ULTIMATE French Drain Pipe Water Race Test (Results Will Surprise You!)

[@JCJC650]

All the pipes will be at max flow if you scale this up. S40 is harder for contractors to install incorrectly. Bad contractors install parts of flex pipe in dips causing drainage issues. The flex pipe is superior if installed perfectly.

Why blue one stick out further & end so much lower than the others?

To show flow out of the holes in the last test

Yes it was just to show the final double plug test. If anything this would have been an advantage to the others because high octane blue would have had to move the water further. It bent down because it was longer. This didn’t give an advantage, high octane drops the water level much faster than any of the competitors

Much of the problems are from bad installation practices, agreed. Same with PVC, many install them on a highest and lowest point of gravity and don’t bed the pipe with correct slope. The same happens, weight of the dirt pushes the pipe flat or to have bellies. This not only causes water restriction and debris build up, but also limits the air flow to break siphon. Thanks for the comment!
