Hey guys tuning my 500 gallon system and am having trouble quieting my 2 overflows. I am using the H2overflow which is drilled into the back of the tank and elbowed down behind the tank and under the stand into the sump. I have 2 of these installed so two separate 1.5" drains running down to the sump. Here is a loud rushing water sound through the pipes that is irritating even from the front side of the tank. Is there a way to reduce this slushing/leaky toilet sound that is constant? Thanks
