DIY EDUCTORS

[Anonymous]

is it me or does any one else think that all we are doing is narrowing the output thereby increasing pressure. can we measure it some how?

eductors actually increase water flow (gph) through a regular pipe opening of a same diameter/source pump

it works very much like a venturi-instead of air being drawn into a moving column of water, water gets drawn into a moving column of water

they actually increase flow inside the tank by pulling water through the holes then pumping it back out. you can see this effect in the video link that was posted. IMO this is a great idea to increase overall circulation inside the tank.
