How To Winterize Lawn Sprinkler System

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.

Can I winterize my sprinkler system myself?

You can winterize a sprinkler system without an air compressor if all of your irrigation lines are buried at a slight downhill slope. Simply shut off the main water supply to your system and open the drain valves at the end of each zone.

How do I protect my sprinkler system from freezing?

Shut off the water supply to the irrigation system. The main shut off valve for your irrigation system needs to be protected against freezing. Make sure it is wrapped with insulation (foam insulation tape and a plastic bag) to protect it from harsh winter temperatures and prevent it from freezing.

Do I need to winterize my sprinkler system?

So, if you have a lawn sprinkler, you need to winterize it before the temperatures plunge to the freezing mark. If you forget to winterize your sprinklers, you run the risk that water will freeze in the irrigation valves, pipes and sprinkler heads.

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 much psi do I need to winterize my sprinkler system?

Air pressure must not exceed 50 pounds per square inch (psi) during the blow out procedure. A pressure-regulating valve must be used to avoid over pressurization of the system. Air volume should be high and air pressure low.

How do I bleed my sprinkler system?

Bleed your sprinkler system to avoid any potential problems. Bleeding, or “winterizing” your home’s sprinkler system is one way to protect your sprinkler system from freezing during winter. An easy way to do this is by draining the pipes and then blowing it out to dry with an air compressor.

When should I blowout my sprinklers?

A good rule of thumb is to have your sprinkler system winterized in early fall, but we recommend keeping an eye on the weather, and ensure that your watering system is drained and blown out at least one week prior to the seasons first freeze.

How much does sprinkler blowout cost?

Typical costs: Hiring a landscaping or sprinkler company to winterize/blow out a sprinkler system can cost $30-$160 or more, and typically costs about $55-$85 for an average home, depending on the number of irrigation zones in the system, the local cost of living and the month the work is done.

How do I stop my sprinkler pipes from freezing?

To keep the water inside the pipes of a wet fire sprinkler system from freezing in areas where the temperature may drop below 50 degrees, an antifreeze loop is added. By adding antifreeze to the water in the fire sprinkler pipes, the freezing point is much lower, reducing the risk of the pipes freezing.

Can pipes freeze at 27 degrees?

Pipes can freeze at 32 degrees or below, but it will take a sustained period of time for this to happen. And, generally speaking, the temperature needs to be well below 32 for at least that length of time before freezing becomes likely.

Should I water my grass after a freeze?

After a frost, keep perennial turfgrass hydrated. Most grass needs 1 inch of water weekly, including rainfall. Continue watering the grass as it enters dormancy when temperatures cool, but never allow water to puddle, which cuts off the roots’ access to air and light.

Is it too cold to water grass at 55?

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.

How often should I water lawn in winter?

Watering once or twice a month is usually enough to keep your lawn moist throughout the winter. Check in on it weekly and look for signs of stress and wilt. See if the grass bounces back after being walked on. Some stress is good for your lawn’s root development, but make sure it doesn’t get too stressed.

What month winterize sprinklers?

October 1st thru December 15th (temperature permitting) is the optimal time window to winterize your irrigation system! While the weather plays quite a big role each year in determining when clients want to winterize their system, we strongly recommend winterizing your system during this time frame.

How do I maintain my sprinkler system?

How To Maintain Your Irrigation System Check Your Water Pressure. Check For Any Missing Or Broken Sprinkler Heads. Adjust Sprinkler Heads So That They Are At The Right Angles. Change Control Timers To Meet Seasonal Plant Needs. Match Runtime To Exposure.

How many sprinkler heads can be on one zone?

At different pressures, the sprinkler head and nozzle will consume different amounts of water. For example, at 35 pounds per square inch (PSI) the 5000 Series Rotor using the 3.0 nozzle will use 3.11 gallons per minute (GPM). If your home’s water capacity was 10 GPM, you could place 3 heads per zone.
