Flow Bench Test Results

[kd4crs]

Sorry I have been absent, our family is on vacation this week and have not been monitoring the forums. First, thanks for testing the various setups and posting the results. I wondered about the flexibility of the PVC downspout adapter and you confirmed what I suspected, that it might bow inward with high flow. That is not good for airflow. I will see if there is anything else that can be substituted or if the downspout adapter can be modified, perhaps by shortening the length of the leading edge will reduce or eliminated the bowing effect. The lip of the downspout adapter is what actually holds the unit in place so cutting it off entirely would not work. Further research will be needed. In the meantime the best alternative is the reduced straight PVC/ABS pipe into the fender. Thanks again for the testing and the results.
