What happens when a pipe is partially blocked?

  • During a hot summer season, one of the pipes (which is partially blocked by rust) is unable to keep up with the water needs of of the area that it supplies.
  • The area supplied by the partially blocked pipe turns brown, but is still alive. Restoration of full water supply or a decrease in water need (less scorching weather) will make the grass turn green again.
