In the top back of the DT there is 4 bulkheads. The two end ones are return, the two middle ones go right to the fuges. If I put two 90* on the middle ones facing up to raise the water level in the DT will I find any noise issues? This will be in my bedroom. So the water would be pumped into the DT, flow down into the bulkhead, into the fuge, then down the standpipe.
-In the fuge, should I have the water level at the dark or light blue line?
-Will this be silent?
