning it to the left lifts an internal gate that releases water incrementally as it turns. The gate lifts entirely when the handle is turned fully counterclockwise. If the handle will turn no farther counterclockwise, the valve is open.
What is sprinkler drain pipe?
The main drain is located at the fire sprinkler system riser. Its purpose is to discharge water outside and away from your building or to a connection that can manage the flow of the drain and also to measure the water pressure in the system.
What is auto drain in sprinkler system?
Automatic sprinkler drains, when installed correctly have eliminated the need to blow out your sprinkler system for the winter. Essentially the automatic drains “blow out” the lines every time the water is turned off. Install drains at all low points in each line.
Should you water grass before a freeze?
You’ll need to water early in the day to avoid creating a sopping wet mess right before temperatures start dropping. When watering, try to do it without getting any of the actual foliage wet. Wet leaves will form frost that kills faster than just the cold air alone.
At what temp should I not water grass?
Any temperature below 40℉ is too cold to use sprinklers to water your lawn. Although air temperatures are still above freezing, water droplets clinging to grass blades will be exposed to wind chill or colder nighttime temperatures, which may freeze them solid. This can result in brittle, frozen grass.
What is the best time to water your lawn?
Watering in the morning (before 10 a.m.) is the best time for your lawn; it’s cooler and winds tend to be calmer so water can soak into the soil and be absorbed by the grass roots before it can evaporate.
What is auto drain valve?
Automatic drain valves remove mixtures of water and compressor lubricants from compressed air systems. An automatic drain valve eliminates the need for a maintenance worker to patrol the plant, manually dumping liquid from the air system.
How do I know if my sprinkler system has a master valve?
Start at that sprinkler and try to find the valve nearby. The cheapest and easiest way to find buried irrigation valves is often to probe the soil with a thin rod, such as a long screwdriver. Often you can estimate the rough location of the irrigation valve, then find a buried valve box by probing the ground.
What causes a sprinkler valve to not shut off?
If your irrigation system does not turn off, you need to isolate the problem. This starts by checking the main water line and the controller. If those are working, then you need to locate the valves and check to see whether they are dirty, the diaphragm is torn, or the solenoid is broken.
