I'm of the understanding that in order to do a Herbie overflow you need two holes drilled. The overflow box doesn't have the space and the tank is already running so that ship has sailed.

You can do a herbie with a single large hole (2") but if you're having issues finding parts for a 2" standpipe then building a single drain herbie will be a much greater challenge. Here's a drawing for reference, if it's really something you want I could probably build it for you and ship it to you.

I think that is brilliant! I certainly understand how that might work assuming you get adequate flow through the gap between the 1.25" and 2" pipes.

Has anyone built/tried this with any success & if so would anyone with the skill/know how care to help me to build one, or even build it for me ? Will pay accordingly.

My durso is completely silent. I do have two 90 deg bends in the lines before it hits my sump however.
