Prepare, Protect, Prevail: Rain and Freeze Sensors in Action

rain and freeze sensors

That magical time of the year is upon us. As we prepare for another season of glistening snow and beautiful white treetops, it’s time to prepare our outdoor properties for the freezing temperatures. According to the Old Farmer’s Almanac, November 20 is the first frost date for Dallas, Texas. Much like preparing your home for the chilly season, your commercial property’s irrigation system deserves winter prep. 

Texas winters tend to bring about sudden and severe weather conditions, sometimes catching us off guard. It is for this reason that the state regulations require the installation and proper functioning of rain and freeze sensors, failure to which could result in substantial liability in the event of an ice storm or severe rain.

We are committed to providing our clients with essential information that helps them make informed decisions about landscaping and property maintenance. In this blog, we discuss how rain and freeze sensors work and how best to protect your irrigation system before winter arrives. 

What are Rain and Freeze Sensors, and How Do They Work?

Rain and freeze sensors operate under a simple logic: Operating an irrigation system only when necessary. They detect rain and freezing temperatures and prevent the irrigation system from running when any of these events occur. 

This often involves a cup or disk that activates a switch once it reaches a certain weight. The added weight prompts the system to shut off the water supply. Additionally, it incorporates thermometers to monitor temperature levels.

Why It Matters?

When water freezes, it expands. This is dangerous for your irrigation system as the frozen water will burst pipes and horses and ultimately damage your sprinklers. Furthermore, these sensors eliminate runoff that can cause dangerous icing on a road or sidewalk. Besides being a worthy safety precaution, these devices help you save water and protect your greenery from the harmful effects of overwatering or damage.

Sensor Placement Counts

Even the most effective rain sensor is useless if poorly installed. Location plays a crucial role in this respect. This means not putting a sensor near anything that gives off ambient temperature, such as heating/A/C units, boiler rooms, or areas obstructed by trees or other landscape objects.

The idea is to position the sensor to expose it to the elements without obstruction. Keep in mind extreme variations, such as direct sunlight and shaded areas, can lead to inaccurate readings. 

What To Do in the Event of a Freeze Event 

In the event of freezing weather, it’s essential to shut off the main water valve of your irrigation system. Doing so stops the main water supply, preventing water from entering and freezing within the system. Remember, it’s your responsibility to take measures to prevent your system from operating during freezing conditions.

We can’t guarantee that your rain/freeze sensors will remain operational at all times. That’s why we advise conducting regular visual inspections to ensure they function as they should. 

Stay Ahead with Timely Maintenance

As a responsible property owner, regularly testing your sensors is a proactive measure that guarantees the protection of your landscaping investment. For this reason, we recommend scheduling your inspection well in advance so you can rest easy knowing your system is well-prepared for the season’s freezing temperatures.
