What can cause obstructions in a sprinkler system?

Obstructions in a sprinkler system are primarily caused by debris accumulation. Over time, materials such as dirt, leaves, or sediment can build up in the pipes and sprinkler heads. This accumulation can hinder the flow of water, leading to inadequate coverage and reduced efficacy of the sprinkler system in maintaining the intended irrigation or fire protection functions. Proper maintenance, including regular cleaning and inspections, is essential to mitigate the risk of obstructions from debris.

High water pressure, while it can pose other issues such as causing leaks or damage to components, does not contribute to blockage in a system. Frequent inspections help identify and prevent obstructions rather than cause them. Reduced temperature can affect water flow and valve operation but does not directly cause obstructions in the system itself.
