Durso Standpipes Silence Your Overflows!

I used your Durso Standpipe overflow design instead of ordering the AGA overflow kits. I filled the thing with water today and test ran the system. It is amazing how quiet they are. Really just amazing. I have never had a tank this quiet. I am running a MAK 4, about 1200 GPH at 4′ of head. Since the AGA corner overflows are somewhat smaller than Oceanic, I found that I had to cut down one branch of the 1¼” tee and the elbow to get them to fit, but then it was no problem. Thanks very much for your innovative design, this is a genius of an idea.
