Your irrigation system is responsible for delivering water to your grass and plants in North Carolina. If you notice that it has low water pressure and is not as efficient at delivering water as you want it to be, it could be a problem for your vegetation's health. It's important to explore what is causing this issue. Various reasons can cause low water pressure within your irrigation system, like a broken pipe, a malfunctioning backflow preventer valve, clogged sprinkler heads, an obstruction in the lines, and the main water valve not being opened fully. When this happens, it's best to hire irrigation professionals to inspect your system and diagnose it correctly. They'll be able to perform the necessary repairs to improve the water pressure and ensure your irrigation system delivers water efficiently.

Common Reasons For Your Irrigation System's Low Water Pressure

If your irrigation system has low water pressure, the primary casualty will be your grass and plants because they won't receive the right amount of water they need to thrive. Various reasons could cause this issue. Some reasons could be from parts of the system located above ground, which can be easier to detect and repair, but it can also be from a part below the ground. Here are common reasons for your irrigation system's low water pressure:

  • Broken pipe: A broken irrigation pipe means water is leaking somewhere and not reaching the sprinkler heads. It is usually the result of digging in the yard or putting up garden stakes and can be identified by unusually wet areas on your lawn. These wet areas can also usually indicate where the leak is.
  • Malfunctioning backflow preventer valve: Your irrigation system's backflow preventer valve ensures water flows in the right direction. If it is malfunctioning, it will decrease the water pressure in your irrigation system. Improper installation, not fully opening the valve, and a damaged O-ring are common causes of a malfunctioning backflow preventer valve.
  • Clogged sprinkler heads: Sometimes, the low water pressure is simply caused by a blockage on the sprinkler head. When the sprinkler head is clogged, water will not be able to flow properly! This issue can be caused by the natural buildup of algae, calcium, and bacterial slime.
  • Partially opened main water valve: The main water valve provides water to your home or business and is connected to your irrigation system. Keeping this valve fully opened ensures good water pressure for your irrigation system! Sometimes, the main water valve cannot be opened fully because of the buildup of foreign material, or it has gotten stuck if you have not used your irrigation system for a while.
  • Obstruction in the lines: An obstruction in the lines can cause the water to not flow properly, resulting in low water pressure. Obstructions are usually caused by the sprawling roots of nearby trees and shrubs.
