Water pressure changes have the potential to wreak havoc on an irrigation system. While water pressure issues may come unexpectedly, it is worth knowing that a number of things can influence sprinkler irrigation pressure. Some are easier to detect and repair above ground, whilst others may necessitate more costly repairs if found below. With that being said, it is crucial to keep yourself informed.

Read on to learn more about the common pressure issues of an irrigation system.

The Failure of the Pop-up Sprinkler Head

When water pressure is provided, sprinkler heads rise into the air. The amount of water pressure in the system decreases as irrigation pipes break and sprinkler wiper seals wear out. 

To resolve the issue, turn on the station and then raise the jammed riser stem of the head. If the sprinkler system can be easily pulled up, hydraulics may be to blame. If the head cannot be raised, both the riser seal and the stem should be changed.

The Strange Misting

Sprinklers mist and blow away water when irrigation pressure fluctuates, preventing it from reaching the grass and landscaping at the optimal rate to encourage healthy plant growth. This is required to maintain lawns and gardens looking their best. Misting occurs when debris obstructs the nozzles and heads. 

Remove debris from sprinkler nozzles to repair. If the misting persists even after the nozzles have been fully cleaned, there may be a problem with the irrigation pressure at a lower level.

The Pressure Imbalance in Drippers

When there is uneven or imbalanced pressure in a drip irrigation system, you must first check to ensure that the system has not run for any longer than its maximum time or flow capacity. Afterward, clean the filters. 

Dripper should be replaced or completely cleaned. It is possible to reset uneven emitters by placing a finger over the drip exit and holding it there for a few seconds while the water is running.

The Water Line Breakage

If an underground water main bursts, an irrigation system would be rendered worthless. This is what will happen if you accidentally break a water line while putting up fence posts or garden stakes. If an underground water main bursts or leaks, it could cause soil depressions or excessively moist lawns.

Low water pressure reduces the irrigation system’s efficacy, resulting in dry and brown sections of the landscape. The irrigation system may be damaged if the water pressure is too high. Since of the high water pressure, irrigation is wasted because the water mists out of the nozzle and is carried away by the wind.


Water pressure in irrigation systems must be controlled in order to keep lawns and landscapes healthy. Based on PSI readings from a Pressure Sensor, the Baseline Pressure biCoder can start, halt, or pause the programming of an irrigation system. In addition, the Pressure biCoder can turn off pumps or master valves in response to high or low-pressure warnings. Through these sensors, you can act fast and adjust the water pressure of your irrigation system.

The most common problem with sprinkler systems is low water pressure. Controlling the irrigation pressure of a sprinkler system is essential for maintaining a lush and healthy environment. Thankfully, today’s pressure sensors handle the job for you. Simply make sure you keep this guide in mind as you deal with the common pressure issues of an irrigation system.
