What I ended up doing was putting a ball valve on the drain line and choking it back to keep the water level higher in the overflow. This stopped the sound of the Niagra falls in the overflow and kept all the holes deeper under water so now my drain tube is under water so now it's more quieter almost respectable.
I really didn't want to put in a ball valve cause if a snail gets into the plumbing that where it will get stuck causing an overflow, anyone know where to get an 1.5" strainer?
thanks for the help guys
