you do lose the "height equivalent" of the distance between the two horizontal tubes.
- you might
be able to get away with a single (larger) hole, containing 2 pipes inside it. One is a drain from the Boka plate (liquid out to valve) and the other is a valve-out, returning liquid to the column centreline......? The pipe diameter must be able to cope with the maximim flowrate of falling liquid (not that much, even on a high-output still!)
Small is beuatiful, especially when it doesn't have
to be big.
And it's cheaper.
Thanks - I like it, you said - "Small is beuatiful, especially when it doesn't have to be big. And it's cheaper"
Small is not
cheaper, 8mm fittings are ridicoulously expensive - 15mm fittings are cheap.
So, if we increase the loop to 15mm the only part that needs to be small is the vertical leg subject to pooling we can still make that 8mm or even 6mm.
By inspection I believe that the 15mm pipe and bends will be able to cope with the maximim flowrate of falling liquid whatever that may be - I have never seem a still pumping out 1/2" full bore.
Which leaves the loss of 1.1/2" of "height equivalent" being the distance between the two horizontal tubes. I am not too sure where this fits in. Is it the height equivalent of the column? - if so do I just make the Boka 1.1/2" taller? or what effect will the loss of 1.1/2" of "height equivalent" make.
The sketch is showing a standard valve, I will make one of my valves with 15mm fittings in a couple of days when I get back from my trip.

You could S bend it back to come back under tab and lower then valve. If you also put small up bend in it you would have slight pooling in it and close off the funky vapor looping minime might be thinking about.
Edit= 1/4" soft so it would drain off and not hold too much volume where you do create the pooling at end inside column.
Azframer Sorry - Rick,
Sorry mate I am having a bit of difficulty trying to imagine what you are suggesting. Any chance of a picture of some form - easiest way is to draw it with a pencil, and photograph it with your web cam and send like this
It only takes a minute and saves any confusion
