Eliminating 2" 90° elbow

Postby newfie » Fri Jul 07, 2017 4:26 pm

I'm planning on doing a still similar to the one attached. I noticed that most of the designs all use a 90° elbow before it reduces it to a smaller size. Is this really necessary? Couldn't I just reduce it down and then use a smaller 90° elbow? The reason I ask is because I'm in Canada and those 2" elbows are not cheap to buy online and have shipped. I'm still attempting to locate a local plumbing wholesaler in the area that has 2" copper rather than ordering online.

Plumbing supply houses (not talking about big box stores) should have then at a reasonable price (if your talking about a copper 90 like you have in the photo.

yeah, I'm going to be checking them out in the area. I meant to call them today but it slipped my mind. lol

My question is if I don't find any locally, do I need to have that 2" elbow? Couldn't I reduce it and then use a smaller elbow?

you can, but i reduced 2" to 3/4 on a short line arm dumping into a 2" shotgun type PC. No evidence but something tells me i'd be happier if i went 2 the whole way...the reduction speeds the vapour thru the lyne arm and then slows as it enters the larger PC, if my cooling water is too cold it huffs, and it is not a very efficient PC with warmer water. but thats all guessing since i never changed it yet.

but technically yes, you can drop to 3/4 without any catastrophic problems. hell, mine makes damn fine likker.
I finally quit drinking for good.

now i drink for evil.

Here's something to consider- use a tee instead and be able to use it as a ccvm later. You may not be thinking about that yet, but it is a very versatile piece of kit.

Cool, that might be a good option. Thanks

IF you're going to reduce it anyway - why does it matter where ? Use a reducer straight after your tri-clamp and save teh cost of the elbow And the 2" pipe.

IMO you could take it straight down to 1" and run a column say 48" giving you some passive reflux, Then use a long Leibig saving the cost of 2 more reducers and another length of 2" pipe. Depends on your heating wattage of course, but if you're considering 3/4" that can't be very high :)

[Edit - Your column as shown is nowhere near long enough to make a VM adaptor later. ]
[Edit 2 -- Your photy shows a leibig, sorry I thought you said a 2" shotgun - My Bad - forget "2 more reducers and a length of 2" pipe" :) ]

Sillstirrin, just posted somewhere about that exact same question. I can't remember where but he had a great explanation on that subject.

I personally like the way that still in the pic is set up :thumbup:
15$ for an elbow isn't too awfully bad, I'm on a budget to a degree (wife) but I'd also throw in some unions to make it to where that if you didn't have a level surface you could raise or lower your rig to just about any height needed without the Hassle of trying to level the ground.

yep it will work.
my pot is 1.1/4 and reduces to 3/4 before the 90, works good.

As ShineRunner mentioned a T is a great option if you have interest in the odd vodka run as well
