Whomever comes up with the "Durso-pro" version that is quieter is going to be rich! Here are my thoughts.

First, as a DIYer I bet you are used to building solutions that actually solve problems. It is my experience that the Durso Standpipe, while providing a SIGNIFICANT reduction in noise in your overflow box, does not eliminate the noise.

The one modification I would offer is - rather than toying with a dozen drill bits in search of the perfect size air hole in the top of your cap, drill a 3/8" (or so) hole THROUGH THE SIDE of both the cap and the top of the standpipe. Then you can adjust the airflow by twisting the cap, increasing or reducing the size of the functional air hole. Very convenient for adjusting and has worked great for me.

However - the noise continues... A LOT LESS noise than prior to installation of the DS, but persistent noise all the same.

We have tried a ot of things to quiet that box in our living room and have surrendered to the 'peaceful' humming gurgle of a healthy tank. As Teri once remarked, the sound of the tank is the reassuring hum you hear when entering your house - confirming that all is good

Also - I think the higher your Standpipe, the shorter the distance the overflow water will fall into the overflow box. That saves on some of the noise at this point in the process. THe water level in our overflow box is only about 1.5" lower than the tank.

One other thing that has helped to quiet the gurgling sound has been to close off the hood across the back, thus 'trapping' the noise under the hood. We have a fan and a vent hole (on the opposite side of the tank from the overflow) to keep the lights from cooking the tank.
