New Drain Design

[mark]

could work, like you said playing around and trimming fittings to get things to fit and adjust for height. Wouldn't worry about rattling as could easily brace with spacers. Tightest part probably the getting the inner elbow to fit.

Here's some idea of pipe size, 1", 1.5", and 2" thin walled conduit.

Thanks... yeah I think it would work especially considering most of my drains were only 1/2" or 3/4"... so far.

I forgot the tank would still need another bulkhead for the return line unless it just came over the back??

Cool idea! - please update on the progress

I think that will work and it is a very inventive idea. You're in for some tricky plumbing up there in that elbow section. You might have to cut an elbow in half, then weld it back together in order to get the small elbow inside it.

Interesting idea, although I am having a bit of trouble conceptualizing how you would prevent most of the water from going down the larger emergency drain during normal operation.

If you somehow designed some kind of a weir that directed the water only into the smaller interior drain, there may be some difficulty with tuning since you'd have trouble see how close the interior drain was to being "full". In a standard Herbie this is easy because you can observe the water level in the overflow space. It would be difficult to do the same in your design. You can't even observe which pipe (inside or outside) the water is exiting from in the sump since a truly silent herbie requires the drain pipes to be submerged in the sump.

I used a design like that about 5 years ago as one of my first ones.. didn't like it as it was hard to quiet down even with external durso's and it plugged up with algae causeing me to have to clean it almost every day.

you could use soft tubing for the inner tube, solving the problem of fitting in the 90.
