Finally got the pipes plumbed out.
I've added fresh water to test out everything and flush the whole system.
So far, I've noticed that my pump(Mag 9) is pumping the water faster than my drain pipe can handle if open at full. Maybe I should've gone with a weaker pump. So I need to throttle it down.
Also I need to raise the height of the drain pipe in the overflow so the sump doesn't get overflown with water when the pump is out. This will also allow the overflow chamber to hold more water so that the water splash won't be so loud.
