I was getting ready to try the Durso standpipe when I was wondering if this would actually solve my problem. My question is this to all of you out there that use it. Does it make noise at the sump? Right now I have an AGA over flow and it works "ok" but every few minutes a big air bubble goes down and it releases in the sump to make a bubbling noise. So what I was wondering does the Durso make the same noise? Since it to sucks in air? Thanks So very much..
