Hi Takadi,

I don't really understand what your asking. What are you ultimately trying to do or achieve? What is the purpose of the device? Aloha.

When It Rains, It Drains. When It Shines, It Rewinds. The RAINDRAIN rain removal system is that simple in operation. The force of the rain traveling to the downspout will start the RAINDRAIN water extension process through the perforated holes. It rains and it will automatically unroll, the rain stops and it will automatically rewind. Simple process, vital protection. Exclusively designed and engineered with a built-in flush system.

hahah that's funny, I went to a hardware store and bought this exact same thing the other day. It works okay I guess. Alot of the water still just exits through the first two or three holes in the tubing and floods certain spots but it was better than before

WJB,

Ah ha, wow, now I get it. Good call. Aloha
