Foam Fractionator question
Ethan,
Good morning. I am in the process of building the foam fractionator that you highlighted in the 2006 thread. But I have a question, please. My 18,000 gal pond is above ground by a few inches and the "wall" around the pond is even higher, of course. So, I either need to raise the bottom of the foam fractionator about 24 inches, or run the 2" output up and over the wall of the pond.
It seems to me that the purpose of the 2" ball valve at the output is to create enough back pressure to raise the water level in the tee to the desired point. So, wouldn't that also be the case of the output going up 24" before exiting? What I don't know is whether forcing the output up 24" is MORE back pressure than this setup can handle. Or, if I add a few inches of 4" pipe to the foam output, and let the water level come up a little further, would that reduce the amount of foam that exits the tee?
What is your opinion about all of this, please.
Thanks!
Regards,
Todd
