I bought an Auto Siphon several brews ago, and have never had good luck in getting the thing to work properly. I bought the Siphon brand new, and the 3/8 hose that the packaging indicated. Every time I try to start the siphon it goes for a minute then just stops. I've tried putting a zip tie around the hose/cain connection, and this helped a bit but it still was stopping every few minutes. Then while in the middle of racking the other night, the little poppet that keeps the wort from flowing back out of the siphon just poped out when I opened it up to see what was wrong. I ended up having to ladel out the rest of the 10 gallon batch with a pint measuring cup. Not fun!

Anyone have any suggestions? I already tossed the broken one in the garbage. Has anyone had good luck with a certain brand? I really want to be as clean as possible and don't want to have to ladel or start a siphon with my mouth.

I have this one http://morebeer.com/view_product/6355/ , it works great. Unfortunately it's temporarily out of stock at Morebeer but I'll bet one of the other big online shops have them

I think that for the 3/8'' Autosiphon you really should use 5/16'' hose. I switched to that and had no more problems.

I've had one since my first batch. The only time I had problems was when I tried to buy some new tubing and it wasn't the right size. Probably the same problem as the 3/8 5/16" mentioned by Beerrific.

Beerrific is right. the instructions say 3/8" but my LHBS said that was just flat out wrong. I actually split some 3/8" trying to get it on there. the 5/16" works fine though, and is still tight enough that it doesn't leak at the top.

there is still a trick to most of them though. often air will get trapped right where the hose connects to the cane. if you just pinch it a little when that happens, you'll burp the bubble through.

we usually get all paranoid about that air bubble causing oxidation. even if it doesn't, you get a better siphon by pinching it off.

they make a mini-siphon too for 1gallon jugs, and its cane looks smaller...I think it would take 3/8" tubing. Maybe.

Interesting, mine definitely said 5/16'' I know becuase I was I told SWMBO "Ah, 3/8'' will work." After sucking a bunch of air into my beer and getting pissed, she rolled her eyes at me and I got some 5/16''. Is yours Fermtech? Maybe they updated the instructions.

It's a 3/8" OD cane, but you really need the smaller 5/16 ID tubing to get an airtight fit. I know it's been said, but sometimes you need to hear it a few times before you stop beating your head against the wall.

It might not fit at first but if you put the tubbing in boiling water it will soften enough...I have yet to get mine off

I use an autosiphon with 3/8 and don't have any problems at all. Just a pump or two, stick the hose under the wort / beer level and let it fly!

Jekster,
I'd look real close at that joint while you're running the siphon. You may find that air is getting sucked in. It's not enough to stop the siphon all the time, but you're risking oxidation. There's a chance based on allowable tolerances that your cane is a little larger and your tubing is a little smaller, but most of us have had major problems with that combination.
