Test the Drainage System with a Golf Ball

What happens here

To confirm the proper function and slope of the newly installed drainage pipe, perform a golf ball test. Place a golf ball into the highest point of the perforated pipe system. If the system is correctly graded, the golf ball should roll smoothly through all the pipe sections and exit at the pop-up emitter without stopping. The video shows workers dropping a golf ball at the start of the system and observing its travel down the pipe, confirming successful installation and grading.

Goal: Verify proper water flow and system grading.
