Thank You I was having trouble with it i had a similiar design in mind but could not get the name or any specs. you would not believe how troubling it is to look for "ways to stop a whirlpool" or "stopping a vortex" etc. Thank You. The previous one that was tested did not sit in the drain as one...
I am looking for an Idea as to how to possibly reduce or eliminate a whirlpool in a cylindrical tank that currently is driaining too slow due to this problem. (in the 700-1000 gallon batch tank size range)
