Sprinkler System Basics from Lee Engineering – Dallas, Fort Worth
Despite the recent erratic temperature fluctuations, Dallas area homeowners are beginning to plan for warmer weather. Before planting new landscaping this spring, it is wise to perform a check-up on your irrigation. Use the following information as a guideline to prep your irrigation system for summer’s increase in water demands.
Types of Sprinkler Heads
There are many variations of sprinkler head designs. Depending on your specific needs, your irrigation system may have a combination of the following sprinkler heads:
- Fixed spray heads
- Rotary spray heads
- Pop-up sprinkler heads
- Multiple stream spray heads
Fixed Sprinkler Spray Head
This type of nozzle produces a tight, constant fan of water. Fixed sprinkler heads can be stationary or pop-up and are typically used for smaller lawns, shrubs, and near ground cover.
Rotating Irrigation Head
Rotary heads generally have one powerful stream of water that rotates in a full or partial circle to irrigate the surrounding turf. These spray nozzles are commonly found in medium to large yards and are often used on side lawns. Most rotary heads are also pop-up heads.
Pop-up Sprinkler Head
Nowadays, most sprinkler systems are designed with pop-up heads that retract at the end of the watering cycle. Even so, spray heads are commonly damaged by lawnmower blades or other landscaping tools. These easily concealed heads provide a low, even distribution of water for all size lawns and gardens.
Multiple Stream Sprinkler Head
This spray head is similar to the old-school sprinklers that many of us(in the South) played in during our childhood on scorching hot summer days. The only difference is multiple stream sprinkler heads aren’t portable. Instead of hooking up to the water hose, these rotating sprays connect to underground irrigation pipes.
You may notice these types of sprinkler heads on sloping or uneven landscapes. Our Licensed Irrigators usually recommend replacing multiple stream heads with a more efficient, pressure-regulating head to reduce irrigation water waste.
Broken Sprinkler Heads
Before running your sprinkler system, perform a visual inspection for broken heads. Since most irrigation systems are scheduled to run in the wee morning hours, damaged sprinkler heads often go unnoticed. In fact, many homeowners aren’t aware of the issue until they get an outrageous water bill in the mail.
To replace damaged heads, simply unscrew the head(also called a stem) and bring it to your local hardware store for a replacement.
Misaligned Spray Patterns
Systematically run each zone, making note of obstructed and misaligned spray patterns. Prevent dry, dead patches in your landscaping by trimming back any shrubs that interfere with spray heads. Adjust spray heads to avoid excessive over-spray on sidewalks, driveways, and areas that are prone to rot(such as window seals).
Adjusting Your Sprinkler Heads
Depending on the manufacturer, you will need a couple of tools to adjust the direction of spray on your rotor heads. Here are a few helpful tutorial videos for common brands:
