- How to fill a sodastream cylinder for cheap. works with any Co2 tank, airbrush tank, paintball co2 tank soda tank or kegarator co2 tanks. Cost $1.
If you have concerns about the chance of over filling your tank I suggest buying a digital scale, you can then zero out the weight of the empty co2 bottle then simply put in 410 grams of dry ice. Also you do not need to put the valve on that tight. They over torque them at the factory to dissuade ppl from filling tanks them selves. Place valve on finger tight, then use wrench to hand torque it the rest of the way. If your not confident on the amount of torque then tap firmly on the table once or twice. If you have any doubt's, I own a dive shop and have been refilling tanks for 20 years. Using these instructions you can safely refill your co2 bottle for many years. O rings can be found at local hard ware stores I suggest finding the right replacement and have some on hand just in case.
+Michael Cowan Thank you.
Conversion: 410 grams = 14.4623 ounces
Michael Cowan thanks. plan on following your advice. first question I had from this video is how MUCH dry ice. didn't want an unintended failure...... thanks.
Morning wood with MonsterHogg41 to expand on torquing, typically when a properly torqued bolt or thread has been on for an extended period of time it will seem more difficult to remove than it was to put on, if this makes sense.
When is it usable after doing this?
Just a thought on o-rings, they are not all designed to go down to the -110°F that dry ice may subject them to. Go with a silicone or fluorosilicone o-ring. An o-ring that is not designed for this temperature will become brittle and have a higher chance of failing especially when torquing the cap on. The Space Shuttle Challenger accident was the result of cold o-rings.
You are a genius! I have the 33oz bottle and there was no way I was going to send it in and spend $30 or whatever it is, every time. I tried this today, and it worked like a charm. I bought 2 1/2 lbs of DI and this sucker is charging soda like it's brand new. Thank you my friend, like I said, you are a genius. Because it's the little things that make life easier, that mean the most. I bought my ice at Lucky's.
Bottle got super cold and covered with frost for about two hours...but at the ~ 3 hour point, it was room temp. I screwed it back into my SodaStream and had perfect bubbles. Total cost of 2# dry ice: $2.50. You could get by with less than 2# of dry ice but I didn't know how much I'd lose in the process...2# was pretty much what I needed when all was said and done. Thanks again for the great vid, stetkal!
Brilliant. This video with all of the combined wisdom from the commentators is awesome like the guy who has been running a dive shop filling up tanks for 20 years. We can all take on an environmental habit while saving tons of money, and not being a victim of the inappropriately costly refill. I encourage anybody who is thinking of adopting this method to read through a lot of the comments. Thanks to all of the positive commentators!
Super easy, takes 10 minutes. I use the 130L bottles, which holds 34 oz. of gas, I used 1.7 lbs. of dry ice for $2.53. Huge savings and it tastes like normal. I tweaked your system slightly by using an old 10# ice bag (a freezer bag would work too) to smash the ice in. Still used a towel over the bag. Kept everything contained and it poured from the bag right into the funnel. No scooping needed. Took about 4 hours for the frost to disappear. Thank you!
I've been doing the dry ice refill thing for several cycles of three of the 60L bottles. I weighed a brand new sodastream cartridge on a digital postal scale and it weighed 2 lb. 6.5 oz. full. To refill 3 bottles, I buy a 5 pound brick of dry ice, put it between the folds of a large towel on my garage floor, pound it with a 3 pound sledge, pick up the dry ice dust & small particles with a large metal spoon and dump it into a funnel going into the open bottle. Then I use a metal skewer to push the pieces into the bottle through the funnel. I weigh it several times as I'm doing it, with the metal valve cap also sitting on the scale. When I get to the full weight, I close it up and set it aside and let the dry ice pressurize the bottle. Gloves are handy but not necessary as you never need to touch the ice, but the bottle gets cold. Don't go past the full weight and you'll never blow the safety disk. If you get it too heavy, bleed off the excess with the safety screw down to the full weight or it will either blow the safety disk or jam the valve. You need to be fast...every second the dry ice sits there, it's evaporating. Spending $8 and 20 minutes to refill 3 bottles beats $45 plus tax at the store any day.
Fact!
listen to this guy if you add too much dryice you can over load the tank. when dry ice "melts" it can reach 1000PSI if the tank is faulty from too many refills and not being checked by the factory for integrity you can easily kill someone!!!!! or a whole room of your not careful.
Dan JW I overfilled my tank one time, it just blew out the safety valve. I also always leave the tank somewhere unattended for awhile after filling and putting the top back on. It always gets very cold and a lot of frost forms on the outside of the tank. After a few hours it's easier to handle and I assume that if anything were to go wrong it would have.
+Dan JW they have safety valves that trigger whenever it exceeds the max pressure for the canister
Throughout the entire video, I was distracted by the overwhelming bad-ass-ness of Flea.
This totally worked, to the utter amazement of my wife and kids! It took quite a few good thwacks to get that top off but it finally loosened and I just unscrewed it...no other parts to worry about (based on other comments, I had a concern that there might be odd pieces of metal or different washers, etc). I did not repeat that process to tighten, just used my wrench and all the strength I could muster so it'll be easier next time. I have the skinny bottle that holds the 14.5g of CO2.
Thank you Stetkal..What a nice thing to say. I sure do appreciate your well wishes...You're very kind to share your wisdom with everyone.
NICE! Worked great! Thanks for showing me the way. I'd thought of trying this a while ago but couldn't get the top off. Chunk of wood and a adjustable wrench worked a charm!
To make crushing and loading the dry ice into the cylinder easier, I smashed it into 1" to 2" rocks and put them in a food processor till it turns to snow. Spoon it into the funnel and the "snow" goes into the bottle like sand.
That "snow" is also great for making "instant" ice cream. Mix up your favorite recipe for ice cream, put it in a big bowl, then add some of the snow (not too much or it'll bubble over). Mix that up on medium speed, then add the rest of the "snow". It's ready to eat on the spot but will have a little fizz. But its even better if you pack it in a container and let it temper in the freezer for an hour or two.
I have done this method 2 times now and it works good. I have better tools (like a bench vice) to work with but the method itself works. I actually start out with about 1 ounce more dry ice than necessary which gives the tank a little more pressure so the first couple bottles of soda have more of a champagne bubbly than a soda bubbly. If you have two tanks you can use this method and never have to worry about being stuck with an empty tank.
This totally worked! it costed me about $5 for my dry ice at a party store for convience of going to a closer store and not an ice place a few more miles away. and with the left over ice I put it in my fountain, very cool. I used a aluminum baking pan and snowbording gloves and it really helped a bunch.
Thanks! This worked great. I did this myself last night and tested the canister this morning. Worked wonderfully.
1. I took the safety valve completely off (dumb move) and almost lost the tiny little piece that looks like a sequin that was beneath it.
2. I had to hit the wrench quite a few more times than you did in the video (MIGHT just have something to do with being a 5' tall woman).
After three years of trading canisters for $15 each, this was a WELCOME solution!
THANKS!!
When I found out that it was cheaper to fill my ten pound kegerator tank and that I was lied to by this company, I tried to find something about this with no luck. Just figured dry ice is solid co2, I'm putting it in a co2 tank should work right? The first time was scary as hell! I have done this about 18 times now with no trouble. Never thought that this many people would watch this and I hope that they all try it instead of dealing with these crooks. Thanks for watching and all the comments.
Love the impact wrench. That's truly "old school".
I've had my soda stream for about 6 months and just ran out of the carbonator. Took me about five minutes to add the dry ice one pound exactly and it worked great.
Now that is really inventive, good job adding the collective knowledge of the world and saving money to the people who view your video and apply the knowledge.
I did this two days ago and it worked perfect. I used a food scale to weigh out the dry ice so as not to overfill the bottle. My bottle was marked 14.5 oz. so I weighed out 10 oz. to be on the safe side. Once the frost was gone from the outside of the bottle I installed it. Works just like a brand new CO2 bottle but only used about $1 worth of dry ice.
Thanks for the detailed video showing all the steps. I had to watch the removal of the valve a couple times to see how you did it - mine wasn't budging using my technique. Once I saw how you held the crescent wrench and the tank, it was easy to pop it loose.
I must have moved too slowly with the dry ice, though - 2.9 lbs of ice barely filled my cylinder halfway.
brilliant! i just bought a sodastream today after a demo by one of the store employees... luvin all the vids i'm seeing on this so far...
Man I want to thank you so much. I found this video when my first tank ran out. Since then I've refilled it myself many times! $17 for an exchange.. pffft! the hell with that!
This is awesome and it works! The best way to open the cylinder the first time is to clamp down the cylinder on a table vice and then use a 15/16th wrench and hammer to loosen the valve. Some valves take longer to open than others. I have 2 cylinders so it is more cost effective when you are forced to buy 10 pounds of dry ice. I'm thinking of getting a 3rd cylinder to make it even more cost effective. There's no place to buy dry ice here in Vancouver so I buy it at Fred Meyers whenever I go visit relatives in Seattle.
The O-ring will seal without pounding the valve tight, once it bottoms out the seal is made. It only needs to be tight enough that it'll stay tight when you remove the bottle from the machine, basically just tighten with the wrench and no need to pound it. This will make it easier to remove the next time. The O-ring should be lubricated with a food grade lube to keep in in good shape for many fills, reinstalling it dry will wear it away and can actually tear it creating an immediate leak.

Somebody had to say it; that was painful to watch!
you, my friend are a genius! I love my soda stream, but I just have a hard time justifying spending $15+ each refill, I like my soda extra fizzy, so the tanks only last about a 7 - 10 days.
This is amazing, just bought my first sodastream and I'll be trying this for my first refill.
I solved the leaking problem by adding a number 15 o-ring, now doesn't leak anymore. Also my neighborhood Airgas sells CO2 pellets that fits right in! Thank you very much for the tip!
I just got around to trying this, and here's by observations:
1. I was able to loosen the valve body by placing the bottle in a vise (protected with rags) and using a 10" adjustable crescent wrench.
2. Get the "pellet" style dry ice (from places like Praxair), it fits perfectly in the hole. Check around for suppliers that have "pellet" or "rice" sizes instead of blocks.
3. Ask for "food grade" dry ice (compared to "industrial"), the FDA does regulate the food grade ones for impurities.
Thanks for taking the time to share! Just the alternate solution for me to refill my Sodastream cylinders :)
I'm glad you said this. Reminds me of my school days when the teacher asked me which weights more, a pound of feathers or a pound of lead.
33 oz of CO2 dry ice = 33 oz of liquid CO2
CO2 is either -78 degrees C solid or gas No liquid state ever
This is great! Getting the top off the first time was the only hard part. I even get leftover dry ice from where I work for free. Plus the dry ice they have is tubular in shape so the pieces fit right in the bottle without having to crush. I do weigh it out to be more precise though so I don't blow the safety valve. To sum it up...all my refills for free thanks to Stetkal and simple applied science!
By the way! Thanks again for the tip. I recently came across about ten boxes of syrups, mostly 5 gallon size, paid $100 for all. Dr pepper, Root Beer, Sprite, Hawaiian Punch, and some that don't need carbonation, like Tea, and Country time lemonade. But this saves a fortune. I just filled my tank today.
Thank you!!! I just refilled my 130L tank for $5, saved me $25!!!!!
i wish i had been the one to have this inspiration. brilliant! i've done it successfully twice now. i did go down to the local hardware store to purchase a replacement O-ring (13/16" x 5/8" x 3/32") first, though: the old one was flattened from being so tight. O-rings seal quite well and the valve does not have to be as tight as it comes from the factory if the O-ring is replaced...makes it easier next time around. PLEASE USE A SCALE! it could go BOOM if over-filled and relief valve fails!!
Thank you for all the feedback everyone. I feel the company lied to me when I bought this mashine, that's why i came up with this prosses. There is no way it costs $20 to fill this cylinder. I love to stick it to the man! (=
Great idea!!! But for safety and to prevent damaging your cylinder it might be a good idea to weigh your cylinder while it is still full and again after you add the dry ice to make sure it weighs the same as when it was full as to not overfill it.
Nice dude! Thanks! Was going to buy refills for my dad for his birthday. But if this works this is so much better! Thanks!
great video, saved me $40 already.. I had some doubts, but this is great..
your a new addition to my smart folk list , great vid
you forgot the crucial step of WEIGHING how much dry ice you put in...
those co2 bottles will have a weight printed on the label, in usually grams or ounces, i believe soda stream 60L bottles have about 410 grams of co2. so you need an accurate scale, then you put the bottle that you want to refill on the scale, then you zero the scale while the bottle is on it.
then keep putting in dry ice until you Have the 410 grams of dry ice. or whatever the bottle has printed on the label.
if it says 800 grams of co2, then put 800 grams of dry ice into the bottle.
then seal and tighten up the fittings on the bottle, and wait for the dry ice to turn into its liquid state as co2.
exactly what I was thinking. there was no mention or write-up in the description of how much to use. the last thing you want is for that aluminum canister to blow up in your kids face while making a sodawater because it was over filled.
the valve on the side of the pin valve is a bust disk. it will release all of the pressure in the bottle at 3000 psi. so the worry of "overfilling" isn't that dangerous. however, it's still a good idea to measure the weight of the dry ice
+Bruce Sexzual True, but safety features are known to occasionally fail.
Sam Sereda agreed. hence why i said it's still wise to weigh it out. although burst disks are extremely simple. they have no moving parts. so i would think failure on one of them is extremely rare.
Indeed
Thanks Man!!! been refilling my paintball tanks @ home!
Thank you for answering. I just used the machine tonight on water only and since there was more fizz in the water than store bought fizz water, adding the dead cola brought the fizz level to about perfect, to my liking, maybe I won't have to try explosions just yet. LOL
From Colombia. Thank's my friend!
Dude, you are awesome! I'm going to save up a few empty bottles and then do my own refills. Cheers!
Excellent tutorial. Thanks.
The safety valve is actually a rupture disk membrane that is designed to rupture at a set internal tank pressure level less than the tanks. Markings on the actual safety valve body or tank indicating the set point where the disk would rupture and release the contents versus a tank failure. My Sodastream 14.5 oz tank stamping around the collar indicates several important facts that shows the tank is rated at 124 bar (1 bar=1 atmosphere about 14.5PSIA) 1798 PSIG. Great Video, thanks
I bought ice at my local grocery store Albertsons on the west coast USA. I just estimated that if my bottle holds 34 oz. of gas (listed on the bottom of 130L bottle) then I needed 2 lbs. or 32 oz. of dry ice. I believe the 60L bottle uses about 16 oz or 1 lb of gas/dry ice. You will get a standard charge if you fill the bottle up to the right amount of ounces. Good luck!
Love this. It reminds me why I want and need a guy around the house. ;)
do u realize what u have done here its AMAZING this has soo many other implacations wait till i tell my pot growing friends and i actualy got here look how VW is planing on using CO2 as refrigerent u just solved it and its is soo simmple NOW can we tern it back to a solid form with little loss VERY GOOD JOB!!! =3-
My 2 cents gloves would be a good idea and I bought a used food processor to breakup the dry ice works great.
Thank you Zachary..I found out last month that I can not have any carbonation whatsoever in my stomach. Had surgery..Chemo tore up my stomach..Thank you for taking the time to advise me, though.
Be careful. The first time I did this, it worked great. I only got a few inches of dry ice in the bottle. Next time I had a better funnel, pulverized the dry ice more, had more dry ice to start with.
I filled it up to the top! I also blew out the safety seal. I've done it again since then, only filled the bottle up about 1/3 of the way. Getting a new seal was a pain, finally found one at a paintball store.
I am definitely going to try this!
this worked amazingly to anybody considering This please do it
I can't even find a store near me to exchange them. Thanks for the alternative solution.
Bed Bath and Beyond
I usually fill them 2/3-3/4 full of dry ice and it works out perfect.
I found a simpler method for crushing the dry ice. I break it up to ice-cube size and run it through my snow-cone Ice grinder. Makes it the perfect size to gently pour into the funnel and it goes right into the bottle with no hassle.
Wow, this is AWESOME!
Interestingly, the quality of the bubbles from the dry-ice filled tank is different, I like it more. The water carbonated with the original tank had large bubbles, like the inexpensive canned seltzer I (used to) buy from my grocery store.
The water from the dry-ice tank has very fine, small bubbles, a lot like Perrier. Both are fine, but I like the smaller bubbles a little better (I'm no snob, I think...)
great video!
Awsome DUDE... I'm trying this today!
I just tried this and it worked out great. To make it easier just get a decent size pipe wrench and adjustable wrench. Use the pip wrench to hold bottle and it opens up easily. Just make sure to open the safety valve on side to bleed any co2 out. Then fill with 14 oz of ice ( little less than pound). Then seal it back up and set it outside. It perfectly works ok and with it resting outside if something does go wrong it is not in your house.
agree with put it outside or in garage. I personally don't see what the huge deal is when filled with proper amount of dry ice. I just had a 20 paintball tank filled - I weighed it empty, factored in the 20oz weight and Sports Authority filled it precisely to the limit. So....my thought is, you must weigh your empty and calculate accordingly to the weight the cylinder holds. I'd under fill a bit rather then over fill to be safe. Oh, I got that top off with a long 5/16 open end wrench and managed with the one tool. I'm female, 55 and if I could get that thing off, anyone can.
Great video. I refill all my own paintball tanks with a home filling station and a large liquid CO2 tank and was thinking about using that for my sodastream machine, but concerned about crap in the tanks from the welding supply house. Have you ever noticed any strange tastes? Dry ice is normally make from the "waste" gas of the filtering process at the plants. Has a lot more of the pollutants in it and I know it makes a big deal in the home brewing industry. There are a lot of articles that talk about using beverage grade, industrial grade, medical grade and dry ice for pressurizing kegs. Cheers
I have never noticed any strange tastes and I mostly drink just carbonated water.
My dry ice comes from a ice supplier directly. It is advertised as safe to place next to your food in a cooler. Thanks for watching. Cheers
May I suggest use a marker to draw a reference line before unscrewing the top.
For 20 oz CO2 tank, do you use 20 oz dry ice? Would that get about same pressure when room temp?
This is a good practical knowledge and great science knowledge for many.
I see pldoolittle has filled in some physics & math data to this respect.
I see that Grant Gabler also collaborated on using this techniques to fill in larger tanks.
Thank you, stetkal and all, for great collaborations and sharing.
Yes- On my second tank refill - I refilled full with dry ice. Next day it was empty. Checked the safety valve and the little copper disc was ruptured. The tank must have gotten too hot out in sun after melting and burst the disc. Next time I will fill about 3/4 way or so and not leave out in sun.
My first refill lasted about 3 months. Twice as long as a standard refill from Sodastream. Rog
This works well, I do it all the time with mine.
How do you know when the tank needs to be refilled or replaced?
I completely unscrewed the safety valve screw, the 10 mm bolt. underneath that is like a solid washer that tapers in....or out. I did not see which way it went in before it fell out. Any idea if that little washer points in the bottle or out of the bottle? Thanks!
I believe it's facing out of the bottle. Because of the pressure from the bottle.
U rock dude !
Same thing happened to me. If you back the safety valve screw all the way out, you may have lost the small foil round piece that completes the seal on the safety valve, when tightened. Find that piece, and put it back in.
Smart idea ... I just worry about all the contaminants that are being added through this process ... I prefer the idea using beverage grade co2 (decant from a larger vessel) ✅✅
Question: I have a 60L sodastream co2 canister and tried this method. I don't have the appropriate scale, but I bought a little over a pound of dry ice, stored it in a small cooler, and then about an hour later, used this method to put most of it in the canister.
The next day when I went to try it, it worked great. The day after that, the same, but the third day it seems like it's out of gas. I know I was at least close to full and I listened for any leaks but didn't hear any. What the heck did I do wrong?!
Gerard Di Cairano "60L" is just their estimated amount of carbonated water you can make. At the bottom of the tank you should see "410g and 14.5 oz" which is just under a lb. So you should have had a very full tank. All I can think of is that you had a slow leak. Too slow to hear. Test for leaks by putting it under water and look for bubbles. In the video he really made sure the valve was tight.
That is an excellent idea. I will experiment by just adding a little carbonated water to my freshly made juices..just to add some pazazz!! I used to add sparkling water, so why not this? Thanks! Your idea on adding the frozen concentrate sounds yummy..like with Lemonade. Can't wait.
This worked great! I just did this, following this instructions. The cost of refilling my two 130 liter CO2 tanks went from $59 to $4.5 of dry ice. I was careful to use a digital scale and make sure I did not overfill (max 935g dry ice for the 130L tanks).
Epic Miller...make sure you secure the safety value at the end and the cap will need to be tight.
I refer you to my comment from last year: If you have concerns about the chance of over filling your tank I suggest buying a digital scale, you can then zero out the weight of the empty co2 bottle then simply put in 410 grams of dry ice. Also you do not need to put the valve on that tight. They over torque them at the factory to dissuade ppl from filling tanks them selves. Place valve on finger tight, then use wrench to hand torque it the rest of the way. If your not confident on the amount of torque then tap firmly on the table once or twice. If you have any doubt's, I own a dive shop and have been refilling tanks for 20 years. Using these instructions you can safely refill your co2 bottle for many years. O rings can be found at local hard ware stores I suggest finding the right replacement and have some on hand just in case.
*+Michael+ {{I own a dive shop and have been refilling tanks for 20 years.}}
excellent, hopefully you can answer my question.
since liquid CO2 is at a constant pressure of, I think 1200#, no matter how full or empty the cylinder is then why cant you fill the cylinder up all the way to say the shoulder of the bottle leaving a little air space above for any margin of error?
the pressure should be 1200# if it's over filled or half filled. am I correct?
that way, you can fill the bottle past the 14 oz weight and have to refill less times, correct?
.
.
When the cylinder reaches 87.90 F the entire charge becomes a gas no matter what the pressure. A fully charged CO2 cylinder at 87.90 F will have an internal pressure of approximately 1100psi. At 1200 F a fully charged CO2 cylinder will have an internal pressure of nearly 2000psi, this is greater than the designed service pressure of 1800psi of the cylinder. Remember that this cylinder at 1200 F has an internal pressure greater than the marked service pressure of the cylinder and is properly filled, not overfilled. Also note that 1200 F is not an excess temperature and can quite easily be reached in many different environments (i.e. in a shed or a vehicle on a hot day or in a kitchen).
where in the world can a shed or kitchen reach (1,200) one thousand, two hundred degrees? something is wrong in the translation here.
+AZ DONALD I'm away from my pc will edit later. Either way over filling of the cylinder is dangerous. The manufacturer has supplied their recommended fill capacity. If you over fill and damage the machine or cylinder it would most certainly void the warranty.
Thank you so much for the video, but just 2 questions:
-
1)Can the dry ice be weighed first then put it in the tank?
2)Can the bank be slightly under filled instead of the exact indicated weight on the tank?
So I just figured something out with this method. I have done this about 5 times so far and this is the first time I ran into this problem. If you OVERFILL the tank, it prevents the tank from working! It creates too much pressure for the machine to push down on the valve to release the Co2. If this happens to you, simply use the relief valve to empty some of the Co2 and you are all set!
the pressure is determined by the vapour pressure of co2, so it wont change by overfilling it, only with temperature. I wonder why overfilling it stops it working?
***** Because the liquid Co2 expands and contracts with temperature. In other words, if you will the bottle completely and don't leave enough gas space for expansion the bottle could explode. That's what the safety burst disk is for. The thing is, the disk is set to rupture at a higher pressure than some Sodastream models can handle (plastic lever and pin depressor) so you could end up with a situation as described above. You are almost correct about the vapor pressure to temperature thing, but failed to also consider the fact that even as a liquid, the Co2 still expands and contracts with temperature. This is why LPG (propane) tanks have an 80% max fill limit. You need the extra 20% available as expansion room when the tank is exposed to higher temps than when it was filled.
Hope this helps!
Thanks for the tip!
I have not read all the comments here, but I have found it VERY SIMPLE to use my SNOW CONE MACHINE to break down my dry ice - then it is just a simple slow pour into the funnel and into the bottle.
Also: I have 2 30's and a 60L so I get around 5 lbs of dry ice from Fred Meyer @ $0.99/lb. and fill the 60 and a 30 usually the weekend following inserting the last full 30. Extra empties are pretty cheap on Ebay.
Snow cone machines are cheap but keep your box and receipt just in case.
Worked first time I did it. Last 2 times (2 different cylinders) gas kept leaking from the release valve. Only filled with 8 oz. last time to make sure I wasn't overfiling. Any ideas as to why it leaks from the release valve.
Seeing how I was just given an old 50-pound CO2 cylinder of a type apparently not used anymore, which makes refilling/exchanging out of the question, I figured this would be a good method!
That is pretty smart
add 140 grams or 5 oz or 1/3 of a pound of dry ice........the neoprene [rubber] O ring makes the seal not beating the valve....so good and tight is sufficient
A demo of your homemade CO2 on your Sodastream would've been cool.
Thank you for sharing. Now im sure this will work with my CO2 extinguisher.
To add to what you said, sticky liquids will also gum up the pressure release valve over time, and eventually the bottle will explode and possibly cause injury.
Do you know the exact quantity of dry ice you used? (or are you saying the cylinder should be full when you are done scooping in the chopped DI?
We refilled two tanks for the first time today. We put very close to 14 OZ in each but I cannot get the small relief valve to stop leaking. It is impossible that we put too much dry ice in it as we only bought 2 pounds and we weighed everything before, during and after. Any ideas?
amazing! THANK YOU so much!
thanks for uploading.. i tried this today and was so nervous, but it went well.. except i ended up removing the safety valve and a little piece of metal popped out.. it's concave and I wasn't sure whether it should curve in towards the bottle or away.. any ideas?
YES! since a preasure builds up immediatly.. If it is closed the only way for it to escape while screwing on the valve is through the not yet tightend valve.. This could lead to blowing out the O-ring and hence breaking the seal.
THANKS! Great idea
Brilliant!
Awesome thanks man
You are welcome.
Check the tank for a stamped pressure rating, (which may be a DOT code. Then do the math for the pressure...or assume that, as usual, that the tank is rated for100-200% over-pressure. CO2 does reduce in volume as it cools, so the solid will take a bit less rom than the equal weight of liquid.
Easiest way to be sure is to weigh the solid powder before filling.
But pressure tanks that are DOT rated are always rated way under the bursting pressure.
If you don't like burping, use N2 instead.
Anyone else out there who has attempted this method. I'd love to know how it went. Does this actually work out, if so, how well and for how long?
I've read of people getting connectors which could ultimately bypass risking the dangerous. I'm all about the most economical way, however if there's a safer more economical way I'd appreciate your sharing.
I lol'd through this entire video. I was SO hoping that something was going to explode.
Have you had any O ring leaking problems through the years by doing this. I'm concerned about the O rings getting brittle or developing a crack due to the super low temperature. In this case I could buy a replacement designed for these temps. Has the one installed with the sodastream cylinder worked fine?
The orings should be made for that temperature. When refilling with liquid co2 the tanks also freeze. For safety turn one in every once in a while.
Thanks so much for sharing.
Ehhhhhhhxcellent. Tanks a lot.
No. Just no.
worked perfectly for me
