January Sprinkler System Tips
January Watering Restrictions
At the direction of the North Texas Municipal Water District (NTMWD), many cities in our service area have implemented Seasonal Stage 3 watering restrictions (effective through March 31, 2014), consisting of watering landscaping once every two weeks. Please check your city’s website to determine watering details and schedule.
Protecting a Sprinkler System during Freezing Temperatures
Fortunately for cities in our service area in Dallas, Collin and Denton counties, the month of January does not generally include extreme temperatures or weather, and surface soil typically does not freeze. Although many homeowners have turned off their sprinkler systems as most vegetation goes into its dormant stage, there are several things that homeowners can do, or keep in mind, to help to protect their sprinkler system, should the northeast Texas area be exposed to below-freezing temperatures.
- Keep an eye on the weather, especially the long-range forecast. This will help homeowners to be prepared for cold weather.
- Any aboveground equipment will need insulation installed to prevent freezing during sub-zero temperatures. (Wrap the aboveground equipment with foam or fiberglass insulation, extending down underground to below the typical freezing depth.)
- Generally, draining the pipes of a sprinkler system in the winter is not necessary, as the soil provides sufficient insulation to prevent water from freezing.
- During freezing temperatures that last longer than a couple of days, insulation may not work well as the cold air has time to penetrate through the insulation, cooling the pipes and equipment and water inside. In areas where freezing weather lasts longer than overnight (rare in our area), but you still need to keep the irrigation system operational, it is a good idea to install electric pipe heaters on backflow prevention devices and aboveground valves.
Equip the sprinkler system with a Rain and Freeze Sensor, a wireless sensor that is mounted to your house and communicates with your sprinkler system’s controller. When the sensor becomes too wet (rain) or too cold (freezing temperatures), it will not allow the sprinkler system to water.
