Modding your Sodastream

Modding your Sodastream

Sodastream or SodaClub creates a product used to make your own soda at home. This device blasts CO2 into your water, converting it into seltzer water. You can then add your favorite syrup to turn the water into a yummy soda. I love my Sodastream until I found out how much it costs to replace the CO2 tank. A tank exchange will cost you almost $20. Moreover, you can’t fill the tank at a paintball store because Sodastream has their own unique valve on the tank. If you are like me and drink soda everyday, you will go through one tank/month. $20/month for CO2? HELL NO!

I had to find a way to relieve my ass from the anal pounding I was receiving from Sodastream. This was my solution. Yours may vary depending on the setup you would like to have. I just wanted to find a way to fill up my tank from a larger CO2 tank at home.

Warning! – Do any of this stuff at your own risk. I am not responsible for your stupidity.

1. Buy a 20lb tank from craig’s list. Cost- I paid $70. I may have been ripped off, but I’m not a gas man so I wouldn’t know. I saw prices on Amazon for about $100, so $70 felt about right to me. Be sure to get an aluminum tank. This tank will be exchanged at a company called “Airgas” for about $18. This should last more than a year, but I don’t know yet as I’m still on my first tank.

2. Buy the professional fill station with an adapter at SodaCo2. Cost: $125. These guys did an amazing job making their adapter for the Sodastream valve.

3. You’ll have to modify the valve as shown in this video:

Here’s information not on the video. The “easy out” is actually called a “Screw Extractor”. This was a product I had to buy because I did not have it on hand. I purchased the Black & Decker 16270 set because it was the only one at Home Depot. I found out later that the reviews on this product are god-awful. Fortunately it didn’t break on me, however, the extractors are not labeled with sizes; just labeled from 1 – 5 (very useful, you assholes!). I made a quick chart here with the sizes:

Black & Decker
Screw Extractor 16270

#1 – 5/64″
#2 – 7/64″
#3 – 5/32″
#4 – 1/4″
#5 – 9/32″

I used the #4 – 1/4″ for extracting the part described in the video. Unlike the guy in the video – it took me a few tries to get the screw extractor in to eject the piece.

4. Fill your tank as shown in this video:

This did not work for me initially. When I went to fill the tank, CO2 leaked from the sides. I ended up using one of the rubber o-rings that came with the professional fill station. I put the ring on the sodastream tank like so:
sodastream valve,

I cannot get a complete fill. I’ve tried cooling the tank as shown in the video, but still no luck. After filling the tank for a while, it will reach a point where you can feel that no more CO2 is going into your tank. This isn’t bad, the tank just doesn’t last as long and I have to fill it up a little more often. Right now, I’m refilling every week or so.

In reading this article you probably figured out that I’m not an engineer. I’m just a humble graphics guy, and have no clue about gas. I’m showing what I did to inform other folks as retarded as I am on this subject. If you have other tips and tricks, please share with me. I love learning new things and that is why I loved doing this project; it was completely outside my talent base. Finally let’s do the math on this project. I spent about $200 for a working refill system. It will take slightly more than 10 months to get my return on investment.
