Drain pipe is lousy for drainage. Use HydroBlox instead. 

If nobody sells it you know it's good.

over time, won't the hydroblox clog with dirt and make it unusable?

It's been 3 years since you posted the video. What are the results? Are the Hydroblox effective for your application?

Hrdroblox are solid plastic and don't soak up anything

😂🤣😅😁

I wasted $6K on this snake oil. I've got install videos and after 3 yrs, I've got the disposoal videos. I calledd the guy in the California area who worked the intstall and he said let me talk tto the installer (his son) and then he ghosted me. Hydrobolox are a scam.
