If it isn't broke, don't fix it...especially when you don't do any product testing...
I was reluctant to buy this product because of the negative reviews I have read on NB. The only reason I did buy it was because NB stopped supplying the auto siphon that they have been selling for years to move forward with this brand because "the plastic is stronger and you can take it apart to clean it" yada-yada-ya. If you take care of your equipment and clean the old auto siphon like you should that would wouldn't be an issue. I did see some cracking in my old auto siphon but it never led to any infections or problems of any kind. If the cracking became a concern or stirred paranoia of infection, the price point was fair enough to simply purchase a new (old version) auto siphon. Done deal!That was my plan this go around but, since NB stopped supplying their old auto siphon for this version. I was given the golden opportunity to try this new product out, which in theory sounds great, really...I like the idea of being able to disassemble to clean but from reading reviews I could see that any lack of seal could lead to issues during the siphon. I did voice my concerns and referenced the reviews to the NB associate in in the store and she was very accommodating and let me know that if there were any issues with the product to bring it in and they will figure out something. I do intend to return this.Well, one oxidized batch later, I am done with this product. In hindsight I should have stopped the siphon and figured out another solution when bubbles of oxygen were flooding my siphon tube from the lack of seal. Call it stubbornness or maybe I had faith that the "rack magic" would magically...eventually work, but it didn't. I just want to be clear that I have no intention to slander NB, I have been shopping here for years and the customer service is top notch. I just would recommend that no one buy this product and NB at least give the consumer an option to go back to what is familiar and has been working for years.

Hi Ryan,

Sorry to hear about this! I agree that you should definitely visit the store about it, but let me know if there is anything that I can do for you as well.

Excellent idea... execution?
Love being able to disassemble for cleaning. But does it actually do what it's supposed to? Nope. One to two pumps to start flow? Not even close. Had to pump furiously to get flow to begin. Checked the end caps, made sure they were tight, made sure cane was more than two thirds immersed. Still no improvement. All the pumping kicked up the sediment at the bottom of the 2ndry on bottling day. Good thing "pirate's plunder" is a dark beer. People won't see all the sediment floating around. Judging by the other good reviews I may have just gotten a defective one. My advice: try it out BEFORE bottling day, otherwise you may end up like me.

Response from Northern Brewer
Luke- We are sorry to hear that your Rack Magic wasn't working properly. We want the one you have to work great. The need for extra pumping could have been caused by the end cap being too tight. Loosening the bottom cap 1 to 2 revolutions will widen the gap between the two outer bands will increase the flow rate, which should make the siphon start easier. If the Pirate's plunder doesn't meet your standards, we would be happy to replace it with our Kit Guarantee. We want every beer you make to be awesome. Cheers, Todd J

Rack Magic Blows Bubbles
I had a hard time getting the Rack Magic to siphon and when it finally did, it blew major bubbles into my finished beer, likely causing serious oxidation. I was very unhappy. I called NB and spoke to Craig and he took care of me, replacing the Rack magic and my brew recipe! Thanks Craig and NB! Great customer service. Despite my trouble with the Rack Magic you have made me a happy and loyal customer.

Doesn't work
First time I am disappointed with something bought from NB. I have my old siphon but after seeing this one I bought it because it is supposed to be faster, better etc. what it did is take a lot of air while racking, pumping the beer from primary to secondary and mixing a lot of air with it. Not good. I cannot find the invoice to return it??
March 23, 2016
Response from Northern Brewer
Customer service will contact you. We are dedicated to helping every brewer with any and all issues. The bottom anti-sediment cap is adjustable and if it is too wide or too narrow, may result in issues with siphoning, whether clogging or letting air in. Or yours may have some defect and a replacement could be in order. It is also important to use tight fitting tubing to avoid air entering at the top connection. We'll find a solution to every problem. Cheers! James J

Cracking From No Damage And Too Much Air
First use was, for the most part, great. There was a bit more air in the lines than I would have liked but, not enough to keep from using the siphon. The next two uses had more bubbles than beer flowing through the thing so, I always ended up using my older equipment. This happened again on the final (4th) use but, while cleaning everything, I noticed tiny cracks everywhere. Little patches of spider web cracks all over. This thing was barely ever used and I know it never sustained damage. I'm guessing this was causing the air problems all along but, I'm unsure. Wish I'd have listened to more of the negative reviews before buying.

Response from Northern Brewer
If air bubbles are appearing during the transfer, you may have a slightly missized gasket - try decreasing the distance the beer flows so the tubing does not pull the inner cane out of place. Customer service can resolve these issues and make sure everyone gets a stellar product so please let us replace one experiencing this problem! Cheers!

No good.
Similar to many of the reviews below. Can't get a good vacuum in the siphon - it takes multiple pumps to get it going which stirs up my yeast cake and oxygenates my beer. Had it for about 4 batches and thought it was just me. Looked online for tips and videos, tested it in water and still can't get it to work properly. Hoping to find a NB instructable video but don't see one - I can guess why. Very frustrating. I must say that NB has been good to me though - this is their first miss.

They should call it the mini bubbler
Glad I'm not the only one having an issue. I like the "blows bubbles" review. This thing was kind enough to oxygenate my entire batch on it's way into the secondary. I guess now I get to see what the off taste of "oxidation" tastes like. It's a shame it had to happen on the $60 Storm the Bastille kit that I'd successfully fermented with yeast harvested from a Dupont Saison bottle. Came in around 9.5-9.75% abv and was tasting very nice. Maybe I'll get lucky and the batch won't be completely ruined, but I'm dumping this thing and going back to the original siphon if they still sell them.

Absoultely horrid
Had an auto-siphon for nearly 12 years. Worked like a charm. It finally broke. Bought one of these. Found the multiple piece screw on header to be unnecessarily complicated. Also could never get the thing to form a good seal, requiring multiple pumps to get it going. The deal breaker through was when, about 4 or 5 batches in, the cane seal folded over when inserting it into the tube. After that, I could never get the cane in the tube without the seal folding making moving the cane up or down impossible. Purchased a new auto-siphon. Couldn't be happer. Don't waste your time or money. Buy an auto-siphon - and no, I don't know anyone that works there who makes them and no I don't get any money or compensation for positive or negative reviews of anything. Just my experience and opinion.

Rack Magic Issues
I've had the Rack Magic for several batches but as of yesterdays transfer, I'm throwing in the towel. Frustrated beyond belief. Initially the cane seemed to work well until I noticed all of the air bubbles it pulled into the transfer hose. In fact, the air is to prevalent, it typically stops siphoning at 2/3 of the better bottle. Taking it apart and cleaning is fine but regardless of how much or how little I leave the bottom take-up open, the air bubbles continue and the siphon is lost. I've had it way too long to seek a refund or replacement but I'm here to tell you that this product is not worth the frustration it creates.

First, I love NB. I buy tons of their kits and gear and have nothing but respect. But this product should be much better than it is. The first rack magic I got barely worked. Its too bad, it looks like it's well made. It is highly prone to clogging by trub on cook day or by hop residue from dry hopping. I used it once, cleaned it, and went to use it again a month or two later and the inner part was covered in tiny cracks. After sanitizing it and assembling it, the inner part literally exploded into pieces and this was a complete disaster as I was bottling a barely wine that had been aging for 8 months. I was able to salvage using tubing alone (stuffing tubing into carboy, thumbing over, and then pulling most of it out to get siphon action).

I contacted NB and got a replacement which I appreciate. However that cane is just like other reviews, it sucks in huge amounts of air somehow from the inner assembly. I tried adjusting the end cap multiple times (testing with water) and nothing would work. Hopefully this didn't affect the Pliny progeny that I was bottling. I don't even want a replacement. I need to find the old model like I used to have.

I am curious if there is a trick to using this so it doesn't introduce massive amounts of air bubbles while siphoning? I had to stop/start the siphon about a dozen times the very first time I used it due to an insane amount of air coming through the line. I still bottled the beer (my first batch - let's just say my hopes are NOT high), but I was so disappointed by how much air came through. I know the bottom is adjustable, so I'm curious if I should tighten it down more to slow the siphon down? Any help would be greatly appreciated.
David P on May 3, 2016
BEST ANSWER: It sounds to me like yours is not working right! It should not leak air into the siphon hose as it moves liquid, that would indicate that there is an air-leak in the seal on the inner tube of the siphon, or air is leaking at the hose connection to the siphon. If 5/16" tubing is used, it should not leak at the hose connection, as it is very tight, so it may be that it's leaking at the flexible seal on the internal tube. If that's the case, we can replace this unit for you. Take a look at yours and let us know if that seems to be the case, we would gladly send you a new one! -Mike W, Northern Brewer
What is the temperature limit on this siphon? Can it be used to transfer liquids that are heated to 180 F degrees?
C A on Jun 7, 2016
BEST ANSWER: I wouldn't try. I had the older version of the siphon and used it for warmer wort temps. The bottom of it warped and it had to be replaced.
I have been having trouble getting my Rack Magic siphon to start after two pumps in some of my beers. What is going wrong?
C O on Apr 7, 2016
BEST ANSWER: There are a few things you can do to ensure that your siphon will start more quickly:

1. Make sure that you have wet the seal in your siphon, while you sanitize. That will make it easier to pump the siphon and go through a full sweep of the pump.
2. If you have disassembled the bottom tip of your Rack Magic for cleaning, make sure that the gap at the bottom tip is at least 1/8" after you have reassembled.
3. Do not stick the tip of the Rack Magic directly into the trub that has settled at the bottom of your beer. If there is too much trub to rest the tip on the punt at the bottom of your fermenter, hold the Rack Magic tightly against the side of your fermenter with one hand while you pump with the other. This will help prevent the trub from getting sucked into the Rack Magic and clogging the siphon. It will also keep the Rack Magic from stirring up all of the trub that you have let settle out.

That should help get the siphon flowing. If not, please contact us to help further.
Hope it helps,
Todd J
The first time I used this, I had very little suction. At some point, I gave up and dumped the rest of the wort out. I may have reassembled something incorrectly after sanitizing. Do you have any ideas?
S A on Feb 27, 2016

Sorry to hear about that. Were you able to get any beer into it all? Perhaps the bottom cap was screwed to tight. I would also check the gasket on the end of the inner tube for damage. I'd also try it out with water to see if you can get it to work. If you can't, let me know and I'll have a replacement shipped out for you.


what is the outer diameter of this? will it fit in the mouth of a 1 gallon glass jug?
P L on Feb 16, 2016
BEST ANSWER: The widest part is the plastic fitting on the bottom. This is 1.017 inches in diameter (measured with my calipers). I wonder, however, why you need a siphon to empty a 1-gallion jug. Couldn't you merely decant by pouring? The housing of this device is 23.5 inches long. Seems like it would be cumbersome, using it with such a small jug.
What size clamp do I need for this? I'm guessing the 1/2 inch, but I want to be sure before I order.

L U on Feb 15, 2016
BEST ANSWER: You'll want to use the 5/16" AutoSiphon clamp, part #7151. This will fit onto the new Rack Magic Siphons. Have a good day! -Mike W, Northern Brewer
Is this the product that comes with the new small batch kits? I had issues with it and reviews seem to imply I am not the only one...
A shopper on Aug 29, 2017
BEST ANSWER: Yes I bought the same one and it has never worked yet. It never seems to prime
Can I buy a new seal? Mine leaks air.
A shopper on Jul 9, 2017
BEST ANSWER: We do not sell parts for the siphon. Sorry for any inconvenience. Cheers!
What size hose should I use on this? Would this product work? http://www.northernbrewer.com/5-16-id-siphon-hose
S C on Feb 19, 2016
BEST ANSWER: It works best with 5/16" ID siphon hose, but 3/8" will work as well.
Can it be sanitized with Alcohol 70%?
