DYI Standpipe

[sphelps]

I'd stick with using a bulkhead.

making a stockman pipe right now...let you know how it turns out..

Just hate that I had to buy a full 10ft stick of 1.5" PVC just to use 20" or less

1.5" is pretty big, what size coupling are you using?

[Magma]

2"

[sphelps]

That will give you less than a 1/4" clearance so it'll be tight but I guess you're not pushing much flow anyway. You might not be able to get it super quiet with the over sized pipe but let us know how it turns out.

looking around a lot of people say that if you have 1.5" pipe and use a 2" coupling it works great so, figure why not try

If you look up 'hofer gurglebuster' you'll come across another method of quieting your drain. I believe it's actually a variation of the Stockman. I don't have personal experience with either of these and did read that it may be more prone to clogging, but you may want to investigate nevertheless. Here's a link to get you started.
