OK, I changed the overflow and line to straight 1.5" pipe all the way down to the sump and if anything it is noisier now! It is a swirling rushing water sound. Not flushing and not even really gurgling. The sound of water rushing down pipes. Like if somebody upstairs flushes a toilet and you hear the water rushing down the pipe.
The T at the bulkhead and pipe are angled down at roughly 45 degrees and I used only 45 degree elbows to get it down into the sump so there are no hard turns for the water to make.
I've also tried increasing or decreasing the flow from the return pump. Doesn't seem to help.
This thing is driving me nuts as I can't get it quiet. Help please!!!!
