Overview of Underground Sprinklers
The sprinkler heads work on a pressure system. When the water goes through the pipe, it pushes them up above the ground. When the water pressure stops, they retract back down to ground level.
Operating Automatic Underground Sprinkling Systems
Flier’s Automatic underground sprinkling systems operate with a programmable controller. You can schedule when and where various portions of your lawn will be watered. Some controllers have multi-programs to water turf and landscape areas on different schedules.
Installation and Winterization
-
How deep are underground sprinklers buried?
- Dig trenches usually 6 to 12 inches deep, depending on your area’s freeze cycles and frost severity. The trench must allow the sprinklers to retract underground to prevent breakage from lawn machines.
-
Do underground sprinklers need to be blown out?
- To minimize the risk of freeze damage, you’ll need to winterize your irrigation system. In areas where winterization is mandatory, irrigation systems are installed using one of three types of water removal: manual drain, auto drain, or blowout.
Winterize Your Sprinkler System
A good rule of thumb is to have your sprinkler system winterized in early fall, and ensure that your watering system is drained and blown out at least one week prior to the season’s first freeze. It is important to remember that temperatures of 32 degrees Fahrenheit or lower put your sprinkler system at risk of freezing.
Importance of Sprinkler Blowout Services
Weed Pro provides professional sprinkler blowout services. Sprinkler blowout services are vital to the health of your underground sprinkler system. All of those sprinkler heads are connected with plastic water-lines, and those lines are only 6 to 12 inches underground. In Saskatchewan, we have an extreme climate, and the ground can freeze as far down as 6 or 7 feet. Water freezes at 0° Celsius, when water freezes, it turns to ice and expands.
