Higher- I'll do my best to answer:
So I have 2 returns and one over flow. All are on a ball valve. And I did play with them. Today I tried do 45s instead of the 90s on the overflow.
The guy that had the tank before me did come over and we played with the plumbing a little bit he had some great ideas. One involving the 45s.
I basically out of ideas but will play with it more tomorrow and the rest of the week.
I think Jeff doesn't need a plumbing party. I think I need the help. (Lol)
